My son upgraded his wii to 4.2u and it nolonger played any of the usb loader games I installed. After following several guides, I was able to get the homebrew channel and Boot mii back. But none of my usb loader or some of my homebrew will work. I have uninstalled the ios249 and used dop-ios v8 to work on 4.2u. Everything was installed, yet the games still won't work. I decided to re-update 4.2u after backing my nand to make a fresh start. After the install, I had a black screen appear and the wiimote turns off. The cause of the brick is probably from the boot mii that was installed to boot 2 since I forgot to uninstall it. I've seen a couple of months old threads that posts about this, but nothing recent. If I'm missing something, by all means share your solutions. It would be a big help.
