Lenovo L490 Supervisor Password reset via rt809h

[bhteam]

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.
