Moved to the bricked section, as you most certainly have bricked your Wii by removing the IOS SM 4.0 runs off of. If you have BootMii installed as boot2, you can recover. Failing that, you might want to consult some of the threads in this section. Usually folks like mauifrog will offer their advice as to any possibility to recovery. As with everything, give him or others time. Wish you luck --- you've learned the hard way why we say never, ever uninstall an IOS below 200. Wish you luck.
