J'ai vu ça sur le site de Suntek:

There are 3 steps to proceed system upgrade:

Step 1: unzip and copy the FWR801.bin to a new TF card and insert this TF card into your camera.


Step 2: switch from OFF to TEST, there is red LED keep flashing about 15 seconds, then camera screen will light up.


Step 3: delete the FWR801.bin from TF card(format sd card or connect to PC via usb cable to delete), then switch TEST to OFF and restart camera.


As tu suivi cette procédure? As tu bien effacé le fichier.bin (step3)
