Any firmware available for Bush BHA01UR?

any firmware available for Bush BHA01UR ?
I have a set top box from Bush model is Bha01Ur , but it can not play video.
I red specs on other models. it said you need to instal firmware update, after you can play video on the USB, is there a firmware update for this one ?

what would happen if I install a firmware for a different model of Bush set top box ?
