Remove the nine 4.0 mm Phillips #00 screws securing the midframe to the display assembly.

Passo 7

The midframe is secured to the display assembly by several plastic clips behind the chrome bezel of the midframe. The next few steps will guide you through separating the clips to free the midframe.
Starting on the volume button side of the phone, insert your plastic opening tool between the chrome bezel around the display glass and the larger chrome border piece. Look for the seam between the two.
Slide the opening tool along the seam, separating the plastic clips as you go.
Be very gentle whilst prying, and pry only enough to separate the plastic clips—there are several thin points in the midframe bezel that may crack if you bend them too much.

Passo 8

Continue prying around the corner of the phone.
Slide your opening tool along the seam between the midframe and display along the bottom of the device, releasing more of the plastic clips.

Passo 9

Again, pry around the corner, to the power button side.
Slide the opening tool along the seam.

Passo 10

Continue sliding the opening tool around the top of the phone, releasing the last of the clips and freeing the midframe from the display assembly.
At this point, you may want to run your plastic opening tool along the entire perimeter of the device again, to make sure you've released all of the plastic clips.

Prepare an iOpener (or use a hair dryer or heat gun) and heat the screen side of the phone to loosen the display adhesive.

Passo 20

Ferramenta utilizada neste passo:

Jimmy

$7.95

Comprar

Because the gap between the screen and phone frame is so thin, a Jimmy is needed to separate the two. Read the following warnings carefully before proceeding.
Even though the metal blade is mostly dull, be careful not to apply too much pressure, as this might cause the Jimmy to slip and cut you or damage the phone.
Wear eye protection. The glass may break, sending pieces flying.

Passo 21

With the adhesive lose, insert the blade into the small gap between the frame and the screen, near the volume rocker.
Slowly slide the blade down the length of the phone towards the charge port to release the screen glass from the LCD.
The glass will most likely develop hairline fractures as you bend it during this step. Make sure you have proper eye protection.

Passo 22

The next three steps involve removing extremely fragile components. Consider working on a surface that will be easy to clean up afterwards.
With the screen glass completely loosened around the edges, remove it from the phone.
The fragile LCD display underneath the glass has a tendency to shatter into small pieces. If in doubt, protect your hands with gloves.
Cover the LCD with tape to prevent the broken glass from spreading or falling out during removal.
