This untethered jailbreak for iOS 4.3.1 is based on an exploit found by iPhone security expert and hacker Stefan Esser, who demoed it last week before handing it over to the Dev-Team.
iOS 4.3.1 was originally jailbroken last week using PwnageTool bundles (on Mac) and Sn0wbreeze (on Windows) but was a tethered boot.
Now with this new version of Redsn0w and PwnageTool, you can jailbreak on the above mentioned devices, fully untethered on iOS 4.3.1.
- Download iOS 4.3.1 for iPhone 4, 3GS, 3G, iPad, iPod touch
- Download Redsn0w 0.9.6RC9 for Windows
- Download Redsn0w 0.9.6RC9 for Mac
- Download iTunes 10.2.1 for Windows or Mac
NOTE: Those of you who rely on a carrier unlock MUST STAY AWAY from Redsn0w and stock iOS 4.3.1 firmware. Use PwnageTool instead.
Step 1: Download iOS 4.3.1 for your version of iOS device.
Step 2: Update/Restore to iOS 4.3.1 firmware using the IPSW file you just downloaded via iTunes 10.2.1.
Step 3: Start Redsn0w and point it to the official iOS 4.3.1 firmware file.
Step 5: Now make sure your device is both OFF and PLUGGED IN to the computer before you click “Next”.
Follow the instructions to enter DFU mode
Step 6: Now, Redsn0w will do the rest for you. Once done, your iPhone, iPad or iPod touch will restart automatically and you will find it fully jailbroken (untethered) on the latest iOS 4.3.1 firmware.
