So I did something dumb that I swear I will never do again if I get my card working again.
 
So I have an EVGA RTX 2080 Ti XC GAMING card.
After testing it, I decided to change out the stock cooler and attach an NZXT X62 AIO via the NZXT G12 Kraken mount.
The temps were so good, I decided to see if I could get more performance out of it by switching the BIOS to something that's not nearly as power limited.
I flash the Kingpin XOC bios. That worked fine, but I had to keep my fans a little loud in order to keep the temps where I had them.
So I swapped back to my stock bios. Then I tried to use the GALAX/KFA2 RTX 2080 Ti OC Reference PCB (2x8-Pin) 300W x 127% Power Target BIOS (380W) Official rom found here. I was told by some people in that community that it would work with my card. I think... that might not be the case. But regardless, I also didn't think you could brick a card with a bad ROM flash.


Here's what I got in Nvflash:


 
Flash didn't work... but my 2nd monitor was no longer working. I was told that if it was a bad flash, it was probably still fine because the flash process would just abort. So I restarted my computer, and neither monitor attached to my GPU would work. The only way to get into windows again was to use the onboard HDMI (still using that). When trying to flash my stock rom again (which worked fine when switching back from kingpin), I get he following error:


 
 
I tried uninstalling my drivers and reinstalling... but that didn't seem to do anything. This is what the device manager shows:


 
 
So... did I brick it? 

Boot with a working card and flash the bricked card with nvflash, use -i (--index) switch to flash the correct card.

The Bios may be Official for GALAX Products but it is Not Official for EVGA Products or approved by EVGA to use on their Products.
You need a Valid Driver install to be able to update the Graphics Card Bios.
Maybe Sajin can help you out.
 

 
You Flashed your EVGA RTX 2080 Ti XC GAMING card with the Kingpin XOC bios?
This is not making since now.

Yeah but it still works. I said the same thing to the guys in the Overclock.net Discord who recommended it, and they said it's fine to use it with my card. Can confirm it worked. 

This still applies

Best of luck getting your card back up and running with the correct Bios.

Ok. Dug out my PSU box and grabbed some cables. Put my 1080TI in the first slot. Put my borked 2080TI in 2nd slot. 
Couldn't find TinyLinux. Tried a different version of linux (DSL - Damn Small Linux), but I had problems booting into it. It was complaining about not finding a file system. 
So now I'm trying another version of Linux. It's taking a while to create the bootable flash drive for me. In the meantime... I did this (in windows) since I have a working card in my first slot now:

But  I still get the same error as before. So... I will try again in Linux. Once it's ready. And I learn how to use Linux.

I got Ubuntu. Downloaded the linux version of NVFlash. Extracted it to a folder. Launched the terminal into that directory. But from here, I can't do anything. Not sure if I have to install this thing or what but when I try any of the commands, nothing works. Tried "nvflash" and "nvflash64" as well.
 

 
 

No need to panic yet, there is always hope. I never used any of desktop-y linuxes for nvflash, would still suggest to try TinyLinux. It does not have GUI and much simpler.
 
Also unless your computer is IBM PowerPC, you need to use amd64 or i686 version of nvflash. Don't use ppc64 build, it's not for Intel/AMD CPU.
 
Executing program in linux, if it's not in the path should be done with dot slash first e.g:
$ ./nvflash --index or
$ ./nvflash_linux --list

To flash in a pure DOS evironment, create a bootable flash drive with Rufus using FreeDOS in the Boot selection dropdown and FAT32 as the File system..Leave all other settings at default.

Then add your VBIOS.rom to it..Then add the nvflash and CWSDPMI files for DOS I have here to it.

Then boot from the USB flash drive..You can spam a key like F8 or Esc (varies by mobo/mfgr.) to enter the Boot Device selection after POST, or set it in the BIOS.

Pure DOS has an 8 letter/number filename limitation, so you need to rename your VBIOS.rom to something that has a maximum of 8 letters/numbers before the .rom extension.

You could try nvflash --protectoff then nvflash -f -5 -6 or nvflash -5 -6 or some variation of that command line.

