Power off your iPhone 4S

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

Remove the back plate

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

  1. Set them aside. They are both the exact same size and length so it does not matter if you mix them up. They are interchangeable.
  2. 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

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

  1. These screws are different lengths so make sure you remember which one goes where. The one that is slightly larger is the bottom screw.
  2. 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.

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

  1. 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.

  1. Once you've gotten the battery pulled out of the iPhone 4S we can move on to inserting the replacement battery.

Remove the top logic board shield

The camera cable is protected by the top silver logic board shield. To replace it, we'll need to remove that shield for a few minutes.

  1. Remove the 4 screws labeled in the picture below using your #00 Phillips screwdriver making sure you remember which screw came from where as they are all different sizes.

  1. Use your spudger tool to carefully pry up the shield. There is a tiny clasp at the bottom of the shield. You'll need to make sure you push the top of the shield down a bit so it slides out. Once it does you can pull the shield out of the iPhone.

  1. Set the shield aside for a few minutes.

Replace the rear camera assembly

Now that the new camera assembly is secured into place on the logic board, we can go ahead and replace the shield.

  1. You will notice that there are little teeth on the left hand bottom side of the shield. These slip into the shield on the left side of the logic board. Line them up and carefully place back down the shield.
  2. Make sure the clasp to the right lower side of the logic board is also positioned underneath the cables and into the groove. All the screw holes should also be lined up at this point.

Replace the battery and grounding clip

  1. Pay attention to how the cable is bent on your old battery and if the new one is not crimped in the same fashion put the folds in it before inserting it into the iPhone 4S.

  2. Replace the two screws you removed in a prior step starting with the top one using your #00 Phillips screwdriver. Make sure the grounding clip stays positioned. Use your other hand to hold it straight while you replace the top screw if you need to.
