Faulty dashcam (Kennington OX1)

I believe it's Viofo A129 Duo (purchased in 2018 I think), it's not the 4k version. Screen flickers, but before then it was failing to put the right date on files. The rear camera might be working fine for all I know, I have no way to test it, there is a long USB cable with it. Maybe for someone who wants to tinker.
