Use this to write back machine info. Info is on stickers at bottom. They start with 1S and 8S.

But still, what did you do with RT809H to get it working?

Re: mec 16xx dump with info block

After a lot of persistence I managed to remove the T14 bios password! 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 persisted, and I come to inform you that the (Thinkpad T14 1st 20S1) was unlocked by an RT809H the only programmer I have, as I don't have access to a vertyanov. Here are the photos in the attachment, now I just need to invert the bios information, but I had taken a photo before.

you shold be 290K zise of MEC1663 and you see the HXD the information in the last 2k

Now I have another problem, I already corrected all the information in the T14 bios, but now I have an error at startup (2202: Product Name is Invalid) I tried with lenovo maintenance utility v1.08, 1.11, 1.89 and it is not working, does anyone know how to fix?

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

I don't know this tool, I use rt809h and it works fine, I unlocked a lenovo T14 10th ger with the same technique, T490s has MEC1663 as well as T14. The genuine file extracted from the original lenovo .exe file is 257kb, so you need to remove the first byte to adjust-it.

If you were able to read the file, you can insert it back, as this will reset the MEC password. If not, you will have to insert the file I sent you and use the tool to fix the BIOS information.
