IPhone 4s water damage question. Retrieving data

Working on a customers iPhone 4s that she dropped in tea. We were able to get the phone hooked up to a new battery and charging port, but it’s not reading it in iTunes or ifunbox

The phone gets read by the computer itself and shows the amount of data used on it, but you open the folder a doesnt show any pictures or videos.

Anyone know of a way to get the data?
