Shame the battery out trick didn't work. I know it worked for a couple of guys on here (can't remember what the threads were now).

I don't think it's a write-off by any means, not unless you've thrown it under the wheels of a truck. Just a case of waiting until/finding the right fix. But having said that, just hope the car charger hasn't banjo'd something.

I'm not a Maemo Wizard like most of the guys here, so all I can say is just try all the avenues.
