LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

[dhan]

HELLO,

I have a problem.
I managed to patched the bios, but I accidentally deleted the original bin file.
Is there a way to recover or do a vice versa to undo the patched, to be able to have the original bios.
btw, shift delete was used, the orig bin file is not in the recycle bin.

thank you.
attached the patched bin file.

I searched for t480s unlock but i never came accross this thread. I only found ambiguous posts about whether it requires SVOD or works with ch341a.
Thank you for heads up!

Can someone please confirm if Lenovo X1 Yoga Gen.6 can be unlocked with Autopatcher OR if the password is in EC now and need SVOD tool?

Hello friends. I have two Lenovo Thinkpad X1 Gen 3 20LE-S0HQ0B devices and their bios are encrypted.

I tried to use the autopatch program but it didn't work. Please make a patch to reset the password.

Did you miss anything ? A second bios chip for example.

I read this eprom. I assumed that's what the patch is made from.

This is my second laptop on segoday that i put on my blades . lenovo thinkpad x1 yoga gen 3.
Sending the files of the second laptop that I read and patched . Black screen and not even the lights are on
eprom w25Q128
Can you please see what the problem is?

I have laptops in the same condition . Doesn't respond to power like it's dead
Maybe my steps were not correct : 1.I disconnected the battery
2.Unplugged the bios.
3. I soldered the eeprom chip
4. I read it, saved it and wrote it.
All!!!! It never turned on again

to read eprom I use programmer vvde and proc but maybe I need to use another programmer ch341a
Please give advice on which direction to look for a solution to the problem
Even without eprom computer lit up and turned on, fans were spinning, lights were on but as soon as I installed flashed eprom two computers stopped responding to power "zero reaction". Now even if I solder out the eprom the laptops remain dead.

After Step 7, I was having issues restoring the original bios. I tried another CH341 programmer to no avail. I have blank checked and verify that the chip is identical to the file I am flashing it with. If needed the original bios and the patched bios are below. Also is it possible that I could've damaged the traces with the chip? What happens after flashing would just be a blank screen without sound, just lights and it would boot loop.

Worked perfectly fine on a Lenovo X280 ThinkPad Type 20KE that was updated to the latest (as of today) bios from Lenovo while still locked.
Bios chip was a MX25L12873F
Used CH341a programmer, no 3.3V mod.
AsProgrammer 2.1.0.13 (not sure if links are allowed, so just google it)
Chip desoldered (then resoldered, then desoldered and resoldered again )
