Introduction
Use this guide to replace the home button in an Apple 12.9" 2nd Gen iPad Pro.
Note that the home button installed in your original screen is paired to the iPad's logic board, and will need to be removed and transferred to a new screen to retain Touch ID functionality.
The home button attaches to the screen with an adhesive gasket. You’ll need some liquid adhesive to glue the home button to the display.
This guide is written for the Wi-Fi model. If you have the cellular model, you’ll need to do some additional disassembly (not noted in this guide).
Some photos show the battery connector blocked with two card strips. While this is an optional method, it's more reliable to fully discharge the battery. Ignore this visual discrepancy as you work through the guide.
You’ll need replacement adhesive to reattach components when reassembling the device.

-
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.
-
Do your best to follow the rest of the guide as described. However, once the glass is broken, it will likely continue to crack as you work, and you may need to use a metal prying tool to scoop the glass out.

Outil utilisé dans cette étape :Halberd Spudger$2.99
-
As you slice through the adhesive, note the following:
-
The adhesive on the long edges of the iPad is about 4 mm wide. Avoid slicing deeper than that, or you risk damaging the display panel.
-
The adhesive on the short edges of the iPad is about 2 mm wide. Avoid slicing deeper than that.
-
Take especially care when slicing near the home button and charging port to avoid damaging the flex cables.
-
Take extra care when you slice near the front facing camera, to avoid damaging or smearing it.
-
-
-
Apply a heated iOpener to the left edge of the screen to loosen the adhesive underneath. Apply the iOpener for at least 5 minutes.
-
-
Outil utilisé dans cette étape :Clampy - Anti-Clamp$24.95
-
Pull the blue handle backwards to unlock the Anti-Clamp's arms.
-
Place an object under your iPad so it rests level between the suction cups.
-
Position the suction cups near the middle of the left edge—one on the top, and one on the bottom.
-
Hold the bottom of the Anti-Clamp steady and firmly press down on the top cup to apply suction.
-
-
-
Wait one minute to give the adhesive a chance to release and present an opening gap.
-
If your screen isn't getting hot enough, you can use a hair dryer to heat along the left edge of the iPad.
-
Insert an opening pick under the screen when the Anti-Clamp creates a large enough gap.
-
Skip the next two steps.
-
-
-
Once the screen is warm to touch, apply a suction handle to the left edge of the iPad's screen, above the Smart Connector port and as close to the edge as possible.
-
-
-
While holding down the corners of the iPad, repeatedly pull up on the screen, then ease it back down to weaken the adhesive. This will eventually create a small gap in the seam.
-
Once you've created a small gap, insert the tip of an opening pick into the gap.
-
-
-
Reapply the iOpener to the bottom left corner of the iPad for at least 2 minutes, spanning from the opening pick to the home button.
-
After letting the adhesive soften, insert an opening pick or halberd spudger into the gap next to the opening pick.
-
Use an opening pick or halberd spudger to slice the adhesive along the bottom left side of the iPad. If the slicing becomes difficult, reheat the edge and try again.
-
-
-
Insert an opening pick underneath the bottom left corner of the screen to prevent the adhesive from resealing.
-
-
-
Reapply the iOpener to the upper left corner of the iPad for at least 2 minutes, spanning from the opening pick to the front facing camera.
-
Use an opening pick or halberd spudger and slide along the upper left edge of the iPad to slice the adhesive.
-
-
-
Insert an opening pick underneath the top left corner of the screen to prevent the adhesive from resealing.
-
-
-
Reheat your iOpener and apply it the top edge of the device for at least 2 minutes.
-
Use an opening pick or halberd spudger and slide along the top edge of the iPad to slice the adhesive. Stop before you reach the front-facing camera.
-
-
-
-
Insert an opening pick underneath the screen just before the front-facing camera to prevent the adhesive from resealing.
-
-
-
Reheat your iOpener and apply it to the top edge of the device for at least 2 minutes.
-
Insert an opening pick or a halberd spudger just past the front-facing camera.
-
Use your cutting tool to slice the remaining adhesive underneath the top edge of your device.
-
-
-
Insert an opening pick underneath the upper right corner of the screen to prevent the adhesive from resealing.
-
-
-
Apply a heated iOpener to the right edge of the screen for 5 minutes to loosen the adhesive underneath.

Slide the opening pick along the bottom edge of the iPad, stopping short about 12 mm before reaching the home button.
-
-
-
Insert an opening pick underneath the screen just before the home button to prevent the adhesive from resealing.

Use the tip of an opening pick or an halberd spudger to slice the adhesive beneath the home button.
-
-
-
Insert an opening pick or a halberd spudger just past the home button.
-
Use your cutting tool to slice the remaining adhesive underneath the bottom edge of your device.
-
-
-
At this point, you've sliced through most of the screen adhesive. Use an opening pick to carefully slice any remaining adhesive along the edges until the screen is freed.
-
-
-
Lift up the upper edge of the screen and slide the entire screen towards the front-facing camera to access the iPad's internal components.
-
Use masking tape to tape the lower edge of the screen to the frame to prevent the screen from slipping.
-
-
-
Attach a long strip of masking tape to the top edge of the screen. Fold the tape over the edge and make sure that the tape is attached securely.
-
Attach the other end of the strip to the bottom edge of the iPad frame to hold the screen at an angle. Make sure the tape attaches securely to the frame.

If possible, turn on your device and test your repair before installing new adhesive and resealing.
Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.
To reassemble your device, follow these instructions in reverse order.
During reassembly, apply new adhesive where it's necessary after cleaning the relevant areas with isopropyl alcohol (>90%).
Take your e-waste to an R2 or e-Stewards certified recycler.
