P104-100 Flashing issue

I recently bought EVGA P104-100 4GB cards from EVGA directly. I’m trying to flash the 8GB bios to the card but it just says the following.

=== Flashing card 0 ===
NVIDIA Firmware Update Utility (Version 5.414.0)
Simplified Version For OEM Only
Checking for matches between display adapter(s) and image(s)…

Adapter: P104-100 (10DE,1B87,3842,5183) H:–:NRM S:00,B:0C,D:00,F:00

Nothing changed!
