The Dev Workforce has simply redsn0w 0.9.6 RC9 on hand to jailbreak iOS 4.3.1 iOS untethered. Redsn0w 0.9.6 is appropriate with Home windows and Mac, PwnageTool four.three is for its meant completely for Mac OS customers.
The flaw used for this jailbreak is the German i0n1c, thanks to him. The process is reasonably totally different in comparison with Limera1n/Greenpois0n. As standard, we’ll present precise tutorials on each Home windows and Mac.
The 4.3.1 untether exploit comes courtesy of Stefan Esser (@i0n1c on twitter), a security researcher based in Germany. Stefan has a long history of vulnerability research, and ironically his first contribution to the iPhone jailbreak community was improved security — last year he beat Apple to the punch and implemented ASLR for jailbroken iPhones with his “antid0te” framework. We’re happy to see that Stefan then turned his iPhone attention over to an untethered jailbreak exploit!
Supported devices are the iPhone 4, iPhone 3GS, iPod touch 4G, iPod touch 3G, iPad 1 and Apple TV 2. The iPad 2 is not supported as of yet.
Here’s how to-do it:
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 4: Now select “Install Cydia” and click “Next”. Optionally (if available), you can also select any other option you like.
Step 5: Now make sure your device is both OFF and PLUGGED IN to the computer before you click “Next”.
At this stage you will be presented with a screen where you will be guided on how to enter DFU mode. Quickly hold “Power” button and then while holding the “Power” button, you will now have to hold “Home” button too. Now after few seconds release “Power” button but keep holding “Home” button until installation begins.
Step 6: Sit back and enjoy while Redsn0w does 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.
IMPORTANT: Ultrasn0w customers don’t replace but! The iPhone Dev-Staff nonetheless must unencumber an replace to ultrasn0w for the four.three.1 firmware.
We want to first unencumber an replace to ultrasn0w that fixes some incompatibilities when FW four.three.1 is used on the older basebands supported by using ultrasn0w. And take into account that after we do repair ultrasn0w for four.three.1 (we’ll announce it right here and on twitter), it’s important to best get there by way of a customized IPSW from PwnageTool, Sn0wbreeze or xpwn! Don’t ever attempt to fix or replace to a inventory IPSW, otherwise you’ll lose the jailbreak!
