Introduction

Note: this guide is for the LTE version only. For the Wi-Fi version, click here.

The button control cable has the lock button and volume buttons integrated within it. You’ll need to replace the entire cable if any of those buttons are malfunctioning.

Be very careful when you isolate the battery using a battery blocker. The battery contacts are easily bent or broken, resulting in irreversible damage. If you choose to complete the guide without isolating the battery, avoid using metal tools except when completely necessary (like when removing screws) to prevent shorting the battery and damaging sensitive circuit components.

Some photos in this guide are from a different model and may contain slight visual discrepancies, but they won’t affect the guide procedure.

What you need

Step 1

              Heat the left edge

Heat an iOpener and apply it to the left edge of the device for two minutes.

Step 3

              Insert an opening pick

If your display is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken screen.
Once the screen is warm to touch, apply a suction handle to the left edge of the screen and as close to the edge as possible.
Lift the screen with the suction handle to create a small gap between the digitizer and the frame.
Insert an opening pick into the gap between the digitizer and the frame.

Step 31

              Remove the front panel assembly

Remove the front panel assembly.
Use an opening pick to cut away any residual adhesive that may still be connecting the front panel assembly to the frame.
If you experience “ghost” or “phantom” touch input issues with your new display, this can be resolved by adding a layer of very thin insulating tape, such as Kapton (polyimide) tape, to the highlighted areas on the back of the panel. iFixit replacement digitizers come with the proper insulation and should not require the addition of any tape.
Without the proper insulation, these areas of the digitizer can ground out against other components, causing touch input malfunction.
The insulation is not visible to the naked eye and is different from the foam dust barrier strips found on many iPads.
During reassembly, before installing a display, remove any remaining adhesive from the iPad, and clean the glued areas with high concentration isopropyl alcohol (90% or greater) and a lint-free cloth. This helps prep the iPad for fresh adhesive and ensures that it will bond properly.
Test your iPad’s functions and install pre-cut adhesive strips to the back of the display using our display adhesive application guide before sealing it up.
