Hi Guys, need a bit of help... I have a 4S running 5.1.1 jailbroken. I need to restore it back to stock but keep the original firmware, is there an easy way to do it? Thanks.
If you are just doing this to sell it, I recommend using iLEX Rat. Will wipe everything off the phone except original firmware and Cydia - but it cannot fix corrupted files (in case that is why you want to restore)
