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.
Je kan dus proberen om je IPA bestand te verwijderen vanuit:
C:\Users\USERNAME\AppData\Roaming\Apple Computer\iTunes
Na het verwijderen even een reboot geven aan je pc/laptop.
Vervolgens even opnieuw je iPad herstellen.
