This is the trickiest part in this whole guide. Be careful not to damage or tear any cables or wires, or damage any components.

Detach the 2 ZIF connectors in the bottom left and right side of the motherboard. They are wider than others so they're easy to spot.

The connectors have flaps on the sides! I didn't know this at first and was confused why they didn't want to come out easily. You must lift them up and then out to detach them. When putting them back in, make sure the side flaps are securely inside of the connector.
