My Flint2 (4.5.6) stopped or did not work with Tethering ZTE via USB cable.
Last week was working fine but I can't open the modem page (192.168.0.1)
This USB device had a white solid LED light which means is live and working with the mobile network.
I unplugged this USB device and tested it on PC and working fine.
