sorry for the lack of information, unfortunately when a repair doesn't go as expected I start to panic, basically if I connect the controller via USB it flashes as if it were interrupted, only if I connect the battery it flashes normally, it is not recognized via USB to the PC , only via Bluetooth is it recognized. Now I think the culprit might be ic bd92001.
P.s the only scratch I made is here and I don't think it's his fault
