Working firmware pack for the ASUS X553MA laptop, board revision 2.0, containing both the BIOS and the KBEC keyboard embedded controller firmware. The RAR is about 12.1 MB. When an X553MA shows no power, no backlight or a dead keyboard after an interrupted update, technicians program the BIOS chip and, if needed, the EC with an external programmer. Match the revision printed on the PCB, read and keep the original contents of each chip, and check that each image size corresponds to its target flash.
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.
