My sister in law's Iphone 6s has water damage. She splashed some water on the screen and wasn't aware of it, so was left like that for a few hours and is dead as a dodo. I've been tasked with sorting it out... She had years worth of "precious" photos on there (I'm guessing mostly selfies....) and wasn't logged on to icloud. I tried drying it out in rice, using silica gel and took it to a shop that used a drying machine. Anything else? Can the memory chip be removed and soldered onto another Iphone's logic board?
