2. Access Main Board: Remove the TV’s back panel and locate the BN41-02353B main board.

3. Locate eMMC Chip: Identify the eMMC chip on the board.

4. Connect Programmer: Use RT809H with an eMMC adapter or test clip to connect to the chip.

5. Backup (Optional): Read and save the existing firmware before writing.

6. Load New Firmware: Import the downloaded firmware file into the RT809H software.

7. Write Process: Start the writing process. Wait until verification completes.

8. Reassemble and Test: Once flashed, disconnect the programmer, reassemble the TV, and test functionality.

Safety and Handling Tips

• Always work on an anti-static mat and wear grounding equipment.

• Never power the TV while the programmer is connected.

• Double-check chip orientation before connecting to the programmer.

• Take care when soldering; damage to board traces can permanently disable the main board.

Common Questions & Troubleshooting

Q: Can I repair the TV without removing the eMMC chip?
Yes, if your RT809H supports ISP (In-System Programming), you can connect via test points without desoldering.

Q: What if the firmware does not match exactly?
Always match the main board (BN41-02353B) and panel type. Firmware from different regions or panels may result in display errors.

Q: Can I use firmware from a different Samsung TV model?
No. Always use the firmware specifically designed for the UE55J6300 model and the same main board variant.
