Thanks to the work and effort of GBAtemp's users [Only registered and activated users can see links. ], [Only registered and activated users can see links. ] and [Only registered and activated users can see links. ], a new browser hack is now available for WiiU on firmware v5.5.2.

This v5.5.2 browser hack is still in development and may not be very stable yet, but users successfully used it to get access to available WiiU homebrew.
In its current state, you should use it to install other, more stable and persistent homebrew entry point such as [Only registered and activated users can see links. ] or [Only registered and activated users can see links. ].
