Power off your iPhone 4S

Before performing any repair you should always power off your device before opening it up.

Remove the back plate

Using your security screwdriver, remove the 2 screws on either side of the dock connector port.

Gently slide up the back plate by applying a bit of pressure along the bottom with your thumbs and sliding upwards.

Remove the battery and grounding clip

Using your #00 Phillips screwdriver, remove the two screws holding the battery in place.

Remove the battery and grounding clip

These screws are different lengths so make sure you remember which one goes where. The one that is slightly larger is the bottom screw.
There is a tiny grounding clip underneath the battery clip where the first screw is located. Use your spudger tool or finger to remove it before prying the clip up. Many times it can go flying if you don’t remove it first and then you’ll have difficulty locating it so it’s best to remove it first.

Remove the battery and grounding clip

Now use your spudger tool and at the bottom of the battery clip, gently pry upwards so the clip pops up.

Move to the edge of the iPhone where the volume buttons are located and use your spudger tool to carefully pry up the battery. It is stuck down with a good amount of adhesive so be careful when prying upwards that you don’t bend the battery. This is why I do not use the plastic tab that is provided. It typically rips or bends the battery. If one part is resistant move your pry tool a little further down and gently start prying it up in different places taking care not to come too close to the volume button cables towards the top.

Remove the top logic board shields

Using your #00 Phillips screwdriver, remove the four screws that hold the top silver shield in place and the one screw that holds the small black shield in place.come too close to the volume button cables towards the top.

Unclip the top logic board cables & remove the rear-facing camera

Using your spudger or pry tool carefully disconnect all the cables at the top of the logic board. There are seven cables in total. One of the cables lies underneath the bottom-most cable so you’ll need to disconnect the cable over it before folding it back and revealing the shorter cable underneath.

Disconnect the dock connector

Using your #00 Phillips screwdriver remove the shield that is covering the dock connector cable towards the middle left of the iPhone. Remember which screw came from where, as they are different sizes. Gently lift the shield out of the iPhone and set it aside.

Pry up the cellular antenna

Using your spudger tool carefully pry up the round connection for the cellular antenna. It should come up easily so pry up gently.

You’ll notice that it is wrapped around a metal clip. Gently unwrap it so it’s sticking upwards and leave it in this position.

Remove the SIM card and tray

Using a SIM removal tool or a bent paper clip, eject the SIM tray and set it, and the SIM card aside.

Remove the three #00 Phillips screws at the top, middle, and bottom left of the logic board with your #00 Phillips screwdriver.

The top screw has a piece of tape over, it you’ll need to peel back.

After removing it you’ll also notice a gold grounding clip underneath it. Make sure you don’t lose it as you’ll need it for reassembly.

There are two more screws holding the logic board in place and you’ll need to remove them with your flat head screwdriver. They are located at the top right and bottom of the logic board.

Now you should be able to lift the logic board out of the iPhone. Use the area that the rear-facing camera was located and the bottom of the logic board to lift it straight out.

Remove the loudspeaker assembly

The loudspeaker is held in with two screws that are located on both sides of the assembly. Use your #00 Phillips screwdriver to remove them.

The vibrator assembly is only held down with a bit of adhesive. Use your pry tool or metal spatula tool in order to loosen the adhesive and remove the vibrator assembly. Just make sure you are careful not to bend it.

Remove the digitizer and LCD assembly

Hold the iPhone so the screen is facing you and insert your pry tool or metal spatula into the top left corner and slowly start breaking the adhesive underneath the display by moving your tool gently back and forth.
Once the top left is free, move over to the top right corner and repeat.
After the top of the assembly is free, move towards the bottom on either side of the Home button and repeat the same process.
Once all the adhesive is broken, carefully pull the front assembly off the iPhone taking care to make sure the digitizer and LCD cables don’t get caught up in the frame.
Transfer the Home button, speaker mesh, & camera hold to the new digitizer & LCD assembly
