now i really screwed up. did my backup then decided to do the hc upgrade from tipster. downloaded the zip file and followed the instructions. when i tried to reboot at the end, all i get is the white coby screen - nothing else. tried to restore my backup and i'm getting a md5 mismatch also getting e: can't mount /dev/block/mtfblock5 been searching for a fix but right now i'm hosed. i can't boot so i can't even turn off the tablet. all i can do is to boot into clockworkmod recovery (holding the silver button) or the white coby logo (without holding the silver button). if anyone can help me, please do. thanks.
