ZIP firmware archive for the ASUS X415JP, with F1.306 in the name, which looks like a version or revision tag. At 5.30 MB it probably holds a BIOS image or update for this VivoBook model, but the name gives no chip size. Technicians use such files to restore a dead or looping board, either through an update tool or by writing the image straight to the SPI chip. Read and keep the original chip contents first. Confirm the image size matches the flash chip and that the board is an X415JP.
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 @afsbiosfree. Enginerys does not host this file.
