It's kinda hard to get a cut and dry answer to this. A couple of weeks ago, I learned how to use the Twilight Hack to run Homebrew Applications. That was on a 3.4U version Wii. It was my friend's and he was stoked about doing it too, so we didn't worry too much about any risk, and it worked fine.
I wanted to do up my girlfriend's Wii too, but she just got it this Christmas, and it is her first console ever. She wants to get a bit more edumacated in the art of video games, maybe catch up a bit on what she's missed during everybody else's childhoods. But she was worried that it would kill it. I mean, my girlfriend WANTS to play video games, I'm sure you all understand why I would want to hack it.
She told me she would let me do it to her Wii if I did two more Wiis. So I did. I did a 3.1U and a 3.2U without any hitches. The requirement was fulfilled, my quest was over and I was a Level 10 Homebrew Enabler. But when I returned, my girlfriend was still worried >.< Her parents did buy it and all, so it would suck if the 4th time around I brick one.
Which leads to the question: What risk does installing the homebrew channel carry? What do you do about official updates? Should she be worried?
I never really got the answers, all the tutorials make it sound very safe, and so far it has been.
Any help would be appreciated.
