However when I try to upgrade by redsn0w custom IPSW and JB it I found my Cydia keep crashing!!! Cydia opened and try to load things by itself and once it finish the “Reloading” then it crash back to springboard. I need HELP!

  • Besi

  • James Watts

    My iPhone keeps crashing when rebooting after installing Ultrasn0w 1.2.5. It wont boot up at all.

  • Jesus1972maza

    I think Ultrasn0w will never find the way to unlock the newer baseband’s . last time they come out with an Unlock it was for 4.0. How long ago??? over a year. I feel sorry for my self and all the other people Waiting for the solution for my iPhone 4g..

  • Besi

    try this.. tethered boot

  • Annie081994

    I can’t find the ultrasn0w in its repo. I’ve tried restoring, rebooting, and rejailbreaking my device but nothing has worked.

  • Annie081994

    nevermind i found it! :D

  • luis angel macias

  • Dee Kulik

    I just used the new Redsn0w last night to jailbreak my phone. I have a 3Gs IOS 5.0.1 with baseband 05.16.05. I’ve never been interested in the jailbreak as much as the unlock. I know you have to jailbreak to unlock however. All I want is to use the iPhone with a T-Mobile Sim Card. I’ve been waiting since 11-11-11 to use it. Of course I had no idea how involved it was to jailbreak and unlock. I’ve become somewhat of a pro. : ) However, I have no idea about the baseband. There I am clueless. Anyone can give me info of what I might need to do to unlock my 3Gs? Thanks everyone!!

  • Football truth

    Does it work with baseband 4.11.08? Did they come out with any program that can downgrade the firmware

  • Pakipride

    My baseband is 4.11.08 and i guess it won’t work so now my question. is it gonna be available for this baseband any time soon or no ???

  • Pakipride

    Sorry forgot to mention its iphone 4

  • Jeff Mansell

    Head over to Settings, General then about on your phone, almost at the bottom you will see the “Modem Firmware” if your firmware is any of the above in the article, you can unlock with this. Hope this helps.

  • Jeff Mansell

    You didn’t preserve your baseband and now you are upgraded. No going back. Gevey Sim only or wait for 4.11.08 unlock. Sorry. I’m in the same boat and it sux!

  • Caominh

    # Baseband Wait promising

  • Didie

    currently i have iphone 4 running ios 5 with baseband 4.11.8.
    i just wanna ask if i upgrade to ios 5.0.1 , the baseband will change to what ?
    because im afraid if i upgrade it, my iphone cant be unlock =(

  • didie

  • didie

  • Anirudhthadeshwar

    No it does not.
    And there are programmes that downgrade your firmware but they cannot downgrade your baseband.

  • MikeA

    Hey is there anything that I can do to unlock my I phone 4 IOS 5 Base band 4.11.08 ?

  • DaddyVeNoM


  • DaddyVeNoM

    i mean…

  • Jphockey6

    When will the unlock come out for baseband 3.10.01???

  • darius

    maybe one day, maybe…

  • Gogreeall2010

    When will the untethered jaulbreak come out? I am stuck on the “mounting rootfs as read-only ERROR!”
    I first jailbroken and unlocked it, but no service and invalid sim. I tried to re-jailbreak again. That was how I got stuck. I would greatly appreciate if anyone can shed some lights on this one.

  • Shadowv50

    Well you d’ont need to jailbreak it again,just keep to reinstall ultra snow or try to go on airplan mode on and off.

  • KycT

    what about upgrade to 6.15.00 ?

  • Naseem Abourachid

    i have a 3gs im on baseband 06.15.00 been waiting for this update a while, installed earlier today but still nothing, i rebooted tried airplane mode! any other ideas guys? all i get is searching and carrier settings wont load either!

  • Dj

    I can’t get cydia to load repo666 and therefore I can’t get the new ultra snow. I doubt it will help ne way. The ipad baseband is effed up!! it is bad enws!! I think apple is purposely signing 4.1 to gather data on jailbreaking to try and put a end to it, cuz ever since they been doing it shit been weird as all get up for my adventures of jailbreaking

  • Naseem Abourachid

    after messing about with it for 30min it works! i restored on itunes then did a jailbreak using latest redsn0w then when setting phone up disabled location settings! get in so chuffed well done guys keep up the good work!!!

  • Mmm

    “NO Service” at iphone 3gs 05.13.04

  • Mmm

    after restoring its work ,, but u must take backup :S

  • Skipper Ross

    We really need unlock baseband 04.11.08. Is there a patch coming along (soon)???

  • Patrick

    I have a 3GS (baseband 05.13.04). My doubt here is how to restore without upgrading the baseband. I was reading that some people had this problem and, as it seems, there’s no solution…
    So that, I’d like to know if someone can explain me what kind of procedure I should do to preserve my current baseband. Thanks.

  • Reyes Isven

    we need need help with our basebands 04.11.08… i cant believe it. Meaby its only a commercial trick; the solution its here waiting for a price, or waiting the high sales of new iPhone 4s…

  • Tbulsara

    create a custom firmware using redsn0w and that will not update the baseband. it will still be a tethered jailbreak unless the 3gs is old bootrom!

  • victor152

    same thing

  • Dee

    Really disappointed. My friend gave me his old iphone 3Gs. I’ve been waiting impatiently (lol) since Nov. 11th to jailbreak…but mostly just wanted to unlock and use with T-Mobile. I was excited to jailbreak using new redsn0w. Now they come out with an unlock, but unfortunately my baseband is 05.16.05. Guess I don’t get a Christmas present this year.

  • Football truth

    I thought the firmware was the same as the baseband

  • Dee Kulik

I do want to thank the people who work hard working on the jailbreaks and unlock. I know it takes a lot of time and brain power. Good job guys!! Keep it up.

  • Kash

    I have an iPhone 3GS on iOS 5.0.1, baseband 6.15.00. I have followed all the steps, inc. a tethered boot but it’s still saying ‘no service’. Want to unlock my iPhone FAST. NEED HELP!!!!!!!!!

  • Ted4bz

    Thanks for the new jailbreak but, I jailbreak 3Gs new bootrom baseband 6.15.00 with 0.9.9b9b and installed ultrasn0w 1.2.5. I rebooted but the device search for about 5 or 10 minutes and then gave up, the result is: “no service”. I am grateful for the free stuff but I am sorry it didn’t work! What did I do wrong? What do I do now?

  • Patrick

    Thank you for the information.
    I did it and, in theory, everything was fine. Nevertheless, after jailbreak it, it shows the apple logo first and after some time appears that small circle (the same as when you turn the phone off) and stops there. It’s been about 2 hours now, hehe.
    Can you help with it? It appeared everything was fine until now. Thanks.

  • Annie081994

    same here too :(

  • mohammed sinan

    same me

  • Alban Pajova

    same here, it’s not working

  • Alban Pajova

    same here

  • DiscoStubert

    it didnt work and my iphone 4 died so i restored using itunes and now have modem firmware 04.11.08 ahhhhhhhhh

  • Drake

    Can anyone tell me when there going to come out for a unlock for the iPhone 4 5.0.1 BB 3.10.01?

  • Patrick

    After updating the software, it asks me to put a valid SIM card (I don’t have it).
    So that, I tried to jailbreak it anyway.

    Everything looks fine, but when the process finish it doesn’t start again. It appears Apple logo and, some time later, the loading circle you can see when you turn the phone off. It stops with this loading and nothing else happens. I’ve tried twice the process and the result is the same.

    Any clue? Some idea about how I can activate the iPhone without the SIM card before jailbreak it? (the original SIM card is from Spain and I’m in Brazil. It’d be quite hard to find it here).

    If there’s no way to make it work, I’d like to know how I can restore it with the backup I’ve created before without upgrade my baseband. (if you could indicate me some article about it I’d appreciate…)

    Thank you for your help.

  • Drake

    I had the same problem I just restored it… im lucky mine was new and i didnt have much on the phone

  • Sailas2006

    In redsn0w hit extras then just boot tethered and follow the on screen instructions.

  • Patrick

    Well, now I was able to finish the jailbreak.
    Nevertheless, I need to know how to activate it without the original SIM card. Any idea?

  • Jimloplus

    por fin tengo mi iphone 4 Americano Att unlocked y ahora lo puedo utilizar en Mexico con Telcel, muchas gracias Iphone Dev Team por este regalo de navidad

  • Skipper Ross

    Patrick, you are going to need to check the bb version. If it is not listed on the above article, it is not yet supported. I have the same problem, my baseband is not yet supported, I jb and unlock it, but it still does not recognize any other sim card.
    You can find the version under: settings/general/about/modem firmware

  • Patrick

    No, but my BB is supported (05.13.04).
    It looks everything was fine, but now I have the first screen where it asks for a valid SIM card to activate the phone (after that, I’ll be able to install ultrasn0w and unlock my iPhone).

