First of all, i'd like to thank anybody who reads this, because I know I´m being a noob. I was in firm 3.3u in my wii, i had HB channel instaled and wad manager, I updated to 4.0 and the 2 are still working. I did the cios stuff before updating(to make the wad maneger work), but i didn't do anything else, i didn't do any of these patches for 4.0, I updated from the wii. Now, my SD card channel don't work with the wads I download and install via the wad manager, and neither with any other channel (like mario kart's). There are some way I can fix this? and just for curiosity, what are "cios"? Because they seem to be important in the "wii hacking". Thanks!
