LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Hi Knucklegrumble,

It worked on the old laptop, but I tried on another laptop, also T460, and it couldnt work again

I manually patched it already.

However, if you are interested, I have attached the bios dump of the new laptop.

That being said, really appreciate your automated file! It really saves alot of time and effort

Ok so it worked on the old T460, but not on a different new T460?

1. Have you flashed the same patched bios (from the first laptop) to both?
2. What happens when you power on the one that doesn't work?

Hey Knucklegrumble,

So sorry, I made a mistake. I replaced the folder, so there were unnecessary files inside. I later deleted the folder and re-extracted again, everything is working. Owe u a treat if you ever come to Singapore!

As far as I understand you can't replace the DXE drivers simply with an hex editor. UEFITool (NOT UEFITool NE!) rebuilds the image fixing the addresses of all of the drivers as they shift up or down when they are replaced.

So to answer your question, they are not similar because UEFITool rebuilds the image and fixes it and you, probably, do not.

ALSO, When you replace, if you are using the drivers I included in the auto-patcher, you need to "Replace as is...", not just the body.

Hello everybody.

Sorry for a lame question, but could you share (a link or manual) how to dump my original bios image?

Thanks.

I'd suggest googling "read bios chip with programmer"

NOTE: The latest version of the auto-patcher requires Python 3. It will not work with Python 2

Thank you for the answer!
For some reason I thought that it should be easy one with some software dumper.

I'm not sure if there is a good reason to buy programmer/solder to chip just for 1 laptop, It's my personal PC, I bought it from hands, it was already used, and only after 1 year I checked the bios and it is locked.

So maybe here is someone from Russia, Moscow who can do this operation?

I patched my original BIOS (x1 Carbon 2nd Gen). Scheme: MX 25L12873F. After reboot I listen 5 beeps and 5 beeps again. After that I see the string "Press Enter to interrupt a normal boot order" or similiar. And that's all. Please recommend me actions for recover my laptop.
