@wanton beis Your device is having eMMC and no nand flash.
If flashing factors Android on the bootloader in the eMMC can only booting eMMC or old bootloaders from the sd-card like Multitool.
If eMMC is empty the SOC is looking for one sc-card for bootloader and if you have written one new arbian image on it it shall finding it and booting OK and also can booting USB-flash from the sd-card (jump starting).
Then writing Android or one old Linux on the eMMC it can only booinng from eMMC system or sd-card all with old system so need updating the bootloadre in the eMMC or erasing the eMMC for  booting newer systems from  the sd-card and gettig jump loading of USB-flash.