    What I need to know now is how to activate the iPhone (after installing iOS5.0.1 and jailbreaking it) to be able to use it and install ultrasn0w…

  • Edgar Vrgs

    iPhone 3gs 5.0.1/ipad baseband keeps searching after 30 mins still nothing? does anybody know how to fix this?

  • Renico van Wyk

    Same same. Thanks for the free stuff anyway. Cant wait for the unlock to work. Bin outa an iphone for a month now!

  • Patrick

    Well, any tip about the next step after upgrade the the iOS and jailbreak it? (considering you don’t have the original SIM card to first activate the phone)
    I can’t follow the step 2 because I can’t access Cydia…

  • Renico van Wyk

    On what carrier are you? Mine is not working.

  • Gluestar

    Hey there,
    first off, thanks guys for the excellent work!

    I just got T-MOBILE WORKING on my 3gs (baseband 6.15.00): I followed the instructions above and added a few things from some other past instructions that I’m positive made the difference (I had similar issues to comments below when I tried unlocking last night I.E. searching for network forever, or no service/carrier).

    1. went through the process of rebooting 5.0.1 through Itunes
    2.reflashed the baseband (anew) in Redsn0w to 6.15.00
    3. disabled 3g and Cellular data in Network settings BEFORE DOWNLOADING ultrasn0w.

    and then did everything as mentioned in the instructions above. I still gotta see if my data plan is working but I’m happy to simply have my iphone to make calls again!

  • Vietplus

    I got it to work

    happened the same to me. I finally got it to work by following the steps.
    Open redsn0w 9.9b9 choose your ipsw and go to jailbreak uncheck all except deactivate. It will do it things and then stop at error. What I did was just boot tethered again, once your phone turn on then go to cydia and search for ultrasn0w 1.2.5 and install it again. I hope it will work for you, if it doesn’t try to reset your network in the phone and try the steps again.

  • Michael Lambert Otis

    You can update to the 06.15.00 baseband which is supported

  • Gluestar

    Yep, everything is back to working!

  • MAK

    Same here, need help…

    The iPhone 3gs running 6.15 baseband and get the NO SERVICE MESSAGE, should try these:
    Restore iphone- jailbreak it- And check again ´´install iPad baseband´´… Yes, even if you already did it. ITS NECESSARY TO DO IT AGAIN! Install Ultrasnow and thats it.

  • aman virk

    ultrasn0w 1.2.5 nt working on iphone 3gs old baseband 6.15 and ios 5.0.1

  • Dee

    Thanks for the reply Michael. I’m not clear on how to update the baseband. It also scares me because I’ve seen articles here where people say they still have “no service” on their phones, or it’s bricked. I don’t want to screw up the phone. It was a gift and I’ve been so anxious to unlock and use my TMobile sim. Maybe I need to be more patient and see if someone comes out with the support for the baseband 05.16.05. I’m used to having “crap” phones and would be nice to have a working iPhone. Thanks again for the reply and “Happy Holidays”!

  • Aman virk

    plzzzz help

  • Alban Pajova

    Install the baseband again, that’s what worked for me. I used ultrasn0w 0.9.9b8

  • Alban Pajova

    Yup, after 3 weeks of frustration, it dawned on me, let me try installing the iPad baseband again, and yup it worked.

  • Alban Pajova

    mine worked without turning off the data and 3G, installing iPad baseband again did the trick.

  • Alban Pajova

    well, you just needs to install the iPad baseband again, that’s what did the trick for me.

  • Alban Pajova

    a jailbroken device is hacktivated meaning you can bypass activation.

  • Alban Pajova

    A jailbroken device is already hacktivated meaning you can bypass activation.

  • Alban Pajova

    FOUND THE SOLUTION: install the iPad baseband again.

  • Kash

  • Patrick

    Thank you. I don’t know exactly what’s happening here, but I’ll keep trying.

  • Patrick

    It works…
    Thank you for your help. Great stuff…

    Last question. The semi-untethered jailbreak doesn’t work with iOS 5.0.1? I was searching for Semitether in Cydia but I didn’t find it…

  • EuroGiant

  • Kisfenyoke

    how to install ipad baseband???

  • iphoneguru

    4.10.01 is unlockable by using Gevey SIM. They are like $5 on amazon.

  • iphoneguru

    you can downgrade to 4.1.0 but i think your baseband wont change. Are you using an Iphone 4 or 3gs? If you are using iphone 3gs you could jailbreak and install ipad baseband using redsn0w and then install ultrasn0w via cydia.

  • Dick

    i think the best answer would be never

  • Giancarlo Vega

    I still no get my iPhone 3Gs 5.0.1 baseband 06.15.00 unlock. I do it step by a tep and when I insert the chip it says “No SIM Insert”. Can anyone help me please?

  • Tashtm99

    I actually did a different way which is easier, when u go on cydia go to sections and scroll down to utilities then scroll to the letter u and ultrasn0w is right there hope this helps

  • Anirudhthadeshwar

    go to Settings > General > About.

    the VERSION is your firmware.
    And the MODEM FIRMWARE is your BASEBAND.

  • Anonymous

    I tried unlocking my 3Gs new bootrom bb 6.15.00 on ultrasn0w 1.2.5 and redsn0w 0.9.9b9 and then tried with 0.9.9b9d but it did not work the result is: ‘no service’ each time. I tried several times starting with iTunes restore ios 5.0.1, but it did not work. So what did I do? I jailbreak with redsn0w 0.9.9b7 and unlocked with Ultrasn0w 1.2.4 as the first steps Then I jailbreak with 0.9.9b9 and unlocked with ultrasn0w 1.2.5. I repeated this procedure three times and it worked three times!

  • Toiletlife

    Just Try to instal ipad baseband again, you can search that from google…..and if it doesn’t effect try to remove Ultrasn0w 1.2.5 and reboot with redsn0w or ibooty, and then instal ultrasn0w 1.2.5 and reboot it again and then wait for a moment like 1hour
    if doesn’t change anything, just email me…

    I need to update by baseband to 6.15.00 from 05.16.05. Is there a step by step explanation how this is done? I was able to jailbrake my 3GS with 5.0.1 and tried to unlock it with ultrasnOw but continue to show “no service”. Any help would be appreciated.

    Go to YouTube and search a video that shows a iPhone 3GS showing searching. Even if it doesnt have no sim card. I had the same problem. But i fixed it

  • Haxx

    Keep searching, 3Gs, what should I do?

  • miracle

    Do you have a link of that video? I’m having the same problem here.

  • h singh

    Hurray!! People who are not able to unlock their iPhone 3GS on 6.15.00 baseband….follow this.

    You must Jailbreak your phone by using ‘install Cydia’ and ‘install ipad baseband’ options and then try to unlcok using ultrasnow 1.2.5.

    Restart your iphone and it’s done. Network is back and working!! Hope this helps…

  • Eas

    you jailbreak your phone with what version of redsn0w? 0.9.10b1 ?

  • Lam Phan

    if i check install ipad baseband, it will warn me that “the ipad baseband is not compatible with iphone3GS units manufactured week 35 of 2011 or later. If this an iphone3GS and if digits 3-5 of its Serial Number are “135″ or later (xx135…), then you should NOT proceed!”, so should i dare to proceed anyway?

  • ipadking

    reinstall your baseband again

  • Mohammad

    I think you need to check and update your baseband (Modem Firmware). Would suggest to update your baseband to 06.15.xx. I jailbroke my iphone 3gs with IOS 4.1 and baseband 06.15.00. and then unlocked works great.


  • FML

    does it work for firmware 04.11.08

  • LLJ

    i tried both 0.9.10b1 and b2.. both disappears after saying fetching for ipad baseband..

    I followed the steps. But it takes long time to searching for signal! So what does that mean?

  • ajs

    I’m having the same issue…searching forever for a signal and it seems that the phone is still locked. Should I be doing the jailbreak and unlock with or without the SIM card in?

  • Kimb234

    Okay, so my issue is, I can jailbreak, and download cydia, but in your screenshot, you show the iphone connected to the internet…that’s the issue! I”m jailbreaking and unlocking so that I CAN get service. Right now when I go to cydia, it says no service. Advice that explains how to get around this would be great!

  • Afrorat1000

    I had to firstly install ONLY the iPad baseband, then install ONLY cydia both using redsn0w 0.9.10b
    Worked for me!

