Hey this patch is working perfectly for removing the bios so, I was wondering if I could use this to remove the computrace?
I did try but when I try to patch the file CMD opens and closes right away and shows no sign of completing the process.
Can you help me in this matter please. Thanks

Hi guys i need patched bios for P50s

Try

[Andromedus_81]

Lenovo T495s 20QK
The first try didn't worked out and the bios beeped 5x times (wrong checksum). UEFITool revealed the wrong hash:

FfsParser::checkProtectedRanges: Phoenix protected range [BB0000h:F30000h] hash mismatch, opened image may refuse to boot
RelativeOffset: 00BB0000h Size: 380000h
Hash: 894F0EC4AAE777028ADC60150B10ECE724FC165E6530129DD6B56E45623192E6

With the help of HxD i calculated the SHA256 of above range and replaced the old hash with the new one (search the old hash and replace it with the calculated one with help of HxD). A boot with manipulated checksum and patched BIOS binary worked. Supervisor password was removed. Thank you very much!

Donation incomming (:

EDIT:

Output of patcher:

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)

Looking for volumes to patch...
[1/1] NVRAM_EfiSystemNvDataFvGuid (checksum 2609h):
Found volume at offset 710000h (checksum 91f8h)
Volume checksum does not match... Skipping.

Can anyone help how to generate the sha256 code and how to find the range in the HxD program please. Thank You

Hello,

My laptop is also blocked because I forgot my supervisor password.
It's an AMD P14s gen4 (serial PF54NMJB), I have another copy of exactly the same laptop.

My questions:
- I'm not sure how to dump/flash the bios, is it really a CH341A programmer that should be used?
- is it possible to read the bios of the laptop I know the password for and flash it on my other laptop? (they're exactly the same model).
- if not, what should I do?

Thanks for your help

To flash the bios you need a programmer, not necessarily CH341A.
We do not recommend this because each device has its own DMI and Windown key.

[hach]

Thanks for your feedback, I ordered a CH341A programmer.

Concerning copying the bios from another laptop, I don't have an OEM windows key but serial numbers could be copied....

Would the following procedure work?
- dump the bios on my working laptop
- change the bios password
- dump the bios again
- do a diff to identify the area where the password is stored
- => modify this zone on the blocked laptop
I'm wondering whether there might be checksum or other issues, and if so, whether the autopatcher method might not be simpler.

password is stored in EC
not possible unlock via bios dump for this generation

(edited, sorry I misread the thread)

if my understanding is correct, this means that for this model I need to work on dumping/flashing the EC and not the bios, i.e. with a program other than CH341A.
Can you confirm this?
If so, how do I dump the EC on this model?
