I have some dvb-t2 android box, see post (unknown s905d dvb-t box), and tried your ROM, but did not work. It wrote DDR init failed...
Any kind of ROMs should not be installed on a box that is not properly identified. Moreover, this is particularly true for boxes with tuners. If you have several pieces of this box, it would be best to make a flashdump from one of the working pieces.
