downgrade your iphone4 from ios7 to ios6
Is it impossible to Downgrade from ios7 to ios6 with saved shsh blobs
yes , without this shsh blobs you cannot downgrade your iphone 4
what is shsh blob??????
SHSH blob is a small piece of data that is part of Apple's digital signature protocol for iOS restores and updates, designed to control the iOS versions that users can install on their iOS devices , generally only allowing the newest iOS version to be installable. Developers interested in iOS jailbreaking have made tools for working around this signature system in order to install jailbreakable older iOS versions that are no longer being signed by Apple.
yes without this file it is not possible to downgrade ,with this signature ios can b installed on iphone4
you should have to already saved this file with jailbreaking softwares when your iphone 4 running ios6
operating system if you havent save this file then forget about the downgrade,
you cannot use others phone shsh blob for your iphone even the same model (ie .both iphone 4)
it is unique for each and every phone
so we shall wait for the jailbreakers for some solutions
