Ok i have fixed it finally... Things i did to fix it:

- Upgrade Windows 10 to Anniversary Update edition or later.
- Reinstall/pair the gamepad.
- Calibrate in windows and in-game.
- Enjoy.

PS. The gamepad still needs to upgrade the firmware with an Xbox One console, not only with the Windows 10 Xbox Accessories App.

EDIT: Today i bought the X1 kit play-n-charge and when i connect the gamepad with usb cablem the accessories app recognize the gamepad and let me update the firmware... Only with usb cable.... And the unresponsive issues (1 - 3 seconds the gamepad stuck) gone too
