Apple released iOS 7 and later iOS 7.0.2 to the public along with the release of iPhone 5S and iPhone 5C. Developer NotCom has released an update for TinyUmbrella that supports saving the iOS 7.0.2 support SHSH blobs of A4 devices which includes iPhone 4, iPhone 3GS, and iPod Touch 4. Go through the guide to save SHSH blobs using TinyUmbrella. As per official blog – I’ve updated TU for iOS. TinyUmbrella backs up your iOS firmware SHSH blobs and can restore them to downgrade your device to an older working firmware, proving to be a potential lifesaver whenever an iOS jailbreak.
Q: What is TinyUmbrella?
A: It does two things:
- Requests SHSH signatures for firmware restores
- Plays back those signatures enabling iTunes to continue the restore
Q: What is an SHSH?
A: An SHSH is a secure signature hash. Basically its a unique key. (To avoid a lengthy discussion).
Q: Why do I need SHSHs?
A: Apple only allows you to restore to the firmwares they ‘sign’. This ‘signing’ only lasts for a limited time. Once they stop ‘signing’ the SHSHs for a firmware, there is no way to restore that firmware ever again.
