Bought new backplate, now NFC doesn't work

Hey all,

A few months back (I procrastinated finding a solution to this issue), NFC was not working because one of the locking tabs on the backplate had broken off, and the NFC contacts on the backplate and the phone weren't coming into contact (confirmed by pushing real hard in that spot, which allowed NFC to work). I ordered a new backplate, and it fits perfect. However, the NFC still does not work, even though the contacts are clearly making contact. I don't know exactly why it isn't working, hopefully someone here can help. I do have an idea as to why it isn't working, though.

When ordering the backplate, I opted for the International Note II's backplate because I don't particularly like the AT&T logo on the back. Could be that I require different drivers for the new NFC chip?

If anyone could help, I would greatly appreciate it! If I missed any information I'll be glad to provide it.

I bought it from Samsung on Amazon, so yes it's official. I've flashed several ROM's since I got the new back, so that's a no-go. Also, I can put on the old back and push hard on the spot where the contacts are and NFC works. Do you think getting NFC files from an International ROM would work?

Update: decided to do a logcat

That's what I thought, and I've been searching around for the drivers with no luck. Any idea where I could get them?

And thanks for your help!
