Firmware archive labelled CV950H-A42, a code that matches a universal LCD TV mainboard family, though the name gives no brand, panel or software version. At 324 MB the package is likely a full software set or eMMC dump rather than a small SPI image. Before flashing, compare the board code and suffix printed on the PCB, check the panel resolution and remote layout the software expects, and keep a copy of the original memory, as the wrong panel setting gives a dark or distorted picture.
