Archive named M26GT4V2-LF, 446 KB ZIP, apparently for a board model M26GT4 in a V2 version with LF suffix. The name does not specify the file type, so extract and inspect it first; small packages like this are usually firmware. The version marker matters, so compare it with what is printed on the PCB before using any image. Before reprogramming, back up the existing flash chip with a programmer and verify the dump size matches the chip capacity.
