Zip archive named builds1 that carries no device details, the same name and 6.85 MB size as another entry in the index, so it is probably a duplicate copy. Nothing in the name reveals the brand, board or firmware version. Extract it and examine the contents with a hex editor or firmware tool to see what it actually contains. Treat any images inside with caution: confirm the target board, match the image size to the flash chip and save a backup of the original contents before programming.
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 @vinafix_bios. Enginerys does not host this file.
