In the past week, the Dev Team has released a major upgrade to its Redsn0w jailbreak utility with iOS 5.1.1 untether support, and that includes using the Rocky Racoon 5.1.1 untether, some of the updates includes the version Redsn0w 0.9.12b1, PwnageTool 5.1.1, cinject 0.5.4 and Ultrasn0w 1.2.7.
With the introduction of Redsn0w 0.9.12b1 there were two different ways to install the Rocky Racoon jailbreak on A4 chip devices and earlier ones, that allowed users to backup and restore method, as we can have in the Absinthe and Cinject, or it could user the Limera1n-based ramdisk approach which doesn’t required a lengthy backup process (No DFU mode used).
This latest update from the iPhone Dev Team covering the Redsn0w 0.9.12b2 that comes with a new option for SAM unlockers, that allowed users to restore their activation tickets, and other improvements with Limera1n-able devices.
Today’s updtae from the iPhone Dev Team was a smaller release. Redsn0w 0.9.12b2 just surfaced on the official website, featuring a new rocky-racoon injection option and an iBooks bug fix and more, you can check the below change log:
“ Starting with version 0.9.12b2, redsn0w will now explicitly ask users with limera1n-able devices whether they want to inject rocky-racoon using the DFU ramdisk method, ro the backup/restore method (the ramdisk method is better for those with lots of media on their device that would create very large backups, and it’s required for those with unactivated iPhones). If you’ll always want to use limera1n, you can select that in the Preferences pane. It also fixes an iBooks issue an old-bootrom 3GS iPhones, and provides more useful error messages when things go wrong.”
With this updated 0.9.12b2 version of Redsn0w you can get the improved access to the coice of many features. While the option to choose an approach wasn’t an accessible in Redsn0w’s GUI itself and choosing installation method depends on your device was in DFU mode or not before being hooked up to the jailbreak tool.
* If your iOS device is in DFU mode, then Redsn0w will use the Limera1n eamdisk install and if not it uses the backup and restore method which is based on injection with Rocky-Racoon 5.1.1.
So that older method must be needed to replace while it requires users to know which type of jailbreak they want before they even boot up Redsn0w. RTFM might be a good option, but it explicit options are good GUI.
We can recommend the second option, backing up and restoring which is more reliable and requires less hassle to set it up and if are havinf lots of media on your devices, then it could take a while and use your computer’s hard drive space.
Older and lengthy option, if you having lots of photos, videos and music on your device, using the Limera1n method with Redsn0w v0.9.12b2 is better. However the ramdisk method doesn’t support devices sporting A5 chips like, iPhone 4S or the second-gen iPad or 3rd-generation tablets, and are not compatible with the Limera1n exploit though.
If you have already jailbroken your devices, there is no need to run this or re-jailbreak using this newer version. But pre A5 device users needing to restore and re-jailbreak will find this update a lot easier and faster.
If you’re one of the folks experiencing the iBooks issue on your 3GS, using Redsn0w’s latest version 0.9.12b2 will get rid of it. Enjoy!
