Armbian + KODI (Ubuntu\Debian) for SD & USB & eMMC

I attempted to test some images from: https://disk.yandex.com/d/pHxaRAs-tZiei/5.77/S912
I could NOT get
Armbian_5.77_Aml-s912_Debian_stretch_default_5.0.2_desktop_20190401.img.xz
or
Armbian_5.77_Aml-s912_Debian_stretch_next_5.1.0-rc3-next-20190402-g05d08e299-dirty_desktop.img.xz
from https://disk.yandex.com/d/pHxaRAs-tZiei/5.77/S912/NEXT
to boot at all; first, when I tried to use Etcher to burn the images to SD Card, they were ignored and I was instead booted into the EMMC (Where I have Khadas’s Official Ubuntu Installed), then when I used HDD-Raw-Copy-Tool from http://hddguru.com/software/HDD-Raw-Copy-Tool/ , they wouldn’t boot anything at all, just stayed on a black screen, this was the same method I used to burn and boot
Armbian_5.77_Aml-s912_Debian_stretch_default_5.0.2_desktop_20190318.img.xz
(No Longer Found) which worked and booted up fine.
Why are the other two images not working and giving me problems? Can someone please help me fix this? I tried burning the images 4 different times, on two different OSs, one in Linux Mint, and the other in Windows 10; none of the attempts worked, Only the 20190318 image. Please let me know how I can boot the other images. @balbes150 it’s my understanding you built these images? Why do they not work and why was 20190318 removed?
NOTE: this is all for a Khadas VIM2 Max (First Edition)
