Step 4
• Remove the following screws securing the battery connector to the logic board:
• One 1.7 mm Phillips screw
• One 1.5 mm Phillips screw.
• Use a plastic opening tool to gently detach the battery connector from the socket on the device. Start lifting off the connector from the bottom side, by placing the tip of the tool between the loudspeaker enclosure and the metal cover of the connector.
• The battery connector comes off vertically from the logic board. Do not apply force sideways.
• Pay attention to the pressure contact underneath the top screw of the battery connector. This may come loose while prying the battery connector from its socket.

Step 5
• Use a plastic opening tool to pull the pressure contact from underneath the battery connector.
• When reinstalling the pressure contact, be sure to clean it with a degreaser such as windex or isopropyl alcohol. The oils on your fingers have the potential to create wireless interference.
• Take notice of the position of the small black ground clip on the upper screw of the battery connector. This clip is attached only by the upper screw. When reinstalling, it must be aligned so the gold contact point will press against the back cover.
• Be careful not to rip off the battery connector socket soldered on the logic board. There are 4 very small soldering points awaiting this mistake!

• If present, peel the piece of black tape covering the hidden screw near the power button.
• Remove the 2.6 mm Phillips screw securing the logic board near the power button.
• (Use caution when removing this screw and removing the power contact held by it; the contact tab will come loose with the screw)
• Notice the small rubber bumper under the screen & digitizer cables (which are detached at top above the Q-code). This bumper can fall off of the logic board when removed or get stuck to the cables and fall off later.

Step 24
• Carefully lift the logic board from the end closest to the speaker enclosure and slide it away from the top edge of the iPhone.
• Remove the logic board.
• Before reassembly, be sure to clean all metal-to-metal contact points on the logic board (not the mating halves of connectors) with a de-greaser such as windex or isopropyl alcohol. The oils on your fingers have the potential to cause grounding issues.
• There is a small rubber bumper that sits on the top edge of the logic board where the digitizer and screen cables come through the case. It protects the cables as they bend over the top of the logic board. This can either get stuck to the cables or fall off the logic board when it comes out. Look back over step 22 for more details.
