How to Downgrade iOS 6 to iOS 5.1.1, 5.1, 5.0.1 on iPhone 4 with Redsn0w 0.9.15b2


The latest version of Redsn0w 0.9.15b2 has got many perks for the jailbreak community. Not just iOS 6 tethered jailbreak but you can now easily downgrade from iOS 6 to iOS 5.x or any iOS 5.x to any iOS 5.x. Please keep in mind that this is only possible if you have SHSH blobs saved for your device via TinyUmbrella or on Cydia. Also this will not work if you have ever updated via OTA to iOS 5.x or iOS 6.0.

Also the process of restoring to older firmware is much more simplified, no more complicated 15-step how-to’s with stitching, iTunes errors, and “hosts file” concerns. The iOS 6 downgrade is applicable for all A4 devices i.e iPhone 4, iPod Touch 4G and iPhone 3GS. The only exception here is iPad 2, the only A5 device which can be downgraded to iOS 5 from iOS 6, however the SHSH blobs condition still hold true for this too. But along with ioS 5.x SHSH blobs you will also need iOS 4.x blobs too.

We have tried and tested iPhone 4 downgrade from iOS 6.0 to iOS 5.0.1 and iOS 5.1.1 and both time it worked perfectly. Though the process is not one click but Redsn0w 0.9.15b2 will guide you through out the process.

Here is our step by step guide on how to downgrade iOS 6 to iOS 5.0.1, 5.1.1 on iPhone 4. Please keep in mind you can only downgrade if you have SHSH blobs saved for your iPhone using TinyUmbrella or Cydia.

Yes it works for iPad 2 too, but before that I would like to know do you have SHSH blobs for iOS 5.x and iOS 4.x for your iPad 2 ?? if yes then only you will be able to downgrade.

Dont click on NO when Redsn0w asks for prevent Baseband Update. You must select Yes as your baseband is already updated to latest one when you updated to iOS 6.0
