Hello BIOS masters, please I request your help again. If someone could help me out I would really appreciate it! Please find the details below:

Model: Lenovo ideapad 5-14ALC05 (Type 82LM)
Serial: MPP21Q8VN
Motherboard: FLMA0 LA-01 (Rev 3.0)

Checked the serial number again, it leads nowhere.

Thanks for the answer, but I still don't understand where I can find this file CopyDMI.mps

DMI : 5EA000h-------> 5EA3FFh

And choose in NeuProgrammer this chip: "W25Q128FW"
Because i cannot find "74W12JWSIQ" in the list.

1st you have to read your bios chipset even it is faulty and post the backup here.

Ok, when i write after that an bios file from here, i get an error with the serial number and windows license right?
is this old procedure maybe possible? https://forums.lenovo.com/t5/Lenovo-...3208?page=1

You mean this right? https://www.amazon.de/EEPROM-Program...1&gad_source=1

[paddymoney]

yep, you also need 1.8V adapter. Use ASProgrammer or NeoProgrammer for CH341A and read chipset 3-4 times and compare results with HxD (Analyze tab). When you have 2 identical reads it means you have a good backup.
