Okay, so I was talked out of updating from System Menu v4.2 to v4.3, so I just want to update the Shop Channel. Supposedly, the v20 of the Shop Channel uses IOS56 v5662, so I downloaded it from NUSD and installed it. Then, I downloaded Shop Channel v20 from NUSD and tried to install it, but my Shop Channel just stays at v19! It was suggested that I try using DOP-Mii or DOP-Mii Wiibrew Edition. I tried both, and they do not install v20. I've also been told to try DOP-SHOP, but where do I get the latest version? Any help would be greatly appreciated! Somehow, my Mac was screwing with the Shop Channel WAD file. I copied everything to my SD Card using my PC, and everything installed correctly!
