Process

iTunes side

  • As a result, users can not restore their iDevices using iTunes or earlier versions of 3uTools. 3uTools for 64bit, 3uTools is one of the best tools for iOS users. Launch 3uTools and Click Flash & JB - Firmwares to download the iOS firmware to your iDevice.
  • Due to asr being patched, the SHA signature is automatically changed and after being resigned the kernel will refuse to use it. Therefore proper kernel patches are required. If necessary kernel patches are not applied, it will fail to load asr and error 9 would occur during restore. Rebooting your PC may resolve.
  • I'm having a failure in idevicerestore when trying to update to 10.3.2 on my iPhone. Attached is the log. Looks like everything is working right up until the baseband tss request at the end.

iTunes has pretty much no say in how the restore goes along. It will send the DeviceTree, RAMDisk, and Kernel (respectively, as far as I know), but in firmwares 1.1.1 and up the program on the RAMDisk pretty much runs the show. On the Restore RAMDisk, it is called 'restored_external'. On the Update RAMDisk, it is called 'restored_update'.