  • hris

    I’m in the same boat. I show “No Service” on the status bar. Carrier is not showing up nor the SIM card is being recognized. Under the Phone options in Settings, I still see AT&T services being shown. It looks like some kind of flushing needs to be done to get rid of the original carrier settings and make the phone understand any other SIM is also valid. I would love to see some help on this. Thanks!

    My baseband is 5.16.05 and i just jail broke my iPhone 3GS. But i can’t unlock it. Is there a way to unlock on this baseband or to change the baseband to 6.15.00 ? Plz help

  • hris

    Use redsn0w 0.9.10b3 to upgrade your baseband to 6.15.00 and then unlock using Ultrasn0w 1.2.5 which you can get under Cydia app on your phone.

    Caveat: You will find many including me having trouble getting the new SIM to work on unlocked phone unless you update the iOS to custom iOS built by redsnow. Even after unlock the phone doesn’t seem to get signal from any other carrier.

  • pepe

    can’t find service after using ultrasnow have baseband 6.15.00 as well a

  • h singh

    Actually mine is 41 week so it worked buddy. I am so not sure about yours so its upto you to give a try. In opinion it should work….good luck!!

  • Nguyen Anh Tuan

    Hi guys, for anyone who got problem with 3gs 5.0.1 with ipad baseband 06.15.00 still Searching…… and No service you can try this, first remove Ultra Snow 1.2.5 and reboot, Use Red snow 0.9.10b3 to JB your phone again, CHOSE Install Cydia and INSTALL IPAD BASEBAND (note this way did not work with 3gs after week 35 of 2011), and do this like usual, when done, reboot your device, install Ultra Snow 1.2.5 and reboot, and you made it. Good luck.

    NOTE: to avoid getting error when JB with Reds now 0.9.10b3, you should first download Stock FW 5.0.1, and in Red snow 0.9.10b3 select Extras > Select IPSW and choose the 5.0.1 stock firmware yo have just downloaded.

  • Adoo56

    so you have the Gevey ,you ll not have any problem for unlocking if you just preserve your baseband for 5.0.1 as 4.10.1, actullay mine is exactly as yours and i m still not sure if Gevey really works or not !!

  • Tipipepper

    My 3gs (week 44 of this year) is running on 05.16.05, its JB but need to unlock, i don’t want to upgrade to 6.15.05 as its too risky! Any ideas of when i’ll be able to unlock using Ultrasn0w?? thanks :)

  • Lam Phan

    I did proceed it anyway though my phone is quite old, and it works on unlocking. You can give it a try, but make sure that you know what you are doing. Once you change to iPad baseband, you can’t change it back. Good luck!

  • Lam Phan

    Give me your email, and tell me your situation, so I can help. Basically what i did:
    1. Use redsn0w0.9.9b7 to enter pwn DFU
    2. Install custom IPSW on iTunes
    3. jailbreak your iPhone using redsn0w (newest version) WITH “install iPad baseband” checked.
    4. install ultrasn0w 1.2.5 on Cydia.
    5. Reboot. Done!
    Before doing those, my iphone 3gs was 06.15.00 bb. If you install iPad baseband, you can’t change it back. So make sure you know what you are doing.

  • Anonymous

    I have tried this on 2 different 3gs. The first on worked perfectly (and still is). The second one worked for two days and then started saying Invalid sim. I did a restore and tried to jailbreak and unlock again, but it constantly said searching.

    On putting the correct sim in the 3gs it would not activate, so I tried several other sims and it wouldn’t recognise any of them. Did a bit of Googling and this has happened to other 3gs users :(

    Took it to Apple to see if they could activate it for me, but no luck there either. One broken iphone.

  • Peter Berson

  • Ricky-v

    I have same 3gs installed ios 5.0.1 baseband 6.15 and i get service!!! You need to try reinstall the Ipad baseband again and by patient to upgrade Cydia properly ! Try reinstall Ultrasn0w again ! Good luck but is work!! True is i spend 10hours get it work!!

  • Anonymous

    I’m starting to think my iphone 3gs ios 5.0.1 baseband 05.16.05 will never be more than an ipod. Which I already have. I’m not that savvy to update to the 6.15.00 baseband and there seems to be too many complications with it amnyway. Never thought it would be that difficult to unlock. I could care less about the jailbreak, it’s the unlock that I want. Just to be able to use the iphone (was a gift from someone who got the new iphone 4s) as a phone is all I ever wanted. I’ve just about given up hope!

  • Anonymous

    See my latest post. I have the same phone, ios, and firmware. I’ve pretty much given up hope on an unlock for that firmware! Have a Happy New Year, maybe the year will be better for iphone unlock. : )

  • Sean

    This happened on one of the iPhone 3GS’s I was working on. I managed to get it working by doing a tethered boot through Redsn0w. If you’re still having issues, re-flash the “no_bb” iOS 5.0.1 and start again.

  • Sean


  • Sean

    There is still no unlock for 4.11.08. There are some rumors about a sim solution like gevy sim (vold miracle), but no release date. Best solution right now is to sell it and buy another that’s already unlocked.

  • Nerob_chowdhury

    Maruf : Dont be worry brother….if ur using 3gs Just use redsn0w 0.9.10b3 and select the install cydia and ipad base band at a time if there any error massage shows about firmwere just ignore and after install cydia and ipad baseband just install the ultrasn0w 4.2.5 …..u will get the network 100%

    Ive tried to upgrade my baseband to 6.15.00 through REdsn0w on my 3gs ios 5.0.1 with bb 5.16.05, It would not work and kept hitting error message (60000 ms) any suggestions to get past this?? I had to reboot several times as I lost Cydia and my itunes library, its frustrating as i need to use it as a phone not just an ipod touch!!! Does anybody know if Ultrasn0w will EVER be able to be used on baseband 5.16.05??? Please help!! If i cannot unlock it i will have to sell it as i need the use of the phone!!! Thanks!!

  • HeyMattWei

    What I did with my 3GS that was upgraded from 5.0 tethered (and worked unlocked) to 5.0.1 untethered (and didn’t unlock) was re-flash my already 06.15.00 baseband. I just used redsn0w 0.9.10b3, clicked ‘Jailbreak’, entered DFU mode, clicked ‘Install Cydia’ and ‘Install iPad baseband’ (my model number is 88131), and waited. I reinstalled ultrasn0w using Cydia, and after a UNTETHERED restart, all my text messages came rolling in ^.^

    I applaud the guys working on the jailbreaks and unlocks. But I’ve been waiting and waiting for an unlock and never thought it would take so long. I’ve just about given up as you can read in my last message. Too complicated, too many bugs and would have to brick it so it’s useless. Can’t afford an iphone or would buy one online already unlocked. Could care less about the jailbreak, just want to use it with T-Mobile Sim. The light is fading at the end of the tunnel…lol

    Have a Happy New Year, maybe we’ll get lucky with our phones in 2012!!

  • Anonymous

    Quick question if anyone can answer. I still have the tethered jailbreak they came out with during Christmas. Haven’t done the untethered yet and may not. I noticed last night when I plugged my iphone to sync with iTunes, said it wasn’t a valid sim (it’s not) so I couldn’t sync. Is this because I JB it and installed Cydia? I had no problem prior to the JB. Sorry, only savvy with electronic devices to a degree. I’d appreciate the info from you Tekkies! Happy New Year Everyone! Let’s hope 2012 gives us the miracle of the iphone we’re all wishing for! : )

  • Beaubanum

    Redsn0w jaibroke my iPhone with no problem. Unfortunately , ultrasn0w 1.2.5 from repo666 was unable to unlock my iPhone 3GS with 06.15.00 . Let me know if you have a solution to fix that problem. Thx.

  • Cryme_tyme_

    Hi, I’ve figured out how to bypass the unlocking 3gs problem through ultrasn0w 1.2.5, here’s the steps u need to follow – ( procedure will help overcome no service and searching issues)
    1st- Update firmware to 5.0.1 from  iclarified to get a custom file
    2nd- u install redsnow 0.9.10b3,
    3rd- when u open up redsnow it will give u 2 options- 1- jail break and install Cydia and the other option is extras, click on extras and press next.
    4th-  (select ispw) then press next and it will take u to next screen where u will need to find and select the custom FirmWire file 5.0.1 is on yourlaptop/desktop.
    6th- once the firmwire is selected (double click it), all u do then is press back to a screen where it will give u an option to install Cydia and install iPad baseband, select and tick both boxes, once u have pressed next it is business as usual to jail break etc.
    Once jail break is done, u should have a phone which is automatically unlocked now, if it isn’t just install ultrasnow 1.2.5 in cydia and reboot fone and when ur phone is back on it will be unlocked !

