Stuck in recovery mode with a tethered device
I was jailbroken on 5.0 tethered and I wanted to unjailbreak to 5.0.1, but now I am stuck in recovery mode, none of the kick out of recovery mode tools like recboot, tiny umbrella and iReb works for me. when I try to restore using iTunes to download the firmware it always says the firmware is corrupted, no matter which usb part, mac or windows or not even what computer I use. if I choose a firmware myself it gives me the 14 error or 11 error. I have tried choosing firmware in pwnd dfu mode, in normal dfu mode in recovery mode but every time it fails.
please help me
