Software updates 220.127.116.11 for the Fire TV and 18.104.22.168 for the Fire TV Stick appear to consist of only bug fixes and no new features. These updates have patched the last remaining Stagefright vulnerable library. If you still have your hopes set on a new rooting method using the Stagefright vulnerability, you’ll want to avoid this update. Additionally, it appears these updates have also fixed the HDCP blank screen issue that some people have been experiencing. It does not appear as though Amazon has removed the newly added “always on” HDCP encryption, however several readers have told me, with this new update, they are no longer seeing blank screens when waking their Fire TVs and Fire TV Sticks from sleep mode.
The Amazon Appstore app, which controls the “Apps” and “Games” sections on the Fire TV, seems to have received a lot of attention with this update. Unfortunately, I could not find any indication with this update that Amazon is adding Amazon Underground to the Fire TV. This doesn’t mean the Fire TV will never have access to Amazon Underground apps. It just means that it’s unlikely to be part of this update. The Amazon Music app, which controls the “Music” section on Fire TV devices, has also received some care with this update. But again, no new features were found.
