: Use a tool like WinRAR or 7-Zip to unzip the .rar archive. Inside, you will typically find a .bin or .hex file.
: Open your TV and locate the Flash Memory chip (often an 8-pin SPI Flash chip) on the Mainboard .
: You will need a hardware programmer (like an RT809F, RT809H, or CH341A) to flash the chip directly.
: Flashing the wrong dump file (e.g., from a different board version) can "brick" your TV permanently.
: Connect the programmer to the chip (using a clip or by desoldering) and use the programmer's software to write the downloaded dump data onto it. Safety and Risks
If your TV still turns on and you just want to update the software, you may not need a "dump" file.
