IPhone 3g fell in toilet now it wont restore?

My iPhone 3g fell in the toilet so i took it out and put it in rice for about a day and then the apple would appear. I googled many ways to fix it and they said put it in DFU mode so I did and the connect to iTunes popped up. I connected it to itunes and it said restore so I pushed it. The apple with the loading bar came up on the phone for about 10 seconds and then the phone will just go blank and the error message 9 will pop up. Does anyone know how I can fix this? Well atleast get my iPhone to actually restore.
