TinyUmbrella – Restore device iOS version

August 20, 2011 § Leave a comment

Apple warns that you can’t restore back to previous iOS version if you upgrade to iOS 5 on your developer device. Why? 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.

TinyUmbrella is a tool you can use to restore device iOS. TinyUmbrella which does not require you to be jailbroken. TinyUmbrella sends the SHSH request through Cydia’s servers which turn around and request the SHSH from apple. This results in your SHSH being saved on Cydia and then also locally on your home computer.
