really need help

okay first things first this happened quite some time ago and ive been trying to fix this for months. i installed every homebrew i could find and added prelaoder with a program called wiihome which gives you an option to go to the homebrew channel or start the wii system menu from startup, but the issue is when i select the ordinary system menu it just resets back to the wiihome screen. this is annoying as i cant access the homebrew channel either as the router i used at the time is now faulty and i cant get into the system menu to set a new access point. im really starting to give up hope here guys im just wondering if i can get some sort of repair shop to reset the original firmware or flash the drive. thanks

I'm sorry, I got kind of lost when reading your post....

What results do you get when you turn on your TV screen?

Why can't you access the Homebrew Channel? You don't need an internet connection for that.
