This is a straight up BS instruction - both of my strips broke IMMEDIATELY. I ended up with a blow dryer, dental floss, credit card and about a half hour of swearing. This step needs to be re-written\improved.
For everybody who thinks they can skip these steps I commend you. No way I would have been able to get my battery out - two broken strips - without removing the screen. Re-inserting these cables was not really difficult - once the first one is back in place the rest follow quickly.
When replacing the battery you should prepare the cable to sit in exactly as you see it in the picture. I had mine all the way back in (with sticky strips) and had to find a way to fit the cable in with the weird way it bends. Dry fit the battery with cable in place - lesson learned.
The new suction cup (plastic handle) is not so suctiony. Prepare for this thing to pop off a couple of times when opening the case.
