Stock firmware image named YAHIKO and dated 20251224, stored as a 16.0 MB ROM file. The name gives no brand, model or board number, so the target device has to be identified from other sources before use; YAHIKO appears to be a project or code name. A 16 MB image usually corresponds to a 128 Mbit SPI flash chip. Read and keep a copy of the original chip first, compare its size and contents layout with this file, and only then write it with a hardware programmer to restore a corrupted or failed firmware.
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 @lappysan. Enginerys does not host this file.
