Hey guy's i just bought a used Wii U from a local Goodwill but it still has the original owner account on it with parental controls on it, How can i completely format the system back to default settings. I called Nintendo to see if they could help but all the processes i went through with them didn't work. It seems the system is still on software 4.10u which doesn't have a feature Nintendo needs to reset the account. With the system powered on i can't even access anything as it immediately goes to the user login display with no way around it. What can i do to format the system.
