[Treble-Enabled Device Development A/AB ROMS] ccxxx:
I installed this rom on an Alcatel 1 that I bought for 35€ from amazon warehouse deals. Amazing that this works, thanks.

One issue, when trying to set an alarm there's an error about notifications

11-17 22:57:37.475 26597 26824 V AlarmClock: *** notifyChange() id: 2 url content://com.android.deskclock/instances/2

When the alarm should trigger, there's a permission problem
