Not really sure how you bricked. Can you power on your wii using the wii remote? It could be a blutooth module. Just to confirm:
1) Your dvd light only flashes 1 time during start up and not twice quickly?
2) By holding reset when you power on you cannot access priiloader?
3) About how old is your wii?
You should not have been able to brick by running a game from GX which leads me to think it's a blu tooth burn out.
