With my E5, if I well remember:
a) in system setting/devel mode set the pin (4 numbers)
b) I don't remember now if it is also necessary to set devel mode “on“
then in the terminal:
- android-gadget-service enable rndis
- sudo tethering enable (the phone ask the pin...)
of course 'hotspot' and 'mobile radio data' must be set “on“.
At "the end“:
-
sudo... disable
-
android...disable rndis
-
'hotspot' off
-
'wireless network' off (set on by hotspot)
-
'mobile radio data' off
reset also pin (if you want) and devel mode.
