I have a Samsung Galaxy SIII (GT-I9305), and here are my problem(s). It can't be detected by PC via USB (not showing on device manager, odin, kies, not even charging) but it is charging when connected thru a charger. Is the micro-usb port damaged? I don't think so because but it can detect my flash drive via USB OTG. I already tried reinstalling correct drivers, tried different cables, tried different USB port, factory reset both from settings and recovery menu.
How can I fix this?
Also, I'm wondering if I can still attain root access/permission even without USB connection but thru terminal emulator?
