On Friday, the prominent members of the Chronic Dev Team took to the stage at the Hack In The Box security conference in Amsterdam and ended the wait for an untethered jailbreak for majority of devices running iOS 5.1.1 by releasing Absinthe 2.0.
On the same day itself, Apple also decided to push out a revised version of the iOS 5.1.1 firmware, labeling the new build as 9B208 (the original public build of iOS 5.1.1 is labeled as 9B206). However, the newly released build was meant only for the iPhone 4 GSM.
Although the new iOS 5.1.1 9B208 build looked like a small bug fix, jailbreakers were warned to stay away from updating for the fear of losing the current jailbreak. But that threat now no longer exists as both the Chronic Dev Team and iOS hacker iH8Sn0w have come to the rescue by releasing Absinthe 2.0.2 and Sn0wbreeze 2.9.5, respectively, that add iOS 5.1.1 9B208 support for iPhone 4 GSM.
Absinthe 2.0.2 is the second update since the release of Absinthe 2.0 on Friday. After releasing Absinthe 2.0, the Chronic Dev Team also pushed out an updated version of the tool - Absinthe 2.0.1 - to fix a couple of little bugs. According to @pimskeks, Absinthe 2.0.1 is for fixing a hang that could occur in certain situations.
Thanks to the latest Absinthe update that drags the version number to 2.0.2, the owners of iPhone 4 GSM with the iOS 5.1.1 build 9B208 can also jailbreak their devices untethered. The devices supported by Absinthe 2.0.2 untethered jailbreak are - iPhone, iPhone 3G, iPhone 3GS, iPhone 4, iPhone 4S, iPad, iPad 2, the New iPad 3, iPod Touch 3/4G, iPhone 4 GSM new build 9b208.
Below are the download links for Apple's newest 9b208 build and the Absinthe 2.0.2 for Mac, Windows PC and Linux. For our step-by-step guide to know how to use Absinthe 2.0.2 to perform an untethered jailbreak on iOS 5.1.1, click here.
iH8Sn0w and Sn0wbreeze 2.9.5
Well-known iOS hacker iH8Sn0w has also announced, via Twitter, the release of the updated version of his popular jailbreak tool for Windows, Sn0wbreeze. The hacker has updated the restore based jailbreak tool to version 2.9.5 that includes key improvements like the support for the latest iOS 5.1.1 9B208 firmware build for GSM iPhone 4 and the fix for the location services issues on iPhone 3GS.
According to Redmond Pie, the location services issue has been specifically related to those 3GS users with an installed iPad baseband. The updated package will definitely serve to appease those users who insist of using Sn0wbreeze to jailbreak their A4 devices on iOS 5.1.1.
It's worth mentioning that Sn0wbreeze currently doesn't provide any support for A5 and A5X devices as there is no low level exploit in DFU or iBoot. It only supports A4 devices and below. iH8Sn0w has recommended A5(X) users to rely on pod2g's Absinthe for their untether requirements.
Below is a step-by-step guide, courtesy of Jailbreak Untethered, showing how to jailbreak iOS 5.1.1 untethered using Sn0wbreeze 2.9.5:
Step 1: Download Sn0wbreeze 2.9.5 for Windows.
Step 2: After downloading, open Sn0wbreeze 2.9.5, and click next.
Step 3: Select the Browse button and head to the iOS iPSW file.
Step 4: Now your iOS should be identified. Once this happens hit next.
Step 5: Select the Expert Mode.
Step 6: To start creating your custom firmware choose the Build IPSW option. Sn0wbreeze will decode the iOS 5.1.1 IPSW file.
Step 7: You should now be faced with a message notifying that the process is done.
Step 8: Now connect your device and follow these simple steps to enter DFU mode:
- Press and hold both the Power and Home buttons for 10 seconds continuously.
- Release the Power button and keep holding down the Home button for 10 more seconds.
- Your device should now be in DFU mode.
Step 9: Start iTunes and select your device.
Step 10: Press and hold the Shift button on the keyboard and select Restore. It will let you navigate to your custom firmware file (iPSW) which you created via Sn0wbreeze.
You are done. In a few minutes your device should be ready to use.
Meanwhile, users are highly recommended to save their iOS 5.1.1 blobs. If they ever update to any new firmware accidently and lose their jailbreak, these blobs will allow them to downgrade to the fully jailbroken iOS 5.1.1.
