How do repair my motherboard?
I dropped my phone in the hot tub. I got a brand new J3 to replace it with but want my videos, pictures, text messages, phone book and whatever else back. I've tried swapping out screens and battery but to no avail. It won't turn on or take a charge. I'm fairly certain the problem lies in the motherboard somewhere, because the new phone won't work using the old screen or the old phone's battery. The phone heats up when I plug it into a wall charger. Using a new and complete motherboard means losing ALL of my data. So can I use my old memory chips (or whatever they are called) on my new motherboard to recover my data? If so, how and what is involved?
