Hello, New to this. Need some help. 1. Installed homebrew channel and trying to play iso. Gave error saying dvd error 324. I believe i read and i guess i need to downgrade from 3.3u to 3.2. 2. Somehow I changed the region from homebrew and now the screen is flickering when i reset the system. Now it does it everytime i turn it on. Is there a way to fix this besides getting a mod or something? Please help. Thanks.
