Gotcha. Doing this allowed me to run fastboot. It initially didn't reboot. I had to unplug the cable and had to plug it back into my Windows machine in order to get it to reboot. Once it did, it flash back to diagnostics mode where I N) U) Z) X)
and was able to successfully ssh into the kindle. Then I mounted the mmc partition and moved the files back and all was restored.
It was a bit of touch-and-go. The Kindle and drained the battery and refused to reboot. I had to remove the battery, which was a bit involved. I couldn't find any articles about how to remove it but will post something on ifixit.com with pictures and stuff.
But for those of you that ABSOLUTELY NEED TO DO THIS
, you need to take a spludger
and lift the bottom of the back panel. It's a bit tough, you can safely force it (within reason of course). Once done, you can slide the back panel down with a bit of effort.
Thanks again everyone, but especially to geekmaster!
