Amazon FireOS System Updates from 5.1.4 to 5.3.1.0 released.

Came out on July 14, 2016 10:30 PM. There is no bin file at this time.

Note: Don't try to downgrade from this. Might brick your FireOS. Need a report on it actually works or not first.

Cannot be rooted. Tested with NewKingrootV4.95_C149_B285_en_release_2016_07_15_1 05203.apk
