Ok. I'm trying to upgrade my N800 to the latest firmware. I'm on a Windows machine and I followed the directions as posted, but at some point in the upgrade process the little N800 shutdown (I think) and the upgrade stopped. I tried to restart the tablet and put it back into 'USB mode', but it won't seem to go into that mode. It also doesn't seem to want to start! It will sometimes startup and goto the white Nokia screen, sit there for a few seconds and then go dark. Other times it won't start at all (i.e. holding the power button down) does nothing. If I pop the battery out and then put it back in it seems to power up after that, but still cycles through the Nokia screen and then goes dark.

Any ideas?
