Jailbreak iOS 5.1 iPhone, iPad, iPod touch (A4 Devices) Using Redsn0w 0.9.10b6


It was only yesterday when Apple released iOS 5.1 for all devices including the newly released “New” iPad announced in yesterday’s event. iOS 5.1 brings some new features and minor bug fixes to all iPhone, iPad and iPod touch users.
The iPhone Dev Team and BigBoss have warned jailbreakers from upgrading to iOS 5.1 because you’ll lose the untethered jailbreak made on iOS 5.0.1. However, some users updated to iOS 5.1. That’s why the iPhone Dev Team pushed a new Redsn0w update in order to allow tethered jailbreak for A4 devices using Redsn0w 0.9.10b6. Moreover, the BigBoss updated “SemiTether” jailbreak tweak to work on iOS 5.1.

Important Notes

  • This jailbreak is tethered jailbreak which means you’ll need to connect your device to computer everytime it reboots. You’ll need to do a tethered boot.
  • If you rely on unlock, don’t follow this guide. We’ll post a guide shortly on how to preserve baseband and keep the unlock.
  • The jailbreak is not meant for A5 devices, i.e. iPad 2, iPad 3 and iPhone 4S.

Jailbreak iOS 5.1 Using Redsn0w 0.9.10b6

STEP 1: Download iTunes 10.6 from here, iOS 5.1 from here and Redsn0w 0.9.10b6 [Windows/Mac].
STEP 2: Now open iTunes, back up your device and restore using the downloaded iOS 5.1.
STEP 3: Open Redsn0w, select “Jailbreak”  then “Install Cydia” and follow on-screen instructions to put your device into DFU mode.
STEP 4: Finally do a tethered boot, launch Redsn0w, select “Extras” then”Just Boot” and put your device in DFU mode to get it rebooted and working.
STEP 5: This step is optional. Now, you can get “SemiTether” tweak from Cydia, you can read everything about Semi Untethered jailbreak here. You can get the tweak for free from BigBoss repo: http://thebigboss.org/semitether.
