Step 7. Remove the LCD shield
Remove the 7 Phillips screws from the LCD shield on top of the LCD panel.
The last one is near the home button assembly, from where you removed the metal cover.
Place the Phillips screws in the bowl labelled step 7.
Remember the connector IC, from which you removed the connector while removing the home button? That connector IC is affixed to the LCD panel with glue. Gently pry it open from the housing using your plastic pry tool.
Once the connector IC comes out of its housing, removing the LCD shield will become quite easy.
You have completed the process of removing the shattered LCD panel from your iPhone.
Reassembling the New LCD Panel
Step 8. Affix the shield to the new panel
Take the new LCD screen and pull off the protective sheath (if any).
Clean the LCD shield with the brush to remove any dust particles.
Place the shield on the new LCD screen.
Pick up the Phillips screws from the bowl labelled step 7.
Screwing them back into the LCD shield. The final screw will be near the home button assembly.
Adjust the IC back into the housing of the new LCD panel. There will be some glue left on the back, gently apply pressure with the flat part of your plastic pry tool.
Pick up the home button assembly from the bowl labelled step 6 and carefully place the home button in its cavity.
Gently place the flex cable extension on the 2 protrusions in the LCD panel.
Use the flat end of the plastic pry tool to press the rubber all around to fix it to the panel.
Put the connector back on the IC using the plastic pry tool.
Pick up the metal cover from the bowl and place it over the home button.
Fasten it in place with the 2 Phillips screws. The top-left screw is slightly longer than the bottom-right one.
Pick up the proximity front camera flex cable assembly from the bowl labelled step 5.
This step requires a lot of patience and cautiousness. If you recall, the entire assembly is affixed to the ear speaker rubber mat. Carefully place the rubber mat on the cavity of the ear speaker.
There is a small hole on top of the IC that will go on the protrusion beside the proximity sensor cavity.
Use the flat end of the plastic pry tool to gently affix it on the panel. Do not apply pressure on the IC, rather the surrounding area.
Make sure that it is affixed to the housing so your later steps are not mired in complications.
Gently put the flex cable, containing the proximity sensor along with the plastic bracket and the ambient light sensor along with the rubber gasket, in its designated place.
Use the pry tool to place both the sensors in their respective cavities, but do not press too hard as you are not supposed to affix them to their cavities.
Use the same plastic pry tool as a temporary holding device, as these sensors may easily slip out of their cavities. Although the proximity sensor plastic bracket may get affixed firmly with the housing holding the flex cable for you, but be cautious, just in case.
Step 10. Reattach the ear speaker and front camera
Pick up the ear speaker from the bowl labelled step 4 and place it on top of the ear speaker rubber.
It has a cavity that will fit perfectly with the protrusion on the backside of the ear speaker. Moreover, the reattached speaker will hold both sensors in place, even though it isn't glued.
Now pick up the front camera plastic ring from the bowl labelled step 5 and place it in the cavity of the front camera.
Use another pry tool to hold the speaker in place as you fix the front camera.
Now hold both the front camera and the flex cable on top of the ear speaker with the flat end of the plastic pry tool. Be sure that the small projections on the ear speaker overlap correctly with the cavities in the front camera flex.
Pick up the metal cover and place it over the assembly.
All 3 screws are different sizes. The one adjacent to the ambient light sensor is the largest and the one adjacent to proximity sensor is the smallest.
Fasten it in place with the 3 Phillips screws.
