This thread is for the Asus Zenbook 14X OLED UX3404 UX3404VA.
Compare the board number printed on the PCB (near the RAM slots or under the battery) with the files before you flash.
Files wanted for this board
- BIOS (full SPI chip dump, .bin)
- EC / KBC firmware, if the board uses a separate EC chip
- Schematic (PDF)
- Boardview (.brd / .bdv / .cad)
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.
Before flashing, always read and save the original chip. It holds the serial number, UUID, MAC address and ME data for that exact machine.
