Just tried it on USB only over here and it works, I can't reproduce it. It's not a channel just a forwarder, as long as the path isI grabbed the blue circles one from there and installed it and still nothing, but it will work if i insert and sd card with wiiflow :s
Code:
dev:/apps/wiiflow
Then you can use Wad Manager 1.7 or WiiMod to install the blue circles forwarder.http://wiibrew.org/wiki/IOS58_Installer
