It's not for sale, and all the ones I've found on the internet are fake. See the videos I posted see everything that was done by me and it still doesn't work for the T14, if you managed to do it on another model I believe, but if you do it on a T14 explain how you did it, because here no one has ever manifested saying that did something T14, only T490 or T490s using a rt809h
    with vertyanov and RT809H works perfect for T14

    Do you have a backup of the MEC1663 of a T14? There's a way to post it here. Unfortunately, I don't have easy access to Vertyanov, all I found are fakes, and to import an original is very expensive. I'm in a corrupt country that charges high taxes on imports.

      I don't know how your programmer works since I never had one. I can assume that the chip has a jitag lock, that is, you need to first erase the chip, and then upload the firmware there and then restore it with a prom dmi utility.
      The firmware you need can be taken from the BIOS update by first deleting the bytes at the beginning of the file.

        A new version of the Vertyanov program has been released where, at the request of users, the interface for working with MEC chips has been simplified

        You can download it from this link:

          what would be a "prom dmi utility" the EC has already been extracted and edited from the bios downloaded from the site.

            You do not even need new firmware.. just write back the backup you made.. password is not in the EC firmware but in a "secure place" on the EC controller, so blanking the chip also erases the secure area.

              I know that, the problem that is not backing up correctly, the file is empty! That is, there is no point in empty backup to insert back into the machine, so I asked the question above.

                After a lot of persistence I was able to remove the bios password from T14! I believe that few here know how to do it and no one shares it, I understand that certain types of information are not shared and are sold! But I persistently come to inform you that the (Thinkpad T14 1st 20S1) was unlocked by an RT809H the only programmer I have. Here are photos in the attachment, now all that remains is to reverse the bios information, but I had taken a photo first of all.

                  Finally, I managed to solve this damn T14 again. Now it works perfectly without a password and without computrace.

                          This model is not unlocked through a patch, only through the jitag programmer Vertyanov

                                I asked if you know the procedure!! Forum autocorrect doesn't work for you. My auto-patch works for your model.

                                        Inform the complete model of the laptop, being possible a photo of the cover.
