Jan and Jeffrey,

I can´t get it to remain connected for a extended period of time, or enough time to get a log to you. I can see the icon become blue for 5-10 secs and then disappear.

I´ve gone through the motions multiple times.

I can´t seem to replicate what I did 2 hours ago, where it remained connected for at least a good 10 minutes after OTA to week 51.

I figure the worst thing that can happen if I copy the bluetoothd file from usr/sbin, the week 46 version into the week 51 firmware, is that the device will bricked. Maybe that is something to try?
