LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

[Cunninghood]

This is the patched file using python27.

Could you help me try patching it using your setup? T460.bin is the original file.

your file t460 patched 32 mo
my ori t460 patched 16mo


very weird
I don't understand why your file is 32mb while mine of the same model (t460) is only 16mb

[Cunninghood]

Thank you so much. Yes this is weird, might need knucklegrumble to enlighten

[Cunninghood]

Oh wait, you mean you tried to patch my original file, but it is showing 32mb too right.

Mmmmm.... I tried to patch using manual replacement of "lenovotranslate" and "bootoption", my machine can power on, but there is no display.

[Maxpower3]

yes if I patch your file, it is 32mb.
and if I take one of mine it is 16mb.
you can try my patch file for your machine that should unlock the Password.

there is something else to modify than boot and translate for this model.
nvram must also be cleaned up

[Maxpower3]

read the original several times to be sure of your reading

[Cunninghood]

Thanks for enlightenment

How do I go about clearing the nvram?

[Cunninghood]

Also other than clearing the nvram, what else do I need to do?

[Maxpower3]

you have to compare the files to find out how to patch them.
all the keys are in the patch

[Cunninghood]

If not too tough, can you guide me? If it is a cumbersome process then forget it. Appreciate ur reply

[Maxpower3]

the explanation is in the discussion thread.
look at message # 19 and in other topics like Remove_SMM ... UEFI.

The best learning is to learn and understand on your own

read the topics and come back if you don't understand

I saw the problem, I'm going to look at it, why is it not working

[Knucklegrumble]

Sorry guys I did not have time to look at your files. I'm going to test them and let you know what I come up with as soon as I can.

[Cunninghood]

thank you maxpower and knucklegrumble

[Knucklegrumble]

OK... I found the reason why your file was doubling in size.

I rewrote the cleaning step of the script and modified the process. It should work as intended now.

Tried your script with python 2 give me error, but ok using python 3. i use windows. first attempt with locked spv password X250 success, but i need to press small button on the buttom.

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

If I could have the script press the button for you I would... There are limits to what technology can do for now...
