The three wires should go on the pads outlined in red.

From left to right, the pins are TX, RX, and GND.

If you are finding it difficult to solder to the ground pin, try soldering to one of the shields, which would normally be where the blue outline is.

Using the resistors, diodes, USB serial adapter, and breadboard wires, build this circuit on the breadboard.

Then, using alligator clips, connect the wires on the "kindle" side of the schematic to the appropriate wires from the Kindle.

Plug your USB serial adapter into the computer.

Start your serial terminal program (like Minicom). Make sure to disable "Hardware Flow Control".
-

Connect the kindle battery.

You'll start seeing text in the serial terminal. When it says "Hit any key to stop autoboot" press a key.

Type in "bootm 0xE41000 " and press enter.

Tap "U - USB Export" on the screen.

Plug your Kindle into your computer through the Kindle's USB port.

Download the Kindle firmware from https://www.amazon.com/gp/help/customer/...

Open the Kindle drive on your computer and drag the .bin file into it.
-
Eject your Kindle and unplug it from your computer.
-
Press "Q" either onscreen or in your serial terminal.
-
Tap "Reboot or Disable Diags", or type "D"
-
Tap "Reboot System", or type "R"

The Kindle should now be booting into the regular OS.
-
When the serial terminal says "Press [ENTER] for recovery menu...", press enter.

Type "u" and quickly follow that with the enter key.

Your kindle will restore the firmware you copied over previously.
-
At the end of this process, your Kindle should be showing its bookshelf screen.

-
Unplug the USB to serial adapter, and remove the wires from the kindle.
-
If your wires are thin enough, you may be able to break them away from the pad, but be careful to not tear the pad off.
-
If you can't do that or just want to be safe, remove the motherboard and desolder the wires, then re-install the motherboard.
-
To complete the repair, close the device by following the process detailed in the beginning in reverse.

Merlin04, you do an excellent job at breaking down the tasks and guiding a person through the process!!
thank you for the fantastic guide. When trying to communicate with my kindle through the serial port however I only see symbolic characters with no sense. What should I do?
Describe what a boot loop looks like.
My Voyage gets stuck on the start screen (the one with a tree) and can't be powered down until the battery runs out of juice.
Do I have a boot loop going on or something else?
