There are three different u-boot files located in the /boot directory: u-boot-s905, u-boot-s905x-s912, u-boot-s905x2-s922 This is needed for how these builds boot on amlogic boxes. Next you need to copy the correct uboot for your box. By sea rching the forums you will find information about what dtbs other users have found wo rk best for different boxes.

You will need to restore the original android firmware before attempting the install. Note: If you have previously run other distributions on the box such as coreelec the below installation will not wo rk.
