Zipped BIOS file for the ASUS X550JK, firmware version 303, judging by the .303 extension of the image inside. The X550JK is a 15.6-inch notebook from the X550 family. Technicians use such an image to recover a board with corrupted firmware by writing the SPI flash chip with a programmer such as a CH341A. Read and save the original chip first so the serial number and MAC data are kept, and confirm the image size matches the chip capacity. Also check that the board number on the PCB suits this X550JK release before writing.
