I have a 4.0U that is modded right now, but it's completely screwed up and I was thinking of just following the guide that's stickied in this sub forum to remod it. Would it be safe to follow this guide: http://gbatemp.net/t171901-modify-any-wii-4-2-below and upgrade my modded 4.0U to the official 4.2, then proceed as normal? As a background... my 4.0U was working fine, but I accidentally changed SD cards and USB Loader got messed up. Everytime I load it, it tells me to choose either IOS 249 or IOS (forgot the number). I'm not sure how to find a fix for it, so my goal is to just remod the entire thing all over again.
