Just bought a wiiu but there are two accounts from the previous owners i can't delete because they are nnid password protected. Now i want to restore factory settings but it forces me to connect to the internet! If i set up my WiFi to restore the factory settings will my console get updated? I have 5.1.1 atm and want to stay there for homebrew. Or is it safe to update anyway? Hope someone can give me answers here. Thx!
