@TheCM - Thanks. - No Nvidia vBIOS inside that BIOS. Here please test - Wait, what size is your main BIOS chip?
Ahh, there’s the issue with your test, your BIOS chip is not large enough to hold this BIOS, so only half would be programmed in anyway, so nothing we can do now 
If you know how to solder to remove and replace BIOS chip, then you can solder in 16MB chip, then we can test some BIOS test files, but it may all be for nothing so kinda risky. It may be best to RMA at this point
Yes, that is why I’ve been saying this all along, about GP106/GP107 etc.
Yes, hot air station and bottom heating plate, it could be done with heatgun if you’ve done it 100’s of times and know what you are doing, but I’d never suggest that even to someone that knows what they are doing.
For someone without past experience doing this many times, and having the correct tools, even if you got it off with heatgun safely and did not melt/burn anything and didn’t rip out traces, you’d never be able to properly solder new chip back into place properly.
Really, this is not an option for general person to do, you need correct setup and lots of experience.
Can’t see image, please take a few from different angles and put in zip. I’m not caring about how the chip looks here, I’m interested in the solder work and what’s underneath that, how the pads look etc.
