I did the same thing, and it works! Thanks very much for that! Below is the diff in my config. One thing I notice is the different KnownSims. I switched from one Chinese SIM card to a different Chinese SIM card and also moved to Hong Kong (i.e. roamed) at the same time. So I guess that's a fairly obscure scenario.

Currently between "Bluetooth" and "Sound" I have a gear icon and the caption "indicator-network". When I select it, the rest of the screen is blank. There are no settings available and no way to connect to a wifi network. On the System Settings app, if I tap on the "Wi-Fi" icon, I can see "Previous networks". But below that the page is just white, there is no way to select a wifi network. Rebooting the phone doesn't seem to fix the problem. Given that this is an MX4 and therefore the USB port doesn't work, and there's no SD card slot, there's vanishingly few ways to get data in and out of this phone now. If there's a solution to the problem, it's going to have to involve something other than updating system software. Current system software is Ubuntu 15.05 (OTA-12).
