iPad SHSH Blobs

Since Spirit is a userland jailbreak, the exploit it uses is very likely going to be patched in the form of new firmware. It is important to save your iPhone / iPad / iPod touch SHSH blobs now so that you don’t loose the ability to downgrade (and re-jailbreak) your device should you accidently upgrade.

There are number of ways you can do this. You can either use AutoSHSH, Firmware Umbrella or directly go through saurik’s server. The following guide uses AutoSHSH to save SHSH blobs of iPhone, iPad and iPod touch.

Step 1: Download latest version for AutoSHSH. (Download link).

Step 2: Start the program and plug in any ONE (iPhone/iPad/iPod touch) in recovery mode. To do this, turn off your device and hold down the “Home” button while connecting the USB cable until you see “Connect to iTunes” message and logo on your iPhone.



Step 3: Click “Grab SHSH Blobs Automatically”. AutoSHSH will now grab the signature. Once complete, it will ask you to save it on your device/machine/usbstick. Make sure you keep it in a safe place as you might need it when you want to downgrade back to the older firmware. AutoSHSH will also automatically upload the signature file to saurik’s server.


Make sure you save the signature for your iPhone, iPad and iPod touch on file before Apple releases the next firmware and eliminates your ability to jailbreak without a new release from the Dev Team.

  5. H? Well, it is basically is a unique signature wh is checked against Apple servers whenever you decide to restore the firmware on any of your iDe(iPhone, iPad and iPod touch). Once a new firmware is released, Apple stops signing the older firmware, hence making it impossible to restore back to the older firmware from iTunes. Now to “why is it important to save SHSH blob”

  7. For "Pretty cavalier....installing something without a back-up plan on a $500+ device! Idiot... ", you're the idiot, the shsh backup can be done after the jailbreak.

  10. If you're using a Mac, AutoSHSH isn't going to work. It's a Windows app.
