this is how I’ve manage to have LibreElec workign from SDCard
Have Android Vim_Nougat_Root_170421 installed on Khadas Vim eMMC
Write either LibreELEC-S905.aarch64-8.0.2.img, or LibreELEC-S905.arm-8.0-8.0.2b.img from kszaq to the SD Card with win32 disk imager
Delete “dtb.img” from SD Card if exists.
Have the aml_autoscript.zip on the root of the SD Card. Boot from Android, go to settings and find “Update and Backup App”, under the UpdateLocale section. Click Select, select aml_autoscript.zip, click update. Note: Leave “Wipe Data” and “Wipe Media” unchecked/unticked. The Vim will reboot, it will do so a couple of times.
Voilá, LibreElec booting.
but i don’t know where find aml autoscript.
i’m not interest by dualboot.
