Apple iPhone 5c: front panel replacement procedure
Remove
the two 3.8 mm Pentalobe screws next to the Lightning connector.
The
next two steps demonstrate using the iSclack, a great tool for safely opening
the iPhone 5c that we recommend for anyone doing more than one repair on an
iPhone 5, 5s, or 5c. If you aren't using the iSclack, skip to step 5. Close the
handle on the iSclack, opening the suction-cup jaws. Place the bottom of your
iPhone in between the suction cups, against the plastic depth gauge.
The
top suction cup should rest just above the home button. Open the handles to
close the jaws of the iSclack. Center the suction cups and press them firmly
onto the top and bottom of the iPhone.
Hold
onto your iPhone securely and close the handle of the iSclack to separate the
suction cups, pulling the front panel up from the rear case. The iSclack is
designed to safely open your iPhone just enough to separate the pieces, but not
enough to damage any cables. Peel the two suction cups off your iPhone.
Press
a suction cup onto the screen, just above the home button. Be sure the cup is
completely on the screen to get a tight seal.
Make
sure the suction cup is firmly attached to the front panel assembly. While
holding the iPhone down with one hand, pull up on the suction cup to slightly
separate the front panel assembly from the rear case. Take your time and apply
firm, constant force. The display assembly is a much tighter fit than most
devices. With a plastic opening tool, begin to gently pry the rear case down,
away from the display assembly, while you pull up with the suction cup. There
are several clips attaching the front panel assembly to the rear case, so you
may need to use a combination of the suction cup and plastic opening tool to
free the front panel assembly.
Pull
the plastic nub to release the vacuum seal on the suction cup. Remove the
suction cup from the display assembly. Lift the home button end of the front panel
up to gain access to the connectors near the top of the phone. During the next
few steps, until you remove the front panel assembly, keep it supported at a
90ยบ angle in relation to the rear case.
Remove
the following Phillips #000 screws securing the front panel assembly cable
bracket to the logic board:
Two
1.3 mm screws
One 1.7 mm screw
One 1.7 mm screw
One 3.25 mm screw It is especially important to keep track of your screws in
this step for reassembly. Accidentally using the 3.25 mm screw or the 1.7 mm
screw in the bottom right hole will result in significant damage to the logic
board causing the phone to no longer boot properly. Be careful not to
over-tighten the screws. If they don't fit easily when you are securing them,
they may be the wrong size, don't force them.
Remove
the front panel assembly cable bracket from the logic board.
Use
a plastic opening tool to disconnect the front-facing camera and sensor cable
connector. Be sure to only pry up on the connector, and not on the socket on
the logic board.
Use
a plastic opening tool to disconnect the LCD cable connector. The LCD and
Digitizer connectors are on the same cable assembly, so prying the LCD
connector up should disconnect both connectors. Double check that the two
cables are fully disconnected before removing the display. When reassembling
your phone, the LCD cable may pop off its connector. A blank screen, or white
lines on the display could be caused by a loose connection. Should this happen,
reconnect the cable and power cycle your phone. The best way to power cycle
your phone is to disconnect and reconnect the battery.
Remove
the front panel assembly from the rear case.
Remove
the two 1.3 mm Phillips #000 screws securing the home button bracket to the
display assembly.
Use
a plastic opening tool to pry the edge of the home button ribbon cable up from
the display assembly.
Start
under the contact points on the right and work to the left. Starting from the
left and going right may rip your ribbon cable. The contacts are well adhered
to the front panel and should be peeled up first.
If you have trouble sliding the plastic opening tool under the contact points, flip the tool over and gently push against the right side of the contact cable to loosen the adhesive, then try again.
If you have trouble sliding the plastic opening tool under the contact points, flip the tool over and gently push against the right side of the contact cable to loosen the adhesive, then try again.
Remove
the home button ribbon cable from the display assembly.
Gently
push the top right corner of the home button up away from the front panel. Do
not push the home button all the way through; you only need to get a corner
free so that you can pry it out with a spudger. This membrane is very thin. If
you feel like you are going to tear the button, apply heat and try again.
Peel
the home button the rest of the way off of the display by prying gently with a
spudger. Remove the home button assembly from the front panel.
Remove
two Phillips #000 screws securing the upper component bracket to the display
assembly.
One
4.2 mm screw
One 2.3 mm screw
One 2.3 mm screw
Use
the flat edge of a spudger to push the earpiece speaker bracket off the display
assembly.
Remove
the earpiece speaker from the iPhone.
Using
the pointed end of a spudger, gently pry the earpiece speaker contact cable up,
to separate this portion of the camera and sensor cable from the adhesive
below. There is a small, square, plastic and metal holder for the proximity
sensor. This holder is essential for the proximity sensor to function
correctly. f replacing the proximity sensor make sure that the holder remains
adhered to the back of he display. If it comes off with the old proximity
sensor, remove it from the old sensor and use a tiny bit of adhesive to
re-attach it to the back of the display.
Slide
the point of a spudger under the microphone to lift it out of its recess in the
display assembly.
Remove
two 1.2 mm Phillips #000 screws from each side of the LCD frame (four total).
Remove
the 1.6 mm Phillips #000 screws from the LCD shield plate.
One
at bottom of the display assembly near the home button opening
One at the top of the display near the cables
One at the top of the display near the cables
Remove
the LCD shield plate from he display assembly. Display Assembly remains.
