Well, I don't have a D2G. In the world of Droid 1 though, we would pull the battery and hold the X key to reboot into recovery and try the rom install again or restore the backup we made right before trying the rom install. Is that not possible on the D2G? Do not try it if you don't know. Check out the D2G forum subsections for an answer. I mainly posted this to bump the thread. Good luck.
