My wife's Kindle 3 was frozen, and nothing I had tried worked. I saw a Kindle 3 on E Bay with a cracked screen very cheap. I took a chance and ordered it, and used the guide (sort of in reverse) to remove the guts from the one with the broken screen to replace the guts of ours. That way I didn't have to worry about the glue holding the screen to the case and she got to keep her case that already had her name on it! It came on immediately and after a few more minutes to deregister, re-register, update the firmware and transfer our titles, it was ready to go. I'm keeping the old motherboard (especially the battery and wifi connector) and screws for replacements. Thanks for the great guide! W. A. R.
