About this board

This thread is for the Toshiba Portege X20W-D PRT12E FATRSY2.

Compare the board number printed on the PCB (near the RAM slots or under the battery) with the files before you flash.

Files usually needed 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)

Usually needed when the laptop powers on with a black screen after a BIOS update, is stuck in a boot loop, or is locked with a BIOS password.

Before flashing, always read and save the original chip. It holds the serial number, UUID, MAC address and ME data for that exact machine.
