Einleitung

The logic board of your iPhone controls everything in the iPhone.

    • 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.

    • Wear safety glasses to protect your eyes from any glass shaken free during the repair.

  2. dIuP4j5Qv31qVvWF

    • Remove the two Phillips #00 screws from the dock-connector end of the iPhone.

  3. ujMrsay6gwhMetEC

    • 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.

    • 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 thick, clear packing tape may be used.

    • 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. BUlIXcKQYB5vEPDr

    • 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."

  6. PLYsSmJJq2UOV5Mm

    • 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."

  7. jcAcUUSDwvGAoIgk

    • Use a spudger to flip up the white plastic tab holding the remaining ribbon cable 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.

    Is there a way of replacing the connector?

    i have torn the top of the connector......... would that be the reason that the iPhone would not start even though the ribbon is in the connector and fastened secured with the white plastic tab is down.

    HOW? My device display doesn't turns on (

    Make sure that the battery is charged up as the battery drains while the phone is off - i had this. And also the step 6 is very tricky while opening and while closing. make sure you have fixed all the tabs to their connectors. Also I got frustrated when my display didnt turn ON but I gave 24hours till i did anything so i cooled down-and next day I did it.

    • 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.

  9. gqZcREpGSIqiQErm

    • Carefully peel up the small sticker labeled "Do not remove."

    Il y a un risque de détruire l’autocollant : plus il est vieux, mieux la colle tient… J’ai eu du mal à l’enlever et j’ai dû le gratter. Mais ça n’a pas l’air d’être un souci si vous l’abîmez

    • 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.

    Should be Philips #000

    • Use a spudger to gently remove the camera retaining clip, (formerly secured by the removed screw) and 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.

  15. UbuxLCtleTRMqPAR

    • 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.

  16. QFGjHPFgRb5PSFZe

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

  17. CTXBCkZdftDFsUSP

    • Use a spudger to disconnect the camera from the logic board.

To reassemble your device, follow these instructions in reverse order.

Step 6: When I attempted to 'rotate the white connector 90 degrees' my white connector broke into 4 pieces... my phone is now beyond my repair. I feel soo dumb. I should have used a pair of eyebrow tweezers (two flat blades that press together) to wiggle the #3 ribbon cable in/out of the connector instead of trying to pivot it.

Anyone know how to repair this? Drop me a line at quathiaski(at)gmail.com

I have found out why I broke my connector all to heck... I attacked the wrong end with my plastic prodder. Work on the BLACK end... it moves...not the white end.

Dayna -

Hi Dayna, How are you today.

You are not dumb, you is learning.

Have a nice day :)
