LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

[Iain21]

Hi,

I need a patched bios for an X1 Yoga 4th gen please. I tried the autopatcher, but laptop just repeatedly beeps with the patched file.

Type: 20QF-00ADUK
Serial: PF-13G9NF

Thank you

Hey there.
I just tried this solution on my Lenovo T480 20L5.
I followed the guide [HOW TO USE PATCH] and after reflashing the original BIOS image, I am back to the Bios Lock.
Am I missing something, I appreciate any suggestion.

Tried it, and its working!!!! Unlocked 3 laptops relly easily if you understand how it works! Thank you for quidance!!!

Many do not understand and brick their PCs
You must read the instructions on the different posts.
This remains a risky method that does not work every time.
Thanks for the feedback

It worked, after flashing it i could access the Bios without being asked for a password.
The only problem is that this is for the IA32 version of the bios instead of the 64 bit version, it won't boot any x86_64 OS.

I tried flashing back the locked one, but the tablet hangs with black screen if i try to open the bios.
At the same time if i try to use WinFlash to force a bios update, with the original one it will freeze at "Reading Current Bios", while with your unlocked one it reboots but the update never happens.

Any idea perhaps?

This is actually solved now after taking a fresh rom from the capsule.
I don't know how to delete the post unfortunately

I am having an issue with the script, it always tells me that there's a dumping error.
I have dumped 4 times with power cycles in between and all the files are (MD5) the same, so i don't think its a bad dump.
Could anyone please check?
The model is a T10 Thinkpad Tablet

Anyone get success with p72 ? gettin 3 beep and no boot after patch
tryin 3 times

I do have ThinkPad P72 (20MB, 20MC) [32MB] in my list of compatible ThinkPad models, meaning that I had patched it myself and confirmed working. I usually patch the earliest BIOS version downloaded from Lenovo website using Serial Number, then I use this patched BIOS Region and replace it in the Original BIOS, doing it this way I virtually eliminated any possible beep codes on patched files. You may have to add some padding at the beginning of the BIOS extracted from BIOS update to match the size of BIOS Region in your Original BIOS.

It's not about the model...
It's about CPU type, if your CPU is i7-8850H then the autopatcher wont work.

Try LPC method described here : https://www.badcaps.net/forum/troubl...ss#post3237235

Good luck!

The LPC approach worked for X1 Yoga 3rd Gen, Type 20LE (i7-8650U CPU). Thanks for the hint!

Hello everyone,

It seems like the issue with black screen and error code 0285 is more common that I thought. Has anyone figure out a way how to get it to work? I'd really appreciate any help.
