[Q] Replaced motherboard, now it's not charging!

Hey everybody! As the title says, I replaced the motherboard on my SM-G920V with one from my wife's old S6 (also 920v). She thought it'd be fun to throw it at me when she was angry, and shattered both front and back glass. BUT ANYWAY... After I finished installing everything how it's supposed to be, I started it up and was so happy to have my S6 back to OE2! My only issue now is that it won't charge, yet will recognize a charger. I haven't been able to connect it to a computer, because mine was blessed with a lovely RootKit/netbot that took over every aspect of my machine. So if any of my hardware people could help me out, that'd be great! What could I have done wrong?!
