The MG motherboard was sent back with the warranty, and the figures on it were all wrong. It was replaced by a new one. According to the relevant public information, after the maintenance station replaces the motherboard, the maintenance station will send a replacement reminder to the headquarters, which means that the headquarters will use the new code to represent the original code. If it is not a service station, you can call customer service. Check the motherboard number by the host number.
