Question about KingSmith WalkingPad S1

I have the Walkingpad S, and it has 2 buttons on the device, M and A as a touch. I managed to hold down the M button on the device and the middle button (Start/Stop) on the remote control at the same time. Then came options, with up, down came speed and there I could unlock the 6. I can't register the apps either, but that's how it works now. Some models have the button on the right side, but that should also work. Good luck and good walk!
