Replacing the screen requires following the steps in reverse. Mating the flex cable from the new screen into the zif connector takes a bit of precise tweezer work.

The black tab that holds down the flex cable has lifted up from when the old flex cable was removed. Make sure the black swinging latch is still up! Now slide the new flex cable into the zif connector. Make sure it is lined up properly and lays flat up under the black latch. Then, using the tweezers push the black tab down onto the flex cable.

The black tab should now be flush against the flex cable to hold the flex cable in place and give proper contact for your screen to function properly!

Cover the hole with tape or the black tab that was originally there in order to keep dust out
