[Bug 1539158] Re: Unable to pair with in-car hands-free system after OTA-9 update


@Stunts: Do the following on your HOST system:

$ sudo add-apt-repository ppa:phablet-team/ubuntu/tools
$ sudo apt-get install phablet-tools-citrain

Now connect the phone over adb (make sure developer mode is enabled):

Still from the HOST system:

$ citrain device-upgrade <silo number> <your device PIN>

PLEASE KEEP IN MIND: This will change the content of the device rootfs
system. If you don't want to reflash via ubuntu-device-flash or don't
know how to do that it might be better to wait until this fix lands with
the next OTA.

Bug description:
  After OTA-9 I started having trouble with my bluetooth connection to the car hands-free system (no sound, and incoming calls no longer displayed the number), so I have reset both the car and the phone connections (eg. forgot the devices).
  Now I can't even pair the phone with the car's system. 
  The car finds the phone, and then asks me to enter the code "0000" to pair the device, but after a few moments, it just says the connection failed and asks me to try again. Which fails again.

  It was working fine just before the update.

  Any logs I should post to help debug?

  PS - The car is a 2015 Honda Civic Tourer, if that matters.
