Comment 6 for bug 1433442

Could I get you to test silo 029 (https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/landing-029/+packages) and report back if it fixes all the issues you had without you noticing regressions?

Use the citrain tool (you need either the wily version or vivid-overlay version of phablet-tools) like: citrain device-upgrade 29 0000 ubuntu

Double check dpkg -s libqt5quick5 gives you 5.4.1-1ubuntu9 on the device.
