Updated to KitKat 4.4.2, today. Faster RAZR M is nice. Jawbone device not pairing is not so nice. My ERA ear piece shows now as "v1.2", and not ERA by Jawbone. Attempting to pair yields a "pairing rejected by v1.2" message. I've rebooted the phone, and updated the ERA to its latest (v1.2). The phone will pair with my HP.
Any ideas appreciated.
