Depending on your make and model, your CP Plus camera might not have a reset button. Mine did not have one, so this guide will help you figure out what to do
If your disassembled camera looks something like this, use a pair of tweezers or some wire to jump the two holes. Hold it for 15s. The camera will not beep to signal the reset so you will need to have the live video open as it gets finnickey at times
