[Solved]My lg shows insert battery when connected to usb or wall charger.

Hello all! Here's my problem:
After i flashed my ks20 to a v10a rom it will shut down and display a "insert battery" animation when connected via usb or to a wall charger. I tried different roms (by flashing in emergency mode) but the difference is maybe a few minutes more before shut down.

Has anybody experienced something like this? or even has a solution to it?

Since i had no answers i did a little research and thanks to raykisi's link to the service manual i found out that the reason for this behaviour is charging circuit failure.
So if anyone has the same problem then i guess there's nothing you can do but to change the mainboard. Except if you are good enough to locate and replace the busted components.
