Wii U stuck on "Preparing Update"

[innerglo]

Hey, so for the past few months whenever I try to launch a game while connected to the internet, my Wii U will try to download the update information for that game. However, the game will never update and is stuck on the "Preparing Update" screen forever with the blue throbber just spinning... forever and forever. I know I don't have updates blocked or the update folder deleted, I've checked this. Is my NAND cooked? Am I banned from Nintendo's servers? What's happening and how do I know? I don't have a problem downloading from other sources but it would be nice to not have to...

system setting-console info-recent error (cannot recall exactly but should get you going)
what is the error code?

If you have modded the console then use Wiiuident to check the MLC manufacturer.
