Hi everyone, I have a K2 unit since about a year or so and everything was working as expected until today. While changing the SD card for a bigger one, I noticed that the DVR wouldn't stay ON normally and was constantly rebooting. At first I thought that the new SD card was faulty so quickly put back the older one. But that didn't change a thing. So I tried to debug : - Connected an external USB power supply instead of the bike's own battery -> No change - Tried to boot without SD Card at all --> No Change - Tried to reflash the firmware --> Firmware did flash OK but the issue remained - Tried to boot without cameras & GPS connected --> No change - Then I tried to connect the Rear camera to the Front connector on the DVR --> DVR did boot fine ! - Tried to connect everything back (motorcycle battery & GPS) but still with only the rear camera plugged into the Front connector on the DVR --> Still Works Ok - Reconnect both cameras to the correct positions on the DVR --> The Issue reappears It seems that as soon as I connect the front camera, the DVR refuse to work and goes into a bootloop. How can I further diagnose the faulty part ? Should I return the front camera ? Here is a quick video of my problem :
