Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Hi guys.
I'm struggling here with my Thinkpad X250.
Can't start after last night (apparently updates).
My BIOS is locked and I don't know how to proceed with autopath.
PORAD shows me that it saves the file, but it doesn't save it anywhere.
Can you please help me unlock my BIOS?
Thank you.

Try this file ... build whith AUTO-PATCHER ...

Hello Try this: Are all batteries removed Battery + CMOS

If so, press the power button for more than 10 seconds.

Reset NVRAM

How would the BIOS be read out via clip or chip desoldered.

A picture of the current chip would be helpful.

Check if all capacitors and resistors around the chip are ok.

Not that a resistor was moved when unsoldering.

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Hello to all.
I have Lenovo Thinkpad T470S with Supervisor Password.
Read a lot of the post on here and I'm not sure what to do..

Do I need to remove the bios and put on some programmer to get the bios dump and patch it, then to flash it (as it was written on the post #1) ?

Or should I get a bios dump file with some software then patch it and flash it?

I do not have a hardware programmer, can I use another patched bios file if there's any here available?

So disconnecting the battery didn't help.
The chip was read on the board using the clip.
All resistors seem to be in order.

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

So no matter what I do, the result is still the same.
I unplugged the memory and it doesn't work.
Removed the batteries and it doesn't work.
I only have to beep 5 times 2 times in a row.

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Well
It doesn't work any other way
The advice will beep but it will start soon.
it wanted to set password and id.
But now it only writes ... To interrupt normal startup, press enter.
And nothing

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Whoah.
Everything is in order.
After your edit, I loaded back my original BIOS and it's ok.
It no longer needs a password and runs.
Big thanks.

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Hi all
I bought a Lenovo X390 Yoga (Model 20NQ-S1C400) with unknown Supervisor Password on BIOS.
I was able to read the BIOS dump with a CH341A and autopatched the file.
Unfortunately, the patched BIOS doesn't work. The laptop just keeps beeping at startup and the screen is black.
I repeated dumping the original BIOS and checked that the content of the files is the same. --> The dumped BIOS is correct.

Writing again the original BIOS, the Laptop boots but I'm still not able to enter BIOS (because of the Supervisor Password).

Here's the output of the autopatcher:

autopatch "C:\Users\...\original_bios.bin"

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):
Not found... Skipping.

Done.

PATCH FILE: original_bios_PATCHED.bin

Good luck.



Can anyone help me?
What means the constant beeping at startup with the patched BIOS? Is the CRC wrong?

Thanks in advance.

Hi all
I bought a Lenovo X390 Yoga (Model 20NQ-S1C400 with i7 8th generation CPU) with unknown Supervisor Password on BIOS.
I was able to read the BIOS dump with a CH341A and autopatched the file (https://www.badcaps.net/forum/showthread.php?t=87588).
Unfortunately, the autopatched BIOS doesn't work. The laptop just keeps beeping at startup and the screen is black.
I repeated dumping the original BIOS and double checked that the content of the files is the same. --> The dumped BIOS is correct.

Writing again the original BIOS, the Laptop boots but I'm still not able to enter BIOS (because of the Supervisor Password).

The BIOS chip is MX25L25673G
The sticker on the mainboard indicates WKS FRU: 02HM794
It's a 8th generation i7 Intel CPU inside

Can anyone help me and remove the BIOS Supervisor Password?

Thanks in advance.

Sorry this will not work Yoga X380 yes AUTO-Patcher Yoga X390 no.

Only goes from the 4th to the 8th Intel generation.

The BIOS will have a self-healing function because of the beebs only.
