Do not be concerned with the difference between I747 and I747U they are the same where you should be concerned is with the difference between I747/U Vs. I747M
Flashing the wrong bootloader will eternally brick your phone until it gets jtag'ed.
so be careful and ask questions when you aren't sure.

I need to bring this phone back to life when it returns and I will need more help then.
I Used auto root some time ago to get something to work that never did. I totally forgot about it then took an OTA update Last Saturday to what I thinks was 4.3 that ended up in hangs and continuous reboots. Not sure why this failed because I have taken one other OTA that was successful. I was dumb enough to call AT&T who in turn called Samsung Support. They asked me to take it to Best Buy for reflashing. That was a waste of 2 hours of my life and a massive fail. Called AT&T Back who again called Samsung. Samsung asked me to send the Phone to them for re-flashing and they knew it was out of warranty. Dummy me thought well if it is out of warranty I don't need to worry about if it is rooted or not. Besides who should know better how to and have the resources to re-flash it back to stock than Samsung. So I sent it to them. We all know the rest of the story. They found it was rooted and wouldn't touch it. So now you know why it is not in my possession till Monday.
