Are all variants of the note 4 the same? An att mobo could go into a vzw/sprint body or vice versa?

I would also really like an answer to this question

No. Even Samsung wouldn't accept even a paid repair because parts between models are incompatible.

I've tried to have an SM-910G here and if you are to replace it with an SM-910C, you'll also need to replace the front and back cameras.

I have done a few Note 4 motherboard replacements...about 10 or so. I have not been able to simply "To reassemble your device, follow these instructions in reverse order." I always have to separate the screen from the mid frame in order to plug the 2 top ribbon cables back to the motherboard. I can't figure out a way to get the ribbon cables plugged back in without doing so. This screen separation process is very tedious, long, and stressful as it could crack the AMOLED screen if you're not careful. If someone can show me exactly how to simply, "To reassemble your device, follow these instructions in reverse order" it'll make it a lot easier for me. Thanks.

Agreed. That screen was by far the most difficult screen ive ever removed from a phone. It would be SOOO much easier if it were broken and you didn't care.
