Hi, this is a warning for everyone that has problems with original Blackview charging cable.
My phone wouldn't charge, or charge very slowly. Data transfer miraculously worked. I thought that original charger is too weak, so i modified other micro usb chargers to work with my phone. I never used blackview original supplied charging cable. Then a few weeks ago i tried again and it fried motherboard of my BV6000. When looking for a problem I noticed that flat cable that connects OGT board with mainboard gets very hot. That is probably the reason the phone didn't charge, because it could transform energy to heat instead of frying itself. Well, the last time I was not so lucky and the phone died. Today I opened up the cable to see where is the problem. As you can see from the pictures supply + cable is in short with data pin. Two strands of wire are soldered to the pin, other strands were in contact with the second pin.
If you have any problems with original cable I recommend you to throw it away and use any other cable. Even if Blackview itself recommends only original cable.
