I had to burn the sd-card with balenaEtcher software, don't uncompress the image
images are listed here: https://wiki.odroid.com/odroid-xu4/odroid-xu4 I used this one https://sourceforge.net/projects/openmediavault/files/OMV%204.x%20for%20Single%20Board%20Computers/
after you clone the sd-card you might want to repartition to use the whole space I used this guide for that: https://geraldonit.com/2019/10/19/how-to-resize-a-btrfs-root-partition-on-oracle-linux/
