How to remove motherboard Anfang fix battery connector

I had the same problem as many others with the flickering, rebooting, not charging of the galaxy note pro 12.2 wifi. So I opened the back cover of the tablet and found the battery connector sitting in place but loose. When I touched it a bit too hard it moved and when I tried to push it back it fell apart. Now I have to replace it completely but can find No information on removing the motherboard. I did find a really good video on your website for the 10.1 I believe but my motherboard has a couple of more cable ribbons attached and I am not sure how to remove them.
