LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

[Alex de Sousa]

X1 Carbon Gen 6 is Intel 8th gen, so autopatcher not works, you must go with the EC method : https://www.badcaps.net/forum/troubl...-ec-pwd-bypass

I just wanted to say thanks, as in the end this is indeed what I had to do. I had quite the journey with mine though. For a start, the shorting process on an X1C6 is pretty timing sensitive, so it took many attempts. Then once I was able to reset the passwords, I got an error relating to the serial number having been cleared. I got around that using the LenovoUOne tool available somewhere on github. After that, my laptop went into a reboot cycling with the dreaded "Configuration Changed" message. I couldn't get into the BIOS and couldn't flash a new BIOS using a bootable USB stick. Eventually, I was able to use the LenovoUOne bootable USB to get into the BIOS and turned off "secure boot" and reset the keys to factory defaults. After this, everything worked, I shoved a new NVME in and have loaded Windows.

I've seen other people having some of the problems I mention above, so hopefully this helps them a bit.

It is working nice on T470S. But i noticed a few detils. 1-motherboard on T470s has 8 gb ddr4 mounted on it and if we taking out non-fixed module, we can test without it. 2-python must be version above 3 and installed with checked "path..." 3-it would be good if bios.bin file be placed in the same folder as autopatcher.exe file. 4-when we programmed bios chip with pached file, first run of laptop maybe will late. It will be start emidietly when you connect source of power (charger or battery). Be patient and dont panic. Several times it will restart himself.

Hey,

So i've tried to do the patch on my T480 and followed THIS tutorial. But once I applied the Patch to the EEPROM, the Laptop won't boot and would only play this annoying melody. I also didn't fry the Chip, cause I now applied the old dump onto the chip and everything is back to normal. I put my dump files in the attachment, both old and patched. I'd really REALLY appreciate some help on that!!!! )))

Patching was successful (both steps) or only a very fast command screen appeared?

Nothing appeared. After I loaded the Patch it just startet and stayed in Black Screen until a melody started.

I mean when you dragged you bios dump on python file to get patched.
You saw a command screen performing two steps or nothing?

Yep, Step one and two got performed and no Error was thrown :/

Then wait for someone to fix it, no big problem.

Hello to all the geniuses out there

I need some help with a Lenovo Thinkpad Yoga X1 Gen 1.

I can't find the serial number on it.

The bios is corrupted i think, when i start it's just a black screen and not caps lock light or anything.

Can anyone fix the bios dump for me so i can reprogram it?

Thanks!

Hello
Have you tried cmos reset?
Remove power adapter, disconnect main battery, disconnect cmos battery and hold power button for 30 seconds, then connect power adapter and wait 3 minutes.

Yes. I have tried that. Didn’t work.

I found someone’s dump on here and tried that and that finally came up with Lenovo logo and tells me to press F1 but when I do nothing happens. Says press enter and I press that and nothing happens. I need my bios dump fixed because from what I read I have to have the original dump back on in order for it to work? But my dump is messed up. Must have done a bios update and crashed mid update. Bricked bios maybe? Any solution?

Where would it be located? There’s no sticker with serial number on it. Can’t figure out where it is on the board either.

I uploaded photos in post 3474. That’s all I got.

Try other dumps...
The DMI data is stored in EC chip so a clean ME and new BIOS will do the job.
BTW your posted dump serial and type (Serial R90ML8P7 and model 20FRS2KG00) does not match the picture...
