How To Jailbreak iOS 5.0.1 / iOS 5 Using Ac1dSn0w (Tethered Only)

by Ahmed Omar on November 27, 2011

Wait, don’t get your hopes up! Yes, Ac1dSn0w is a new jailbreak tool but it doesn’t bring a new “jailbreak” for iPhone 4S, iPad 2 or untethers iOS 5. Ac1dsn0w jailbreak tool developed by PwnDevTeam which makes jailbreaking much easier. Below we’ll explain more.

Ac1dSn0w beta version is now available which is currently available only for Mac OS X users. It does a tethered jailbreak of iOS 5 and iOS 5.0.1 and also boots the device. This is only a taste of what the PwnDevTeam can do, currently they’re working behind the scenes on jailbreaking from another computer.

The current version of Ac1dSn0w is in an early development stage. In the future it will also be able to jailbreak remote devices. This means that you just need to install a server program on any OS (Linux, BSD, Windows) and Ac1dSn0w will jailbreak it on a client machine anywhere in the world.

Supported devices:

  • iPhone 3Gs
  • iPhone 4
  • iPod Touch 4 G
  • iPad 1

How To Jailbreak iOS 5.0.1 With Ac1dSn0w

STEP 1: Download Ac1dSn0w for Mac OS X from here.

STEP 2: Once downloaded, launch Ac1dSn0w and you’ll get the options you need as in the following screen:

STEP 3: Now connect your iOS device to your computer and turn it off.

STEP 4: Put your device in DFU mode by following the on-screen instructions by clicking “Show Assistant”:

STEP 5: Once it’s in DFU mode, hit the “Jailbreak” button in the tool.

STEP 6: You can also do a tethered boot by clicking on “Tethered Boot” button.

Waiting to see future versions of this tool.

  • If0neZman

  • NVM

    When i reading “no jailbreak for ipad2/iphone 4s”, i wanna fuck my cat

  • Fredhead

    No 4S or iPad 2?

    Just another reason to always lag one product behind the apple wave.

  • BB

    I can’t download it. It says too many users have done it already. Can anyone email it to me, please? Answer this post and I’ll give you my email address

  • L_skato2

  • Ramel Rogers

    H20 sim card will unlock iPhone, it’s a AT&T service with out the contracts

    Who cares, we want a Iphone 4S jailbreak

  • Harrow.

    Anyone know if this applies to 04.08.11 yet?

  • Hatfield Jacob

    This is a jailbreak only wait for iH8sn0w to update Ultrasn0w

  • Deshibhai

    is it wark for Windows PC

  • Anonymous

    It worked. (tested on ios5 on iphone 4) took 3 attempts.
    Its for mac osx only

  • http://www.facebook.com/zachary.cannon Zac Cannon

    tried the program twice and cydia has yet to show up.

  • Nooooooooo

    no :P

  • gewgle gewggel

    So does this mean I have to run the jailbreak twice or what? Hard reboot and go into DFU after it says “After reboot run tethered boot” and “Device has exited Recovery mode” or whatever, and then try to jailbreak it again? I keep failing to get Cydia on the device. What the hell is WRONG with it!?

    Also, does this just unlock? Or does it jailbreak too? I can’t seem to get SSH on it. (into it). Nor AFC2. What kind of failbreak is this, if it really works at all?

  • Hatfield Jacob

    Just use redsn0w ac1dsnow is not tested that very well and still in beta

  • gewgle gewggel

    Yes, but how?
    Whenever I plug in my iPhone 3GS and try to use redsn0w 0.9.9b8, it gets to the point on after uploading second stage…
    “Unrecognized build.”
    Right at this point it just immediately reboots the device (for safety measures I assume)
    And gives me a unique fingerprint. I can’t go on from here. Yes, I’m sure I’m using the 5.0 ipsw.
    I can’t even jailbreak it, nor tethered boot it from here.

    How am I supposed to do this?

  • gewgle gewggel

    This is a sad shame. There is absolutely NO jailbreak from 5.0.1 onwards…

    Goodbye, iOS hacking…. (see you again soon!)

  • Sdfghj

    cydia not showing up after “jailbreak” perhaps it didnt jailbreak my 3GS? helllllllp, cant seem to use redsn0w either or this one now ?????

  • Artydiana

    Last night I jailbroked my iPhone 4 and it worked until this morning. I noticed that Cydia, Safari and my Mail applications wont open up. So I had to restore my iPhone 4 via iTunes. I dont think I will jailbreak my iPhone 4 with Acidsnow again, I prefer with Redsnow.

  • Artydiana

    Very True. I use H20 but i need to Jailbreak my iPhone so I can MMS people.

  • hi

    wont show up in google docs? help!

  • Artydiana

    redsn0w 0.9.9b8 is the lastest redsnow ?

  • Ricciano

    choukran akhi…

  • brandon.

    See thats same with redsn0w, its semi untethered. meaning that you can still use the phone, however those apps you just described will not work, until you reboot it with acid snow again. there is no fully untethered jailbreak out

  • Noriyuki Then

    Sigh.. All you needed to do was to restart your iphone and connect it to your computer. Open Ac1dsnow and simply press Tethered boot. Also, generally you never want to do itunes direct restore. I would recommend you to avoid that at all costs.

  • JB

    My mms isn’t available now that I’ve used ac1dsn0w to jailbreak. Is there any solutions??

  • walter white

    yeah, my mms hasn’t worked since i used ac1dsn0w either. :/ there’s gotta be a simple solution to this right? someone help us :) i’m trying to debate whether i need the mms or jailbreak more… and right now, it’s jailbreak.

  • Krystallam13

    I’ve done this. but does anyone know how to unlock it now?

  • guest

    i havent found a solution either, bothers me thats its a minor thing but doesnt seem to have any fix out yet

  • Guest

    Hey I had the same problem, couldn’t send/receive MMS either. i fixed it by restoring my phone and reloading all the data. BUT the thing is if you restore your phone to a date while the MMS wasn’t working then it still wont work. so what you gotta do is restore your phone to a point before your MMS stopped working. then go ahead and jailbreak again and thats how i fixed my issue. hope its not too confusing :/
