Default Lenovo ThinkPad E15 Gen2 need dump

Hello,

E15 Gen 2 (type 20T8, 20T9) Laptop (ThinkPad) - Type 20T8
GE420/GE520 NM-C771 Rev: 1.0

When trying to read the dump accidently pushed erase instead read. So this model dump was lost.. Does somebody have a dump?

Compatible versions:
ThinkPad E14 Gen 2 (type 20T6, 20T7)
ThinkPad E15 Gen 2 (type 20T8, 20T9)

Default Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Hello. I will explain the situation. I got ThinkPad E15 gen2 (nm-771) with supervisor password. Trying to read BIOS dump from eeprom I accidently pushed erase.. so BIOS dump is lost. But I got other dump, what is working on my model. Here I share it. Is it possible to patch it to remove password?
I was trying by self, but patched file is identical to old. I used HxD redactor to compare them..

Hello.
On days finally got SIO programmer and read the firmware from EC. What I should do further?
Briefly remind my problem. I got ThinkPad E15 gen2 (nm-771) with supervisor password.

Update to this post.
So, managed to find working EC dump from off site. It works well, but here is a problem. I also need to copy region with info about serial number to new dump. When I copy this area of code to new dump and turn on laptop, I get this message:
0177. Bad SVP data, stop POST task
Please help me to copy information about serial number to new code.
Here I share EC dump from off site.

Default Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Do admin and supervisor password is the same? I tried other BIOS dump. No changes. I found that supervisor password is in EC chip. I found EC dump on off site and it works, no password anymore, everything is okay. BUT, problem is how to move serial number info from old dump to new.
But thank you. I will write a message to that person, who manages to unlock password.

they are probably AMD, I have an E14 Gen2 AMD, and my original DUMP doesn't contain Intel Engine/Graphics Firmware. But if it's an Intel I have a clean original DUMP.
