Hello, I just bought a used Wii U, but when I open the browser it restarts and a screen appears saying iosuhax and then returns to the home screen. Does anyone know how I can remove it? Apparently the old owner had it hacked. Actually i would like to hack it later, but I haven't seen any tutorial or anything yet, I just stumbled upon this problem. The Wii U was formatted when i bought it, and however reformatted it when i first plugged it in. It has v5.5.3 U. I hope you can help me. I was really really excited to start using this baby. Sorry for bad english. And thanks in advance.
