⚠ Safety & Operating Precautions
Flashing firmware from BOM 1 onto a BOM 4 motherboard can disable Wi-Fi/Bluetooth or cause remote control unresponsive faults.
Television manufacturing involves iterative engineering changes during a product's market availability. When a component vendor changes (e.g., swapping a Realtek Wi-Fi module for a MediaTek chip, or changing the tuner IC), the factory updates the Bill of Materials (BOM) revision (e.g., BOM 1, BOM 2, BOM 4/5).
Why BOM Matters for Firmware:
- Tuner Incompatibility: The TV will fail to lock RF channels if the tuner driver in firmware doesn't match the physical tuner chip.
- Wi-Fi Grayed Out: A mismatched Wi-Fi HAL driver prevents the operating system from enabling the wireless adapter.
- Remote Control Mapping: Remote control IR receiver protocol tables differ between BOM revisions.
