Virtual device is stuck on "booting" status

This usually happens when another ADB tool from a third party Android SDK is running and conflicts with Genymotion Desktop built-in ADB.

To solve this:

1. Make sure that no adb server is running. To kill any running adb servers, you can use the command

   adb kill-server

   Or kill any running ADB processes.
2. Set Genymotion Desktop to use your third party Android SDK. Please refer to Configuring ADB for details.
3. If it still does not work, try to reboot the host machine.

If it doesn't help, you may need to revert to Genymotion built-in ADB and make sure that no other ADB services are running before using Genymotion (step 1 from above).
However, you will not be able to use Genymotion and your third party ADB tool at the same time in this case.
