The shop channel requires an update when I went on. That custom skin made it so I was unable to update my Wii. This meant I couldn't go on the Shop Channel.
I have a problem. I want to update to 4.3U from 4.1U...but I can't. My Wii was once 4.3U but I degraded to 4.1U using that one method. Now I want to transfer most of my stuff to my new Wii U. But I got the custom Mario Skin on my Wii. Is there any way I can revert back to 4.3U?