  • David Feldbaum

  • iNoob

    If you haven’t allready done it, do not do it untill there’s a proper fix coming up. Currently updating the baseband will lock the phone (causing: Searching… bug) and as I’ve worked on it for a week now, there seems to be no way of fixing it thus far. If you do update your baseband, and happen to get it working by some miracle do tell how you managed that :D

    I have an iphone 3gs ios 5.01 baseband 05.16.00. It still has the tethered jailbreak they came out with right before Christmas. Now I’m confused what to do because they have resn0w 0.9.10b1 and redsn0w 0.9.10b3. Not sure which one I can use for untethered and I’ll need to update basebad to 06.15.00. Just want to try and unlock. Can’t wait anymore. Been waiting over 2 months. If the iphone breaks…oh well. All it is right now is an ipod. Sick of waiting. Can someone tell me step by step what to do to try unlock? Cryme_tyme_, you seem very knowledgeable. Can you help me out? Or anyone who thinks they may be of help.
    Thank You!

    dear willow16222
    use redsn0w 0.9.10b3 to untether your iphone
    if you want to unlock it,downgrade your iphone to 4.1
    and flash to ipad baseband.
    thats it you are done

  • Spypsycho

    so these are my details, i’ve been trying this for two days. The phone recognizes the carrier but cannot find signal, after searching for a while it just says “no service”. I’ve looked everywhere but few people seem to match my case and all the solutions are for old bootrom iphones. I read somewhere that re-flashing my bb will destroy the phone permanently with the new bootrom so I have not tried that. If that has worked for anyone (with a new bootrom) please let me know. Other details:

    Jailbroken with: redsn0w 0.9.10b3 (latest version)

    used Custom ipsw to restore (with iTunes) and stock ipsw to jailbreak (custom ipsw was not accepted by redsn0w)

    Thank you for taking the time to reply Slim…I’ve decided to start from scratch and restored my iphone 3Gs ios 5.0.1 to factory settings. I’m at the gray screen that says “iphone”. I do not have a valid sim card and I’m totally clueless where to start first. I don’t know how to downgrade, flash baseband and cannot find the IPSW. I have IPSW in iTunes, but they are for my iPod Touch. Please forgive my lack of knowledge. If you could give me step by step, that would be great. I know these instructions can be time consuming. Thank you again…

  • Anonymous

    I have the same phone, firmware and baseband. You CANNOT unlock baseband 05.16.00. Only the Basebands metioned on ultrasn0w. You have to “flash” it to ipad baseband 06.15.00. I don’t know how to do this. Would have to get info from google or this forum. I’m afraid of bricking or rendering my phone as useless if I do this. Hopefully someone on this forum can help you out.

  • Amber

    i had no luck when trying to choose custom ipsw. everytime i tried to jb, it’d freeze on the apple logo. which i could NOT get away from without having to do a complete reset. i finally just skipped that step of changing ur ipsw, and did it from there. after that, is when i had the no service issue. i have a 3gs, ios 5.0.1, baseband 6.15.00, and the newer bootrom. i switched to flightmode a few million times, kept respringing winterboard, and i also help down the power button, AND the home button at the same time ONLY until the apple logo reappears, then release. otherwise you’ll put yourself in recovery mode. i’m not sure which of these steps actually fixed my phone, but it did, and it’s never been better.

  • Amber

    i also HELD**** down the power button (not “help” lol).. Sorry for my typos x_x

  • Whatgameman

    For me to try to fix the “searching” “no service” problem, I just use snowbreeze 2.8b11 to create custom IPSW with ipad baseband, risk it. and it works. Who care about GPS if you can’t use the phone to call. Hurray!!!

    Can someone HELP me with my question?
    Ok, here I go again. I used redsn0w 0.9.10b3 a few days ago. Jailbroke phone and installed Cydia with no problems. I was afraid to install ipad baseband. Now I’m desperate enough to do that. Problem is, I don’t know how to change my 05.16.05 baseband to 06.15.00. Can I jailbreak again over the recent jailbreak? I tried it a little while ago, but Redsn0w stopped responding while in DFU mode. The only option is “Jailbreak and install Cydia” The extras button is not helpful. Not sure how to proceed further. Any help from you Tekkies would be appreciated.
    Thank You…Willow

  • Robert B

    3gs serial number xx951xxxxxxx
    IOS V5.0.1
    Firmware 06.15.00
    I did a Jailbreak on redsn0w_win_0.9.10b3
    Then tried to unlock using ultrasn0w1.2.5
    Initally failed as phone continuously searching for signal.
    Decided to ‘flash’ to ipad baseband using redsn0w (only checked this box NOT the cydia box), I was reluctant to do this initially as lots of warnings regarding serial number of phone !
    Worked straight away and phone is now making calls on the Three (UK) network.
    PS I’ve never done anything like this before, if I can do it so can you !

  • Shafiqesmat

    you need to flash your Baseband as well while jail breaking your iPhone 3gs then you can unlock your iPhone 3gs by using ultrasn0w

  • bcgtechie

    Download iPhone2,1_5.0.1_9A405_Restore.ipsw and save to desktop, download and run redsn0w 9.10b3. Go to Extras, select “Select IPSW”, browse to your downloaded IPSW, it will load on to redsn0w as soon as you go back and select Jailbreak. Choose only “Install iPad baseband”… click next and follow the steps to put your phone in DFU mode. This should work… it worked for me. Once you have it updated, go to CYDIA and run Corona Unthetered so your 5.0.1 wont wipe out if phone is rebooted. Then run Ultrasn0w 1.2.5 and your phone should be unlocked. Check under settings >>general>>about if modem firmware is 06.15.00

  • Potash100

    Please bear with me. Where do i download iPhone2,1_5.0.1_9A405_Restore.ipsw. I do have my ipsw saved to my desktop. Not at my own computer to check it. It’s my custom ipsw from iTunes. I used this the day I jailbroke it from the untethered jailbreak. Thank you so much for replying back to me. Much appreciated. I’m an intermediate when it comes to all this stuff. Started out a newbie back on Nov. 11th, but still so much info. Not bad though for a 53 year young woman. : )

    Did you get a response? I have the same issue…

  • Anonymous

    Hi bcgtechie, I tried to do the instructions as you stated to me. After putting iphone in DFU mode, the dialogue box tells me it’s going to install ipad baseband. Then I get a message saying “The connected device doesn’t support untethered options”. Not sure what this means. I tried it 3x’s and still get the same message. Not sure if my 3gs bootroom is new or old. the S/N is 86001.(I assume this means that it was made week 1 of the year 2000 according to posts I’ve read.) It asks questions about the week it was made in the beginning of Redsn0w and I think I’ve answered them correctly. Any suggestions on what I should do next? Completely baffled now!
    Thanking you in advance for your help.

    When trying to install baseband 06.15.00 on iphone 3gs 5.01, anyone ever get a message saying “The connected device does not support untethered options” Let me know if anyone knows what this means. My serial number is: 86001.

    you probably need to unplug iphone, throw it as hard as you can, and get an Android phone. job done.

    You need to start all over again I’m afraid, with a clean restore, then jailbreak without installing cydia, then pwned DFU mode to use bb upgrade..(no signature hash blob)

  • Sami

    I have 3GS with old bootrom and bb 05.13.04. Used sowbeeze to jailbreak 5.0.1. After that I went to cydia to install ultrasnow. I added the source but ultrasnow after installation has an empty list.
    Any idea what is going on. Also another phone on 3GS I opened cydia and it upgraded ultrasnow and the same thing happen ultrasnow source list in empty. Thanks…

    Ok…this comment literally made me laugh out loud. That is funny!!!!

  • Alice

    I have exactly the same problem as you.
    Baseband 05.16.05 and willing to flash in the ipad baseband but as you said no option to do that is available in Redsnow.

    @Dave Knapp, when you say a “clean restore” do you mean doing a restore from iTunes as if we had a sim free iPhone? Because i read that this shouldn’t be done since it would upgrade the baseband to one which is (if possible) even less unlockable than the 05.16.05 baseband

    Thanks for you help

    Hello all,
    I have a store demo iphone 4 with ios 5.0.1 and firmware modem 4.11.08. The problem is that I try to jailbreak it but it gives me exploit failed after second step.

    Could you please help me?

    Any solution for this problem… I have the same issue… I have tried everything mentioned above and repeated every single step… including restarting (Jobyvettukattil), which doesn’t work at all…

  • shafiqullah esmat

    you need to search for ultrasn0w in search area of Cydia there you can find Ultrasn0w.
    Let me know.

  • shafiqullah esmat

    The Recommended version is 9.10b1. Use this version you won’t get exploit.

  • Fabrizio

    I have done the same with 9.10b3 under MAC and my iphone is jailbreaked but not sim unlocked.
    I have also ios 5.01 and FW 4.11.08.

