..reviving an almost 1 years old EoF thread..not really originalI found an easier method, hold L while turning on the Wii U and it will boot a file in the SD card called booty.3dsx and it will instantly launch the Homebrew launcher. From there you can use HaxHax and downgrade for TubeHax but just saying it wont work if you. QUICKLY mtn DEW BEFORE NINTY PATCH
