Here's one link to what knc1 just described, you will need to try to get all the variables that your idme command is supposed to print I think? Although yours are still stored in non program memory, so I am it sure about that.
@hexadecimal, what is the USB ID of the device if you plug it into your computer now? This is to try to find out if your kindle is falling into USB download mode, like that poster.
When I was working on mine, I used this tool to monitor ish changes.