    I will really appreciate if someone can help.

  • shafiqullah esmat

    you need to use Redsn0w 0.9.10b1 in order to jail break. Use this version flash your iPhone Baseband and you phone will start working within few minutes. But remember while jail breaking don’t put the sim into your iPhone until you jail break and installed ultrasn0w.

  • shafiqullah esmat

    You need to jail break your device using Redsn0w 9.10b1 and you can’t unlock your iPhone with 4.11.08 baseband. What you need to do is just wait.

  • Fabrizio

    Hi Shafiqullah,

    I did again the process with 9.10b1.
    Same situation, it is not simunlocked.
    In one of some procedures, I saw that they restored the iphone with the customized ipsw, should I do this or it is for GEVEY procedure?
    Many thanks for your hepl

  • vatsal

    and did restore from iTunes _the sn0wbreeze ipsw

    its working but only thing is not recognizing carrier
    i m in toronto using chatr sim

    could anyone help me out? plz

  • shafiqullah esmat

    Hi Fabirizio

    you are welcome.
    What you need to do is just wait for GEVEY Sim until it comes. But let me tell you this that those are using customized ipsw who doesn’t want to update their Baseband in iPhone 4. So if you face this problem in iPhone 3gs. You need to update its baseband i am 100% sure it is working well by unlocking your iPhone 3gs using ultrasn0w.

  • shafiqullah esmat

    Hi Vatsal

    If you want to use your iPhone 3gs with any carrier you can do it. Just follow these instruction and you are there.
    1. update your iPhone 3gs using latest version of iTunes.
    2. Jail break it with Redsn0w 9.10b1 and be care full to select both install cydia and install iPad Baseband while jail breaking your iPhone 3gs.
    3. install ultrasn0w 1.2.5 version
    4 Reboot your iPhone 3gs.

    Note: You must remove your sim while updating, jail breaking and installing ultrasn0w into your iPhone 3gs. When you done with these there steps just insert your sim and there you go.

    One more important point after installation of ultrasn0w and rebooting your iPhone just keep the WIFI turned off.

    Thank you soo much Robert!!! I have a 3GS with firmware 05.16.05 with serial number with difit nr 3-5 higher than 135. Was almost giving up changing the firmware to ipad bb after reading all the warnings from redsn0w but then when I saw your post I decided to give it a try. Works perfectly!

    Was a bit worried cause I had installed cydia first then ultrasn0w and then noticed that my firmware was not supported/recommended. Was thinking of giving up but then your post saved me :) First time for me aswell!

  • Tresser

    Im not sure if you had the same issue as me but I also had 05.16.05 and changed mine to the 06.15.00 by just clicking on change to ipad bb using redsn0w_win_0.9.10b3 and not installing cydia again. I jailbroke mine first and then installed the ipad baseband following roberts post. Check Robert B’s post.

  • Flycreep01

    To all 3GS owners with a BB of 6.15.00, and with a week/SN not higher than 35, with a network problem please follow this simple steps.

    1.back-up your device using itunes v10+. the correct firmware for your unit ( .ipsw) or just update using itunes. the latest redsnow.
    4.just to be sure turn off your wifi, 3G, cell data, and cell data network, and also remove your sim card. run redsnow > extras > select IPSW. after select, click open then ok then yes then hit back. JAILBREAK follow the instructions then put a check on (install cydia) if not yet installed in your device. then also check (install ipad baseband) even if your already in the ipad BB . then click next. cydia > changes > refresh > search for ultrasn0w 1.2.5 > install > restart.
    8.put back your simcard then call your loveones and say hi! :)

    Good luck and happy jailbreaking! ;)

    FIRMWARE 5.0.1
    BB 6.15.00
    Iphone 3GS

    Hey, I have an IPhone 3GS. I preserved my baseband with sn0wbreeze at 6.15.00 and jailbroke it with redsn0w 0.9.10b3, now using 5.0.1 with the 6.15.00 baseband. Everything is working well on tmobile. The only problem I am having is that it still acts like a tethered jailbreak. if I shut it off it gets stuck in the apple logo. I go back on redsnow, justboot it, and then it gets stuck on the pineapple logo there. If I hold the home and power button down and restart it, it came back on, I just don’t understand why this is happening. I also downloaded Corona Untether through Cydia to see if that was it, but that didn’t help.

  • Jess

    Hey, is there a way to unlock a jailbroken 3Gs with the BB at 5.16.05 without changing to iPad BB? Thanks!

  • Farouk_beg

    Do you mean that ur iphone serial number is higher then 135 and you change it to ipad BB ???

  • Anonymous

    Thanks for your reply. Not sure what’s going on. I read in another forum that if I try to change the BB to 06.15.00 from 05.16.05 someone said it will not only break the GPS but so many other things that the iphone would be nothing more than a paperweight. I’m so confused it’s crazy. Doesn’t look like anyone has any plans for an unlock for the dreaded 05.16.05 bb, I think I should just give up. Too many different stories going on.

  • Anonymous

    Thank you for the reply. I may give up. So many stories, it’s confusing. My phone is jb using latest redsn0w. Never cared about JB, just want to unlock. Someone in another forum said if you flash the BB on a 3gs, 5.0.1 05.16.00 you still can’t unlock and it will become a paperweight. So I have no clue what to believe anymore. And it looks like the hackers won’t be trying to make an unlock for this baseband.
    Thanks again!!

  • Mtawheed

    I have an iphone 3Gs
    Serial number: xx018xxxxxx
    Base band 6.15
    ios (5.0.1 or 4.1 or 4.2.1 or 4.3.3)

    I was running iOS 4.3.3 which was great, I decided to update to iOS 5.0.1. The problem I was experiencing after I updated to iOS 5.0.1 is I cannot activate my phone and my sim card cannot be detected properly (no service), but my sim works fine when I use it in a different phone.

    I was stuck in this so I jailbroke the iphone and installled ultrasnow 1.2.5, and now it is activated but no sim card – no service all the time.

    When I go back to an earlier ios (4.3.3 or 4.1) I get the same issue (no sim card – no service)

    I don’t know what is wrong..

  • shafiqullah esmat

    Hi Charudatt Dobariya.

    You need to remove your SIM while jail breaking your iPhone 3gs.
    After jail break you must install ultrasn0w from cydia. Then turn off your WIFI and put your sim in your iPhone 3gs.

    Remember: Use Redsn0w 0.9.10b1 to jail break your device.

    I just bought the iphone-unlocker pro software. I have a Canadian Telus iphone 4 with ios 5.0.1, I jailbroke my phone then it would not let me add the unltrasn0w software in Cydia. Is it possible to unlock the phone yet with that software? or will it come out later or have I have just learnt a really valuable lesson and been scammed? anyones feedback would be very much appreciated….

  • C N

    Actually the 9 means 2009 so technically it should work….yet ultrasn0w 1.2.5 isn’t working after i install it in cydia. The problem might be because I accidentally upgraded to 5.0.1 officially through apple before I jailbroke the phone. I’m going to try installing a custom ipsw for 5.0.1, and then redsn0w and ultrasn0w again. Anyone else have any luck with unlocking after having installed the official 5.0.1 update from apple?

  • Wiwin

    FOR IPHONE 3GS users:

    To unlock your iDevice, in order to use it with other network, you will need some information. Jailbreaking and flashing your BB to 6.15.00 will not work 100%, you have to keep in mind that iPhone 3gs has two model of bootrom, what they call “New Bootrom” and “Old Bootrom”. For those who have the new bootrom and who accidentally flashed your BB to 6.15.00 using redsn0w, you have risked to brick your iDevice for life! which means that your wifi, imei, iccid, bluetooth will not work and possibility to brick your phone for life. For those who have the old bootrom, you are safe to flash your BB with 6.15.00 then use Ultrasn0w to unlock your iDevice, gotta make sure that your sim card is out while you perform the flash and jailbreak process, for it can cause the “No service” issue but you have to keep in mind that this process will cause your GPS to not function. With that being said, I recommend that you search enough information before performing the jailbreak and unlock. You might want to check Snowbreeze’s guide on how to preserve your baseband to jailbreak and unlock your device, personally I prefer Snowbreeze than redsn0w, just my personal opinion.

    Some info to help you know if you have a new or old bootrom:

    From the serial number (iPhone 3GS)
    The third digit of the serial number identifies the year of manufacture (9=2009, 0=2010), while the fourth and the fifth indicate the week. The first “new bootrom” devices are from week 40 of 2009 (??940?????? or higher serials). Any iPhone made after Week 45 of 2009 (??945?????? and higher or ??0???????? serials) has the new bootrom.

