Can't change my GPUs VBIOS :( despite successfull flashing with NVFLASH :(

[Dako88]

I've been trying all the possible ways to change my wrongly named GPU on my MSI laptop from K2 GRID to GTX 870M (as it physically is)... I've managed to use -5 -6 attributes and get a "success" result but after restarting the laptop, the GPU remains GRID K2 and the BIOS remains BAD... how do I FORCE the correct BIOS onto this piece of crap? PLEASE help

What exactly are you trying to acheive cause at this rate you'll brick it, literally just the name Grid K2 to GTX 870m? load the default bios again and pray you havent bricked it already...

I have purchased it this way - it was "stuck" with GRID K2 (no idea how). It's a GTX 870M though... Is there any way to restore it? I've tried the BIOS from MSI support and another one from web - NOTHING changes, it remains as GRID K2... I've uninstalled everything twice The only drivers I can install are K2 GRID drivers, the 870M won't install (unsupported GPU). I can't overwrite the VBIOS I guess to bring it back to stock After all my efforts I've managed to bring back shader values etc to normal but it's still called GRID K2

Does it perform as it should? if so what's the issue, just load the default bios onto it and be thankful you don't have an expensive paperweight on your hands..

I'm not sure why it's being reported as that as it's not a mobile GPU but if it's working and performing as it should I'd leave it well alone and maybe contact MSI or NVIDIA direct to see if they can give you any advice

The drivers are sh*t :/ Furthermore it keeps using the fans like crazy for no reason, without any warming... The temps are low even under OCCT...

Wish I could somehow recover it to normal :/ f**king $3000 laptop with no fan controll whatsoever...

How to recover from a bad video BIOS flash

Almost every day there are new threads regarding bricked graphics cards due to wrong BIOS flashing, and since eidairaman1 is no longer around to help, here is a guide how to deal with a bad VGA BIOS flash. Find the correct BIOS First off, you'll have to find a copy of the original BIOS. In case...

Thank you for the guide, it was quite well written.

Sadly it didn't help - the windows procedure stops with "GPU mismatch" no matter what I do... When I successfully update BIOS with USB DOS starter, it still turns into Nvidia GRID K2 automatically

I wanted to do the 1-8 pin connetion but I have no idea which chip is it...

That sometimes just means the Bios is locked, for example, I got the same message when trying to flash my card when I was using the correct bios for the card, all I wanted to do was increase the power limit, the rev 1 version had a higher limit than the rev 2, same GPU etc, so you may need to "unlock" that Bios, if my memory serves me the command would be nvflash --protectoff

 

[Dako88]

I have managed to unlock the BIOS and flash it many times but it still remains K2 GRID after I restart the PC

 

[pavle]

Did you use modified nvflash that bypasses pesky protection? Anyway here they are. I mostly used v5.265 (x86) and v5.287 (x64) for my GTX 660, 680, 770, 780Ti and 970 cards.

 

[Dako88]

I have just tried all 3 with same result: GPU mismatch... They see my card as a f**king NVIDIA K2 GRID :/

Wish there was a way to ignore GPU mismatch and FORCE a flash...

MAYBE there is a way to EDIT the BIOS Device ID? I've tried a HEX Editor but I can't find and replace the correct line to make them match:

NVIDIA NVFlash with Board Id Mismatch Disabled v5.590.0 Download

This is a patched version of NVIDIA's NVFlash. On Turing cards, NVFlash no longer allows overriding of the "board ID mismatch" message through comm

www.techpowerup.com

use this, alongside with -6 --protectoff commands

btw, -4 -5 -6 commands usualy works just like that to force flash any bios u want inside

nvflash --protectoff
nvflash -4 -5 -6 (bios name).rom

 

[Dako88]

Same result: GPU mismatch

Do you think it is possible that your laptop has a GPU, NVIDIA K2 GRID, then ?

@W1zzard Something fishy going on here, GRID K2 is a discrete dual-GPU server/workstation card, no way you'd find it in a laptop.
