About this board
This thread is for the Asus X421JA X421YA X421JAY.
Compare the board number printed on the PCB (near the RAM slots or under the battery) with the files before you flash.
What this thread covers
- BIOS (full SPI chip dump, .bin)
Common cases: dead board after an interrupted BIOS update, ME region errors, missing serial number or UUID after a board swap, or a password lock.
Back up the original dump first — it contains machine-specific data (serial, UUID, MAC, ME), and you will want it if anything goes wrong.
If you have a working file for this board, please share it below. More files: search Asus X421JA X421YA X421JAY in File Finder.
