STR 1. Plug a Flame 2. Select nightly 3. Flash Result On the UI, the flash operation still ongoing. Nonetheless, WebConsole stopped logging on a failure. I think there is something wrong with my setup. The first time I flashed an eng build with the addon, everything went fine. Then it failed twice, then it passed again. It seems like some files are missing. It doesn't appear I ran out of disk space or memory. I didn't flash anything else in the middle of my 4 tries. See attachments for details. Repro rate: 2/4 times.

After some more investigation and Alexandre's guess, it turns out ADB gets disconnected and reconnected even after the lockscreen is displayed. This is why it fails at adb-related steps. Then, we need to improve the error message, when this kind of events occur.

If we detect a device running B2G (which is what this is about) we should probably adb shell stop b2g. That will not work, however, on "user" builds.

I suggest we: - if we have root access, we adb shell stop b2g - if we don't have root access, we show a dialog to ask the user to disable lockscreen

This way it will avoid running |adb shell stop b2g| on device which just got plugged in and not really requested to flash.
