Can't get back to Wii system menu
So I just modded my Wii today. Everything works fine and all, but I can't go back to the Wii menu. It goes to the black screen at says 4.1U and plays SSBB. I read a lot of fourms here but I really couldn't understand what to do. I tried tutorials but all said somethign about it'll brick my wii if I do such and such. I don't know what brick means but it sounds bad, so can anyone help me get back to the Wii system menu? Also I can only really go to other channels if I hold reset before power.
