    Lenovo L490 Supervisor Password reset via rt809h

    Hello fellow caps

    I want to remove the Supervisor password on a Lenovo L490 laptop.
    SIO is ITE8227
    I understand that I need a jtag tool like RT809H to be able to talk to the chip and read/erase/write.
    My question is:
    Is the RT809H compatible with reading ITE8227 chips? I cant seem to find info on that before ordering the RT809H.

    Have you tried with autopatcher? I can unlock L390 with this tool so i think also work with L490.
    In case you wanna read and remove password from EC, you can buy VERTYANOV_JIG

      Also interested as I have an L490 with password here, i5 8th gen, 20Q6-S06000. 32MB BIOS.

      RT809H seems cheaper and more available than Vertyanov.

      I tried autopatcher but the laptop wouldn't boot with the patched file.

      BIOS dump attached if it is of interest to anyone.
