This is to fix your issues with Android update.zip, not installing LE to NAND. To make installtointernal work, you may need to delete dtb.img from SD card before booting into LE - and you have to have Android on internal at the same time!
BTW, here's a next build to test for S905X owners: LibreELEC-S905.aarch64-7.0-devel-20160912122244-r23334-g1790972.img.gz
ok, so i have copied the recovery.img and dtb.img from the update.zip to the SDcard, booting to the recovery, all good.
But when i try to install the update.zip, i get a Dtb chack failed, error in update.zip (status 7).
And as far as i know, this is because the box says it is an nexbox_s905 or something, and not P212, so it wont install the update.zip
EDIT:
using a twrp version for s905x boxes i get this error:
This package is for "p212" devices. This is a "nexbox_a95x"
Update process ended with ERROR 7.
