So I updated my Wii to 4.2 and my Wii is getting this error message "Wii System Files are Corrupted" and its just hanging on a black and white screen, freezing, crashing and having issues connecting to Nintendo Wifi when my internet works perfectly. I used to have the Homebrew Channel on my Wii about a year ago or so and just didn't see the point in it and got rid of it. My question is did I though, eventhough I no longer have the Twilight hack save, the Homebrew Channel or any of that stuff is it possible for Nintendo to detect "traces" of it on my system? I only ask cause I just setup a repair through them for free and when I get the system back I am supposed to get an extended 1 year warranty. Now I am really paranoid to send the system in fearing they may find out that my system was soft modded at one point and decide to charge me $85 after I send it in. What usually happens when you send a Wii in that was homebrewed? If you don't have any save files or the HBC Channel on there can they somehow tap into the system and find traces? Any help would be much appreciated, I am probably going to still send it into the New York Repair Center. I also have no desire to ever have HBC again I just want to know if Nintendo can find out if I once had HBC if the channel and files aren't viewable in the Wii System Menu/settings?
