Hi! I also owned a Q96 Mini Plus (https://www.aliexpress.us/item/3256803907514359.html?gatewayAdapt=glo2usa4itemAdapt&_randl_shipto=US). It carries the same brand name with your device but with slightly different chassis. I already tried different device tree blobs (.dtb) with different operating systems. How did you managed to boot the device in Armbian?
