Just do a full reflash it will tell you its in an unknown state but it should take the full reflash, at least the ones I've done.

Did you try a FULL REFLASH?? Its under the flash menu, then there are 2 reflash options use the "program pcm operating system and calibration" I think since you disrupted it you'll need a full reflash now?? If not maybe someone will have more info. Good luck man.

for giggles...unplug your batter for a while and try it again...also, is your battery pretty much fully charged now? I have seen the battery have low power and have this issue
