After my switch spoil I will do this.
Shortcircuit the RED and WHITE wires of the switch, and let the Black wire of the switch free (that means you just cut the Black wire and do NOT connect the black wire with anything. )
In such a way you can use the ESC but you cannot set the programmable items any more.
If you need to recab the esc again just touch the 3 wires again for 1sec for each throttle range.
Hope this helps
