When I read your comment, I realized that it was almost certainly the hardware that was causing its difficulties, when I first assembled the camera a week ago everything was fine and worked fine, after a few days I updated to version 1.9 and from that moment as I connected the rear camera to the main unit screen of the main unit freezes + "1080p+1080p" to " 1080p60" mode. I tried to go back to version 1.5v but it didn't seem to help.
It just doesn't make sense that something happened to the cable or the back camera because these worked fine before updating
My camera connection is with a hardwire 3 kit.
