LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

[Drta]

Hello everyone!

In the past several weeks I've learned a lot from this forum and its community especially from all the folks who contributed to THIS thread

With some trial and error I was able to reliably patch BIOS dumps for SVP-locked Lenovo machines up to the 8th generation using the info, tools, and files provided on this forum. After some practice and positive feedback from users I helped I've noticed that, once learned, the process is fairly straightforward, so I've developed a small python script to automate it and allow everyone to patch their own binaries without having to ask for help and wait.

WORKS ON T540P, you just have to flash the 4MB chip. Thank you for this tool.

Because your clip is bad. Desoldering and write on programmer it's 100% safe!

I managed to desolder and program the original BIOS onto the chip. It worked fine. I verified it twice and everything was correct. However, after soldering it back onto the board, it no longer turns on. The power button flashes three times, and that's it.

I have used the autopatcher successfully many times in the past, but this time, with a P52s (20LB), I’m having a problem. As usual, I read out the BIOS and patched it using the autopatch script. No error message appeared. After flashing the patched BIOS, the laptop booted up, but after a while an error beep sounded. The Lenovo Diagnostics app identified the beep code as 010225. Google didn’t have much information about this error. To be on the safe side, I swapped the RAM module, but without success. Then, just to be sure, I flashed the original BIOS. The laptop booted up normally, just with a password. After that, I went through the whole procedure again, but in the end, the beep code appeared once more. What could be the reason for this?

I am offered to buy a Thinkpad T580 notebook with a bios lock. Can the xyz80 generation of Thinkpads be unlocked with the autopatcher method?

There's a search function here. I think there are enough patches for this model to confirm.

Hi FIRST flash Type_20NJ_20NK+WinKey.rar and WAIT for your machine to boot
Only then proceed with the following steps in the correct order

1- Now Flash Type_20NJ_20NK+WinKey_PATCHED.rar
1- Boot the machine and Press ENTER/F1/etc. to enter BIOS settings
2- Enter any character when asked for Supervisor Password
3- Press enter when it shows Hardware ID
4- Press space bar 2x when asked and then Turn off machine
6- Flash back Type_20NJ_20NK+WinKey.rar
7- Reset BIOS settings to factory default
