If you’re a developer, or are just dying to sideload those shiny new Android TV apps that your Shield TV friends have been flaunting in your face, then here’s how to install the Fire OS 5 Developer Preview on a Fire TV or Fire TV Stick. Be aware that Amazon does not recommend that the general public install this preview. According to Amazon, it does not contain any new features and is meant to be used by developers to test their apps.
- Register for an Amazon Developer account, if you haven’t done so yet.
- Select the Fire TV(s) or Fire TV Stick(s) you would like to install Fire OS 5 on from this page.
- Be sure your Fire TV or Fire TV Stick is running the latest software versions, which is currently 126.96.36.199 for the Fire TV and 188.8.131.52 for the Fire TV Stick. You can check your software versions from the Settings > System > About menu.
- Now wait patiently. Your Fire TV or Fire TV Stick will receive an over-the-air software update, just like all other normal software updates, that will install Fire OS 5. Amazon says it should arrive in 24 to 48 hours from when you complete step 2.
