Firmware archive labelled GM5ZG8W_12L version 1.1, about 1.15 MB in RAR form, with no brand or device stated in the name. The label resembles a board identifier rather than a model name, so check the markings on the PCB before treating it as a match. Open the archive to see which image it holds and compare the file size with the flash chip on the board, since an image of the wrong size will not fit. If it does fit, write it with an SPI programmer, keeping a backup of the original contents.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
