IdeaPad 3 14ADA05/15ADA05/17ADA05 Lenovo V14-ADA/V15-ADA Bios

[warback-2008]

I have a customer who has a password on his Lenovo IdeaPad 3 17ADA05, model name 81W2, SN: PF2T622M, MTM: 81W20059FR, factory id JVHFC1, MO: PF9XB1628006. He doesn't know what it is anymore. I extracted the BIOS with neoprogrammer but I don't know where to remove the password. The forum is in English and difficult for me to understand. If someone can explain it to me, tell me if it's possible or how to do it? I'm attaching the BIOS which is functional but blocked by the password. Thank you

On neoprogrammer, it gives me: W25Q64FW [1.8V], SPI NOR 25xx, 64 Mbits, WINBOND

Okay, thanks. I have to inject the BIOS from post #14 instead of mine, is that it?

[m1ch43lzm]

Yes, use post 12 or 14 and copy/paste write your DMI from 1000-2FFF from your BIOS to the clean BIOS

Here it is anyway

Try

I'm Sorry, for my late report...by the way, thanks for help...My Lenovo problem, caused by NVME storage, not bios dump issues.

Thank You very much.

Hello.
After updating my laptop Lenovo 15ADA05 to 8CN41WW it started to throw BSOD with clock_watchdog_timeout_error and F2 to enter BIOS is not working
I tried preparing my dowgraded newbios.bin with DMICOPY but AsProgrammer says "File size larger than IC size"
Can you help me preparing a BIOS file to upload via AsProgrammer?
