Apple iPad 4

DISASSEMBLING PROCEDURE 
LCD Screen removal 
Before starting to disassemble the iPad 4, we need to bring to your attention an area where the need for extreme caution is necessary to prevent irreversible damage.
On the left side of the tablet, approximately 2 inches from the bottom, is the touch screen digitizer ribbon cable. When you are separating the touch screen from the bezel with the plastic opening tool below in Step Three, make sure to avoid using excessive force on that part of the tablet.

Utilizing the heat gun or blow dryer, commence heating the outer edges of the tablet to soften the adhesive that is securing the front panel to the unit. Normally 1-2 minutes will suffice.

Using the plastic opening tool, begin to create separation between the trim bezel and the touch screen digitizer.
Start sliding the opening tool around the display assembly to release the adhesive around the entire tablet.
The support of the heat gun or blow dryer might be needed to continue softening the adhesive while working all the way around the touch screen digitizer.

When the adhesive has been released all the way around the tablet, rotate the touch screen away from the base. This will be similar to opening a book. Make sure you are mindful of the ribbon cable in the bottom left corner.

Locate and remove the four small Phillips screws (#00) that secure the LCD screen to the base.

Raise and rotate the LCD screen out of the base the same way as you did the touch screen digitizer. You can then rest the LCD screen on top of the digitizer.

The LCD screen ribbon cable is held in place with a FPC style connector that has a locking tab. Unlock this tab before trying to unplug the ribbon cable.
The lock is the tab on the opposite side of where the cable is inserted. Utilizing the spudger, flip the tab up 90 degrees to release the ribbon cable. Once the locking tab is flipped upward 90 degrees, slide the ribbon cable out from its connector. This will allow you to remove the LCD screen from the iPad 4.

Touch screen removal 

The touch screen digitizer ribbon cable is held in place with the same locking style connectors as the LCD screen (see previous step). You need to unlock these tabs before attempting to unplug the ribbon cables. When the locking tabs are flipped upward 90 degrees, slide the ribbon cables out from their connectors.

The home button ribbon cable is attached by a smaller version of the same locking sockets; do not forget to unlock the tabs. Unplug the small cable before removing the touch screen.

Home Button removal 

Using the heat gun or blow dryer, heat the area of the home button to soften the adhesive that secures the home button to the touch screen digitizer. Normally 1-2 minutes will suffice.

Utilizing the plastic opening tool, separate the home button assembly from the touch screen digitizer. The most efficient way to do this is by sliding the plastic opening tool under the assembly and prying up gently. This needs to be done on both sides of the assembly. You can now remove the home button assembly from the touch screen digitizer.

Continuing with the plastic opening tool, slide it underneath the home button retainer to release the adhesive carefully. You can now remove the home button from the
 touch screen digitizer.

Front Facing Camera removal 

Using the spudger, unplug the push style plug for the camera by lifting it up and out of its socket. Still working with the spudger, pry the camera out of its socket/housing and remove it from the iPad 4.

Port/Connector removal 

Slide the spudger under the plastic spacer located by the Wi-Fi antenna and lightening connector cable. Separate the spacer from the adhesive that is keeping it secured to the iPad 4. You can now remove the spacer from the iPad 4.

Utilizing the spudger, pry up gently on the dock connector cable to release it from its push style plug socket.

Locate and remove the two small Phillips screws (#00) that secure the lightening port/connector into the iPad 4. You can now remove the lightening port/connector from the iPad 4.

Wi-Fi Antenna removal 

Using the spudger, pry the connectors for the speaker and Wi-Fi antenna from their sockets.

Locate and remove the four small Phillips screws (#00) that secure the Wi-Fi antenna into the iPad 4.

Continuing with the spudger, release the Wi-Fi antenna from the speaker below it. You can now separate the speaker and Wi-Fi cables from each other to remove the Wi-Fi antenna from the iPad 4.

Battery removal 

Locate and remove the four small Phillips screws (#00) that secure the motherboard assembly into the iPad 4. Once the screws have been removed, separate the motherboard assembly from the iPad 4. Slide the spudger or metal opening tool under the battery to begin separating the battery from the metal case of the iPad 4. The adhesive is very strong so be sure to take your time during this step. Once you have worked your way all the way across the bottom of the battery and separated the adhesive, remove the battery from the iPad 4.
