Turn off your iPhone before you start the repair!

Remove your SIM card and tray. Then, remove these two pentalobe screws on the bottom of the device.

Step 2: Open backcover

Push the back cover up until you can remove it from the frame.

Step 3: Loosen screws and connector

Step 4: Remove cover

Remove these two screws and the metal cover they secure. Detach the big connector using with the spatula and carefully bend it to the side a little, so that it will not be in your way later on.

Step 5: Detach cable

Remove this connector from the logic board. Be careful not to damage the small blue chip next to it. Remove these two screws and the speaker module they secure. Set aside the little black plastic triangle, you will need reinstall it later.

Step 6: Remove metal cover

Remove these screws. Then, remove the metal cover.

Step 7: Remove metal clamp

The screw in the upper right corner will detach another small metal piece which you also need to keep safe for later. This screw underneath the metal cover is in itself a thread. Remove it as well.

Step 8: Detach flat cable

Detach all of these connectors from the logic board. Carefully pry them off with the plastic spatula and bend them to the side a little bit. Underneath the longer cable you will find another connector to remove.

Step 9: Remove camera module

Once you have removed the camera connector, remove the whole module. Underneath the LED flash there is another important screw. Remove it and set aside the metal piece it secures. You can now remove the logic board itself. Grab it near the bottom and carefully pull up and back.

Step 10: Remove vibration motor

Drive the flat end of the plastic spatula underneath the vibration motor in order to remove it.

Step 11: Loosen screws

Remove these four screws in the corners. Note: One of them may be hidden behind a small black sticker. Make sure to not accidentally remove the wrong screw!

Step 12: Remove display

Loosen these six screws along the inside of the frame. You do not need to remove them all the way. Remove the old display from the frame. Push down into one of the corners with the pointy end of the spatula. If necessary, insert the metal plectrum between display and frame to help loosen it.

Step 13: Insert new display

Remove the red protective film from the back of the replacement display. Carefully feed the two cables through the slit in the casing.

Warning: Be very careful not to bend the cables! See above for correct procedure!

Keep checking from the side to make sure they are straight and do not get trapped in between the new display and the frame. Otherwise they might break and your display will not work!

Step 14: Tighten the frame screws

Tighten these six screws on the inside of the frame. If the display will not fit properly, remove the screws completely. Make sure the screen is flush on all sides and that there are no gaps between display and frame.

Step 15: Tighten screws

Attach these four screws in the corners.

Step 16: Insert vibration motor

Reinstall the vibration motor.

In case it will not stick to the frame, cut a piece of double sided adhesive tape to size and attach it to the bottom of the motor.

Step 17: Insert mainboard and camera

Reinstall the logic board. Make sure none of the connectors are trapped underneath. Before reinstalling the camera module, attach the screw here in the corner. Make sure to reattach the small metal piece the correct way around. The longer side should face down, stuck between logic board and frame. The shorter side with the hole should point down towards the dock connector. Now you can reinstall the camera module and attach its connector to the logic board.

Step 18: Attach flat cable

Then, reattach the five small connectors and the two cables coming from the new display. If one of the cables seems too short, it is probably stuck between display and frame.

Warning: Do not pull the cable as it might rip. Rather, disassemble the device and make sure, the cables are fed straight through the slit in the casing.

Step 19: Fix mainboard

Secure the logic board with these screws. Start with this slot screw. Do not forget the metal piece from the upper right corner. It is secured with a screw which uses the one below it as a thread.

Step 20: Fix metal cover

Reattach the metal cover and the remaining screws.

Step 21: Fix speaker

Reinstall the speaker and secure it with two screws. Reattach the small antenna cable (again, look out for the small blue chip!). Place the small black plastic triangle onto the thread on the left after you have installed the speaker.

Step 22: Attach flat cable

Carefully bend the large cable back into place and attach it to the logic board. Secure it with a metal cover and two screws.

Step 23: Insert battery

Reinstall the battery. Attach the small metal piece and secure it with the connector and two screws.

Step 24: Fasten backcover
