Tools used in this guide
Phillips #00 Screwdriver
Step 1 — Dock Connector
The display assembly is still connected to the iPhone by several cables, so don't try to remove it entirely just yet.
Rotate the display assembly up until it is at an angle of approximately 45 degrees.
Continue to hold the display assembly with one hand, and use your other hand and a spudger to disconnect the black ribbon cable labeled "1."
Rotate the display assembly up until it is roughly vertical. This will allow easier access for disconnecting the remaining cables.
Use a spudger to disconnect the black ribbon cable labeled "2."
Use a spudger to flip up the black plastic tab holding the remaining ribbon cable in place. The black will rotate up 90 degrees, releasing the ribbon cable.
Slide the ribbon cable out of its connector, and remove the display assembly from the iPhone.
Insert your SIM eject tool or a paper clip into the hole next to the headphone jack.
Press down on the tool until the SIM card tray pops out.
Grasp the SIM card tray and slide it out of the iPhone.
Use a spudger to disconnect the ribbon cable labeled "4."
Use a spudger to disconnect the ribbon cable labeled "5."
Use a spudger to disconnect the ribbon cable labeled "6."
Carefully peel up the small sticker labeled "Do not remove."
Remove the following 8 screws:
Five 2.3 mm Phillips #00 screws with partial threads securing the logic board to the rear panel.
Two 2.3 mm Phillips #00 screws with full threads securing the logic board and camera.
One 2.9 mm Phillips #00 screw from beneath the "Do not remove" sticker.
Use a spudger to gently pry the camera up and out of its housing in the rear panel. The camera cannot be removed entirely yet because it's connected to the bottom of the logic board.
Use a spudger to gently pry up the end of the logic board closest to the dock connector.
If the board won't lift up, double check to make sure all the screws securing the logic board have been removed.
Slide the logic board towards the dock connector and out of the iPhone.
Remove the following 3 screws:
Two 1.5 mm Phillips #00 screws, one on either side of the dock connector.
One 2.4 mm Phillips #00 screw near the ribbon cable labeled "4."
Lift the dock connector assembly up and out of the iPhone.
