I just download a version for here and flashed it with TWRP adb sideload
also change your slot

@MrT10001 I can get a day of battery on UT16

@MrT10001 I just tried multiple reboot and every one crashed
also @Pingu I was using v22 postmarketOS, but edge should be better, so it doesn't feel like beta

I already had downgraded and used UT 16 and wanted to try UT 20, but there were some issues
then upgraded to android 11 and tried postmarketOS, but it feels like a beta
so I want to try UT 20, but it is not working

is UT 20 planed for OnePlus 6, or will it only support UT 16?
