Backup SHSH blobs
From wikinotes
To backup your SHSH blobs, use TinyUmbrella. This will allow you to restore a later iOS version to the version you currently backed up. This is not a backup of all of your apps and files, but rather a backup of the essential files on your iPhone pertaining to ios 5.1.1
- Download Tiny Umbrella
- Install and Run
- Connect iPhone via USB
- Click Show All SHSHs
- Click Save ALL SHSHs
The SHSH blobs are saved to: C:\Users\Will\.shsh by default
Apple will only sign SHSH blobs of THE CURRENT RELEASE OF IOS which means that you should backup your SHSH blobs as soon as possible.
