1. Power the
Murus off at the mains or by using the rocker switch underneath the board.
2. Plug the
USB stick into one of the non-touch USB ports on the front of the Murus.
3. With the
power button on the front of the Murus held down, turn the power on – within a
few seconds, the board should begin the reflash. When screen goes blue and it
says updating let go of the power button.
When the board comes back up (it will take a little while)
it should be now all be working. You will need to re-join the Murus to your WiFi network by tapping settings.
