I've messe dwith my wii a lot over the past few months, and something has gone wrong somewhere. One of my main problems is that ftpii and the homebrew browser (as examples) extremely rarely manage to initialise the network, and I also have a number of problems with other homebrew software. I think my problem is that I made a few mistakes previously and modified the wrong IOSs and CIOS's. Anyway, what I'm looking to do is reload a totally legit Nintendo system (4.1 or below) I'm currently on 4.1. I would need to back up save files and miis. After that I can go through the process of hacking again using bannerbomb. Any help on either of the 2 issues (backing up and loading legit nintendo firmware) much appreciated.
