Can't invert logic of bltouch

Hi, I'm new writting in this forum but I've been reading it for a long time. I got a geeetech i3 proB, with GT2560 A+ electronics and mk8 extruder. I'm trying to set up autolevel sensor and I'm having some problems. I used Zmax for end-stop and the extra connector of A+ for the servo. Here is how it works right now, I deploy it, stow, test and finally level bed, all from LCD:

I think that the logic of Bltouch is inverted so I use M119 to check end-stop states. When I deploy, M119 shows it TRIGGERED and the red light of the sensor switches off. When I stow, M119 answers as OPEN and the light switches on.

So I tried to modify Marlin 1.1.9 and invert this end-stop but it doesn't mind if its true or false, nothing changes. I tried to change logic of X's endstop and Y's endstop and they both change from open to triggered when I change from false to true.

#define Z_MIN_PROBE_ENDSTOP_INVERTING true

I attach my Config.h so you can see it. It's default from Marlin/examples/geeetech/proB/bltouch/. I has bltouch enabled on pin32 and bilinear probe.


I tried setting up as servo, setting up delay and angles. I tried following manual from antclabs, and I don't know what else can I try. I'll be gratefull of reading any idea and sorry if my english isn't perfect(. I'll keep learning from you))
