Installing backup file problem!

[robisgangsta1]

Ok so I had certain parts of the mod GTA Lost Angelz installed and one of the components was the gta3.img file and I also edited some stuff to it using txdworkshop so once I put the modded gta3.img file into the models folder BUT I also saved a backup gta3.img but when I tried to uninstall the mod and put the backup back it doesn't work, like it goes straight back to modded file even though I switched it from modded gta3 to the original file. I know that I switched it because i checked it to see if it was the original by looking at the images on txdworkshop. I have no clue what the problem is like some how the modded file is saved into the game or something idk, I tried to reinstall the game but it still doesn't work. What should I do!?

I would try just deleting the modded gta3.img from your installation folder... Restart your pc then put your old gta3.img in the installation folder and c how that go's . I had the same problem with a enb series i downloaded... But i ended up having to re-install gta
