I bought an asus gtx 750 ti 2gb oc for a very cheap price, lower than 20 bucks. The seller told
me that he bought it from aliexpress and had some issues like slowing down the computer's boot time
and also having driver issues also there is an exclamation point when you look at the device manager
and no nvidia control panel. So the first thing that came to my mind is that the guy bought a gpu that has
mining bios in it, and I can fix it by flashing the stock rom in it. Well it didn't work at all,
I tried many bioses and still no luck. I want to point out the path I followed so you can tell me what did
I miss or did wrong.

I have uploaded the images of pcb and screenshot from gpu-z, as you can see gpu-z cannot read everything properly.
in images one of the vram is barely readable, I can say that it is pretty much the same with others
variant number is also barely readable but I can say that it is gm107-400-a2, whenever I try to clean the die it fades more and more.

Motherboard gives 62 postcode at boot
I downloaded the nvflash 5.218, as they were saying best version for maxwell but I tried every version
nevertheless, put the nvflash files in C drive
disabled the gtx 750 ti in device manager
Ran cmd with admin privileges typed cd c:\nvflash then nvflash -6 romfile.rom
enabled gtx 750 ti in device manager then restarted the pc

Please tell me if I done something wrong, if the everything is right then what can I do to resurrect this gpu? Could reballing solve the problem?
