You basically ran inton the same problem my sister had. You didnt brick your console, ill start by saying that. You shouldnt have ran the disc update though because you just load your softmods and will need to do that all over again. My sister (who doesnt mod her system at all) had a problem where she unplugged her console to move it to another TV but when she plugged it back in, she had no light, no power, no nothing. I told her to leave it unplugged for a few hours and then try again and it worked. Give that a try. The problem with neogamma is what I said above. Running a disc update (same region as your console) wont brick the wii BUT if will mess up your softmods. It might not mess everything up but basically youll need to redue everything that doesnt work right. You still have neogamma but you cant actually use it. So you would need to reinstall all your cios. Another thing that happened is you went from one system menu to another. 3.3 firmware uses a different ios than 4.1 as 4.2 uses a different one also. So its very possible that you would need to completly rehack the console using a guide made for 4.1.
