[LG Optimus L3 II, L5 II, L7 II, L9 II] neutrondev:
What is working:

All lights (Flash, Led, Button light)

Storages (Internal+External)

All sensors (Proximity, Compass, Acceleration, Orientation)

Bluetooth

Wi-fi

GPS

All Tetherings (Wi-fi, Bluetooth, Usb)

Root

Camera

Audio

Offline Charging

NFC

Known Issues:

Fm radio (this will not get fixed, don't ask about it, sorry)

On video recording if you are taking video begging with a frame that is not still you might get stuck. Better start still and with manual focus. If video gets stuck reboot device.

Sometimes when you turn GPS off it will GPSLocationService will keep device wakelocked (this is not a bug from our device but AOSP). If this happens and you lose battery. Reboot device.

Keyboard does not vibrate (CM source bug). Search another keyboard if you are bothered.

Mic gain will be weird because Lg used custom audio routing so the top one will have more gain so that means a little lower main mic sound
