There seems to be an issue with the screen replacement proposed with the guide, they don't match. I ordered the screen replacement (Display assembly LCD) for my Note 2. My phone is a N7100 (international 3G model) and the replacement came labelled for N7105 (4G/LTE model). There is a difference in the clipping path for the antenna cable travelling from botton to top: the path is longer and exits on the external side of the motherboard instead of the internal side.The antenna cable can thus not be plugged back on the N7100 model.
As the LCD assembly pieces labelled with the phone model are "not for sale", you have to match your model with either the one sold by AT&T or the one sold by Verizon. It looks like the AT&T LCD is for the LTE (N7105) devices only....
Thank you for the link to the videos, it helped particularly for the vibrator and power button.
Start with the top clip. You can see it located next to the three battery connectors. Insert the spludge from the side gently to push, the clip should go off.
Once this clip is off, the bottom battery clip can be unclipped simply by gently moving the two pieces apart.
