iPhone 4S Screen Replacement

Power off your iPhone 4S

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

Removing screws in iPhone 4S

Remove the back plate

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

Lifting up the battery case in iPhone 4S

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

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.

Disconnecting cables in iPhone 4S

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 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.

Removing dock connector screw in iPhone 4S

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.

Prying up cellular antenna in iPhone 4S

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 sim card and tray

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.

Removing logic board screws in iPhone 4S

Remove the logic board

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.

Removing loud speaker screws in iPhone 4S

Remove the loud speaker assembly

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

Remove the vibrator assembly

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

And …done!

Now that you’ve completely reassembled your iPhone 4S you can go ahead and hold down the power button in order to turn it back on. After it boots up, test the new assembly by dialing some numbers, using the keyboard, and looking for dead pixels. Then place a test call, check vibrator functionality, and do an all around test to make sure all of the components you had to remove and replace are in good working order.

If everything is back in working order, pat yourself on the back. This isn’t an easy repair to perform and if you were successful, you’ve now unlocked the ninja DIY’er achievement!
