how to backup SHSH blobs and upload the local SHSH blobs. SHSH is the key to restoring, downgrading and upgrading iOS devices. The iPhone 4 with SHSH file backups can be downgraded to any compatible iOS version using 3uTools.
What is SHSH? SHSH is short for Signature HaSH blobs. SHSH is a certificate which can be used to verify the legitimacy of restoring iOS firmware via iTunes. During the processes of upgrading and restoring the iOS firmware versions, iTunes sends the device’s ECID to the Apple’s authentication server, and applies for the SHSH upgrading/restoring this firmware version; and then the Apple will send a SHSH file in relation to the ECID to iTunes via Apple’s authentication server, so that the iTunes can continue the particular iOS firmware upgrading/restoring successfully. Let’s cite an example: SHSH is a coded key, and you need the particular SHSH file to get the access of flashing the firmware version.
What can we do with SHSH? In general the Apple will stop the older firmware signing after a particular period as the latest one is released. For example, the Apple released iOS 7, and then stopped iOS 6.1.3 signing. Signing closed means that Apple will not allow the particular iOS restoring. But you can upgrade or downgrade your iPhone 4 to any compatible iOS version if your iPhone 4 has SHSH backups.
Why I need to backup SHSH? If you want to restore your iOS device to a particular firmware version and its signing has been stopped by Apple, you need the SHSH file backup to pass the Apple’s authentication server. At present the downgrading tool can support the following devices: iPhone 4, iPhone 3GS, iPhone 3G, iTouch4, iTouch 3 and iPad 1.
