Chosen Solution
I’ve tried replacing its battery, flex/flat sensor (that attached with the flash, which measure the battery temperature) and its usb port, but no success. Still no charge. The battery accepts being charged outside the device, in a external li-ion charger, with no problem.
Ok, I’ve done that… fixed it. Since I had another G4 plus at my desk with a malfunciotining thermistor, I`ve never even bothered myself to check its software, but that was the problem. However, after reinstalling stock rom, I remembered that I’ve forget to remove its google account… and surprise to me, the G4 owner doesnt remember her password. It has that new FRP (released in June, if Im not wrong) that, in this case, essentially bricks it. Any hints on how I can solve this?
