Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
What I have read on the net and other forums as well as this one leads me to believe that flashing the BIOS isn't even a great idea even if you can get the other pipelines working. The problem with the BIOS update is that it can't successfully update everything in the BIOS. Certain areas of the rom won't be affected. Like the device ID.
So even after the flash the card may still be ID'ed as a Radeon X800Pro. Also it will try to add the drivers for the Rage Theatre chip wich the Pro's don't have. You can ignore this but it's annoying IMO. Finally even if you can get the other 4 pipelines to work that doesn't mean that your card will handle the default XT clock settings for ram and processor.
So personally even if I could unlock the other pipelines and they do function I would rather not flash the BIOS or wait on a hacked BIOS that will set the XT clock speeds or perhaps possibly work more correctly with the Pro version of the card.
