Once you have located and downloaded the correct firmware file (usually ending in .bin or .img), follow these steps to flash the board. Method 1: USB Upgrade (Easiest)

This method works if the board can still read USB drives during the boot sequence.

Format a USB drive to FAT32. It is best to use a small drive (8GB or less).

Copy the firmware file directly to the root directory of the USB drive. Do not put it in a folder.

Rename the file to the specific name required by the board (often MstarUpgrade.bin or update.img), if instructed by the source. Power off the TV completely and unplug it from the wall.

Insert the USB drive into the TV's USB port (use USB 2.0 if available).

Press and hold the power button on the TV cabinet (not the remote).

While holding the button, plug the TV back into the power outlet.

The indicator LED should start flashing rapidly. This means the update is in progress.

Release the button and wait. Do not turn off the power. The TV will usually reboot automatically when finished. Method 2: ISP Flashing (Advanced)

If the TV is completely dead and does not respond to the USB method, you will need hardware tools. Required Tools: RT809F or RT809H programmer.

Process: You must connect the programmer to the board's VGA or ISP pinouts and burn the firmware directly to the eMMC or SPI flash chip. This requires professional repair skills. ❓ Troubleshooting Common Post-Flash Issues

Upside Down Picture: If the image is inverted after flashing, enter the TV's Service Menu (usually by pressing Menu + 1147 or Menu + 2580 on the remote) and look for the "Mirror" or "Panel Flip" setting.

Distorted Colors: This happens when the LVDS map is wrong. You can also adjust this in the Service Menu under "Panel Settings."
