Data Retreaval after Water Damage?

Hey everyone,

I'm trying to help my sister out with her busted phone. She dropped it in ocean water and picked it up right away. It was left to dry in rice but it will not turn on or charge. The battery seems to be totally dead at this point, too. It also does not do anything when connecting it to a computer. I did some cleaning to the inside to get rid of residue and yet it has not improved any.

All my sister wants is to get the photos saved on the phone off and onto a computer. Is there any way that this can still be done?

Thanks for your time and effort!
