Testing ROM for Dell Venue 8 3830 (LineageOS 14.1)


It's in a very early stage. It boots, but lacks several resouces.

Was build using as base Asus T00F lineage source files

I'm posting here asking for help to implement/fix missing features (if anyone still interested on such old device)
All source code to build is available on github (links bellow).


Working
Boots
Display
Touchscreen
Wi-FI
Virtual Navigation Buttons
Sound
Rotation

Not working:
Camera
Bluetooth

Known issues:
- Sometimes when returning from sleep, backlight bright level is 0.
Workaround: You can blindly unlock and adjust bright bar and it will light again

- ARM apps not working due mismatches with libraries (Houdini)

- ADB only works using network. Not working using USB

- Observed battery is draining quicker than expected.
