BIOS image for the JRY-W87XX-CV1 board, marked in its name as 100 percent working and packed as a 1.21 MB ZIP. No revision or panel model is given, so check that the board revision and the connected panel match your unit before flashing. Such firmware is usually written to the board's SPI flash with a programmer to fix boot loops, a missing picture or a corrupted menu. Always keep a copy of the original chip contents in case a restore is needed.
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.
