LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

[AAAC]

@slushy-dabs0s
Make sure you read post #1 of this thread, specifically the section titled:
[ HOW TO USE THE PATCH ]

[slushy-dabs0s]

Thanks Guys, it worked finally.
Kudos to everyone here, great community.

1) (first power cycle after burning patched bios) i had to wait for laptop to restart a couple of times before the splash screen appeared. F1/Enter keys were not working.
2) Once Lenovo splash screen appeared (where it would get stuck), I had to reboot(second power cycle) and keep pressing F1/Enter even before splash screen could appear (i.e while the screen is black) to get prompted.

For anyone who doesn't have original Bios. you can download original factory bios from this post.

Have you tried to use original bios file and see if the laptop powers on?

Yeah I flashed the original BIOS back and it’s still giving me the musical beeps and nothing on screen. Is there an anti tamper switch on T470s?

If you are using CH341A programmer, that may be the cause of the problem. When you program the BIOS chip, does it end with a successful verification?
How did you check that all 3 (original) files were identical?
I suggest to look for Colibri programmer software, download it and use it for the job. Then use someone elses bios dump from another ThinkPad T470s and programm it just to make sure your ThinkPad still works.

I used AsProgrammer to take the bios backup and compared the 3 backups with hxd. I will try Colibri and report back.

Hello, I've removed bios using Autopatcher on Thinkpad L580. I used CH341a and connected pins directly to the motherboard bios chip. It worked like a charm. Now I'm trying to unlock Thinkpad X1 Carbon 3rd Gen 2015. I bought it recently and found out it was bios locked. I tried using CH341a, and it seems to find something, but both lights on the CH341a controller light up and AsProgrammer cannot find the bios chip model. If I choose the bios chip model manually and read from the chip it gives a bunch of zeros. If anybody can help it would be a big help. Thanks ahead.

Check every connection between programmer and motherboard/chip.
