The Parameter 4 knob on my new Zoom G7 does not work. I adjusted it once and now it does nothing. I hope nothing is physically broken

I have tried restarting it. I cannot update the firmware because I don't have MIDI cables. Also, it says that it has v1.06, but the latest on the zoom site is v1.05.

Is there any way I can fix it? Its a pretty important knob.
