ok..
I bought Band Hero for xmas...I tried to load it and it was not working..I thought it was due to my WII being moded...so I went into my WII system and reformatted it...now all I get when it boots up is the preloader menu....bottom left corner says
IOS V30
Systemmenu v289

in the right corner it shows
preloader v 0.28

Help...how do I get back my WII to the original state?

can you access the wii menu atall? if not its a brick, but dw you have preloader so your easily be able to fix it, however my knowledge on it is a little "weared" so you may need google as you pal.

I can access the homebrew stuff and even change some boot stuff but never back to the wii menu
