Alright, I had cIOS 249 rev7 installed on my Wii before the 4.0 update. I did a normal one, and was still able to run Gamma. I later updated it to rev9, and all went well. No brick, things still operated normally (Including Gamma.) Then I tried using both USBLoader 1.4 and USBLoader GX. In both cases, I can start the installation (USB Drives, External HDDs, and SD Cards) but then I get a DSI Exception, leading to a crash. I later tried to run the rev10 updater, using a network connection, but I got the same problem. I'd like to NOT downgrade my IOS's or anything along those lines, considering I already have a cIOS. My Wii is not an LU64, obviously.
