Here is your new file, it's a virgin BIOS from Lenovo with your DMI.
This file should works fine.

I'll try it though, the bios file that I download from lenovo is dvcn34 not 28

im using neo programmer it doesnt work it sais ic not responding ps im not using a 1.8 volt adapter ,the chip works it has 1.8volt from the battery

34 and 28 is just the version so don't worry.

You have to use a 1.8v adapter if your chip needs 1.8v supply for sure. Also you have to choose verify after programming the chip to be sure that the written file is identical with your opened file.

I bought a 1.8V adapter, but when I try to do detect or write, it says:
Verify memory...
Verification error on address: 00000000
Execution time: 00:00:00.

I'm using the clip, and I don't think there are any connection issues. I'm using AsProgrammer, but I have problems even with other software, and the detect function doesn't work. However, I can read and verify, it lets me do that. Any suggestions?

Hello
Thank you!
But it's not working.
I'm having a problem with this EEPROM
Winbond 25Q64JWSIQ

It's the third LENOVO laptop with this chip that I've tried to write and it fails.
There are some hexadecimal blocks that are different after erasing/writing/checking.

I use a EZP2023+ programmer
He recognizes the chip and reads it.
I've tried different write speeds, it's always the same blocks in error.
I don't have this problem with other laptop models

Do you have any idea where the problem may come from?

The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..

Hi everyone,

I have a Lenovo V15-IGL laptop that originally had a BIOS password. I wasn’t able to reset it, so I flashed the BIOS using this file:
👉 https://www.badcaps.net/filedata/fetch?id=2082788

After flashing, the BIOS password issue is gone, but now:

• The serial number and other system info appear incorrect or missing.
• It's asking for an HDD password, and I can’t access the drive.

Laptop Details:

• Model: Lenovo V15-IGL
• Model Name: 82C3
• Serial Number: PF386JZ
• Motherboard: REV: 1.0 NM-D201 GV452/GV552 (2019-12-27)

HDD Details:

• Brand: Seagate
• Model: ST1000LM035 (1TB)
• Serial Number: WKPT1BC6

I’ve uploaded the backup file — could the password or system info be inside it?

Any help or advice would be greatly appreciated.

Thanks in advance!

post merged..next time look for a thread with the name and model, motherboard model of the laptop, and post there, if you can't find it, then make a new thread..

Don't post pictures unless asked...

Hello, I have the old bin file with the correct DMI data and a second DMI that corresponds to the most recent one on the manufacturer's website. However, I can't copy the DMI from the old one to the new one. It seems to be XOR encoded. When I copy with HxD, the laptop boots, but the BIOS shows "INVALID" in the serial number, etc. How do I edit it correctly? Is there more than just behind LENV blocks? I'd like to be able to do it.

post S/N, full name and model, motherboard model,TYPE,etc.
post the original contents of the bios chip..

Its Lenovo V15-IGL

I managed it. After trying it manually many times, I found the Lenovo DMI Decryptor. It finally worked. Now I'm happy😅. Thanks to everyone. A really great community.
