Saving onboard SHSH blobs of current iOS version

Legacy iOS Kit can also be used to save on-board SHSH blobs of 32-bit and 64-bit iOS devices.

Notes

• Supported devices: iPhone 4, iPod touch 4, all A5(X)/A6(X) devices, all 64-bit (A7/A8/A9/A10/A11) devices
• Not supported devices: iPhone 3GS, iPad 1, iPod touch 3
• Dumping blobs is supported for all iOS versions 4.0 and newer.
• For 64-bit devices that support it, better go to SSH Ramdisk instead.
• The steps below requires the device to be in Normal mode, jailbroken, and with OpenSSH installed.
  • For iOS 16+ devices, you will also need the following: libkrw0 1.1.2, libkrw0-tfp0 1.1.2, libx8a4-1, x8A4
  • You may install these from this repo: https://cydia.ichitaso.com/secret-repo
  • You may also install debs from here: https://github.com/Cryptiiiic/x8A4/releases

Usage

1. Prepare your iOS device by jailbreaking the device. 32-bit devices may follow the steps in the Restore to 32-bit device page for entering kDFU mode.
   • For not jailbroken methods, you may also go to the DFU Advanced Menu section of Troubleshooting
2. Start the script and select Save SHSH Blobs -> Onboard Blobs
3. (32-bit devices only) Download and select the IPSW of your current iOS version
4. Follow the given instructions. If the process is successful, valid SHSH blobs of your current iOS version will be saved.

• If blob dumping fails for some reason, try using another USB port/cable/hub.
