After reading MULTIPLE threads here, I've decided to create an easy-to-follow, step-by-step guide to updating to System Menu v4.0. This tutorial uses Waninkoko's "cIOS36 rev.8" and "Firmware Updater 4.0", to guide you through the installation of patched System Menu v4.0 files. Only the required IOS's, Shop Channel, Mii Channel, Photo Channel 1.1, and System Menu 4.0 are installed. The IOS's are Trucha-Patched. To make the process even easier, I have provided download links, to easy-to-use Homebrew Channel apps. **UPDATE** -- My tutorial has now been updated to include "ppc_gba's" IOS60 Patcher. Visit the tutorial HERE. Enjoy!
