BRICKED ZOTAC En1080k GPU - NEED HELP

Hey guys I ve registered here because I ve seen some people own en1080k’s . I need some help , I kept flashing bioses trying to unlock TDP control , and now I can’t flash back the original bios because I’m getting GPU MISMATCH error.
Yes I tried the patched version of nvflash , the certificate bypass thingie and its still not working.
Unfortunately I didnt save the original version I got it from techpowerup , so if someone can upload the original bios of 1080 from en1080k and can offer me some advices how to flash it , i d really apreciate it.
thank you
