Three weeks ago, it was in toilet for three hours. Recovered, separated panels, dried, Apple and white screen flashed every two or three seconds. Installed new battery. It came on, worked normally for maybe ten minutes. Charged it. It was at 52% when installed. Charged it to 70 + % . Now it won't come on. When I plug it back in charger white screen flashes every two or three seconds like before. But, it will not boot up and once unplugged from the charger, it will not even flash the white screen with the Apple logo. Any help out there ?
