I want flash the bios of the rtx 2060 taked by hp omen 15 for increase voltage, frequencies and performances. Do you think it is possibile without problems? Advices? Many thanks in advance

 

Hi, today I tried to flash a bios from hp Omen 15 using patched version of nvflash. Unfortunately the flashing operation failed, the program did not pass the ID detection. Its happened to anyone?

The procedure that I followed after maked a backup of my actual bios and disabled a card by device section is this:
1 In the folder I have put nvflash patched with a Omen's card bios.
2 after disabled the lockout with command: nvflash64 --protectoff (operation done)
3 I have launched the flash command: nvflash64 -6 new.rom

in the cmd window have had this message:

I think there are some protection or other stuff that block the writing of new bios.
Any help is appreciate thanks

EDIT

After many research on google, have found a command in nvflash for force flash over a different device ID.
Command is: nvflash -4 -5 -6 file.rom

The question is...
In case of brick for any problems, Can I reflash my backup default bios and restore? In case of brick, theorically the intel inbuild graphic must work.. right?
Thanks in advance
