The Odroid XU4 has a hidden boot sector that is only visible on the Odroid itself (can't be written by a card reader). There are a couple possibilities:
1) If the eMMC already had a working image before flashing HassOS:
* It will be booting to uBoot (but no further).
** If you have the serial adapter, you should be able to enter `distro_bootcmd` at the uboot prompt to continue booting.
** If not, flash the HassOS image to an SD card and boot off that temporarily (while the eMMC is also plugged in).
* If you have the serial adapter, you should be able to enter `distro_bootcmd` at the uboot prompt to continue booting.
* If not, flash the HassOS image to an SD card and boot off that temporarily (while the eMMC is also plugged in).
* Once booted, login at the prompts and then enter `dd if=/dev/mmcblk0 of=/dev/mmcblk0boot0 bs=512 skip=63 seek=62 count=1440` at the linux prompt.
* Reboot with eMMC (don't forget to flip the boot switch to eMMC)
2) Clean/wiped/corruped boot sector:
*You'll need to follow [Hardkernel's instructions](https://forum.odroid.com/viewtopic.php?f=53&t=6173) to get a working boot sector. Then flash HassOS and follow instructions above.
*Alternatively, you can try flash HassOS to both an SD and eMMC, then boot off the SD with the eMMC also plugged in, then run `dd if=/dev/mmcblk1 of=/dev/mmcblk0boot0 bs=512 skip=1 seek=0 count=16381` at the Linux prompt. Note that this is untested, but in theory should work..
