A friend in work asked me to have alook at his son's arcade 360. Apparently he tried to do a dashboard update online, this failed, and now when he tries to go online, it freezes. So I brought it home and thought that I might be able to fix this using a usb drive or hard drive update (he doesn't have a hard drive). But the 360 freezes just before the dashboard loads when any storage device is attached and when I try to do an initial setup, this also freezes the 360. ANy help would be very much appreciated.
