To those who mod: The 5.5.2 update only patches the website hax (I.E. Loadiine, GoogieHax <- unsure about GoogieHax but it is my assumption it is patched). Haxchi and Mocha and all that stuff all still work just fine. Basically this update kills homebrew if you don’t have the channel so things you cant use things like Saviine and FTPiiU. https://smashboards.com/threads/tutorial-installing-offline-smash-wii-u-mods.444527/ I use this.^ I recommend it to everyone. I'f you're using mods, do this just in case Nintendo is pulling the same shit they did with the 3DS and is banning and/or is patching all mod exploits: Go to System Settings. Select Internet. Select ‘Connect to the Internet’. Select ‘Connection List’ in the top right corner, or simple press the X button. Find your connection, it should have Wii U/Wii icons on it, select it. Select ‘Change Settings’. Press the arrow on the right once, you should see ‘DNS‘. Once you select DNS, press ‘Do not auto-obtain’ which will take you to where you can enter 052.040.086.243 for the primary dns and 168.235.092.108 for the secondary dns I'm looking into EVERYTHING I can involving this update and will keep updating this thread.