See if flashing in DOS might work for you..Good luck.

That wouldn't work because nvflash that supports RTX Ti is no longer available for DOS.

 
The one on my OneDrive page is NVFlash strictly for DOS and the needed CWSDPMI file to run it..It may or may not work..Just sayin'.
 

The "permission denied" you're getting on linux is probably because you didn't set execute rights on nvflash binary.
 
You need to do a "chmod +x nvflash" to change that (you might have to elevate your rights as root in the terminal by running the "sudo su" command before doing the chmod one).
 
Check results with "ls -l" to display linux rights associated with the nvflash file. There should be "x" displayed in the letters combination shown on the left if execute rights are enabled.
 
But you should cross flash from windows not linux anyway, it'll be easier.
 
Dont forget to right click on nvflash exe after download, then properties and click on "allow" button.
 
Make sure all antiviruses are shutdown as well (including windows defender).
 
Run from a command line prompt with elevated rights: go to task manager then file -> run new task -> "cmd" and check the box "run this task with elevated rights" below.
 
Sometimes the latest version of nvflash can not work properly with your card. Look up what version other people used to flash their 2080Ti and use the same if needed.
 
Also since you're crossflashing, make sure you're flashing to the right video card or you risk bricking the utility vga card as well :)
 
Take your time before flashing, make sure you're using the right command and the right bios file multiples times before you press enter ;)

If your 2080ti needs an emergency flash, you're legally allowed to leave work. Well at least you should be 
 
PS: to download a file on linux use "wget <direct link to file>". Ie: "wget http://uk1-dl.techpowerup.com/files/tzGPZwjVGMOFtW9fWXuBZw/1561382614/nvflash_5.560.0.zip"
 
then "unzip <filename>".
 
But as I said, if you're not familiar with linux stay away from it for flashing. Do it on windows 

Tried a few things (via remote desktop).
 
Tried nvflash 5.513 and 5.527. Still no luck, same error. And yeah, I'm always running the command prompt as admin.
 
The exact command I'm using is:


"nvflash64 --index=1 -6 EVGA2080TiXC.rom"
 
Not sure why, but when I list my adapters, this is what I get from nvflash:
 
<0> GeForce GTX 1080 Ti (10DE,1B06,1043,85EA) H:--:NRM S:00,B:01,D:00,F:00
<1> Graphics Device (10DE,1E07,10DE,12FA) H:--:NRM S:00,B:02,D:00,F:00
 
My 2080TI just shows up as "graphics device." But in the device manager, it does display as a 2080Ti.
 
It's slightly worrying that literally nobody knows what this error I'm getting means.
 
ERROR: PCI Block corrupted 1.OffsetMode is true
 
But maybe only the devs of nvflash would know that?

If you're having flashing issues, I recommend you start Windows in safe mode with command prompt, move to the folder where the vBIOS and Nvflash are located, and run the command to flash nvflash64 -6 filename.rom
 
If that fails a hardware programmer will get the job done easily. 

I have tried this in safe mode. Sadly I don't know any hardware programmers in my area 

When Gaubry was speaking about "hardware programmers", he was refering to what Sajin has linked to, ie "a hardware programmable bios tool", like a usb key ;)

This guy had the same error message that you're getting. He figured out that he was trying to flash a bios that was not compatible with his card.
 
You should make a support request to EVGA, give them the exact serial and product / model number of your card and ask them to send you the correct bios file.
 
Support request form is in my signature 
 
PS: from the nvflash manual you can also try to use "nvflash --index=1 protectoff" before trying to flash.
 
Also use the "--overridesub" parameter when flashing, this could help as well.
 
If you're running Windows x64 (64 bit) instead of x86 (32 bit), dont forget to use nvflash64 instead of nvflash as well.

Even if it works on your cards it doesn't mean it will on his. He could have a different PCB version that is not compatible with it (which was exactly the problem the guy that had the same error ran into in the link i provided earlier) 
 
Seeing he's having trouble flashing i think it's best to ask EVGA for the correct bios file ^^
