How to unbrick an Amazon Kindle Paperwhite™

This guide instructs you in how to unbrick an Amazon Kindle Paperwhite. The consequences of following it are your own responsibility. This method (opening the Kindle and using the serial interface) should be a last resort and should only be considered if other methods fail

The Guide

0. Pry open Kindle using a prying tool
1. Unscrew the screen and remove it from the base. Note that there's a screw hidden under the adhesive at the top in the middle
2. Solder tin wire to serial ports on the bottom
3. Attach tin wire to USB TTY device (order is ground, RX, TX, from the kindle's perspective, where GND is the smallest pad) and plug USB TTY device into your computer
4. Open Putty on your computer in serial mode, with the serial port specified as your USB device and baud configured to 115200
