Easiest way is to disconnect your internet connection (in any manner) so the page will get an error. Then you'll be able to reconnect and reset user data or go to another page.Is there a way to prevent the internet browser from automatically loading the last page you were on? Now everytime I load it tried to load the exploit and it freezes and I have to do a hard reset, and I don't even get the opportunity to delete cookies.
Some was to disconnect:
Change your WiiU wireless setting to use a bogus SSID
Turn off your modem
Turn off your router
Unplug the ethernet between your router and cable modem
Turn off the wireless radio in your router's settings
