Ok so here's my exact steps - I still think I am missing a step
This is for Balbes150 latest armbian release for the MXQ S805
Write image to SD card using Win32disk
Open SD card and drop DTB file from the DTB folders provided, onto root of SD card, rename dtb files 'meson8b-hd180.dtb' to dtb.img'
Place SD card into MXQ and toothpick to start the initial boot
Nothing happens 'waited 5-10 mins' also tried various other DTB files that are available
Any input would be greatly received
Many thanks for your hard work on this
