Hey, I can only find those USB connector boards online where all the chips on it are missing. Does anyone know where I can find a proper replacement board?

Hnas Krack - 返信

Same problem for me. I just bought a "1:1 replacement" board, which has missing chips and does not allow data transfer. Charging was possible (only very slow). However, after I changed to the old board back again to return the new faulty one, Charging was now not a problem anymore. Maybe I tightened one screw, which has been loose before?
