There is a bug when modding some S905X img firmware. When you make a modification and you repack it will never boot and goes to recovery. To fix unpack and replace aml_sdc_burn.UBOOT and UBOOT.USB with the ones in the attachment.
I would imagine when they update the customization tool this will become moot.
To Root
A service must be started in init.amlogic.board.rc
service sudaemon /system/xbin/sudaemon --daemon
user root
group root
disabled
oneshot
Start the root service between "on boot" and "on fs"
"start sudaemon"
Place SuperSU in /system/app
and place su and sudaemon in /system/xbin
Some firmware already has the service and just needs SuperSU placed. There will be some trial and error.
