    Explain to me what exactly you did?

    Did you clear the password with two blank passwords and a clean security chip?
    Then did you reset your BIOS to its original state?
    Otherwise, try creating a password.

    As indicated, the password is stored in the 24RF08.
    You can short SDA and SCL.
    You'll find information here or on other forums for that.

    SDA and SCL are also found on the WWAN port.
    The bypass can also be performed here if accessing the 24RF08 is difficult.
    Doesn't work all the time.

    Or read the EPROM with LMU.
    See if the password is still there.
    Take pictures of the blocks and show me.
