So I used this snipit:
up.analogHeadsetOption
0, 1, 2, 3
The headset mode for the phone’s analog headset jack. 0 - no EHS-compatible headset is attached. 1 - a Jabra EHS-compatible headset is attached. 2 - a Plantronics EHS-compatible headset is attached. 3 - a Sennheiser EHS-compatible headset is attached.
And put this into the provisioner: For Jabra EHS.
up.analogHeadsetOption="1"
So, now it sticks, but for some reason it does not work.
I tried the"select setting and reboot with no network" and that does work.
What am I missing?
