I have a kindle oasis (KOA2) with firmware 5.9.2.0.1. According to the first post I have to be at 5.10.3 or later (not too later). I have long had the file on my oasis that prevents updating. How do I update the firmware, while controlling the process so I don’t get 5.12.x (evil) installed? Is there a preferred firmware in my range.
BTW, my wife’s PW3 is 5.9.6.1. That puts her in my situation too.
Thank you.
