Getting the display ribbon back in place is the most difficult maneuver in the whole fix. I actually broke the black plastic tab in half while trying to close it back down, (be very gentle with it!). Managed to put the broken half back in(tweezers and patience) and get that ribbon in and put it back down. This battery replacement was the most difficult/tedious repair I have ever done. Don't do it unless you are brave and stubborn.
