Umm, I can... but I won't. I do repairs. I don't install software for people. Not as if it is hard, actually it is ridiculously easy. As long as you use ModMii then you can not mess it up.
And personally, I prefer wiiflow.
As is, $30 for the repair is too good of a price. I don't need to take my time dinkering around with other stuff. I get paid to do repairs, not to install software.
