Hello everyone!
I need a bios file for my thinkpad e490 due to a corrupted bios issue caused by resetting nvram in opencore.

Laptop Model: Lenovo ThinkPad E490 20N9
Board Number: FE490/FE590/FE480 NM-B911
REV: 2.0
Bios Chip: Winbond 25Q128JVSQ
Type: 20N9-000DPH
S/N: PF-1DHTNJ

Hi everyone, I've read all the threads before posting, and apologize beforehand for the whole history I'll tell, I just truly hope this amazing community can help me fix my problem.

My BIOS gets corrupted after NVRAM reset on Open Core, I bought the CH341A, made a backup of my dump, and tried to flash with several of the different BIOS posted here, with all of them, I was having the same result:

Power light turns on and off slowly 3 times before staying steady on, no caps locks/tab working, which of course made me settle my mind on think that I burned my motherboard on the process, I leave the laptop "on" overnight blisfully hoping it will work at morning, of course it didnt; HOWEVER, after I pressed the power button to turn it off, it goes through some sort of "reset" where out of nowhere it turn ON! It shows me the lenovo boot, of course show me a CMS error and date/hour wrong, I go inside the BIOS Setup, reset all the values by default, restart, and the same BIOS error was showing, CMS & wrong date/hour, I fix the hour and date, restart, and GO BACK TO SQUARE ONE (Power light turns on and off slowly 3 times before staying steady on, etc).

My first thought was "Ok, let's see my corrupted backup BIOS and compare" But when I opened that file, it was full of FF codes, so either I didn't backup properly or it was not reading the chip at the moment I tried to do the backup.


So I would like to ask you guys what's the best option/solution I should go for it? I thought of buying a fully working and used E490 just to flash their working bios onto mine, but I feel that's basically what I've been trying to do when I flashed the files on this forum.

Thank you so much for taking the time to read and any help/comment will be fully appreciated!


Specs:
Thinkpad E490
Board Number FE490 NS-B911 Rev: 1.0 2018-10-25
BIOS Chip: Winbond 25Q128JVSQ 1912
Type 20N8-000GAD
S/N: PF-1RER6W 19/06

I'll leave attached the BIOS file that's currently flashed. I can also upload my backup, but it will be worthless since it's just filled with FF codes.
