The launch of the new iOS 5.1 brought along for A5 iDevice (iPad 2, iPhone 4S, new iPad) owners the nasty impossibility to go back and restore iOS 5.01 even if they backed up their SHSH blobs for that particular version of the iOS. Sadly, Apple has implemented a new restore system in iOS 5 and even though on the iDevices launched before the iPad 2 the restore process to any iOS version is possible thanks to the above mentioned SHSH, for the new gadgets this measure was deemed impossible. Until now.
iOS 5.1 Downgrade Announced
Well-known Canadian hacker iH8snow seems to have cracked the problem. In the past, he has been responsible for the production of tweaks such as Sn0wbreeze, iFaith, iReb and f0recast. He claims that the downgrade from iOS 5.1 to 5.0.1 is possible and that he actually performed on his iPad 2 thanks to a SHSH. He made the announcement it on Twitter:
“Found a loophole in Apple’s apticket system. Restored my iPad to 5.0.1 from 5.1.Works on all A5 devices.”
This problem has been giving headaches to iDevices owners who wanted a jailbreak update, as there’s no immediate way to do so. Another good reason for some to downgrade from iOS 5.1 would be the possible issue with battery. Users were left waiting for Dev-Teams to produce a jailbreak that actually worked for that particular version of the iOS. Although the A5 devices have been on the market for some time, there has not been any method available that could allow users to downgrade them.
But not anymore, from now on, users of the iPad 2, new iPad and iPhone 4S have been added to the downgrade team and will be able to perform the downgrade if and only if they have their SHSH blobs saved and stored. So far, iH8sn0w hasn’t added any more details and he probably won’t until the release is ready to meet the public. For the moment, you can jailbreak untethered the iOS 5.0.1 version on the iPhone 4S and iPad 2 using Absinthe for Windows or Mac. We will update with more news as they appear.
