Some background info:-
I have 3 mini0801 cameras, approx. 2 years old, all have performed perfectly until 2 weeks ago. I bought a new car and moved the front/rear 801s from the old car and installed in the new one. Bad move!
Rear camera stopped working within 3 days, solid red led when powered from charger but nothing when not connected to charger, buttons not working. Completely dead.
Ordered a new mini0806, installed it in front, moved working 801 to rear. That too packed stopped working after 2 days. Exactly the same problem. Now have 2 bricked cameras.
At this point I checked the rear power supply, suspecting it might be faulty and causing the 801s to brick. However when checked with multimeter and scope it checks out fine. Replaced it anyway.
Bought a mini805 and installed it in rear, used original 801 gps mount. It's working fine BUT it can't get a GPS signal from the 801 base, it does get one from the base that came with the 805.
At this point I decided to try to rescue the 801's by following the instructions regarding DirectUSB which I found on this site and also replacing the batteries just in case.
Disassembled ok, batteries replaced, put the cameras on charge and checked that batteries were ok using a multimeter. They look good, holding charge.
Sadly, absolutely no improvement, both cameras still bricked.
Installed DirectUSB and purchased an OTG USB cable. Tried to connect cameras to PC using the OTG cable but no response from the PC.
Checked OTG cable by attaching the 3rd, working 801 and that connected via DirectUSB no problem, drivers installed all good.
So, I'm about to give up and throw the 801s in the bin !!
Just before I do so, does anyone have any other ideas or tips that might help to un-brick them ??
Thanks for taking the time to read the above..
