Install Kodi to the Fire TV

Note: If your APK file name contains spaces, make sure you put quotes around it in the adb commands. On OS X and Linux, you may need to prepend ./ to the adb commands.

On your host (PC or other Android device), download your desired Kodi APK
Open a Command Prompt (Windows), Terminal (OS X/Linux), or Terminal Emulator app (Android)
Navigate (CD) to the directory with your Kodi APK (In Terminal Emulator on Android you only need to run the adb commands)
Run the following commands

adb kill-server
adb start-server
adb connect <ip-address-of-fire-tv>

ADB is connected when it reports the message “connected to:”
Run one of the following commands
```
adb install <apk-file-name>
```
(or if you are upgrading from a previous Kodi install, use this instead)
```
adb install -r <apk-file-name>
```
Installation is complete when it reports the message “success”

(Note: For Android you need to type in the full path. e.g. >adb install /sdcard/Download/apk-file-name.apk)
