No you use IOS249 to install the wiiflow Full channel 222 Wad. Always use IOS249 in wad manager to install other wads. Regardless of the wad you are installing. So as long as you installed the 222 version of wiiflow then you are set. If you want themes and covers be sure to download the wiiflow folder and extract directly to your USB Root. then you can place the themes and covers in the appropriate folders or just download them using wiiflow if your wii is online.
