Ah that button is usually greyed out, it's meant for if you follow amazon's instruction on their site and put their update file on your sdcard, if you do that then it would let you hit it. That method should still work I believe if you want to update it. Keep in mind that would unroot it and possibly get rid of custom recovery, but it's been a while so I don't remember if it gets rid of custom recovery, then again I just woke up and I haven't used amazon os for the better part of a year now.
