Introdução

This guide is for replacing the power button cover, not the electronic power switch itself.

  1. If your display glass is cracked, keep further breakage contained and prevent bodily harm during your repair by taping the glass. Lay overlapping strips of clear packing tape over the iPhone's display until the whole face is covered. This will keep glass shards contained and provide structural integrity when prying and lifting the display.

  3. Remove the metal handle from the suction cup. It's easier and safer to grip the suction cup's base instead of the metal handle.

    • Remove the metal handle from the suction cup. It's easier and safer to grip the suction cup's base instead of the metal handle.

    • Be very careful when opening the iPhone so that the cables under the display are not severed.

    • There is a rubber gasket between the silver front bezel and black display assembly. A bit of force is required in this step to separate the iPhone's display assembly. It may help to rock the suction cup back and forth to remove the display assembly.

    • Use a small suction cup near the Home button to gently pull up the bottom portion of the iPhone's display assembly.

    • If the display assembly is too damaged to allow the suction cup to adhere, tape with a strong adhesive such as duct tape or packing tape may be used.

  4. The display assembly is still connected to the iPhone by several cables, so don't try to remove it entirely just yet.

    • 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.

  5. 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". (Cable 1 is for the display)

    • 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". (Cable 1 is for the display)

    • Be careful to insert the spudger from the left, as shown in the picture (UNDER THE RIBBON). If you try to pry up the ribbon from the right, you could damage the ribbon connector and need to replace the display!

    • All connectors except the ribbon connector "3" mentioned in step 7 release upwards.

  6. Rotate the display assembly up until it is roughly vertical. This will allow easier access for disconnecting the remaining cables.

    • 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". (Cable 2 is for the capacitative touch panel)

  8. Please note: You may find on some non-American (Chinese, European) versions of the 3G that the flip up plastic tab does not exist. In this case you would slide the ribbon cable towards the screen until it is removed. When you assemble it, you would apply pressure to the ribbon to insert it back into the ribbon "socket."

    • Some iPhones may have the connector colors reversed (black plastic tab, white connector) for connector "3". Make sure you're flipping up the tab properly, otherwise you may damage the connector.

    • Use a spudger to flip up the white plastic tab holding the ribbon cable "3" in place. The white tab will rotate up 90 degrees, releasing the ribbon cable.

    • Slide the black ribbon cable out of its connector, and remove the display assembly from the iPhone.

  9. Insert your SIM eject tool or a paper clip into the hole next to the headphone jack.

    • 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.

    • If you have an iPhone 3GS, refer to the second picture and use a spudger to disconnect the ribbon cable labeled "7."

    • Be certain that the connectors on the ribbon cables are perfectly aligned with the sockets on the mother board before applying pressure. This may require a magnifying glass or jewelers' loupe.

  13. Remove the following 8 screws:

    • Remove the following 8 screws:

    • Five 2.3 mm Phillips #00 screws with partial threads securing the logic board to the rear case.

    • 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.

    • Note for re-assembly:

    • The screw that goes next to the camera (bottom right orange highlighted screw) also has a metal strip that holds the camera in place.

    • Remember to put this strip back in place before you insert the 2.3 mm Phillips #00 screw with full thread next to the camera

  14. Use a spudger to gently pry the camera up and out of its housing in the rear case.

    • Use a spudger to gently pry the camera up and out of its housing in the rear case.

    • The camera cannot be removed entirely yet because it's connected to the bottom of the logic board.

  15. Use a spudger to gently pry up the end of the logic board closest to the dock connector.

    • Use a spudger to gently pry up the end of the logic board closest to the dock connector.

    • There is a small golden grounding tab on logic board adjacent to the 'do not remove sticker'. Be VERY careful this does not snag on the side of the case when prying up the logic board; it breaks easily. If you have signal problems after removing the logic board, check this ground tab.

    • If the board won't lift up, double check to make sure all the screws securing the logic board have been removed.

    Editar

  16. Slide the logic board towards the dock connector and out of the iPhone.

    • Slide the logic board towards the dock connector and out of the iPhone.

    • When replacing the logic board after installing battery, connect the camera to the logic board before inserting it into the case. Then make sure to set the top section of the logic board (where the SIM tray is) in place before settling the rest of the board in place. This is important, as sometimes the SIM card slot will not align into place. Once the top section is in place, the bottom section can be maneuvered into place. You will know the logic board is correctly installed when the SIM tray is aligned with the opening in the iPhone case and the camera module seats neatly into its place.

  17. Use a spudger to pry the battery up from the rear case. The battery is attached with an adhesive strip around the perimeter of the battery.

    • Use a spudger to pry the battery up from the rear case. The battery is attached with an adhesive strip around the perimeter of the battery.

    • To prevent the battery from bending during the removal process, we recommend against using just the plastic pull-tab.

    • Removing the battery is NOT necessary for replacing the GPS antenna. It merely gives you more space for removing the headphone assembly (which is also unnecessary to completely remove).

    • The iPhone's battery is attached to the rear case with a mild adhesive. This adhesive usually comes out attached to the battery. If your replacement battery already includes an adhesive backing, you're all set. If your replacement battery doesn't have an adhesive backing, you'll want to transfer the adhesive from your old battery to the new one.

    • If the battery isn't detaching from the rear case, apply a few drops of high concentration (over 90%) isopropyl alcohol under the edge of the battery. Wait about one minute for the alcohol solution to weaken the adhesive. Use the flat end of a spudger to gently lift the battery. Allow the alcohol to air dry before installing your new battery.

    • Don't try to forcefully lever the battery out. If needed, apply a few more drops of alcohol to further weaken the adhesive. Never deform or puncture the battery with your pry tool.

    • You can use a hair dryer or heat gun on its lowest setting to heat the back of the case. This will help loosen the adhesive bond before using the spudger to separate the battery from the case back.

    • Caution: Overheating the iPhone may ignite the battery.

    • Gently pull the power button electronics away from the top edge of the rear case.

    • Use the tip of a spudger or your fingers to remove the power button from the rear case.

    • The power button is attached to a metal handle. It can rotate 180º in one side and 135º in the other. When putting it back remember to rotate 180º so that the metal handle faces down (towards the back panel).
