Need Help Flashing vBIOS after ERROR 43

[rjgrl]

So I was playing games and suddenly my game froze and after a few seconds, the whole laptop just BSOD and restarts itself. After restart, I noticed the NVidia GPU won't be seen in Task Manager, I opened up Device Manager and saw a triangle with exclamation mark and says something and ERROR 43. I already tried uninstalling and reinstalling drivers, open it it up and disconnecting the battery, and other solution I saw online and none of them worked.

I tried flashing its vBIOS and I still think it didn't work, right now the NVidia GPU has no longer have that triangle exclamation mark in the Device Manager but GPU-Z still can't detect it.

What should I do? Should I try flashing it again until it works? What commands have I been missing?

And also, if you have a GTX 1660 Ti Max-Q laptop that has a working vBIOS, please do send it here and I will try your version of vBIOS.

You could have back up the vbios in the first place. Seems like it could be GPU failure by the look of it

Def gpu crapping out

We don't have a vbios that exactly matches up to that. Being a Mobile it is not worth risking putting another on it.

If it's not a mxm design you are sol, that means replacing the whole mainboard or having the die replaced.

I backed it up but it's still the same, when I flash it back to its original vbios version.

Might be tricky due to it being a laptop don't know if it have igpu or dedicated gpu or both unless there's a few options on the table to rule out the possibilities to see if you can ddu the drivers in safe mode as there might be a conflict in drivers or operating system having a fit with the gpu in question

It has both iGPU and dGPU (R7 4800HS + GTX 1660 Ti Max-Q)

Depends on if its an AMD G Series APU or core i cpu from intel

It an amd laptop must be something in the driver causes the graphic card to corrupt the vbios I have only seeing one in a similar issue a few years back due to conflicts in hardware level. Have you tried updating the latest BIOS on the laptop.

Only VBIOS that is pretty close to yours is below

Asus GTX 1660 Ti Mobile VBIOS

6 GB GDDR6, 1455 MHz GPU, 1500 MHz Memory

www.techpowerup.com

Only different is 175F in the device id not 100% sure if it works on your laptop

Yes, the current BIOS version of the laptop is 300 and it is the latest one.

Right OK that ruled out you need to do nvflash to try and flash the gpu vbios

You might need to use protectoff command so it can flash the vbios

Create the folder in c:/ called nvflash then get the latest nvflash on this website along with the vbios I provided and put them in nvflash folder then rename the vbios TU116.ROM

Then open cmd with admin then type this in as cd c:\nvflash\ this will direct to the required location of nvflash
Then type nvflash64 -6 --protectoff (this to turn off protection in vbios flash)
Then type nvflash64 -6 TU116.rom (this is where flashing the vbios is happening you might have to press Y to continue)
Once done type nvflash64 -6 --protection (this to turn on the vbios protection)
Then reboot to see if the gpu is recoverable

GPU-Z still can't read the GPU.
This is what it's like right now.

EDIT No.1: I found out there is a new hotfix driver update released by NVIDIA recently, I'll try using DDU and use that hotfix driver or use an older version that was released by my manufacturer (ASUS). Fingers crossed and I hope it'll fix this issue.

EDIT No.2: Tried DDU and installing the hotfix driver and old manufacturer's driver, still not working.

The reason it not working is because of the vbios corruption you have to reflash the vbios to the graphic card for it to work again. Reinstalling different drivers won't fix it

I flashed it back to its original vbios which was the one that got issues in the first place, it's still not working.

 

[Edwired]

You have to reflash the vbios like the one I gave you as you generally reflashing the original one with the issues is generally a bad idea

If it don't fix the issue with a different vbios it generally means there's something wrong with the graphic card you will have to send it for motherboard repair or RMA to the place where you got the laptop from

I don't have any warranty left so I think I'll just have to get its motherboard fixed if that's the case. I already tried different GTX 1660 Ti Max-Q vbios but none of them fixed the issue so far.

Dead gpu, time to upgrade

Would reballing/reflowing fix the issue?

No guarantee of that.

Todays mobiles are notorious for cooking the die and vram

 

[rjgrl]

No guarantee of that.

I see.

i flashed my asus laptop vbios with one from techpowerup and was a good idea after my laptop had a region problem wich wasnt the fix but my laptop still keep on working

with mobile vbios

you just have to get a rt809f detect the right chip and wala! you have a default vbios dont forget to get the aligator clips


do hex edit compare the file like said and change anything differerent to the downloaded one from the original
