How do I retrieve data from a water damaged phone that won't turn on?

I dropped my blackberry z10 in the bath a few months ago and dryed it straight away, however the other day it turned off and now it will not turn on no matter what I do so... I took it to the shop today and asked if it was repairable but they said no as the water has corroded the copper or something. But I have data on the phone which means a lot to me, e.g- pictures etc.. and I was wondering if I could retrieve them from my phone somehow easily, please help???

Unfortunately no, hope you have back up on your computer

Did you set up any file sync or backup by any chance? Like BlackBerry Link can save all your photos on desktop.

Put the phone inside a airtight box with some rice to get all the humidity out of the phone.
Wait around 24 to 48 hours and try switching the phone on.
It that doesn't work you can open your device following a youtube video buy some scientific alcool (98%) and clean the phone with it.
I did that for a Nokia N8 and the phone is now perfectly working.
Good luck