  • Mlowe_12

    I did everything exactly like it said and it still didn’t work…

  • Esa Syt

    You must have updated your iPhone to stock IPSW instead of Custom IPSW to preserve your baseband. Currently, 4.11.08 cannot be unlocked. Neither will Gevey unlock your iPhone. Just wait until the Devs or Applenberry give an update.

  • Esa Syt

    Use redsn0w to flash your baseband to iPad’s 6.15.00 to use ultrasn0w. Using it alone won’t benefit anything.

  • Esa Syt

    Yes, you can.

  • Esa Syt

    I’d turn off 3G and Cellular Data under settings. Then toggle Airplane mode on and off to see if that fixes it.

  • Esa Syt

    You have to flash baseband’s 6.15.00 to use ultrasn0w. 5.16.05 isn’t supported.

  • Esa Syt


  • Esa Syt

    I would apply the jailbreak with redsn0w 0.9.10b4 over your previous version.

  • Esa Syt

    You can just install ultrasn0w and it’ll unlock for you. No need to update to iOS 5.0.1. Use a custom IPSW to preserve your baseband to keep the unlock status.

  • Esa Syt

    Thhe latest redsn0w 0.9.10b4 will flash your 3G/S baseband to 6.15.00. Sn0wbreeze as well, will do the job.

  • Esa Syt

    Try rebooting the phone as opposed to a respring.

  • Esa Syt

    4.10.01 will not work with ultrasn0w 1.2.5. No unlock will be visible, just compatability (if preserving baseband).

  • Esa Syt

    It will jailbreak (redsn0w 0.9.10b4) but it will not unlock. Nothing can unlock 4.11.08.

  • Esa Syt

    You cannot unlock baseband 4.11.08 at the moment.

  • Esa Syt

    You cannot unlock baseband 4.11.08 at the moment.

  • Esa Syt

    Use redsn0w 0.9.10b4 to jailbreak it.

  • Esa Syt

    4.11.08 cannot be unlocked. Neither will Gevey do the trick.

  • Esa Syt

    Apply redsn0w 09.9.10b4 and run ultrasn0w again. Reboot the phone, don’t just respring it.

  • Esa Syt

    Unlock does not work on baseband 4.11.08. Nothing will.

    I have a 3GS which itunes updated to 5.01. Serial Number is 79939… and Modem Firmware 06. 15.00. I think I have tried all the methods stated here to unlock the fone using redsn0w to jailbreak und ultrasn0w to unlock. However I still get *searching* instead of any unlock. Am I stupid or is it just luck if it works?

  • Dtg7202

    I have the same Searching problem

  • asills

    I am having the same problems as the two below me. I am using a 3GS running on 5.0.1 on the 6.15.00 baseband. I used redsn0w jail broke perfectly fine then unlocked it but after reinstalling ultrasn0w and rejailbreaking it, am still getting the “searching”.. Please help as my backup phone is a old slider phone which is frustrating to use after using an iPhone for so long..

  • Javier Medinas

    same as me, untethered iOS 5.0.1 baseband 6.15.00 but no service

  • antique

    if you have a new boot room you don’t need to preserve baseband because every firmware will be converted to ios 6.15 so.. although preserve your bb using snowbreeze for backup. use redsnow 9.10.b4 to jailbreak as it has some new fixes and install ultrasnow after complete jailbreak . and reboot . it will work

  • antique

    reboot it for few time and use airplane mode on and off .. it may be helpful then..

  • Digofrota1

    so this is working for iPhone 4 firmware 5.0.1 and baseband 06.15.00??
    if it is I’m gonna update it’s baseband and unlock it but I’m only updating the baseband if its working.

    If you are having the SEARCHING… issue and want it to go away, go back in to Cydia and click on Modify for Ultrasn0w and remove it. I am back at reading the SIM card.

  • DarkSerpant

    Hi but I’m on iPhone 3GS iOS 5.0.1 ultrasn0w 1.2.5 unlocked and working !!
    Here is how I did it
    All I did is restore to a fresh firmware
    Then bypassed activation with redsn0w jailbreak
    Then went into redsn0w and reflashed iPad baseband and installed ultrasn0w and

    Try it!

  • BlackDog

    Can you please add exact details please if poss?
    which fresh firmware and how?
    reflashed iPd baseband how and with what.
    sorry and thanks

  • BlackDog

    ok 3GS cracked it!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
    i mean the searching issue.
    here we go:
    1. download file iphone2, and save as an ipsw file (not zip).
    2. using itunes restore the 3GS using this same ipsw file (need to hold down the shift ket whilst pressing the restore button).
    3. download redsn0w_win_0.9.10b4 and unzip.
    5. run redsn0w and select EXTRAS then select IPSW and navigate to the same ipsw file. go back and select JAILBREAK. Then do Deactivate. follow instructions
    6. After above has finished do the same as 5 but this time at JAILBREAK select load IPAD BaseBand. follow instructions.
    7. After above has finished do same as 5 but this time at JAILBREAK select install CYDIA. follow instructions.
    8. After above finished use CYDIA to install ULTRASN0W.
    9. after above INSERT SIM

    Did the above and I now have a 3GS working unlocked on THREE.UK (WAS LOCKED TO O2)

    Good Luck

  • Stevenrayxxx

    Thank You so very much, after a few days I was about to put the phone away for a while. I found your post and on the first attempt, I know have a working phone.

  • silvr

    i have and iphone 4 i am using reds0w 0.9.10b4 but i am unable to see the “load ipad baseband” option. currently my phone has the 4.11.08 bb.

  • BlackDog

    See above…now fixed

  • ashish tanti

    I had a 3gs with 4.3.3 unlocked using ultrasnow on BB 6.15.00 which i updated to 5.0.1 using redsnow and did not preserve the baseband. Also it is a xx945 serial device. keep getting “searching” message even after installing ultrasnow. help..

  • Ryan Kingdon

    Hey, there is an easier way, restore the original through i tunes, then use red snow and choose the same ipsw but check jailbreak ipad baseband and deactivate, all at the same time, does the same trick.

  • Ryan Kingdon

    Click onto jailbreak and it will there, along with jailbreak and deactivate

  • silvr

    i clicked on jailbreak and the only options i see are: install cydia, install custom bundle, enable multitask gestures, and deactivate.

    there is no option for loading the ipad baseband.

  • BlackDog

    maybe but doesn’t work for me. redsn0w just crashes. others have same issue.

  • HeszXDopee

    Hows Your GPS After Installing iPad Baseband? You Might Already Notice The Lack In Speed On The Browser Or Maybe No Longer Having The Ability To Use Bluetooth Anymore. iPad Baseband Will Screw You Up, For Those That Already Did That, You Guys Are Now Stuck Just Like Me With Slow Browser And No Bluetooth.

    I have Iphone 3gs IOs 5.0.1 Base band 5.16.05 after Jailbreak using Redsnow 0.9.10b4!!! Ultrasn0w is Installed however No sim is Working in it.Can anyone please help me

  • BlackDog

    Interesting comment. I just tried all above. GPS working fine. BT woking fine. Safari nice and quick !?

  • Melissa

    Iphone 3gs serial 871130
    -used itune to upgrade to 5.0.1
    -jailbroke using redsnow 0.9.10b4
    -baseband updated to 5.16.05
    -unable to unlock
    Not tech savvy, Needs help with solution. Thank you

  • Wiwin

    xx939 is an old bootrom, therefore flashing the iPad baseband 6.15.00 is safe to do so, keep in mind that you will lose your gps when flashing to iPad baseband. With that being said, you can install the Ultrasnow in cydia after the jailreaking and flashing process.


  • Wiwin

    5.16.05 BB is not supported by Ultrasnow you have to flash you BB to 6.15.00 iPad baseband in order to unlock your iDevice, but be careful to first check if you have an old or new bootrom, because flashing iPad baseband on newer bootrom causes a lot of problem to your device and possibly brick your device.

  • Wiwin

    You might probably have the old bootrom that is why everything worked fine for you, though it is unfortunate for the ones with the newer bootrom because flashing iPad baseband on newer bootrom will screw up the device.

  • Wiwin

    Flashing iPad baseband to your iPhone 4 will not work, it is only design to work on older devices iPhone 3GS old bootrom and the iPhone 3G, now if you’re lucky to have baseband 01.59.00 on your device then you can unlock it with Ultrasn0w. Otherwise, there is no other way to unlock your phone, either you buy GEVEY sim to unlock your device or you go to your nearest apple store and ask them to unlock your device.
    Hope this info helps you.


  • Dmatinya

    Bought the iphone-unlock-pro software for $29.99 on the understanding that it’d unlock all previous iphones as well the iPhones 4s. I have followed all the instructions in the members area but still my iPhone 4s is Locked.

