Hello and a good day, I have a question regarding the T440p/T540p whitelist removal, if I flash the bios with the withlist removed will the TPM module/security chip still work? Can somemone verify this for me please? If u can enable the TPM module/security chip for bitlocker after the bios flash.

 

Thank you very much for your help

Hi! 

For T440p - yes, TPM module/Security chip still works after bios unlock (if you choice unlocking method with creating new digital RSA signature). 

But for T540p and T440s - No.

That is unfortunate, I have a T540p that I wanted to install a Intel AX200, but I need the TPM module to work cause of the place I work mandates this and also some other AMT options, is there any reason the TPM module will not work even after new signage on the bios file with a new RSA keys? I dont need to advanced menu if that is what's causing the problem, I only need the whitelist check switched to 0

Thanks for the info and help

Dear Klem,

I recently acquired a Lenovo T440P, and would appreciate if you could help me get the WLAN whitelist removed, as well as the Advanced Menu unlocked.

I used a SPI programmer CH341A to dump my BIOS from W25Q32.V chip.

Bios Version : 2.54

 

Thanks, and I appreciate any help!

Hello Klem,

I have a T440P, I'm able to read my bios (Winbond 25Q32fVSIQ 1446) but the bin *.file is never the same between a lot of read.

Each time i click on "detect", i have a different id...

How to do? Please help me.

 

Remark: i  downgrade my bios version from 2.54 to 2.35, but always the same problem.

Hello klem.

After a lot of tests, with patience, i have my good dump bios...identical after several read!

My problem was : the test clip must be properly placed on the chip. I used "CH341A v1.18"

When you click on 'detect', you must have the good name of your chip (in my case before this, i had always "?" in the field of chip and it was possible to read the chip BUT i had always a different *.bin!)

Here, is my file, please klem, could you change this to have an "unlocked" chip for my T440P?

Big thanks to a big man;
