How to enter flash mode

Apply USB/power while holding the volume up button to get into BROM mode. See Mtkclient for more info.

Boot with the volume down button to enter fastboot (?)

UART RX/TX pads are available near the SoC, partially obscured by the metal shielding. VBAT, VBUS, GND pads are also found labelled on the logic board.
