LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

[charb93]

Hi your machine has a 13th Generation Intel® Core™ i5-1345U vPro® NOT AMD
That means you likely have either a MEC1723/24 SIO/KBC chip (password is there)
Anyawy there's no solution for now don't bother. MEC15XX/MEC17XX are NOT supported yet
The day those EC/KBC chips are supported by any programmer, you can post a dump for unlocking

Thanks a lot for your feedback.
I will wait for a solution future, I hope.

Thank you the community for your help.
Thank you ERRA, thank you Sparo.

Hello, I haven't been able to remove the password from my Lenovo ThinkPad X1 Carbon 5th generation 20 HR.
SN PFOVPF3N
EEPROM 25Q128FVSQ
BIOS: NIMET78W (1.63)
BIOS recovery with NeoProgrammer OK
BIOS patch with your Lenovo AutoPatcher 0.2 program OK
Writing the patch to the EEPROM OK.
The computer starts, the power button is lit, but the screen is black and there's a short 7-note beep music.
Does anyone have any ideas?

Upload original bios file and provide all necessary information as required by the rules.

Hi Your actual S/N is PF0VPF3N (That's a Zero "0", not the letter "O")
Anyway, Try this BIOS file. FIRST flash Type_20HR_BIOS_Ver_163+WinKey and WAIT for your machine to boot
Only then proceed with ALL the AUTO-PATCHER steps using the second file Type_20HR_BIOS_Ver_163_PATCHED
And After the password is removed, flash back (Of course) Type_20HR_BIOS_Ver_163+WinKey again, see if it works

this one can not be done via main bios, you need patch EC (i/o)

For T480 and T480s the patcher tool did not seem to work but I have used the alternative method suggested by MaxPower and shown on YouTube MxP where you short the LPC debug connector during startup- needs patience but works

[ERRA]

For T480 autopatcher tested and works on so many cases, for T480s yes autopatcher don't work

[Shiru1]

try this one

Thanks for trying,
Its not working, stuck at pulling 0.490A for 10minutes straight
I have managed to get to password supervisor with this bios, but typing anything was returning an incorrect password
I feel i am missing something, i dont know whats not working...
Should i solder another chip from a donor board?

update : i tried to solder another chip on the board from a donor and it was stuck at 0.400A.

If your last attached file(s) are working then write this patched content and follow the steps for autopatcher then write back your original (posted) dump.

My both last attached files are working, i have tried the one you made before. it was not working. (stuck on lenovo screen, can't press enter)
Now my pc still boots because i put back original bios before soldering, but i can't program chip anymore, neo programmer / as programmer doesnt detect it on spi nor, but detects as a i2c eprom.

It's a good thing that you made backups...
So find another chip from a donor MB ... any of this type, and write the content in that:

Macronix MX25L128
Winbond W25Q128
Micron N25Q128
EON EN25QH128

I took another chip, and its doing the same exact thing, but now it doesnt boot.
I can't program a chip outside of the mobo.
Maybe something on my motherboard is wrong ?

Hello everyone,
I need your help for my X1 carbon 5th equipped with a Winbond W25Q128FV: after removing the internal battery and CMOS, using a CH341A, I performed several dumps with different software (CH341A ...1.18, NeoPro.....2.1.0.19 and Flashrom Win...V09.9-97).
After making sure that these dumps were identical with HxD, I patched one of them and then flashed it.
At startup, the backlit keyboard lights up and then the power button starts flashing several times before becoming constant again and... nothing else happens: the screen remains unfortunately black, no access to the bios to continue deleting the supervisor password...
Thank you in advance for your help and, please, explain to me where the error(s) committed may come from...

Write this patched dump, follow the steps for autopatcher then write back your original dump.

Dear Stefan Steff,
I am very grateful for the file you sent me: supervisor password removed!
Would you be so kind as to let me know what was wrong with my files?
best regards

I got a X1 Carbon Gen 9 and tried all the steps but without success.
The BIOS IC dump has been made via CH341. Here is the result of your script:

Using UEFIReplace to inject 2 DXE drivers...
[1/2] BootOption (GUID e0746c42-d3f9-4f8b-b211-1410957b9ff5)
[2/2] LenovoTranslateService (GUID 826bcf56-bac4-43f4-8ea1-8cdf0a121abd)
lenovo_biosfile_2.bin is corrupted or does not contain a valid dump.
There was an error... Aborting.

Device info:
System Unit Serial No.: PF3TQ7W3
System Board Serial No.: L2HF26L002B
Board No.: NM-D341
Revision: To be added soon

Any help is appreciated.
Thanks a lot.

Hello,
I think you are mistaken in trying to remove, for your X1 carbon gen 9, the supervisor password like this: the laptop is too recent to auto-patcher.
Look into this method?

You're welcome !
There was nothing wrong with your files...technically...only the BIOS region from your dump was too new...That's all.

[Lornet]

Thank you.
Also, is the fact that "the BIOS region from [my] dump was too new" related to having flashed the bios to its latest version before attempting to delete the supervisor password?
Best regards

[ERRA]

Yes that's why your bios is too 🆕
