Do not turn off the power during this process. Once the flashing stops or the TV reboots, the installation is complete. Safety Warning

Finding a "free" download requires matching your panel's resolution to the firmware provided by technicians on community platforms.

Plug the drive into the USB port of the T.R67.03.V3 board while the power is off.

Place the .bin file into the root directory of the USB drive (do not put it in a folder).

Installing the wrong firmware can "brick" your board, making it unresponsive. Always double-check that the resolution of the software matches your TV panel's native resolution. If you get stuck in a "Burning" or "Ageing" mode (cycling colors), you can often resolve this using specific remote codes or by re-flashing the correct software.
