I've been using it for years just to download books in AZW3 format.
The 4G has been dead for awhile now but the WiFi still worked.
On Sunday it didn't want to download 4 or 5 books, so I just left it plugged in to keep the battery topped up and to see if those books would eventually download. I checked it today and the documents folder was completely gone. I tried to reset it by holding the power button until it restarted, and now it's stuck at about a 15% on the progress bar. Oh well, I've got more ebooks now than I can read in the rest of my lifetime so if it never recovers it's probably just as well.
