1. Resolder BT_ANT ORCheck the pad to be parted from PBA

2. Check out OSC101 signal & around component

3. Resolder R110 or changeCheck VRF3 from PMB6821If something wrong, change PMB6821

4. Using equipment, change BT chip

cf. BT chip ball size is very small you'd better consious this point

5. If no more check pointchange MPU or PBA
