I hacked my Wii about 3 years ago, and haven't used it for about 2 years. I am selling it on gumtree now, and am trying to make it as "hack free" as possible. It's on 4.3e, however says there is an update available. I am wondering what I need to do to update it without bricking it, because I know I shouldn't update direct from Nintendo. If anyone could point me in the right direction, it would be appreciated.