    How do I restore the iPhone4,1_5.0.1_9A405_Restore that I downloaded when the redsn0w (iUnlock-5-WIN.exe) software says it does not support this ipsw & the custom says its only for iPhone 3gs & iPhone 4?

    May you please assist me with a step-by-step explanation on how to unlock my iphone 4s, form the point where I download the “iUnlock 4s and iPad 2 5.0 -5.0.1 WIN” up to the ultrasn0w. I have found that the ultrasn0w 1.2.5 version in Cydia only supports a limited number of basebands only on the iPhone 3gs & iPhone 4 but nothing on iPhone 4s.

    May you please explain to me where i am going wrong


  • Wiwin

    XX947 is a new bootrom iPhone 3gs, now flashing iPad baseband can cause major problems to your device, I suggest not to risk flashing iPad baseband 6.15.00 unless you want to turn your device into a brick. It is better to wait for Ultrasn0w to release a new version that will support the unlock for other basebands, or you can always go to your nearest apple store and pay for the unlock.


  • Wiwin

    I guess your device is a brick by now?

  • Wiwin

    You do not tell people to flash their baseband (6.15.00) without any backup information on what to avoid and what to do, you are risking them to damage their phone. A genius like you deserves a slap on the head! (-.-)’

  • Wiwin

    It is most probably a scam, a lot of rumors speculating that unlocker softwares are just a scam, their own employees or developers writes their fake reviews on their software to get people’s attention and eventually take money from you. I personally do not trust on buying softwares online to unlock your device, these people write their program and scripts differently to unlock a device which can cause and give major damage to your device. It is preferably to use GEVEY sim as they are only the solution to unlock iPhone 4 4s and the new bootrom on 3GS.

  • Abir

    i have a iphone 3gs unlock and jailbreak it IOS 5.0.1 baseband 05.16.05 after U jailbreak U have to restore after i restore phone stuck to activation your iphone could not be activated because the activation server is temporarily unavailable Try connecting your iphone to itunes to activate it, or Try again in a few minutes PLEASE HELP ME

  • Alanhowarth901

    Im have iphone 4 ver5.0.1 baseband 04.11.08

    will this product unlock this phone

  • Wiwin

    Unfortunately Ultrasn0w only support the unlock for 01.59.00 baseband on iPhone 4, this method of flashing iPad baseband on your iPhone 4 in order to unlock will not work, it is design only to work on older devices. Use GEVEY sim or pay apple to unlock your device, since those are your two options.

  • Wiwin

    make sure you download the latest beta version of redsn0w and re-download the ipsw for the iPhone 4s… and for the unlocker software part, I think you got scammed, rumors are speculating that unclocker softwares are just a scam, people write their own review about their software to attract people.

  • guest

    Whoever you are, thank you, i just followed these steps above and i was able to jailbreak and unlock my iphone 3GS. Thanks for your help

  • Safwan Mukhtar

    I did it but on status bar its only searching and then no service I also rebooted the device…:-(

  • Rebelhon

    its not working on 3gs 5.0.1 BB 06.15.00

  • Wiwin

    What is your serial number?

  • Wiwin

    If you have the new bootrom and you’ve flashed it with iPad baseband, then you will probably have the “no service” issue, what is the serial number on your device?

  • Knightinkhaki

    Iam on a 3gs with 5.16.05 and 5.0.1.I want to jailbreak and unlock,since its a newboot rom Iam having trouble activating the phone.Iam on official carrier right now,but it wont activate.

  • Safwan Mukhtar


  • Safwan Mukhtar


  • Jess

    Mine is saying I still have to add a 3 digit code??

  • Wiwin

    Looking at your serial number, I can say that you have the new bootrom, there is a big catch when you flash iPad baseband 6.15.00 on new bootrom, you lose bluetooth, imei, iccid, once you flashed 6.15.00 you cant put it back to its original baseband. Since you’ve already risked to potentially damage your device, restore you device to factory settings in itunes, and try downloading the latest beta version of redsn0w. From there go to “extras” tab, then load your ipsw, then select “deactivate”. Once that is done, try re-jailbreak your device and make sure your sim card is out. Install Ulrasn0w, reboot your device then insert sim card, your phone now should be able to detect signal.
    Let me know.


  • Death-Dealer


    I have jailbroken phones earlier.. but these time i am clueless abour whats happening.. i falshed my iphone 3gs old bootrom to 6.15 and using the latest redsnow, Did a jailbreak inserted sim card.,. it shows searching and then No service… one thing i observed i cant find mobilesubstrate.deb cydia.. hopefully this causing a problem with most of the users who has used latest redsnow… will try today and let you know what happend…fingers crosssed.

  • Juangallo64

    I used redsn0w9.10b4 to jailbreak my iphone 3gs and install ipad baseband and when i install ultrasn0w it still doesnt pick up a signal..

  • Safwan Mukhtar

    But I didnt install ipad baseband myne is already 06.15.00… shld I still try these steps???

  • Cooperme25

    is that a known fact? I have a newer bootrom, and I don’t want to screw up my GPS/Bat, but this would be the only way for me to unlock…

  • Wiwin

    Did you buy your iPhone from someone? because you should not have that BB on your device, you can try these steps, make sure you download the latest beta version of redsn0w, it fixes some of the newer bootrom flashed with iPad baseband, and I say “some”, however.


  • Wiwin

    Try Sn0wbreeze, it’ll fix your problem =)

  • Wiwin

    I had the same issue before on my old bootrom device, try restoring your device to factory settings. Download Sn0wbreeze latest version, create a custom hacktivate ipws meaning cydia will be included, then restore that custom ipws in iTunes, and install Ultrasn0w. This fixed my problem.


  • Wiwin

    Some of the device with new bootrom built in week 40 to 45, the result varies. I have an old and new bootrom iPhone 3GS, I risked to flashed iPad baseband on the newer bootrom, knowing that this is the only way I can unlock my phone, it was succesful, but from time to time my phone drains battery like crazy, could not connect to wifi, bluetooth goes wild, screen freezes, to the point I stopped using my phone. But, a friend of mine asked me to jailbreak and unlock his new bootrom device, of course knowing the risk, now got himself an unlocked iPhone with no problem at all, unlike mine. I am just waiting for redsn0w to fix this issue on newer bootrom flashed with iPad BB. You have 50-50 chance that it’ll work, so its all up to you. Cheers.

  • Wiwin

    is it an old bootrom? or new?

  • Wiwin

    As of now, there is no successful way to downgrade a baseband, to put it in other words: its impossible to downgrade a baseband. This method can only be done by replacing your baseband chip. Musclenerd of the chronic devteam announced a downgrade for baseband 6.15.00 to fix the lost gps fix on older devices. Two years later still no release for a downgrade, because by now he probably figured that this method of flashing baseband chip is impossible, it will therefore destroy the device. Test has been conducted and results were broken devices, He is now ignoring this issue and seems not to give a F**k anymore.

    I bought my iphone 4 in Saudi Arabia and it was already unlocked when I bought it. It’s baseband is 04.10.01. Do you think I can update my iphone to the latest iOS? I’m just afraid it will lock itself. And I don’t think ultrasnow will ba able to unlock it for me.
    My brother bought his in an Apple Store, also unlocked. He updated his with iOS 5 and did not lock.
    Please help. Thanks!

  • R0ckSurf

    create a custom ipsw with sn0wbreeze and jailbreak it with redsn0w with install cydia, ipad baseband & deactivate and after install ultrasn0w it will work.

  • R0ckSurf

    First, you must have Sn0wbreeze for creating a custom firmware. Start Sn0wbreeze and select Baseband preservation mode. So create a custom firmware and restore in DFU mode with iTunes with firmaware normally created on the desktop.
    Then open redsn0w and go to extras, select and select your ipsw firmware official. Click on back then jailbreak. Put yourself in DFU mode and select install cydia, install ipad baseband and deactivate. After reboot, you should have “No SIM” in the place of search or indisp Network.
    It only remains for you to configure your iPhone and then insert your SIM.
    Finally, you must install ultrasn0w via Cydia. Reboot and the work is finished.

  • bryan

    ur instruction clear and i had unlock it !

  • Wiwin

    If your iPhone 4 is factory unlocked, then you do not need ultrasnow to unlock your device, it should work on any network and therefore you should be able to jailbreak your device.

  • Wiwin

    Use Sn0wbreeze and it would solve your issue.

  • Wiwin

    You will get charge, this process only provides you detail and step to unlock your device, not to free you from data charge on your sim network.

