About this board

This thread is for the T14 Gen 2 (Type 20XK 20XL) Laptop (ThinkPad) Type 20XLNM-D451.

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

Files listed for this board
  • BIOS (full SPI chip dump, .bin)
  • 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.

Back up the original dump first — it contains machine-specific data (serial, UUID, MAC, ME), and you will want it if anything goes wrong.

Hi!
I have SVOD4, RT809H, Vertyanov Jig. I can read the first 256K of IT5679 with SVOD4. There is the option to set 1024K, I set it but it reads only 256K. Any idea how to read the full 1024K content?

Do you have original vertyanov successor?
if you dont have contact PM will guide you.
 
It appears that SVOD4 reads only 256K by default of the IT5679, even if it is configured to 1024K. Attempt to verify software limits, other read modes, or employing RT809H/Vertyanov Jig for full dump extraction.

Yes vertyanov or Successor both support or read 1024kb
