Video de nuestro cliente Sheldon Howe reemplazando la pantalla en su Apple iPhone 4Turn off the phone and remove the SIM card
The front assembly contains the frame, the glass digitizer and the LCD screen. We highly recommend
replacing the entire front assembly if any of these components need replacing.
Turn off the phone by holding the power button and confirming shutdown on screen using the Apple
approved sim removal tool. Pop the SIM card out and set it aside
Magnetic screwdriver
A magnetic bit screwdriver is a must for this job but did you know you can make 80's screwdriver magnetic
simply hit and rub the tip of the screwdriver against a powerful magnet to temporarily magnetize your
screwdriver. It will eventually demagnetize. At which point you can repeat the procedure
Remove the back cover
Using your Phillips screwdriver. Remove the two bottom screws. Set the two screws aside. Then gently
slide the back cover up about three mm. Then pull up from the top edge
Draw a map of components
In order to remove the front assembly most major components will have to come out we highly
recommend the draw map of screws and components down on a piece of paper. Then lay your
screws on that map as you go along. Here we just remove the battery connector screw. As well
we'll keep this virtual map of screws and components up throughout the disassembly and
reassembly process will. Mark every present screw in the component green and every absent one
red As you can see the battery screws are ready to remove so here on the map we have the frame
then every screw that will need to be removed that is directly visible right now the battery speaker
box, camera, vibrating motor logic board and a couple of fastening Shields we will also be removing
screws under the component which will be shown on the
map during that step
Remove the battery
We recommend removing the battery first it is glued in so something like a putty knife or any other flat
wide tool will be very handy. Put the putty knife underneath the provided battery removal tab and gently
pry up while pulling on the battery tap. Set the battery aside
Remove the shields
Remove a little odd shape piece near the battery mount and place it on the map. Go ahead and remove
the screw of the first fastening shield. Put the screw on the map. Then remove the second screw off the
same shield. Set both the screw and the shield on the map
Remove the vibrating motor
We will then go ahead and remove the vibrating motor right screw, then the left screw and the vibrating
motor set both of them on the map. The vibrating motor connects via contact pins so there is no
connectors or cables to remove
Open all connectors, remove the speaker box, camera and logic board
Then remove a logic board screw which will be covered by a wide circle. That white
circle is a water damage indicator which is used to determine whether the phone was
subjected to water exposure then using your flat screwdriver pop open the middle connector
and peel the flex cable up then disconnect the Wi-Fi antenna cable from the logic board.
Go ahead and remove the two screws securing the speaker box Then remove the speaker box.
Then using your flat bit remove the last screw securing the logic board in place Then using the
same flat bit gently pick open the connectors which tie the peripherals from all over the phone into
the logic board. These four connectors are best picked from the right side. The next two connectors
are for the LCD and the digitizer those are best picked from the bottom edge. And finally the camera
connection is best picked from the right side. Once all the connectors are open remove the camera.
At this point the logic board can be removed. Ensure that all the connectors are not in the way and
pick the logic board from the bottom edge and lift up ensuring nothing is getting caught. Set the logic board aside
Remove top fastening shield
Then proceed on removing the top fastening shield screws a total of five screws holding in place most
of the screws are different size and are unique to their place so make sure they land on the correct spot
on the map. Once you remove five screws the upper shield can be removed. You may need to slide it
down about a millimeter to pop it off its brackets on the bottom edge. Set the shield on the map
Open connectors, remove the speaker box, camera and logic board
Then remove a logic board screw which will be covered by a wide circle. That white circle is a water
damage indicator which is used to determine whether the phone was subjected to water exposure.
Then using your flat screwdriver pop open the middle connector and peel the flex cable up. Then
disconnect the Wi-Fi antenna cable from the logic board. Go ahead and remove the two screws securing
the speaker box Then remove the speaker box. Then using your flat bit remove the last screw securing
the logic board in place Then using the same flat bit gently pick open the connectors which tie the
peripherals from all over the phone into the logic board. These four connectors are best picked from
the right side. The next two connectors are for the LCD and the digitizer those are best picked from
the bottom edge. And finally the camera connection is best picked from the right side. Once all the
connectors are open remove the camera. At this point the logic board can be removed. Ensure that
all the connectors are not in the way and pick the logic board from the bottom edge and lift up ensuring
nothing is getting caught. Set the logic board aside
Remove 10 screws
Now only 10 more screws separate us from removing the front assembly. There are four tiny
screws in every corner and six more screws with washers three on each side of the frame.
Once all the screws have been removed and documented you can proceed on removing the
front assembly
Remove the front assembly
It is glued in place at the top and the bottom edges. At this point we recommend using a putty knife
or a case opening tool to separate the front assembly. Start at the bottom edge and gently move
along the perimeter lifting the front assembly from the mid frame. Make sure to route the LCD on the
digitizer connectors through the frame before fully separating the front assembly
Install the new assembly
Now we can go ahead and reinstall the new front assembly. Make sure to remove the protective
plastic from the bottom of the LCD then route the connectors back through the frame. It is very
important to pull the connectors through all the way otherwise you will not be able to reconnect
them on the logic board properly Pay extra attention that nothing is getting caught and that both
connectors are aligned with each other. Squeeze the top and the bottom edges on the front assembly
to catch the adhesive
Replace the six screws
Replace the six side screws ensuring that the washers are present on all of them. Then replace the
four corner screws
Replace the logic board, speaker, camera
Readjust the connectors and proceed on replacing the logic board. Slide it in from the bottom
top edge goes down. First ensure that the board is in proper alignment with the mounting holes.
Then replace the speaker box. Make sure that the left mount slides under the logic board and
that the Wi-Fi antennas flush with a frame. Then replace the two screws and reconnect the
Wi-Fi cable to the logic board. Then using the flat screwdriver replace the top right logic board
screw. Then replace the camera and plug it in. Then replace the screw that was
under the water damage indicator you may also replace the water damage indicator if needed.
Then secure the remaining 5 connectors to the logic board. Each one makes fairly distinctive click
when plugged in properly
Connect the cables, replace parts, secure fastening shields
Replace the top fastening shield. It needs to slide from the bottom in order to catch its mounting
bracket once. The shield is properly aligned replace the five screws holding it in place. Then you
can reconnect the middle connector which ties in the dark port to the motherboard. Then replace
and secure the vibrating motor. Then replace the final fastening shield and two screws. Then replace
the odd shape piece near the battery connector This piece connects the battery ground to the
back cover to provide better shielding and to diminish wireless signal noise. At this point you can
reconnect the battery. We recommend plugging in the connector then simply
dropping the battery in its bay. Then secure the battery connector screw
Replace the back cover
Now you can replace the back cover put it down about three millimeter offset from the bottom
edge then slide it down in place then replace your bottom two screws replace the SIM card and
finally remove the screen protector from the new
