I've had my G1 for over a year. It was working fine earlier this evening, then I shut it down for a couple of hours. Randomly now it won't boot back up, it just shows an RGB screen with some information text and the phrase "serial0". Before going to this screen it flashes a gray screen with the text "No image file" I have not tried to root or do anything weird to the phone. I've taken out and put back both the battery and sim card. I've tried doing soft and hard resets. Anyone have any ideas?
