Firmware dump for the ASUS X550CL mainboard, revision 2.1, used in the ASUS X552CL laptop, and marked as tested and working. The rar archive of about 3.6 MB should hold the SPI flash image, which you write with a programmer such as a CH341A or RT809 to revive a board with corrupted firmware. ASUS often fits one main board to several retail models, but check the revision on the PCB first. Save the original chip contents before writing, in case serial or other data must be restored.
