This Kodi 17 Krypton fork is intended to be installed on devices with 4.0+ Kitkat operating systems. FTMC may or may not work on 5.0 and above android operating systems.
You no longer need the addon_data.zip to complete installation so please remember to ignore that step.
I highly recommend configuring your advanced settings xml after the installation of my backup files. To learn how to configure your advanced settings click here
