I can not find ANY repair guides for just repairing the charging port on the Samsung Galaxy S5 Active. I have purchased the Charging Dock Port Flex Cable to replace it, but I have not found ANY instructions or any videos on how to replace it. I was hoping for any help at all!

Follow the guides for the motherboard replacement and then remove the two screws on either side of the home button bar and the single screw on the bottom center of the phone. Now that the two screws have been removed, the outer plastic around the bottom of the device can be peeled away. After that there are two plastic covers over the charge port assembly that can be peeled away. Keep in mind that there is a lot of adhesive on these parts and it will take time and patience to remove them and the device will no longer be water resistant.
I am unsure what stack and back means but the new parts typically come as an entire assembly. With the pads for the buttons to push, the white face, the USB port, antenna connector, and microphone attached.
