Yes u can flash cwm and install superuser after u have flashed rom... but rom should be custom or deodexed.. hence root wil be open.. if u r using any official rom u wont be able to access root.. so u flash any custom rom to ur fone.. angeeks rom ics is the best rom i have used.. great battery backup.. s3 UI and s3 music player... had grt equalizer settings too.. try it..

go to dev section n download it..
