Rbox has released a pre-rooted version of the 188.8.131.52 software update for the Amazon Fire TV 2. As always, you can download it over on XDA and install it using TWRP. This will allow those of you with rooted Fire TV 2s to update to the brand new user interface that is currently being pushed out by Amazon. If you have the means, be sure to thank rbox for his continued support by donating to him. While most non-rooted Fire TVs are still waiting for this update to arrive, rooted devices get to install it earlier than most thanks to rbox’s quick release.
