Redsn0w, PwnageTool With iOS 5.1.1 Untethered Jailbreak Support & Ultrasn0w For iOS 5.1.1 Released [Updated]

Jailbreak iPod Touch On iOS 4.2.1 Redsn0w

iPhone Dev team has just released a new version of Redsn0w and PwnageTool, which includes Rocky Racoon and untethered iOS 5.1.1 jailbreak developed by pod2g and planetbeing that was used in Absinthe 2.0.x jailbreak.

If you were having problems jailbreaking your iOS device with Absinthe 2.0.x then you could try again using Redsn0w 0.9.12b1.

If you’ve already jailbroken your iOS device using Absinthe 2.0.x, iPhone Dev team’s CLI tool or the Rocky Racoon 5.1.1 Untether, then you don’t need to use Redsn0w or PwnageTool.

iPhone Dev team have provided the following information about Redsn0w 0.9.12b1 on their blog:

redsn0w allows owners of A4+earlier devices to install rocky-racoon two different ways:

  • backup/restore method similar to Absinthe and cinject
  • its traditional limera1n-based ramdisk install.  If you have a lot of media on your A4 device (music, movies, TV shows, etc), then the ramdisk method is preferrred because it avoids any possibility of later problems related to syncing to iCloud (including Photo Stream and Music Match).  The ramdisk method is not available for A5 devices or later because limera1n can’t be used.  If you’d like to use redsn0w’s ramdisk method, just be sure to put the A4 device in DFU or Recovery mode before starting redsn0w (otherwise it will immediately start to use the backup/restore method).
iPhone Dev team has also added support for the SAM unlock, which allows you to add the SAM tickets that you might have saved as part of your initial ramdisk jailbreak of iPhone 4 or earlier. Alternatively, it allows you can upload your SAM tickets to any device after its been jailbroken.
redsn0w accepts either the individual SAM activation ticket plist file, or the entire zip file created by redsn0w’s “Backup” button. 
Redsn0w 0.9.12b1 now allows users to jailbreak their iOS device on iOS 5.1.1 all the way back to iOS 4.1.

PwnageTool 5.1.1 allows users who depend on Ultrasn0w to unlock their iPhone, to create and update iPhone with custom pre-jailbroken iOS 5.1.1 firmware file to preserve the baseband. PwnageTool is available only for Mac users. iH8sn0w had released Sn0wbreeze 2.9.5 for Windows users.

Dev team has also released an updated version of Ultrasn0w (v1.2.7), which now supports iOS 5.1.1 that can be installed after preserving baseband with PwnageTool or Sn0wbreeze.

iPhone Dev team have provided the following information about PwnageTool and Ultrasn0w:

PwnageTool also avoids any possible sync issues, but again it applies only to A4+earlier devices.  If you unlock your iPhone with ultrasn0w or a commercial method, you must use PwnageTool to avoid updating your baseband otherwise you’ll lose the unlock.  PwnageTool will also jailbreak+untether the AppleTV2,1 5.0_2B206f (unless you customize the IPSW further, you’ll have just basic SSH access to the device).
iPhone Dev team had included PwnageTool functionality into Redsn0w last year so it’s not clear why they’ve again released PwnageTool as a standalone tool to create custom iOS 5.1.1 firmware file.

    cool, works

  • Andy

    Wonder how many user out there had preserved baseband and use ultrasn0w to unlock their phone.

    • Ryan

      Me, on my old iPhone 4, but I have the 4S too

  • rrug

    Just tried the jailbreak on Iphone 4 5.1.1. In DFU mode and in ITUNEs mode both failed. Got a error 2000 during the backup process. This was on a vista machine and I ran it as administrator. Any advice?

    • nabariba


    • lexluthor

      I just go the same error, but simply ran redsn0w again and it worked.

      BTW, as far as I know redsn0w 0.9.12b1 doesn’t require putting the device in DFU mode to jailbreak, as it is based on the current Absinthe/Rocky Racoon method. I’ve jailbroken two 3GS phones and one iPad 3 and none of them required it. Good luck!

      • Miro

        same here, error 2000…I tried it many times…any advice?

        • Uriel

          Hoe all u need to do is restore you device with iTunes….(make sure you backup first)

      • Jasn

        I’ve got a 3GS running 5.0, if I create a custom IPSW with redshow/pwnage will I keep the same baseband and allow me to unlock?

        • rrug

          I had to restore the phone and then run Redsnow. Jailbreak took seconds and I am now reloading my apps!

  • Frank

    I restored my phone to factory condition then jailbrake worked the sync with my iTunes all working now

      No, you can’t as iOS 7 is not compatible with iPod touch 2G.
