Phooey.
I did want to own a Kindle that had never been torn open.

device_info.xml (reformatted for this post):

    BATTERY_LMD="1408"

/>

Now, all I have to do is dig out the 'diags' kernel and system from it.

Edit:
One of the easiest Kindles to open yet.
Some double sided tape top and bottom edges holding the bezel -
Eleven screws and a couple of friction clips holding the MB/Screen assembly in the case -
And its apart.

Edit: (following day)
Darn but those serial port pads are tiny.
Six hours to solder one end of each of 4 wires.
And yes, these are not the first solder connections I have ever made in my life.

Edit: (another day passed)
but those connections work as if they where my first.
just love it when I have to troubleshoot my own handy work.
