just passing to say thanks to greywolf and scarletdreamz for all the help and to recommend SetMiiUp for everyone.
SetMiiUP is perfect for noobies and if you follow whats on screen is completely fool proof, doesnt matter if you already softmoded your console before or not.
i have to recognize that when i saw it for the first time i was a little skeptical ("it cant be that easy"), mostly because i had a old, parcial and glitchy mod on the console, but by following the steps of the program everything turned to be ridiculously easy, and like i said before, if i can do it, everyone can.
we all know that some foruns/people thinks that "hacks" need to be some kind of difficult to repel noobies and they frequently asked questions (will it work on a wii with an old mod, lol), so i really thank you scarlet for this software and to make things simple for people like me.
