Introdução
Use this guide to replace the home button in a 12.9" iPad Pro.
The original home button is uniquely paired to the logic board at the factory. If you replace the home button, Touch ID will not function.
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.
Parts of this guide were shot with a Wi-Fi model and as such, the internals may look slightly different from the LTE model. The procedure is the same for both models except where noted.
O que você precisa
-
-
Completely power down your iPad before you begin.
-
If your screen is cracked, lay overlapping strips of clear packing tape over the iPad's screen until the whole face is covered.
-
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.
-
-
-
As you slice through the adhesive, note the following:
-
The top has a large patch of thick adhesive. You'll need to slice 1/2" deep in order to cut the adhesive.
-
Don't slice deeper than 2 mm along the long edges of the iPad, or you risk damaging the display panel.
-
The lower edge also has thick patches of adhesive, but there are delicate flex cables in each corner. Don't slice deeper than 1/4" around the lower corners.
-
-
-
Heat an iOpener and lay it over the left edge of the iPad to soften the adhesive holding the screen in place.
-
Wait two minutes for the adhesive to soften before proceeding to the next step. The edge should be slightly too hot to the touch.

Yes. If you take the iPad apart most of the adhesive on the screen won’t be usable again. You can use either the specific kit for your ipad Pro that iFixIt sells, or get a roll of “red” tape (probably between 2-5mm size) and cut out pieces for all four side of the screen. You will probably also need tape or glue (such hot glue or something like B-7000) for the home button, and the metal bracket that holds the home button, since the old adhesive tends to not work a 2nd time.
Some LCD Assemblies come with Adhesive pre-applied, simply peel and seal. :)
Otherwise, plan on running some double-sided 3M tape before commencing new LCD Assembly Installation.
TIP: B7000 Adhesive in the bottom left and right corners will help keep it in place moving forward.
Replaced LCD and reattached home button, everything works, but the home button is lose and trying to fall inside, like it's missing something that is suppose to be between the home button and the cover that sets over it under the glass. The cover is stuck to the glass, but there's enough of a gap that the home button wants to fall inside?
I have the same issue, haven’t solved it yet but here is what I’ve found so far:
The home button appears to have several pieces not just one, including: 1. black gasket, 2. white or space-grey ring (paper or plastic?) around the metal part, 3. The actual glass circle button with fingerprint feature, and 4. electronics layer behind it.
When I took the button off, and re-adhered the button, the glue or tape between No. 2 and 3. above started to separate. Not sure how to put these back together since so small.
