What can I do if my camera comes across unexpected system halt/automatic restart/boot failure?
Try a different angle of the charging cable and/or the cigarette-lighter adapter.
Remove the MicroSD card from the camera and see if the camera can boot without the card. If the camera can boot normally without the card, clean the metal contact points of the card or change another MicroSD card.
Make sure the charging cable is plugged into the socket closest to the blue light of the double-socket cigarette-lighter adapter.
Unplug and plug again the charging cable into the socket.
If the above means prove to be ineffective, please refer to the Firmware Update section.
