MXQ Pro S905 RLT8189FTV Firmware Request

The stock firmware was working fine but was slow, so I thought to update the firmware (should do factory reset), and I tried many different firmwares, and either they don't work (maybe different hardware) or the remote and the wifi is not working, I can live with the remote not working, but I need the wifi, so would somebody recommend a firmware that would work with my box, thanks in advance
