Hello

Sorry for my english, i am from Greece

I am trying to flash new bios on gtx 470 with nvflash dos.
I am typing this command: nvflash -4 -5 -6 bios.rom but it says:
Note: preserving board settings in preservation slot 5
Note: preserving board settings in preservation slot 6
Note: preserving board settings in preservation slot 7
programming error: Invalid offset

Can you help me?

Thanks

I would recommend you make sure to save two copies of your bios (in two different locations) preferably one on your computer and one on a flash drive that's removable

I would recommend that you fill in your system specs as well as provide as much relevant information as possible for those who help

Good luck

As the previous speaker said, make a bunch of back-ups.
Upload your original BIOS with GPU-Z to the TPU database and bookmark the hyperlink.

Regarding the "invalid offset": this indicates that someone tried to modify the BIOS with a hex-editor and used insert instead of replace mode.
You were lucky that NVFlash refused to flash a broken ROM.

Which problems do you have with the original BIOS anyway?

To be fair, "750Ti" requires 2 more chars than "470" ;-)

I have a question that might be useful to original poster as well...are there guides for using NVFlash, or videos? I'm interested in learning how to modify a GTX 1070 bios.
