s6 edge motherboard is dead - can I get the data?

Hey all

Please help me. My phone was charging (switched off) and I took it off charge on 46%. I tried to put it back on and it wouldnt turn back on at all. The phone is completely dead and I tried to reboot. I have gone to a phone shop and they have told me the motherboard is dead

I really want to access the internal storage for pictures - is this possible? Can i take off the internal storage chip and put it on another motherboard??

Are there any services in the UK???
