@evserv
You are wrong! It's possible !!

I said correctly, the solution is not freely available
Not only you have a solution for new models, but it does not matter, since for users of this forum there are unlock solutions for new models only through jitag

Re: ThinkPad T14 Supervisor password

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.

How did you do it? Does anyone have the JTag points?

Re: ThinkPad T14 Supervisor password

Hello everyone,

Same here with a T14s Gen1 with a i7-10xxx CPU ... locked with BIOS password.

Any chance someone might share the method on how to remove the supervisor password ?

Thanks

rt809h + read MEC1663 + write MEC1663 after that you will have to fix the bios information.

Hello and thanks for your fast answer

When you say "fix the bios information", I think you mean the fact of having the "model type", "serial number", etc ... being wiped out when the MEC firmware is modified ?

That might be a concern as there might be a lot of informations to fulfill to get the system at the same exact status as it was before.

Should tool "Lenovo Maintenance Utility V2.02" might be of great help in the process ?
Does it allow to read AND write the informations ?

If you have access to the data, it's easier, but if you don't, this information is on the machine itself, the serial number is on the label, the motherboard number is on the board itself.

you lose your info when you flash the "Mec16XXX".

may want to reprogram better before the info!
instead of using the maintenance diskette

give me 2/3 dump for compare

Re: ThinkPad T14 Supervisor password

So just to sum it up and be sure that I've totally understood how these new models are built/working regarding the supervisor password removal :

After reading/writing MEC16xx chip with a blank/empty dump, there are some things that needs to be reconfigured.

Technically, from my understanding, MEC16xx chip contains these informations (nothing else to declare ?) :

• Machine type
• Model Type
• Country code
• S/N / Serial Number
• BIOS/Supervisor password
• Computrace informations maybe ?

While using the Lenovo HMD (Hardware Maintenance Diskette) v1.90, there are ways to fulfill these informations using option 20 or C0 and typing this sequency : 1STTTTMMMMCCSSSSSSSS which is composed of :

• TTTT > Machine type
• MMMM > Model Type
• CC > Country code
• SSSSSSSS > S/N / Serial Number

So chronologically, steps would be :

1. Solder wires on JTAG pins (close to the MEC16xx chip on the motherboard)
2. Write an free from password dump of a MEC16xx chip
3. Boot on the Lenovo HMD (hopefully no BIOS errors will be preventing from booting on an USB stick at that time)
4. Use the option "20" or "C0" to fulfill the informations into the MEC16xx chip memory
5. That's it ?

Am I correct ?
