The guides on here are tried and true. If you follow them to a T they work great. Excuse me for saying this, but it seems as if you are shooting for the answer You want to hear. Oddgriffen was very helpful through my mod. If you are not happy with the mod he is suggesting you can always update to 4.2 through N and start over with one of 4.2 mods on here.
use doggeggs 3.1 - 4.1 guide its simple to follow just read over a couple of times first,
I used this guide from 3.3 and it worked perfectly , i have usb loader gx installed and have no problem playing any games.
U need an internet connection for this guide..
I don't know that I would trust "other forums" I do know that I updated to 4.2 (N's latest attempt at the time for "combatting" the mods) before finding Wiihacks. I found the guide I used very easy to read/install. As levin stated read the guide a few times to be sure you fully understand it. When doing any mod bricking your Wii is a possibility. At least here you know if it happens it is user error and not a corrupt file someone had you use just for amusement.
yeah fair play iv been reading the guide few times some can be a bit hard to understand until u have done it il read it again here and if anything im unsure i ask some1 here thx
