Kindle PW3 Diagnostic Mode Error

Hi,

I recently bought Kindle PW3 and I jailbreaked it using these instructions: http://www.mobileread.com/forums/sho...d.php?t=270651
Everything went smoothly. Afterwards I installed KUAL, Helper +, KoReader, Python and Librariansync. I was transferring books from Calibre to the Kindle, when I forgot that restarting it while connected to the usb cable would start the Diagnostic Mode.

My problem at the moment is, that I can't exit it. I tried disabling diagnostics, which just shows: Elmo firmware is not matched Need to update firmware
I also tried making DISABLE_DIAGS file in the root directory, even doing factory restore with DO_FACTORY_RESTORE file, but nothing worked.
Here is a screenshot what I can see on the kindle when it's connected to the pc: https://i.gyazo.com/a0fbe75b9ea13351...5b2c804e83.png

I don't have USB networking installed so when I try to enable this, it doesn't work.


Any help would be really appreciated!

P.S. After some time leaving the kindle alone, and doing all the tests in the diagnostic mode, it actually rebooted to the original mode.
