Download NVFlash. NVFlash os the official NVIDIA utility to flash the graphics card BIOS (firmware) on GeForce RTX 2070, 2080, 2080 Ti, Titan V, GeForce 1080 Ti, 1080, 1070, 1060, 1050 and older cards.

NVFlash is used to update the firmware stored in the EEPROM of an NVIDIA display adapter. It can also be used to perform other tasks on the adapter such as saving a copy of the current firmware image to a file, displaying the version of the firmware image, or determining the EEPROM part present on a display adapter. NVFLASH is a command line utility that can be run standalone from the command prompt, run from batch files, or spawned from other programs.

• Make backups with the following command (in dos): nvflash -b filename.bin 
• Flash your bios with: nvflash -f filename.bin or nvflash filename.bin

Warning
There is a real danger of a display adapter becoming unbootable and thus preventing the entire system from booting if the update process is interrupted due to a software fault, power failure, the operator manually resetting the computer (for example via a reset switch), or the operator updating an adapter with the wrong firmware image. For this reason, care should be taken when using this utility.
