So you waited all this time, yet decide to update knowing you can now buy anything you want from the eshop, update your games, play online and even use an ISO loader if you so wish.
I can't understand what you couldn't wait any longer for that required you to update?
Not wanting to risk my personal Wii U, besides I was planning on getting a used Wii U later anyways. Better to hack a used one than the one I know works well.
You guys can ignore this thread now.
