well..u said u have a black screen when u turn on wii. so um..that must mean that its full bricked. i had that exact same problem with mine and i fixed mine yesterday afternoon with my own ideas. xD sooo..my idea is that u download either link (NTSC) or (PAL) from flux0deamon's "how to unbrick wii" video. once done, if u have preloader, then go to that menu by holding reset when u turn on ur wii. and from there u go to HBC. then u should see the apps that u downloaded from flux0deamon. so u enter both of'em and accept (blah blah blah) and accept for the other one. once finished..u restart ur wii and u will have the system menu up and running. buuuuuuutttt...thats not the end. u only brang it down to a semi-bricked wii. if this worked for u, then i suggest downloading a "CIOS downgrader" to fix the semi-brick problem. so yea..hope i helped. :)

hey, i have some advice for u if ur wii is still bricked.
