Unlock iPhone 4, 3GS iOS 5.1 Using UltraSnow Fixer

by Rania Abdin on March 13, 2012

Just last week Apple unveiled its new tablet “The New iPad” and released the new iOS “iOS 5.1″. Right after the release of iOS 5.1, chronic dev team released a tethered jailbreak for iPhone, iPad and iPod touch (A4 devices) using redsn0w. Although it’s a tethered jailbreak, many users jailbroke their devices.

Unlock 5.1 iPhone 4, 3GS

And now we have got an unlock solution for you, if you jailbroke your A4 iOS device you can get it unlocked too using ultrasn0w.
Unfortunately the ultrasn0w updated version is not released yet but we have Ultrasn0w Fixer for iOS 5.1 by developer zmaster. It’s not a public release yet but you can find it in the developer’s repo, supports only 01.59.00, 04.26.08, 05.11.07, 05.13.01, 05.12.01, 06.15.00 baseband.

Unlock iPhone 4, 3GS On iOS 5.0.1 With Ultrasn0w Fixer

NOTE: If you haven’t jailbroke your device yet and want to unlock it, make sure to jailbreak it first using our guide posted here.

STEP 1: Once jailbroken, open Cydia, click on Manage > Sources then add this repo http://repo.iparelhos.com.

STEP 2: Once the repo is added, search for ultrasn0w fixer for  5.1 and install it on your device.

STEP 3: After the installing is completed search for “Ultrasn0w”, version 1.2.5 on Cydia and install it.

STEP 4: Restart your iPhone, insert your SIM card and that’s it.

Let us know it this worked with you or not and enjoy using your unlocked device.

  • Mohamad Flefel

    thxx its working good :D

  • Moe Said

    this set up work with out Gevey Sim?????????????

  • pissedoffjailbreaker

    Unless it’s the unlock for 4.11.08 I really don’t give a fuck not do the thousands of jailbreakers promised an unlock solution in the supposed testing stages for the last 3 months.

  • Kerrigan

    Can anyone confirm if this is working on 3GS old bootrom?? Last time, someone released a fake/not working one and I had to roll back to 4.3.3.

  • T. Le

    This is so fucking stupid misleading. Why don’t you just say: this unlock doesn’t support any newer baseband on iphone 4 except 01.59.00? I don’t understand why Apple so fucking stupid. Why Apple choose to let the Chinese makes $60/gevey out of American??? Why you Apple don’t unlock the iphone and charge $50 or $60??? If you do this, the Gevey Sim will die for sure. Do the right thing and make money Apple.

  • Zeesu619shani

    Fuck off

  • Alinaim88

    It still doesn’t support the ones on iphone 4. This sucks, Everyone is desperately waiting for that unlock to come out.

  • emal bazger

    APPLE AND FUCKING APPLENBERRY you FUCKERS WASTED ALL OF MY FUCKING TIME WAIT AND WAIT AND FUCKING WAIT i’m tired of being FUCKING LOCKED AAAAAAAHHHHHHHH. ((relaxing))

  • Sharif_mloves

    When iphone 4s unlock come out? Please tell me status…..

  • Aqib

    You retared spazticated cock sucking widowed (somalian) bastard, no-one told you to update your baseband. If you had the sense you wouldn’t have this problem. Hence don’t be giving your bullshit grief to everyone else. You deserve a public beating here on Cydiahelp.

    1- A public whipping with a titanium chain with 192 20mm steel serrated bolts attached to it. Each offended member and (developer) giving you 5 whips

    2- Take a 230v mains supply /110 if your in the States etc and connect it to a 30Amp fuse, then connect the negative terminal to a 6inch probe shoved up your arse and connect the anode (positive) terminal to a spoon in your mouth. Don’t worry it will not kill you, just a pulsating shock at 30A. Then replace the fuse and continue with this therapy to sort your sexual deprivations and anger.

    3- Never return to this forum.

    Thumbs up guys :D

  • Nazusoft

    I have Iphone 3GS tried above method, does not work

  • kosova.HACK

    you need to create a ipsw with snowbreeze ….i just make a restore with costum ipsw

  • Der_ventilator

    I think this “fixers” are fake. Wait for legit ultrasnowupdate

  • emal bazger

    Hey, everyone look who’s here a person with BASEBAND 04.10.01 the band that everyone is trying to get it back, how strange…

    Look buddy you need a geveysim to unlock your phone that’s all.

  • Guest

    Hey there, re jailbreak your device using a BaseBand Preserve .. If you have not switched your baseband to 06.15.00 then do so now. Look it up on google. I have an iphone 3GS 32GB Old bootrom, and I can verify this works.. Maybe even better than it did before.. ***** Install ultrasn0w fixer before you install ultrasn0w **** .. !!!!

    iOS5.1 is great. Significantly increased my battery and nothing crashes :D good luck on your upgrades!

  • Guest

    Excelent .. Yes they must preserve baseband *DO NOT UPDATE TO IOS 5.1* without JAILBREAK PRESERVE, with iphone 4 you will get baseband 04.12.01 .. its a whole new basket of potato’s that you do not want to deal with! Keep iOS 4.0 and unlock .. or USE BASEBAND PRESERVE. Cheers!

