Maintenance process: the machine is caused by falling. Generally, there is no IMEI, but Baseband has a problem when identifying power amplifier through RFFE bus. According to the maintenance experience, the power amplifier near IMEI Switch is mostly broken, so the power amplifier is disconnected by directly removing the motherboard.
