Enable tethering on G3

Works great

What you'll need:
Root
Root explorer (or something similar)
SQLite editor

1. Activate the hot spot initially in the user interface settings, once it rejects to turn on the hotspot.

2. In root explorer goto data>data>com.android.provider.settings>system>databases>settings.db>systen

3. Press search button then type tether

4. Tap on tether_entitlement_check_state goto the value and edit to 0. Save then reboot phone.

All done. Below is the original G2 thread so make sure to give thanks over there.
