XDJ XZ navigation button problem
I have an xdj xz controller and there was a problem with the navigation button on the controller.
Specifically, if I access a folder on usb flash (or if I use in performance mode with rekordbox) and I want to navigate through the folder, when I rotate the navigation button, the selection of the song jumps randomly from one song to another even if I rotate slowly and steadily. If I rotate in one direction, the song selection jumps back or forward. I would like to do a reset of the controller, a reinstallation or firmware downgrade but I did not find anywhere how to do this.
