did you install the backuplauncher cios ??
It should be in your apps folder as cios installer it might have a pic of sonic in homebrew channel if its the same tut i used to update to 4.1
what tutorial was it ? just curious
just uninstall ios 249 using anytitle deleter (be careful) and then reinstall cios rev14 using wad installation. should work.
i had the same problem and i agee with thetasigma :) not that i have to worry anymore seeing so i have the black screen of death :( Be very vey carefull when doing this stuff with your wii. Im young but i would class mysel as a competent wii "hacker" well installer lol and i even stuffed it up by doing one little thing.
