Hacking Wiiflow or any game loader won't start

[OisacX]

Hi guys, I softmoded some wiis out there without any problems, but a guy got back few months laters with a wii that can't start the channel forwaders. Won't start for WiiFlow, USB loader GX or USB configurable. The software starts, but won't show any menu and go back to wii Channels menu. Anyone have any idea how to fix this? I tried reinstalling the iOS but the problem is still there.

Thanks
