Touch screen not funtioning

recently, my mx3 touch screen suddenly not functioning. i tried to upgrade, downgrade and upgrade again with clear data to the latest fw 4.xx but still, it did not work. Only power, volume and halo buttons are functioning. Is it hardware problem? what should i do? how do i fix this?

Does the screen work in recovery mode?

It did’nt work. I used the volume button to move up and down and the power button to enter

I think your digitizer needs replacement in that case…

I think so. Thanks for your response…
