My usb port stopped working, and I'm currently on stock ICS. Is it possible to root without a USB connection? There's a method for international GSIIs: http://forum.xda-developers.com/showthread.php?t=1501719, but there's no indication that this works with the I777 stock ICS firmware, and since I can't use Odin in Download mode, I'm somewhat wary about trying anything experimental.
