Tips, Tricks, Caveats

FEL mode

The VOL+ button triggers FEL mode.

Adding a serial port (voids warranty)

UART pads

Device disassembly

Remove the 4 screws. Now gently push your Plastic tool between the plastic outer edge and the metal back cover. Try to go around the whole board until you hear some clips pop, and do this until all clips have released. Be careful when opening the device, as the Wifi antenna is taped to the back cover.

Locating the UART

On the back of the board, right next to the (back of the) SoC, there are two pads. All you need to do is solder on some thin wires according to our UART howto.
