@mrt10001 When the device is unplugged, after holding volume- and power for long enough, it eventually boots into Ubuntu. Sometimes it takes 20 seconds sometimes it takes 60. It never loads the bootloader any more. EDIT: ok I got it to show up with bootloader for about a second by holding power for 10 seconds as if I was turning it on as usual, then releasing when it vibrates, then volume down and repressing for another 10 seconds. Going to experiment some more. EDIT 2: for anyone else who ends up with their device in the same state as mine: the trick was to continue holding down both buttons and click on the touch screen while still holding them down, and then I was able to release once it started the bootloader. Thanks very much for the help! Hopefully I'll be good from here.

@spaceman_spiff Not my fix, read about it on the forum or TELEports, but if it works, good. It is one of the tricks to remember for any sort of connectivity issue on UT, try switching airplane mode on and off first
