I don't wan't to hack my wii u... I wan't to fix the update issue on my wii. I cannot connect to the wii shop because it asks me for an update I already have (4.3U). I want to know step by step what should I do to be able to connect my wii to the shop and to be able to download the transfer system thing.
Sorry, but I can't help on it. I only give advice on first-hand knowledge, and I haven't hacked my wiiu (I already have a hacked wii that works, and don't want to void the warranty right now).
