TEST CASE:
1. Flash a device with bootstrap or upgrade to latest image
2. Go to system-settings / About / Developer mode
3. Toggle developer mode

ACTUAL RESULT
On a freshly flashed device, toggling dev mode on does nothing
On an upgraded device with dev mode enabled, toggling dev mode off does nothing

WORKAROUND
Flash with --developer-mode

= original description =
Using a krillin on rc-proposed, developer mode does not enable an adb shell:

ubuntu-touch/rc-proposed/bq-aquaris.en #159

$ ubuntu-device-flash touch --bootstrap --channel ubuntu-touch/rc-proposed/bq-aquaris.en --recovery-image recovery-krillin.img

Then boot device to wizard, walk through (I configured wifi, 5555 passcode and have 2 SIMs online in the device). Defaults for location.

Open System settings | about this phone | developer mode

Enable developer mode

On your pc:

$ adb shell
error: device not found

Expected: a phablet shell on the device.

Additionally, if you now reboot, the setting for developer mode is forgotten.

confirmed by om26er on latest arale this morning

[John McAleely (john.mcaleely)]

the buggy behaviour is also present in --bootstrap #158, same channel, same device

[Jean-Baptiste Lallement (jibel)]

A reboot is not necessary, existing and reopening the developer mode page is enough.

system settings logs with the broken toggle.

On an upgraded system with developer mode already enabled it is not possible to disable it.

Seems not to be present on mako:

$ system-image-cli -i
current build number: 272
device name: mako
channel: ubuntu-touch/rc-proposed/ubuntu
last update: 2015-10-26 22:32:25
version version: 272
version ubuntu: 20151026
version device: 20150911
version custom: 20151026

I do get the warnings however, described in #4.

Reverting these imports in /usr/share/ubuntu/settings/system/qml-plugins/about/DevMode.qml to 0.1 fixes the problem:

import Ubuntu.Components 1.3
import Ubuntu.Components.ListItems 1.3 as ListItem

These warnings I assume come to the line [1]. If the property value is false during the Switch.checked property initialization, the actual value will not be updated to the Switch, as the property it is bound to has no notify signal.

Mako is affected, I was running the wrong build. Please ignore comment #5.
