Firmware for the V59 family universal TV board, written t_vst59_031 here, with Samsung remote support indicated in the name. The number 149664 is probably an internal build or file identifier. The file is a 2.61 MB RAR archive, likely holding a single SPI image. The 031 suffix usually distinguishes board sub-variants within this family, so match it to the marking on your PCB. Writing is typically done by USB or with an SPI programmer, and the original chip should be read and saved first in case the panel setting is wrong.
