Easy NVFlash Guide with Pictures for GTX 970/980

Step 1:
Download the latest NVFlash from the following link: https://www.overclock.net/t/1521334/official-nvflash-with-certificate-checks-bypassed-for-gtx-970-980

Step 2:
Create a folder called nvflash on your C: drive or whatever your root drive letter is.



Step 3:
Extract the files from the nvflash zip file into the nvflash folder that you created.



Step 4:
Place your bios file into the nvflash folder.



Step 5:
Open the device manager by typing "device manager" into the start menu, and then click "Device Manager".



Step 6:
Disable your display driver by right clicking your display adapter in the device manager and clicking "Disable".



Step 7:
Open the Command Prompt as an administrator by typing "cmd" into the start menu and then right-clicking it and clicking "Run as administrator".



Step 8:
Navigate to the nvflash folder that you created by typing the following into the command prompt, and then press enter:
cd C:\nvflash



Step 9:
Type the following (for single GPU configurations) into the command prompt and then press enter (replace ROM_NAME with the name of your bios file):
nvflash -6 ROM_NAME.rom



If you have multiple dedicated GPU's installed, then type the following (First type nvflash --list to find your device index, and then change the index number to whatever card you want to flash to):
nvflash --index=0 -6 ROM_NAME.rom





Step 10:
NVFlash will ask if you want to continue two times. Type "y" both times. Wait for it to flash (If your flash fails in the middle of flashing DO NOT restart your computer. Keep trying to re-flash until you get a successful flash). When it is done, type the following into the command prompt and then press enter:
exit

Step 11:
Re-enable your display driver by right clicking your display adapter in the device manager and clicking "Enable".



Step 12:
Reboot your computer and that's it!

There is so much info on the net about this stuff. Why in the world would you think that I would copy your shoddy guide for this. LMAO

EDIT: I see that you adjusted your flash guide to be more detailed like mine. Nice. As long as it helps more people I don't care.

Having a bit of an issue at the cmd portion.

When I type nvflash --list, it says there are no nvidia display adapters.

I extracted the nvflash.zip to my desktop --> cmd --> cd C:\Users\Name\Desktop\nvflash_windows_5.165

This happens with display drivers disabled and enabled.

EDIT: Removed my version of NVFlash and re-unzipped.

Didn't see the link to the validated version.

Everything went well, thanks!


Try a thing you haven’t done three times. Once, to get over the fear of doing it. Twice, to learn how to do it. And a third time, to figure out whether you like it or not.

why is it that we have to disable the display driver before starting the flash?

is it a safety precaution?

or is it required, as in it would not work otherwise?

should i disable the iGPU on my Haswell CPU from BIOS before flashing, just in case? or nvflash would only see the NVidia cards, so it does not matter?
