Hate iPhone 4 / 4S iOS 6, downgrade to 5.1.1
If you have already upgraded your iPhone 4 or iPhone 4S with Apple’s latest iOS software, iOS 6, but don’t really like it and would like to revert back to iOS 5.1.1 for whatever reason, you can do so as long as you have the iOS 5.1.1 SHSH blobs. Unlike the iOS 6 beat period, you do require your iOS 5.1.1 SHSH blobs saved for your smartphone because Apple has now stopped signing iOS 5.1.1.
So if you are one of the iPhone faithful that really wishes to downgrade to iOS 5.1.1, the guys over at iDownload Blog have come up with a video tutorial on just how to downgrade your iPhone 4 or iPhone 4s to iOS 5.1.1, and of course we have that video footage for your viewing consideration below.
In order to downgrade to iOS 5.1.1 you will require the latest version of Redsn0w, and they use the SHSH stitching feature to combine the iOS 5.1.1 IPSW file with the corresponding SHSH blob, and although if might sound a tad confusing, it is very easy as long as you follow carefully.
Firstly download Redsn0w 0.9.14b2, and the 5.1.1 IPSW file, you can do this by hitting up the guys website, then locate your saved SHSH blob and place it in the same folder as the 5.1.1 IPSW file. Next put your iPhone running iOS 6 into DFU mode, and then open Redsn0w and then click Extras> SHSH blobs> Stitch.
Next you click IPSW and choose the iOS 5.1.1 IPSW file for your handset, are stored on Cydia, click Cydia under the blobs section, or if your blobs are stored locally click Local and choose the SHSH blob for iOS 5.1.1 for your handset. Once you have selected both the blob and IPSW Redsn0w will then stitch them together to create an encompassing firmware file, and you will be able to use this firmware to downgrade.
In Redsn0w go back two pages, and click Pwned DFU, which will place it in Pwned DFU mode in order for iTunes to restore using the stitched firmware, if you don’t do this you will receive a 1600 error in iTunes.
Next open iTunes and it should find your device in recovery mode, and then Hold Option and click Restore and then choose the stitched firmware file, allow iTunes to completely restore your handset, you might be shown an error-1 from iTunes but do not worry. Open Redsn0w and click Extras>Recovery fix, put the handset back into DFU mode, and the Recovery fix should run.
When completed, your device should be completely restored back to iOS 5.1.1, and you are done. You can of course follow the instructions above, but you might fine it easier to follow the tutorial video below, so I’ll let you head on down and hit that play button so you can get to it…enjoy.
