This question already has an answer here:
I have a device (iPhone 4S) that is running iOS 7, but I was wondering: Is it possible to restore a full backup of the same device running iOS 6.1.3.
I'm not worried about losing data from the iOS 7, but I would like to restore the device to its previous state under iOS 6.
Is this possible?
Again, to reiterate: I'm not looking for clean downgrade/install of iOS 6, I wish to restore a full back-up containing an earlier iOS. Thanks.
