... and after the reset my Kindle was successfully unbricked. Thanks again!
I got tired of that Ubuntu dropped connection thing, and just uninstalled nmcli. But now, every time I reboot linux (not often), I have to type "sudo ifconfig eth1 up; sudo dhclient eth1". Oh well...
Glad you got it debricked. I will add your success report to the list in the first post.
EDIT: Added to success report list, which is getting rather long. Perhaps it is a good thing that only ONE PERCENT of the estimated successful debricks have been reported (based on download counts). If that "Success Report" list gets much longer, it may need its own thread.
