Trying to fix this fake GTX 1050 Ti that my cousin bought and he didn't realize it until months later. I'm using a CH341A to read and write to the chip AH1403 - 25Q20BSIG - E50578. I was able to read it by desoldering it off the card because it wouldn't read it otherwise. The CH341A device would disconnect as if something is shorting it. I was able to read the bios chip by setting it to PM25LV512A. I've tried programming other GTS 450 BIOS's but no picture shows up. No corruption no nothing shows up. I have to desolder the chip every time to program it so I don't want to do this too many times. Can someone please modify this bios so it shows as a GTS 450 1GB? I think I made a good backup before I started flashing other roms. Not sure if I'm suppose to erase it before programming it?
