So it's not actually fully bricked at all then.
Anything where you can get preloader is not full bricked.
What you have is probably a preloader brick which has been discissed on here, oooh, must be coming close to a thousand times now.
Using wad manager ..
Install IOS60patched IOS60patched.rar
Install Sys Menu 4.0U 4.0U-System menu-NTSC-U-v417.wad
You should have your Wii back but you will then need to reinstall Preloader.
