Re: please patch this ThinkPad S1 Yoga 12

First of all, thank you so much for figuring this out and sharing the solution!
I used your technique to read and clear the UEFI password of my Yoga 12.

Now for the remaining problem: Even though I can now enter the UEFI by just pressing enter (empty password), I cannot change any settings. I guess this is because the "lock UEFI BIOS settings" option is set to enable. Probably this prevents me from making any changes.

Any thought on how this can be resolved?

EDIT: Nevermind. I repeated all steps from scratch and now it works

Patch possible on yoga 12
Pach by bios, no need to reprogram EC (Kb9022Q)

- Just read the two bios files (8+4MB)
and join them with utility provided.


Use Uefi Tools to modify your BIOS

Extract as is LenovoPasswordCP E4F272DA-237F-454C-8868-FCF096CF1C6C
Search AA382865-12B0-44E5-A731-6DEF4DF34CE7 LenovoPromptService
Replace as is LenovoPromptService by LenovoPasswordCP
LenovoPasswordCP must appear twice after
Split your file, select 8 for first file

Cleaning can help but not necessary
Password CP and Prompt may appear several times in relation to the bios templates, so all of them will need to be replaced

The patch allows you to access setup
- Load by default for the first time and restart
- Enter setup and go security
- type a blank password twice and save.
- Turn off, restore your original bios.

If you don't restore, the password will never be asked again!!
Tested here : https://youtu.be/f43JuDzA3yU

Booting may take time with different melodies, be patient!!
This patch also works on other models
https://www.badcaps.net/forum/troubl...10#post1873410
I'll leave you tested,
No Prompt, No Password
--------------------------------------------------------------------------------------------
For clear EC KB9022Q as previously cited
Just replace 0x200 to 022F on your original EC Dump
no lost UUID ,serial and others numbers

Can someone help me create a patcher with python
because the autopatcher does not extract, just replaces.
I don't understand anything about python
