You don't need to remove this. if you go to youtube there is a video of a little boy showing how to do this and it is much more helpful. This step is not clear and you can damage the device taking that ribbon off!

can you be more specific about video? I have no idea how to replace the flat cable into the ZIF connector

The ZIF (Zero Insertion Force) connector is a locking connector. You need to lift the dark plastic tab that runs across the connector so that it pivots up on the hinge located near the middle of the connector. This plastic tab is a lock that secures the ribbon cable in place for the screen to work. Once the hinge is lifted, the ribbon cable should be easy to slide out of the connector. To reassemble, you must slide the cable back into the connector as far as possible with the hinge open. Then gently close the hinge until it locks into place and reapply the tape.

In the first photo, the ZIF is shown in the locked position, and in the second photo, you can see the locking tab in the unlocked position. Be careful not to force the tab or you will break it and will have a much more serious problem.
