ADDITION COMMENT:
With respect the 2013 DROID Ultra family of devices... we are running into some "partner support" issues for the Lollipop upgrade. We are actively trying to work through these issue and I will update you guys as soon as I have more information. Sorry about not having clearer direction for you but my hands are a little tied at the moment until we work through the issue with our partner.
