Request & question by n00b: GOP/UEFI N770 TF 2GD5/OC S/N:602-V282-20SB1307058435

Question

New to the forum. I ran into some problems after updating Winodws 8 to 8.1. Seems the UEFI install I did wasn't executed correctly. So, now I have a one-week-old PC sitting here, doing nothing.
Just updated the MoBo BIOS via USB, now trying to figure out how to flash the graphics card.
I made the DOS-bootable USB-stick and used this command:
nvflash /v >rep txt
Graphics card: N770 TF 2GD5/OC
S/N: 602-V282-20SB1307058435

I then used (all commands below taken from rchitype's blog):
nvflash --protectoff
Then:
nvflash –-save  backup rom
I assume I have to use this command with the new ROM you'll hopefully provide me with?
 nvflash --index=1 -4 -5 -6 new rom
From what I understand, I should now be able to use the Windows 8 settings of my MSi motherboard?
Thanks for your trouble!!!

You can backup your old vbios if you want with:  nvflash –-save  backup rom
To flash you have to rename the provided file NV282MH.301 to a .rom extension (e.g. NV282MH.rom)
As you don't want to crossflash or such updating just takes the following:  nvflash NV282MH.rom (in case you renamed file to NV282MH.rom)
