How to enter flash mode

Fastboot: Hold down POWER and VOL DOWN. Use volume buttons to navigate to Fastboot and press power.

Installation

What doesn't work

WiFi

Kernel driver compiles, but returns I/O error when trying to enable it via /dev/wmtWifi (as explained here).

Battery capacity

/sys/class/power_supply/battery/ returns static data, capacity is always at the level it was during boot.
