Zero2Go Omini uses GPIO-4 to receive shutdown command, if GPIO-4 is also assigned to 1-Wire, Zero2Go’s software will receive shutdown command unexpectedly. If your Raspberry Pi always automatically shutdown itself after installing Zero2Go’s software, that is most probably due to the conflict with 1-Wire interface.\u003c\/p\u003e\n\u003cp\u003eWhen this happens, you most probably can not log in to your Raspberry Pi because it always shuts itself down before you get the chance to log in. To solve this problem, you will need to take out the micro-SD card on your Raspberry Pi and access its file system via a card reader. You need to edit the config.txt file in the “boot” volume to change the GPIO pin used by 1-Wire interface, or you can disable 1-Wire interface if you don’t need it for now. You need to find something like “dtoverlay=w1-gpio” in the file.\u003c\/p\u003e\n\u003cp\u003eIf you want 1-Wire to use GPIO-18, just change “dtoverlay=w1-gpio” to:\u003c\/p\u003e\n\u003cpre\u003edtoverlay=w1-gpio,gpiopin=18\u003c\/pre\u003e\n\u003cp\u003eIf you want to disable 1-Wire interface, just comment it out:\u003c\/p\u003e\n\u003cpre\u003e#dtoverlay=w1-gpio\u003c\/pre\u003e\n\u003cp\u003eSave the file and eject your micro SD card, and put it back to your Raspberry Pi.
