Remove Priiloader
Remove Any IOSes above slot 200 (use ATD MOD)
Install clean unpatched IOSes
Update BC & MIOS
Remove & Delete anything else from the console that's nothing to do with or officially endorsed by Nintendo.
And finally... Remove Homebrew Channel & BootMii (do that last)
Edit: ignore everyone else and just do that. As I'm starting to get confused by everyone commenting at once.
Sorry XFlak...
