Phone randomly shut off. want to retrieve internal memory

Hey everyone, I have a lg g3 that has picures/music on the internal memory. Phone was working 100% fine and randomly had the screen turn blue while watching youtube and it shut down. wont take a charge, wont do anything. pressed power + up, power + down. . plugging into computer. completely dead. Is there any way i can remove the memory from the motherboard and put it on a working lg g3? I have a spare available. i've done some simple soldering on boards ( xbox controllers ) and am willing to try it. any other options?

thx
