This tutorial works with all models including the Fire TV Sticks and Fire TV Cube.
You should now have Kodi installed which you can then access several ways. One way is to go to the Apps section on your main menu, and it should appear in Your Apps Library. Another way is to go to Settings, Applications, Manage Installed Applications, and you should see it there.
64-bit vs 32-bit?
Amazon Fire TV 2 – This device supports both 64-bit and 32-bit apps. I have always chosen 64-bit and never had problems. I haven’t noticed any performance boost with either.
All others – Any other devices not listed above will have to go with 32-bit. Although technically the Fire TV 3 dongle and Fire TV Cube may be 64-bit devices, they run a 32-bit Operating System which does not allow the installation of 64-bit apps.
This add-on will eliminate the dreaded “Memory Full, Please Delete Some Apps” message.
