1. An introduction to SHSH
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 signing of older firmware after a certain period as the latest one is released. For example, the Apple released iOS 7, and then stopped the signing of iOS 6.1.3. '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 using 3uTools 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 blobs to pass the Apple’s authentication server.
