ps4 controller won't connect on initial startup [duplicate]

My PS4 is on the initial startup screen (when you first buy the system) and the controller doesn't connect to the system. I've tried resetting the controller and using different wires, but still nothing. The controller only connects to the system on safe mode (with any wire), but after I choose an option, it goes back to the initial startup screen and the controller doesn't work anymore. Does anyone know how to fix this?

Solution 1:

What works for me (every time so far) is to turn off the PS4 (by holding down the power button) then wait a few seconds (about 10) seconds to make sure it's turned off completely, then unplug the power cable and wait another few seconds (waiting 10 seconds works fine for me). Then replug the power cable and press the PS4 button on the controller and it SHOULD start on its own. Every now and again it will turn on (and give the blue light on the controller) and at the start-up screen act like it doesn't recognize the controller again. If it does that, press the PS4 button again and let it flash white until it reconnects again. Sometimes I have to press the button 2-3 times before the console FINALLY contects, but this method was worked for me every time so far.
