its called Softmod 4.3 Wiis guide.
your loader channels will be useless until you are resoftmodded again. (the update killed it like the hbc)
you need lego indiana jones or the yu-gi-oh 5d original game to get your softmod back.
a downgrade to 4.1 is recommended too, you'll get priiloader alongside with the guide to stop further updating actions on your console.
