Ok, so I've been poking around with homebrew for a while now, and have just downgraded to 3.2 due to having encountered several apps that I would like to use that require 3.2. I used Tonas AnyRegion Changer to perform the downgrade, and the process seemed to go fine, but when it got done, ARC showed that there was a system menu/region mismatch and it spouted out a couple errors when I exited the program. I rebotted the Wii and everything seems to be ok, and shows that it's 3.2 in the system settings.
I don't like random errors when I do things like this, and even though everything seems to be ok, I'm now worried that there is some deadly bug floating around in my Wii waiting to brick me or some such crap. What I would like to do is completely wipe my Wii, system data and all, and put a fresh 3.2 on. Is this possible? I thought I would ask, since Preloader seems like it could make this sort of thing a reality.
