Hi, I have Firmware 1.13 and im trying to downgrade to either 1.11 or 1.12 but im getting an itunes error when i do the process. I Keep getting the Error "1602" problem. Ive tried googling and searching but everyone saying uninstall itunes etc. ive tried 2 times and rebooted but the same problem still exists. Does anyone know how to fix this problem?
