HI @isorrentino! Me and @fbiggi replaced the broken tendon with a new one and tested the robot. Now it works properly!

[!Warning] Just one important suggestion. If the neck tendon is broken, the pitch and roll joints (0 and 1) have to be disabled from the configuration files, because otherwise the motor keeps running and the tendon rolls around the gearbox.

In fact, because of this we had to remove the head from the robot and disassemble the joint in order to remove the broken tendon.

Closing! ✅
