If your experience goes like mine, once the bottom antennas are free the glass will be ready to lift up.

Lift a little, then tilt it to "open like a book" from right to left. You'll have to release the ZIF lock for the keyboard cable.

Remove the black sticker on top of the lock holding it in place

With a plastic spudger or fingernail, delicately lift the lock tab. It lifts up away from the cable (moving from left to right).

After that, the cable should slide free on its own!

Now, you just have to free the antennas from the glass. I suggest adding lots more heat, now that you can work safely away from the battery.

Set it on top of a hot compress, drip isopropyl alcohol on it, and peel back the adhesive(s)'' slowly and delicately!'

The antenna traces are orange-brown copper printed on the other side of black paper. You can see them, broken, in the 3rd image here. I should try to draw the shape of each antenna here to illustrate what to avoid, but I don't have those pictures yet.
