I was able to recover this device with an Android TV 9 firmware from ATV Xperence, now it works well for android and CE 19 Matrix starts me with the dtb tree of the KI PRO, everything works fine but it needs to recognize the satellite tuner by Tvheadend. If I had this from the satellite for CE 19 the device would be a good thing, I know that it is not easy but by trying some variant of the dtb tree nothing is lost. Thanks
