Getting access

Opening the device

There's a tutorial by Christian Oberdörfer (German) on how to disassemble/open the device.

Serial console

You'll need to connect a 3.3V USB/TTL cable to the J8 pin header on the board. Only connect RX, TX, and GND. Do not connect VCC!

Vendor bootloader (brnboot)

Press space three times in a row right after powering the device to get into the bootloader (brnboot) menu. You'll get this:
