Identify ribbon connector at the top right of the phone.

Pry the black locking bar up gently with a plastic opening tool.

Remove the ribbon wires by pulling them out of the connector with a tweezer.

The locking bar is the small black bar located on the digitizer’s ZIF connector.

Be sure to push the locking bar back down using a spudger after you put the ribbon wire back in since the lock does not lock automatically.
