Rbox has released a pre-rooted version of the 220.127.116.11 software update for the Fire TV 2. You can download it over on XDA and install it using TWRP as always. This allows Fire TV 2 owners with rooted devices to update to the latest software version without losing root. Those of you with the first generation Fire TV, a pre-rooted version of 18.104.22.168 was released last week. If you have the means, be sure to thank rbox for his continued effort by donating to him.
