To restart in safe-mode, press all four buttons at the same time. The screen will first turn completely red. Motion will restart in safe-mode a minute later. Once there, you will be able to either :
- connect to a computer via USB and modify files, retrieve logs, add tracks and maps but most importantly update the firmware,
- continue to normal-mode by pressing both the lower-center and upper-right buttons together for a few seconds.
