I have gone through all of the solutions above with my Kindle model D00901. Resetting with the button and draining the battery did not work, but guess what did. Hold down the "Alt" button and the "R" simultaneously for a few seconds. Instant reboot with all files reloaded properly. Thanks so much for that little tip as I was about to go bonkers. This item is essential for my education.
