- Before pressing the ribbon cables into place, carefully verify that their connectors match the motherboard sockets precisely; magnification with a magnifying glass or jeweler's loupe may be necessary for accurate alignment.
Step 12 | Remove the logic board screws
- Detach the component by disengaging eight fasteners.
- The logic board is attached to the rear case using five screws; each is 2.3 mm in length, features a Phillips #00 head, and has partial threads.
- The logic board and camera are fastened together using two screws; each is a full-thread Phillips #00 screw, measuring 2.3 mm in diameter.
- Locate the "Do not remove" sticker and, underneath it, you'll find a 2.9 mm Phillips #00 screw.
During reassembly, ensure all components are properly aligned and secured according to the original configuration, maintaining specified tolerances and using the appropriate tools to avoid damage.
The camera is secured by a metal strip affixed with the orange-highlighted screw located on the bottom right side.
Before securing the camera with the fully threaded Phillips #00 screw, measuring 2.3 mm, ensure the strip is correctly positioned.
Step 13 | Loosen the camera
- Carefully leverage the camera module from its rear case housing using a spudger, ensuring no forceful movements are applied.
Due to its connection to the logic board's base, complete camera removal is currently not possible.
Step 14 | Remove the logic board
- Carefully lift the logic board's edge, near the dock connector, using a spudger to avoid damage.
Due to its proximity to the 'do not remove' label, the logic board's small, gold-colored grounding tab is fragile and susceptible to damage. Exercise extreme caution to prevent this tab from catching on the device casing during logic board removal; breakage occurs readily. Post-removal signal issues may indicate a damaged ground tab, requiring inspection.
Carefully verify that each screw holding the logic board in place has been completely unscrewed if you encounter resistance when attempting to separate it.
Step 15
- Carefully advance the logic board in the direction of the dock connector to disengage it from the iPhone's internal housing.
Before securing the logic board within the device enclosure following battery installation, establish the camera connection to the board. Prior to fully seating the logic board, carefully position the upper portion, specifically the area housing the SIM tray, ensuring proper alignment. Failure to do so may result in SIM tray misalignment. With the upper section correctly situated, the remaining portion of the logic board can then be positioned. Correct installation is confirmed when the SIM tray aligns with its corresponding aperture in the iPhone case and the camera module is fully and flushly seated.
Step 16 | Loosen the battery
Carefully align the 4mm hex key to the setscrew on the motor shaft, ensuring it is fully seated, and then tighten the setscrew to a torque of 1.5 Nm using the torque wrench.
- Carefully lift the battery from the rear case using a spudger, as it is secured by an adhesive strip that runs along its edges.
- Employing solely the plastic pull tab to detach the battery risks causing damage due to excessive force; therefore, avoid this practice.
- Disconnecting the battery isn't required when replacing the GPS antenna; however, doing so provides additional clearance for headphone assembly removal, though complete removal of the headphone assembly isn't essential for the antenna replacement procedure.
- The iPhone battery is secured to the rear enclosure using a low-strength adhesive, which typically remains adhered to the battery during removal. If your new battery has pre-applied adhesive, no further action is needed; otherwise, carefully move the adhesive from the original battery to the replacement.
- To release a battery that is stuck to the back cover, carefully introduce a small amount of isopropyl alcohol with a concentration exceeding 90% between the battery's edge and the case. Let the alcohol sit for approximately one minute to dissolve the adhesive. Then, use the spudger’s flat end to carefully pry the battery loose. Ensure the alcohol completely evaporates before the new battery is placed.
- To prevent damage, avoid using excessive force when removing the battery. If the adhesive is still holding, add a small amount of additional alcohol to help dissolve it. Ensure the pry tool does not bend, break, or penetrate the battery casing during the separation process.
- Applying gentle heat to the case's rear surface with a hair dryer or heat gun, set to its minimum temperature, will soften the adhesive securing the battery, making it easier to detach the battery from the case back with a spudger.
- To prevent battery ignition, avoid exposing the iPhone to excessive heat.
Step 17 | Headphone Jack
Carefully align the 4mm hex key to the setscrew located on the motor shaft, ensuring it is fully seated, then apply a torque of 1.2 Nm using the torque wrench to secure the fan blade.
- Using a Phillips #00 screwdriver, detach the on/off switch from the front bezel by unscrewing the two screws that hold it in place.
- Verify the switch's extension during replacement; a thin plastic spacer is affixed inside the button and can detach during cleaning. Absence of this spacer may result in insufficient button projection for proper operation, so if lost, substitute with a piece of rigid plastic material approximately the same thickness, such as a section cut from a shirt box lid.
Step 18
Carefully align the 4mm diameter dowel pins with their corresponding holes in both the upper and lower chassis halves, then gently press the halves together until fully seated, ensuring no gaps are visible.
Gently lift the orange ribbon cable away from the back cover, exercising caution.

- Use a Phillips #00 screwdriver to remove the three 1.8 mm screws that fasten the headphone jack and GPS antenna assembly to the rear case; be sure to remember the sequence, because the screw on the left side is distinguished by its slightly larger head.
- A plastic loop positioned close to the headphone jack secures a 3.8 mm Phillips #00 screw.
Step 20
Carefully secure the 1/4-inch diameter hose clamp using pliers, ensuring it is positioned precisely at the 3-inch mark from the pump housing's edge, and observe the warning regarding potential pinch points during tightening.
Using a Phillips #00 screwdriver, detach the four screws that hold the volume and mute switch in place.
The mute switch assembly is located directly beneath the volume switch assembly; during disassembly, carefully retain the small, flexible cushioning pad affixed to the mute switch, as its absence will result in a loose fit upon reassembly.
Ensure the mute switch is set to "off" while tightening its screws. Verify the switch's extension when activated; insufficient projection indicates improper assembly alignment. Examine the space between the switch frame and bezel—specifically, the white gap visible between the two screws located near the 6 o'clock position—to confirm correct positioning. Note that one screw is longer than the remaining three and account for this during reassembly.
