Jailbreak iOS 5.1 on iPhone, iPad, iPod touch Using Redsn0w [Video Tutorial]

Today Apple has been released iOS 5.1 and now the dev-team releases the new jailbreak for iOS 5.1.

Already be aware that this new jailbreak is tethered it means you will need to connect your device to a computer to boot tethered each time it is switched off for whatever reason.

  • As already mentioned, this jailbreak does not work on the iPad 2 or iPhone 4S.
  • If you unlock with GEVEY or Ultrasn0w, DO NOT update to the stock iOS 5.1 firmware. Skip to the latter part of this guide for more info.
  • You will be booting tethered quite a bit, so if you don’t think you can deal with constantly connecting and rebooting, wait for an untethered or downgrade to iOS 5.0.1/4.x.
 How to Jailbreak the iOS 5.1 using Redsn0w.

Step 1: Download the latest version of iTunes 10.6.

Step 2: Open iTunes and backup your device.

Step 3: Upgrade your devices with new iOS 5.1.

Step 4: Download the Redsn0w 0.9.10b6 for Mac and Windows.

Step 5: Start Redsn0w then click on 'Jailbreak' then on 'Install Cydia' and then put the device into DFU mode.

Step 6: Now we move on to the process where you will need to repeat every time your device is switched off. This is called tethered boot. Launch Redsn0w, select "Extras", then"Just Boot" in order to boot your device tethered.

Booting Semi-Tethered (Optional)

The "SemiTether" patch may work through to 5.1. It’s a cross between tethered and untethered – allowing you to boot your device without a computer, but the available features are somewhat limited, so you’ll need to boot tethered through Redsn0w in order to enjoy a fully-functional break. It’s free, and available over at the BigBoss repo: http://thebigboss.org/semitether.

Note To Unlockers:

If you use the GEVEY SIM interposer or Ultrasn0w to unlock your iPhone, you will need to create a   custom .iPSW, in order to preserve your baseband.

In Redsn0w, select "Extras", then "Custom IPSW", locate your iOS 5.1 file, and let Redsn0w work its magic.

Then enter pwned DFU mode (Extras > Pwned DFU) and restore to your custom firmware via iTunes.
After that, you’ll be able to unlock with GEVEY or Ultrasn0w (when it is available).

Hope it's Helpfull to You!!
