Remove the six 4.0 mm Phillips #00 screws that secure the midframe to the phone.

Ensure you retain all six of the 4.0mm screws! These hold the midframe securely and closely to the motherboard. The three small snaps on the back cover that attach to the midframe ensure the NFC antenna and wireless charging coil connectors contact securely with the motherboard, and work reliably.

To replace the LCD screen and digitizer, remove the additional four 4.0mm daughterboard cover screws with the same screwdriver. You may have to pierce through clear adhesive material to remove them.
