The midframe is made of plastic and located above the battery space.

Using the Phillips #00 screwdriver, remove the ten 3 mm screws from the midframe.

ATTENTION - Be aware that the 10th screw is actually underneath the round white sticker marked with the green circle at the bottom left. Do not remove the screw next to it marked with the orange circle or you will damage your midframe board.

Lift the bottom of the mid frame directly up and remove it from the device.
