So I recently gave away my Wii U to a friend, and it had CBHC on it. He wants to remove all modded data on the Wii U, but I do not have the SD card containing all of the things I needed to run custom data. I've been out of the Wii U hacking scene for a while, so I'm not familiar with doing it myself. I remember using something called MochaCFW, but I do not remember anything else.
