please help i think i have honestly bricked my ipod. I had tethered and then tried to switch to untethered. The first time i forgot to end it with "reboot" Then i tried it again and i did "reboot" at the end this time. my ipod will not boot. I put it in dfu mode and run boothelper but that doesn't work. re-untethering doesn't help either. is there a way to reset the bdev to try again? please help im desperate!
