- MicroSD card (8GB to 32GB recommended; avoid 64GB+ as they often use exFAT).
- Your Fa4’s serial number (located under the "System Info" tab).
Common update problems and fixes

- Stuck in pairing loop: reset to factory defaults after update and re-pair devices.
- Audio distortion: confirm correct codec/settings; test with different source devices and cables.
