Since this is "part 06," it is not a standalone file. To successfully use it, you generally need to have (Part 01 through Part 06 or more) in the same folder to extract the final firmware image. Important Safety Warning

Place the extracted firmware file directly onto the root of the USB drive (do not put it in a folder). Installation: Turn off the TV and unplug it. Insert the USB drive into the TV's USB port.
