when you do that command it says that the video bios is not identical and the update process has been aborted

I try both of the 1080 amp extreme bios, no difference, same error

with the 1080 amp modded fans + liquid metal paste I am not exceeding 65c even in games that pull 260w, like warframe 4k all high setting

with the 1080 amp dual-fan shroud I was having thermal problem where it went to 70c

I would like to keep my card as close to 49c because pascal gpu downclocks -13mhz everytime it passes 50c (5c increments afterwards)

I am not very familiar with using NVflash, so I may not be of much help, but here is a nice list of all available commands in NVflash:

Use a double dash ("--") to use the longer descriptive version of a command.
Use equals ("=") to specify parameters, with separating commas (",").

-- Sample Usage --
nvflash --index=1 nv30nz.rom

You might want to try removing the write-protect and doing a level 3 override. Although there is no guarantee that either of those will work. I have been doing some research, and apparently Nvidia GPUs have some sort of built in BIOS flashing protection, I have done a lot of BIOS modding on AMD cards, but never on Nvidia. AMD cards do not have such protection, but maybe this BIOS flashing protection is what is blocking you from flashing a BIOS file from another card onto your current card?

If that is truly the case then we will have to put this project on hold as no one has found a way around the Pascal BIOS verification checks yet. They were able to do it for Maxwell, but supposedly Pascal is proving to be a lot tougher to crack.

Lastly, this is a bit off topic, but would you mind sharing some pictures of the mod that you did to your card to improve the cooling? I am very curious as to what it looks like,
