I followed the guides on wii.guide. I ran the DNS exploit to crack the Wii. I don't have an SD card, so I skipped the IOS installs.
Now I'm trying to install cIOS, and when I put my FAT32 formatted USB into the (correct port) on the Wii and open Homebrew, and then select the USB device, I get a DSI Excption...

I tried a different USB externam drive I have (exFAT) - no crash, but cIOS app/installer doesn't show up in the Homebrew menu (nothing shows up). Any ideas?
