Bug Description

I have an N4 (mako) which, as of the beginning of the month, was able to connect to the cell network with no problems. After a recent update, it seems to no longer be able to see the network.

I'm on the devel channel (not devel-proposed), and currently on build number 119. The problem seemed to begin prior to build 113 - I applied both 113 and 119 yesterday to try to fix the problem. (I don't use the phone very often as a phone, so it's hard to pin down exactly when the problem started; I noticed the problem only because I saw that I had a voicemail, which I was then unable to dial out to retrieve.)

I know there has been some recent work around flight mode on the phone, and some bugs as a result - but I was under the impression that the fixes for this had all landed in the devel channel by now.

I've manually invoked '/usr/share/urfkill/scripts/flight-mode', and that seems to suffice to bring the phone online; but it's not good that the phone was in an inconsistent state and I couldn't figure out how to enable the modem except from the commandline. (Note that the phone wasn't truly in "flight mode" anyway, since it was still connected to wifi.)

Pretty sure you're still hitting bug #1321627... That said, I'll answer a few of your points, and get your opinion on whether we can consider this a DUP.

First, we did land fixes for the above bug last Friday ( 20140711 ) and the resulting urfkill package ( 0.6.0~20140708.110711.a0581f3-0ubuntu2 ) landed in image #u127. Also, it looks like we finally managed to land an image today ( #133 ).

Also re: the flight-mode script. Running it with no args should just output the current state of flight-mode. It can be passed 1 or 0 to enable/disable flight-mode.

Finally, unfortunately fixing this without a full flash might require you to update urfkill. Stop it, clean up the bad state file... and restart urfkill ( or reboot ).
