I think I've got a brick! I was (re)flashing my Zaurus,(something I do "too often" according to my wife!) when the power went out mid flash. The lights on th Z went out, and now it won't do anything. No lights, no power, nothing. I was reflashing the original Sharp ROM when this happened. Is there anything (short of returning the thing to Sharp for repair) I can do, or is it a lost cause?
