Hacking Help with a cIOS

[Metalix]

hi there, i readed a tutorial that says that in order to play guitar hero 5, i need to install the cIOS 55..
so i installed it, but now my wii gives me an error screen that says that the system is damaged..
i need serious help here because the wii is not really mine.

Do you have priiloader installed ? ( HOLD RESET on wii startup )

Do you have bootmii installed ? ( does the disc drive flash twice on Wii startup with no sd card inserted )
