So my Wii recently began displaying graphical related artifacts due to overheating. Common problem. I'm going to send it back into Nintendo. Problem being is that I have it softmodded. I have a good Bootmii NAND backup, so I'm guessing all I have to do is load that up and then uninstall Bootmii and I should be good to go? Maybe reformat the Wii flash afterwards in the Nintendo dashboard? Thanks.
