LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Hello, you also didn't mention that your original BIOS file is corrupted in the ME region, of course it can't work.

I cleaned the Me region from your original file, try these two files.

Good luck ...

Thanks a lot

Finally tried this on my T440p, and it worked like a charm. Used a SOIC8 clip w/ a Raspberry Pi. Only issue now is to remove the logo the previous owner put at the boot screen, I should be safe to update the BIOS as well right?

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Good day, I kindly ask for help from the Lenovo T495 type 20NK pc forum, I dumped the Bios and through your program I generated the PATCHED bin, mounted the W25Q128FW eprom, I turn it on but I only get a black screen and a series of beeps, reinstalling the original bios leaves quietly. Now reading here on the forum I noticed that many complain about this problem, but it seemed to me that two people talking about the T495 have succeeded. Before making other attempts, I would like to understand if anyone has managed to get the PATCHED BIOS to work. Attached I put my original BIOS and the version produced by Tools. Thanks for any help on this.

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

I'm really sorry for my stupid questions but i spent like 1 or 2 hours looking for an answer:
I managed to get a dump of my T570 bios.
I used autopatcher to get a patched version of it.
How the f*ck do I get it flashed back to the notebook?

I used Universal BIOS Backup Toolkit 2.0 to get the backup.
Which software do you recommend to flash the patched BIOS back to the notebook?
Thanks for your time - I really appriciate your help!

Don't waste any more time, there is no software methods for this job. You'll need a programmer to do it. No other options.

Hello. Does this method work with 11th generation intel i3?
I have a Lenovo V14 g3 IAP. There is a Bios password that I don't know.

thanks man. I thought if I can read it I could also just write it back.
Getting an TL866II and solder off the chip is not worth the amount of money/time/risk for my purpose but kind of interesting topic!

You can buy ch341a for this job, it's dirty cheap - a few bucks.

thanks, I've ordered it and will give it a try. As I've seen there is a kind of pliers I could connect to the chip without needing it to unsolder it. I'll let you know.

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Got my ThinkPad X250 supervisor password cleaned, thanks for the app!

I thought my X250 was bricked when I heard 5 beeps at power up(motherboard failure) after flashing the patched BIOS. But it turned out the beep code was 5 short beep [pause] 5 short beep. Which indicates TPM is refusing to power up the laptop, probably due to tampered BIOS.

I redone the patch from Ubuntu and the checksum result is identical to the one generated from Windows so a falsely patched BIOS is ruled out. I almost lost hope as TPM("Security Chip") cannot be deactivated and it was the discrete TPM1.2 instead of PTT. I also tried ME cleaner(+patch) but to no avail, the laptop power button just flashed once then powered off.

Fortunately physical presence for clearing was enabled and Secure Boot was not enabled. I flashed the original locked BIOS and cleared TPM from powershell with clear-tpm -useppi, in hope that the TPM won't complain about the tampered BIOS again.

I flashed the patched BIOS again, then the laptop booted! I just followed the instructions and everything worked as it should. The program did say "TPM certificated changed." before "Turn it off." message. I used a CH341a with a worned out SOIC clip, I had to hold my fingers on the clip all the time when the programming is in progress. At first I used AsProgrammed but it was a hit or miss in my case, then I used Flashrom GUI and all is well.

Your mileage may vary but that's how it worked for me. Hard labor and time consuming but the result is great, saved me $50+ for BIOS unlock service.

I am in the same situation like you up to a point. With patched bios I get Lenovo screen, I press Enter at the ''interrupt start'' message. Then I press F1 to enter setup but I get black screen. I don't have any OS installed on my hard drive, do you have any suggestion?
