Redsn0w Will Soon Allow You to Downgrade Your iPhone 4S, iPad 2, New iPad

We’ve some great news for iPhone 4SiPad 2 and new iPad users who may have accidentally upgraded their jailbroken iOS devices to iOS 5.1 or iOS 5.1.1.

MuscleNerd of the iPhone Dev team has just revealed that they plan to release a new version of Redsn0w that will allow users to downgrade to iOS 5.0.1.

MuscleNerd has just tweeted:

Upcoming redsn0w supports restoring, including iPad2/3 and 4S downgrades (with blobs) ..also stitches on the fly 🙂

We have been eagerly waiting for this after iH8sn0w revealed that he had managed to successfully downgrade his iPad 2 to iOS 5.0.1 from iOS 5.1. But he hasn’t been able to release it, as his method had legal issues. MuscleNerd has revealed that their downgrade method is legal.

It is currently possible to downgrade iPhone 3GS, iPhone 4, iPad 1, iPod touch 4G and iPod touch 3G from iOS 5.1 to iOS 5.0.1 using the SHSH blobs saved using TinyUmbrella.

It means that iPhone 4S, iPad 2 and iPad 3, which are powered by A5 chip and the new iPad, which is powered by Apple’s A5X chip can be downgraded to the previous firmware versions as well with upcoming version of Redns0w.

Users will only be able to downgrade if they’ve save SHSH blobs for the previous version either using TinyUmbrella or they had jailbroken their iOS device and launched Cydia as it also caches the SHSH blobs.

Downgrading to iOS 5.0.1 will allow users to perform the untethered jailbreak using Absinthe jailbreak. Unfortunately, users who have recently purchased their iOS device that come pre-installed with iOS 5.1 won’t be able to downgrade as personalized SHSH blobs is required for the downgrade process.

Meanwhile, if you haven’t saved the SHSH blobs, then we would strongly recommend you to do as soon as possible. You can check out this post for more details on how to save SHSH blobs using TinyUmbrella.
