@knc1: I tried all of that, made sure to create the file without extension (I made a txt file and took off the .txt) and made sure to unplug it.....it's still looping back to System Diags after the Kindle logo screen.

I even went back to check if I had mistyped or something, but the file was still there and typed correctly.

And yeah, I'll definitely try not to sign off. Thanks.

@Yourcat: yeah, I did the Device Setting before and it lets me ''exit'' the diagnostics screen only to lead me to the another screen "DIAGS EXIT Please use serial port"

EDIT: Never mind I take that back, @Yourcat, it appears that if I try to "<EXIT DISABLE>-Disable Diagnostics" choice specifically (under the "<o>-Reboot or Disable Diags" option on the main System Diags menu") I get the "device_info.xml not found <Run Device Setting.>" screen, which doesn't get fixed even after running Device Setting multiple times. If I choose "<EXIT LOGIN>-Exit to login prompt" on the same screen (Reboot or Disable Diags) I get stuck completely at "DIAGS EXIT Please use serial port." If I use
"<EXIT REBOOT>-Reboot System" on the same screen (Reboot or Disable Diags) I get stuck momentarily on the "DIAGS EXIT Please use serial port screen"--then the screen flashes and loops once through the kindle logo and back to the System Diags screen. Weird.

So I decided to go and take a look under the diagnostic_logs folder in the filesystem, and there sure isn't a device_info.xml file anywhere. I see a whole bunch (41 to be exact) files named "InvalidTestName_1.16.611.249627_B0540907450300MG@ ..." (the ellipsis represents the numbers 1-41, since there are 41 of these gz files). I'll upload the last one as I'm pretty sure its a log of something.
