Hi, where download the version firmware 25102016?

just for the record this update that i have im still using and it still works fine for me, ive seen the update available for android 7 but im sticking with what i have because like i said its working just fine, and my phone still works like day 1 and im very satisfied. also in case anyone is wondering im pretty sure you could use this same method detailed above to update your phone to a different rom if thats something you want to do but from what i can tell the android 7 rom still has bugs so im not messing with it, as the saying goes if it aint broke dont fix it.
