Back Up your SHSH Blobs Before It’s Too Late

I don’t exactly understand the concept behind backing up your devices SHSH Blobs, but apparently it allows you to restore from 4.1, for example, back down to 4.0. If the SHSH Blobs aren’t backed up, you’re pretty much out of luck as far as I know.

That being said, MuscleNerd posted the following on Twitter:

The 4.0 window for 3GS, ipt3G, + iPhone4 SHSH blobs is closing soon! Backup your blobs using http://is.gd/dskh9 or Cydia

You can use Tiny Umbrella or Cydia (if it’s already on your device) to back up your SHSH Blobs.

1. Device does NOT need to be Jailbroken in order to save SHSH
2. It does not matter what firmware version is on the device TinyUmbrella will get the currently signed firmware by default.
3. TinyUmbrella saves the file locally AND sends the request to Cydia so Cydia will have the SHSH as well.
4. If Cydia’s TSS server is down, your only option will be to use TinyUmbrella for restoring through iTunes
