Well, as the thread title says, I need to send my WiiU to Nintendo for repairs. I had the basic homebrew stuff installed (homebrew channel, and the necessary cios to play emulators and usb loaders). So, as the problem seems to be a hard drive issue, I previously formatted the wiiU to try to fix it, and it seems that it erased all homebrew stuff, as the "virtual wii" is acting like normal again and there isn't any saved data of homebrew stuff. My question here is... Will nintendo be able to tell that I had homebrew installed? If that's not the case, how do you recommend me to proceed? Thanks in advance. Have a good say!
