    dont know (not tried)

    I used these keys in WinFlash:
    /sa /sn /sd /sp /svs /sv BIOSSL.FL1
    /sa Skip all BIOS checks.
    /sd Skip BIOS date check.
    /sn Skip BIOS part number check.
    /sp Skip BIOS product ID check.
    /sv Skip BIOS version check
    /svs Bypass the BIOS version check warning when flashing same version of BIOS.

    I understand you.

    I've just used this command: pflash /sa /sn /sd /sp /svs /sv BIOSSL.FL1
    (from your bat file)

    But I've got the message: "Failed to authenticate image!(Fail: UNSUPPORTED)"
    PRESS ANY KEY TO EXIT

    I wrote this verbatim (In DOS environment)

    What should I do next? Waiting your command

    none of them are the SLIC mods, in the first - AES-NI is enabled & WLIST check is disabled, in the second - WLAN whitelist check is disabled
    To Enable SLIC 2.1 you must use marker utilities https://forums.mydigitallife.net/threads/slp-marker-file-update-utilities.9055/page-15#post-478696

    O.K., thanks for clarifying - but I don't see marker utilities for the X201 or X220 in this linked post. Most of the links are 10 years old and 404'd, and the closest I see is a SLIC mod for the X230.

    Alright then, will proceed with activation. I have another X220 which will eventually require activation, though not for a quite a while. Will get back to you again if I need your help - thanks for everything.

    it is a very simple process - install Lenovo certificate and correct OEM: SLP key

    Create a file results19.rar for that another X220 laptop and upload it
