Help reinstalling/flashing original OS on my Ellipsis 8

I have a Verizon Ellipsis 8 that I used specifically for flying my DJI Phantom 3 drone. A couple months ago, the tablet insisted that I upgrade OS. When I did, it deleted my DJI Go app and says its not compatible with DJI Go now. I want to flash it back to the old OS. Im currently sitting on 5.1.1., so Im assuming I need to flash back to 4.4 (KitKat)
Can someone help me with this?
