Saving a possibly water-damaged phone?

My phone got soaked at the beach. I took it apart immediately and dried it with a towel. As I was on holiday, I did not do the rice trick but I made no attempt to turn the phone on or charge it. I left it for a few days once I was pretty sure it was dry. I checked the white water-damage indicator which has not turned pink. But when I tried charging, I had no response. When I plug it into the PC using a USB, the red LED light flashes on but then fades in and out. I am fairly sure this phone has completely fried but I was wondering if there was any chance of repairing it enough to let me transfer pictures and documents from the phone to my computer?
