I have a 5.3.2 U System with the Mario Kart 8 DLC bundle. I would like to add the DLC with the code that came with the bundle, but I assume this requires accessing the E-shop, which requires updating (which I don't want to do). I noticed Cyan posted a workaround to access the E-shop without updating, but when I try this it tells me I need to link a Nintendo Network ID. When I try to do that it says it needs an update to access online services. This fails since I'm using tubehaxdns and blocking the update servers through my router. So I guess my question is if it's possible to create/link a Nintendo Network ID without updating. I'd like to stay on 5.3.2 for loadiine. I realize you can't use the dlc in loadiine, but I'd like to use it on a normal boot.
