Sounds like you are trying the infamous "cheery-picking" method of Wii Modding, which is a recipe for failure (which is why you are here).
We recommend that you follow our Softmod Any Wii guide from the top and follow it exactly. When you get to chapter 2, include the "optional" (it says it is, I'm telling you to do it anyway) IOS Update pack, in case you messed up the main system, this will repair it.
At the end, see if things start to work. If not, come back and let us know what it is doing now.
