I received my unit yesterday (bought from woot.com) and after I fully charge the unit, setup connection and loaded with a few apps from maemo.com, I think it choked on vim installation and locked the unit for hours, I have to restart the unit and only found it stops working, it will boot about 50% of the squence then restart, again and again, never could get to the main screen.

How do I reset the unit, or restore from the factory default? Helps are very much appreciated.
