@FrostDaemon according to these tests, yes on T-mobile https://codeberg.org/EricHeintzmann/UbuntuTouch/issues/23

@MrT10001 I did not use trwp just local update. But I did get it to go. I reset the phone, used the zip from the XDA link you put, then used a different computer with a fresh ubuntu install, flash UB24 from there it booted into recovery, I then flashed UB20 from the installer and was able to update to 24. Not sure why that worked but it did. Thank you for helping. EDIT so I posted that while it was updating to 24.0 and it rebooted right back to recovery and that was it, I was able to re flash 20.0. So I assume 24.0 just does not work on the 6t as of yet, which is cool since it is still new.
