Going to be copy/paste-ing from a message I recieved.





Big news, a firmware update for the Wii U just dropped that is confirmed to make mods unloadable!



If your wii u is currently online, you're likely already affected.



If your wii u is not connected to the internet or turned off, you have a chance!



To save yourself, you need to unplug your router or get your wii u away from an internet connection, turn the wii u on, go into settings, then internet, then go to connections, click your connection, edit the connection settings, go to the second page, change dns to dont auto obtain, and type this stuff in:



(DNS blocks - set primary as the one closest to you, secondary as the other)



Los Angeles, USA: 168.235.092.108



Alblasserdam, NL: 081.004.127.020



then save, and you should be fine once you reconnect to the internet.
