Hello, I have a Samsung Galaxy S5 Neo cell phone. After entering the system with the + voice, home and power buttons I made a wipe data / factory reset then reboot the system now. After running, displaying on the aquamarine background, welcome start> please ask for some google password and still do not understand why the system does not start. I mention that the phone was bought in the store and not from the operator. This is Samsung Galaxy S5 Neo SM-G 903 F.
