Installing iPhone 5 display 

Step 1 — Front Panel Assembly 

Before disassembling your iPhone, be sure it is powered off.

Remove the two 3.6 mm Pentalobe screws next to the Lightning connector.

[topaccessory2u-blog]

Step 2 

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.

[topaccessory2u-blog]

Step 3 

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.

[topaccessory2u-blog]

Step 4 

Continue to pry up around the sides of the front panel assembly, detaching the clips along the left and right side.

[topaccessory2u-blog]

Step 5 

Once the clips have been released on the bottom and sides of the front panel assembly, pull the bottom of the assembly away from the rear case.

Do not try to completely remove the front panel assembly from the rear case, as there are several ribbon cables still attached at the top of the iPhone.

Lift and rotate the front panel assembly up to about 90 degrees from the rear case.

[topaccessory2u-blog]

Step 6 

Remove the following screws securing the front panel assembly cable bracket to the logic board:

Two 1.2 mm Phillips screws

One 1.6 mm Phillips screw

[topaccessory2u-blog]

Step 7 

Remove the front panel assembly cable bracket from the logic board.

[topaccessory2u-blog]

Step 8 

Use a plastic opening tool to disconnect the three front panel assembly cables:

Front-facing camera and sensor cable

Digitizer cable

LCD cable

[topaccessory2u-blog]

Step 9 Remove the front panel assembly from the rear case.

[topaccessory2u-blog]

Step 10 — Earpiece Speaker

One 4.1 mm Phillips screw

One 2.2 mm Phillips screw

[topaccessory2u-blog]

Step 11 

Remove the earpiece speaker bracket from the display assembly.

[topaccessory2u-blog]

Step 12 

Remove the earpiece speaker from the iPhone.

[topaccessory2u-blog]

Step 13 — Front-Facing Camera and Sensor Cable Starting under the earpiece speaker contacts, use a plastic opening tool or the tip of a spudger to pry the front facing camera cable out of the display assembly.
