I am using USB loader GX and I can't seem to get the loader to see the new IOS I though I installed. I first used Pimp My Wii, and went through all the steps to update it. I went to the game I wanted to play, COD Black Ops. Went to settings IOS and chose 250. The game still frezzes on the loading screen. I then manually installed Cios 250 through WAD manager. Still no go. What am I doing wrong?
