Is there a software upgrade to lollipop 5.1 for the Alcatel OneTouch Pop Astro model 5042T

[AC Question]

Is there a Software upgrade to lollipop 5.1 for the Alcatel OneTouch Pop Astro model 5042T? KitKat 4.4.4 is installed on this phone. When I check for updates, it states that there are no updates and that I have the latest update. My phone is rooted so would be able to install a custom build of Lollipop 5.0 for this phone if one is available or if one can be created.
