This Kodi 17 Krypton fork is intended to be installed on devices with 4.0 - 4.4.4 Kitkat operating systems. This media center may or may not work properly on 5.0 and above android operating systems.
You no longer need the addon_data.zip to complete installation so please 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 xml click here
