I did the Modmii install on 4.1 ... I have a Seagate Freeagent usb drive which works fine. The problem is sometimes when I launch the USB loader, it doesn't get to the CFG screen and instead pushes me back to the Wii system menu. At that point, if I load Hermes uloader, let it tell me there's no WBFS partition (which there is) and then exit from it, I can go back into the CFG loader and it works fine. Anyone have any ideas on what could be causing this/what I can do to correct it?