  • Guest

    Works perfectly, iphone 3GS old bootrom .. totally supported :)

  • Guest123

    It is understandable that people get mad about there $500 ipod’s instead of iphones .. But this is also a forum .. and we all know or (should know by now) that this is where we come when we have problems .. So I, for one, am totally not surprised to find ranting’s and hate letters written all over the place. If this where a news article or possibly something that had more merit than .. unlocking an iphone 4 .. Than I would be totally with you “Aqib” .. But alas .. This is the sad part of the internet .. Where fixing and diagnosing things brings mostly stress and frustration :(
    Good luck to all. I hope I can unlock my iphone 4g soon.. Haha it is getting quite strenuous, just looking at it :P Peace!

  • Mickdddd

    Just installed the fix and it works! Got old bootrom so untethered for me! :)

  • Mickdddd

    For 3gs users. First install your custom 5.1 update (make custom via redsnow). Then push jailbreak in redsnow, only install the new ipad baseband first (uncheck jailbreak). reboot. THEN jailbreak THEN install the unlock fixer via redsnow.

    Wen jailbreaking redsnow asks you to manually select the original 5.1 firmware because youve allready ‘exploited’ the phone. You can do this by going to extra -> select ipsw.

    Worked for me (got old bootrom)

  • Reubenchenry1993

    What if your using corona for 5.0.1 for the iphone 4 what do you do

  • Mazen

  • Magnetic Gaze

    I have 04.12.01 and iphone 4g running 5.1…. I can’t seem to get this “fix” to work for me… nothing works… I can’t do anything… I can’t do anything on itunes either both upgrade and restore are grayed out…

  • Bob the Magic Moose

    I have 06.15.00 3gs and I couldn’t get it to work. Do I need to install the iPad bb? (I didn’t b/c I dont want to mess up my phone~).

  • Mel_129my

    before going thru the process do we need to preserve the baseband ?or just remove sim and follow the steps install ultrasnow fixer and update the iOS. for info my iphone 4 iOS 5 is already unlock, please let me know

  • Chandupatnala9

  • sunil

    hi Friends,

    I have a solution to unlock iphone 3GS old boot rom in ios 5.1 for baseband 6.15.00
    open redsnow with your iphone in DFU mode
    select ipsw and then go back and click on jailbreak.
    just keep tick mark on update baseband and proceed (make sure you have old boot rom 3GS phone. Phones made before 35th week of 2010 are of old boot rom. you can check this by 3rd 4th 5th digits of your serial number).
    proceed such that redsnow flashes baseband 6.15.00 .
    Install ultrasnow fixer and ultrasnow now.
    toggle b/w airplane mode and normal mode. your carrier is detected.
    Its done.

  • cameleon

    Hi,
    I have an Iphone 3GS with basedband 5.16.05. My serial number is a 2009 44wk
    I downgrade ios to 4.1 and after I use redsn0w to install Cydia and Ipad baseband.

    Now the phone is at 6.15.0 baseband with ios 4.1 installed.
    When I put my original sim card or any other one, I got No Service. It seems that the carrier is recognized is Setting->General->About.

    How can I solve that Issue

  • cameleon

    Here are the steps that I did to try to solve the issue:
    - First, I install ultraSn0w (did not solve the issue)
    - I tried reinstalling ipad BB (did not solve the issue)

  • Billiam19

    by using absinthe 2.0 instead of redsn0w

  • Anonymous

    Awesome… I have done step 3 first by install “Ultrasn0w”, version 1.2.5 from Cydia, and then step 2, “ultrasn0w fixer for 5.1″. My iphone4, ios 5.1.1. is now working again with modem firmware 01.59 .. thank you…

  • lacy

    whatever you do dont let apple updrade your 5.1.1 youll be locked out and dev boys dont have a fix yet

  • lacy

    you have to use a custom firmware and downgrade as redsnow does not support 5.1 and 5.1.1 i did the same and used redsnow to builsd a custom firmware sucks now im back to 4.1 and all my apps dont work thay only work with 4.2.1 up good luck or you could wait till the dev team

  • Dantevn

    how did you do it? i have a 3GS with 5.1.1 with 6.15.00 baseband. its jailbroken and i installed ultrasnow fixer and ultrasnow and nothing! it keeps searching. it does recognize my sim card parameters like APNs, number and carrier! but on Network (in About settings) it says Not Available! please help!

  • Anonymous

    A new ultrasn0w came out (1.2.7 I believe), you have to uninstall every previous ultrasn0w fixer and ultrasn0w and install the new one. It worked for me

  • Anonymous

    A new ultrasn0w (1.2.7) came out…you don’t need anymore the fixer. Try it if you are having trouble with the old one.

  • Caseylee

  • Caseylee

    I still cannot get this to work. I have a 3gs 5.1.1 6.15 …… Someone help please!!! I dont know what else to do!

  • Blahblah

    If you would buy an unlocked iphone in the first place you would not have any issues! If your phone is locked to a specific carrier, then you should contact your carrier. If you finished paying off your 24 months contract then the phone is yours and the carrier HAS to unlock it for you. Same reason why Apple can not unlock them, they have contracts with the carriers! Whywould they unlock a phone that is not yours? An advice: next time you want something, think before you buy, an unlocked phone with a prepaid card is for most users cheaper than a 24 months contract! ;)

    All you crybabies: get some cheese with that whine.

    All the developers: crack on guys!!!

  • Blahblah

    Always preserve baseband if you can!
