please try to be a little more specific.
This is to avoid the stupid question like.. "are you sure you have a rockchip rk3228"?!
for example, can you tell me if libreelec starts from the sd card!? and the multitool?! Are you just having problems installing it on internal storage?!
Finally, could you send some photos of the board contained in your box?! MXQ PRO 4K can also contain amlogic or allwinner chips.
