Will deleting all the content on the Wii U and factory resetting the console force me to update/connect to the internet during setup?
Yeah I just tried to delete all content and it requires an internet connection :/ I'll probably just delete the previous owner's accounts and data thenIt can't make you connect to the internet if you don't have it. Just don't set it up.
When I selected delete everything to system restore the system it attempted to connect to the internet and told me no connection was found, I didn't see an option to system restore without connecting to the internet in generalIf you do a system restore it'll revert back to new, and it won't make you to connect to the internet, but it'll suggest it.