  • Wiwin

    Refer to what R0ckSurf posted, how to use Sn0wbreeze, because I have used Sn0wbreeze as well and it solved the same issue as you are having.

    okay it worked for me on my 3GS with baseband but the only problem is, is that the service keeps dropping whenever it wants to. Usually where there is meant to be signal the bars just go and then come back, is there a way to resolve this? help is much appreciated :) thanks

    When you installed ultrasn0w was your sim card already in your iPhone?

    I have an Iphone 3GS. Its modem firmware is 06.15.00. Serial is 88939. I’m currently running IOS 4.1. I would like to update to 5.0.1 but I’m not for sure if that if I do this that my phone will still work. My phone was bought off of Ebay last year by my fiance. It is unlocked/jailbroken but not factory. If I do this, will it still work on the new IOS. Also if save my baseband and the IOS I’m currently on, can I restore to that if this does not work for me?

I try downloading ultrasn0w to unlock my iphone 3GS with 5.0.1 IOS, 6.15.00 baseband, but on that last screenshot you posted, i can’t see the description of ultrasn0w at all and it doesn’t work for me. Like i can hit install and confirm and something happens but the whole bottom of the screen is blank. All i can see on my screen when i do that is that part on that last screen shot that says “Search Details Install”. That’s all i can see, idk what to do from there.

  • guiri

    Please help! I have an iPhone 3GS jailbroken and unlocked with a 6.15 ipad baseboard and an older bootrom. This morning I did a custom restore from 4.3.3 to 5.0.1, after some struggle I was able to get the phone to the setup page. Went through the instructions and added ultrasn0w 1.2.5 in cydia. I pressed “restart springboard” and my sim card was recognised. 3 minutes later my iPhone was dead. I am unable to reboot, tethered or otherwise and cannot enter DFU mode. The phone doesnt react to anything, doesn´t turn on or charge….no apple logo…nada.

    Anyone have any ideas or help they can offer?? Thanks

  • guiri

    I just read somewhere that I was supposed to take out the sim card before installing ultrasnow…was that my problem? how can I undo this?

  • Wiwin

    My suggestion is try using other network’s micro sim card, if it gets a network signal then it is definitely a factory unlocked device.


  • Wiwin

    To make things clear before proceeding to a solution, what is the serial number of your device?

  • Wiwin

    This should not happen if you are certain that you have an old bootrom.

  • Luis Torres

    I tried jailbreaking my old 3gs for my daughter, I managed to jailbreak it and tried to unlock it. I inserted the sim card back in after I followed the instructions and it said the sim was locked? so what do I do now?

  • Icabau

    I have an iPhone 3GS with IOS 5.0.1 and Baseband 06.15.00 (locked by Vodafone Spain). I tried to use it with an O2 sim and I can’t. I did jailbreak with Redsn0w, Pwnage tools, and tried with ultrasn0w and SAM… But it doesn’t find carrier, it’s still searching…
    What happens? What can I do.

  • Mindy Gonzalez

    i have a 3gs , and wanting to update to 5.0.1, but im gonna need a ipad baseband, i know about the warnings not to flash baseband if you haVE NEW bootrom, i have checked my bootrom from the usb settings, and it says i have the old one, but my question is that my 3gs is what i believe to be a refurbished phone, serial number starts with 5k0144 i have read that the 5k stands for refurbished but do the following numbers stand for the month and week of making? if you can help i would much apprieciate it. i just dont want to brick a perfectly good phone.

    3. download redsn0w_win_0.9.10b4 and unzip.
    4. REMOVE SIM5. run redsn0w and select EXTRAS then select IPSW and navigate to the same ipsw file. go back and select JAILBREAK. Then do Deactivate. follow instructions
    6. After above has finished do the same as
    5 but this time at JAILBREAK select load IPAD BaseBand. follow instructions.
    7. After above has finished do same as 5 but this time at JAILBREAK select install CYDIA. follow instructions.
    8. After above finished

    I followed the above steps and upgraded my ios to 5.0.1 (iphone 3gs) bb 6.15. Jailbroke and installed ultrasnow. Now it won’t recognize any sim card. I have T-Mobile and it says searching then finally goes to no service. Tried my son’s ATT sim card and it stayed on searching. I have turned 3g services off, data off, location services off. I have tried turning the phone off and on, reinserting the sim card, etc. Nothing appears to work. Thanks for any help.

    My wife & I have old iphone 3G (no ‘s’) phones, still on ios 3.1.3, that have been jailbroken with Cidia. We use them with prepaid ‘gophone’ type plans, with no data plans, and do not use any non-itunes apps on the phones. My wife is having problems with many of her itunes apps failing to work. Will the new jailbreak for ios5 work on these old 3G phones? I only see ’3GS’ mentioned in the list of phones that can be jailbroken with the new fix. Or, do I even need to worry about it? Can I update to ios5 & still use the phones on my prepaid AT&T accounts?



  • Tips

    What about baseband 03.10.01? Is there any way that I can get that unlocked besides the Gevey SIM?

  • Javier Medina

    yes it works, you see 3gs cause are the most common iPhones, bus with normal iphone3 works perfecty, and the other reason its that 3gs gives more difficulties about unlocking normal 3 its easier to jailbreak and doesn’t come lock for an specific company. 3gs sometimes came lock for at&t or another the 3 came generally unlocked for all companies.

    Does the reboot need to be tethered? any other suggestions?

    do NOT update your baseband to ipad 2 or you will lose your gps capapbility and your phone signal will diminish as will your wi-fi signal…

    Run redsn0w without the Install Cydia option checked first, just the iPad baseband update. Then you’ll need to restore and run redsn0w again with just Cydia checked. I had the same exact problem for days.

  • Justin Trueman

    change your APN settings to the new carrier that you are using after the unlock
    i.e. if you were on vodafone and are now on o2 you’ll need to put o2 apn settings instead of vodafone ones. they’re found under settings/network/cellulardatanetwork
    hope this helps

I know want to update this jailbreak using the latest JB software but am not sure which guide to follow because all the guides mention that using custom fw to preserve BB and unlock will only offer a tethered jailbreak. doesw anyone have any idea how to rejailbreak my iphone 4 and preserve my BB, with an untethered JB.

I think the iPhone 3G only upgrades to 4.2.1, so iOS 5 is not an option (I know there are ways to force-install it, but I wouldn’t recommend that because it will run kinda slow. As a matter of fact, I feel iOS 5.0.1 runs slow on my 3GS.)

    I have this iPhone 3GS (originally from AT&T USA) that already had iPad baseband 06.15.00 (and was already jailbroken, unblocked with ultrasn0w, and working perfectly fine on Claro’s network in Panama), so I just created a custom ipsw to preserve it and then upgraded it from 4.3 – but instead of upgrading to 5.0.1 it accidentally went all the way up to 5.1
    I downgraded to 5.0.1 via alt+restore on iTunes and luckily it allowed me to do so. Now is where the problem comes: it is on 5.0.1 with an ultrasn0w-compatible baseband (06.15.00), but when I install ultrasn0w 1.2.5 i keep getting the same “no signal” message after it takes quite a while on “searching” mode. This happens even after several airplane mode>reboot attempts. It is the old one (week 35) and I’m running out of ideas. Any help? It would be greatly appreciated.

    With the Iphone 3gs only, I’ve screwed up and updated to iOS 5.1. I had a lot of issues and it took a little while but it works now just fine as it did before the upgrade. All I did was once i had the phone back in iOS 5.0.1, I went back into redsn0w 0.9.10b6 and I re-jailbroke it and instead of just clicking the Cydia, I also clicked the Ipad BB. I let it cycle through the jailbreak and as soon as it came back on it had the signal that was lost. Just reflash with both of those during the jailbreak and it should work just fine. I hope this helps out some people that made the same mistake that I did. If you’ve upgraded already and need help going back down I’ve already done my trial and error with it so hit me up. . if you need the help just let me know. I think i’ve got it figured out.

    Hi Mb,
    I recently relocated to Sth- Korea and have a canadian telus ifone 3gs. I get the impression by your posting an individual can’t be on 5.1 for this process to work successfully, is that correct? Is there a way to downgrade back?
    I only got into the jail breaking recently when it was suggested as a way to keep my existing phone and use it in Asia. Any direction would be awesome.

    just back from holiday and disaster strikes… can’t lose all these photos, please help.

    2 year old iphone 3gs 3.1.3 jailbroken (many moons ago). suddenly entered recovery mode – then dfu (apple logo). managed to exit back to recovery mode briefly before stupidly running pwned dfu with snowbreeze 2.9.3

    is there any hope to get it back to recovery mode (or normal dfu) to try fix recovery/recboot/tinyumbrella? or upgrade without losing everything since last backup?

    any suggestions greatly appreciated.
