you have cleaned the security tab.
type supervisor password and power on password
blank twice and save or type a new password
then restore bios

PATCHED nvar - there is an image but it doesn't ask to press esc or spase

this is not the usual patch, no need f1 or space like autopatcher, just nvdata cleaning
wait and try F1

PATCHED - I flashed it, but the password is gone

it will never ask for password again forever

EDIT: If nothing works, read PATCHED after cleaning security and review it for me

type supervisor password and power on password

Hello, I need help. I can't unlock my T480.
Type: 20L6-SDR213
Serial No: PF-14H8HB
The BIOS is locked. I performed two BIOS dumps, and both were verified.
The chip is a W25Q128JVSQ, and I used a CH341A programmer. I then patched it, wrote it to the IC, read it back, and confirmed the file was written correctly.
I proceeded to boot the laptop, but there was no display. The buttons light up, a melody plays through the speakers, and then it shuts down.
I restored the original BIOS, and it locked again, but this time the screen turns on and it prompts for F1.
What could be the issue?

[br1803]

These are dump files of my laptop Lenovo ThinkPad T450 extracted with CH341A programmer with three different softwares.Actually I didn't remember(backup) my mother board s/n,model, it is refurbished laptop, Original screen replaced with LCD screen brightness not working.My new LCD screen arrived lately while I forgot supervisor password.Only i have hard disk password.when I replaced with my old working HDD(now I am using SSD) it struct on boot when click F2, If i press F12 struct on welcome screen,pls find dump attachments,
Sorry for late reply to SMDflea
