Follow the steps in this guide to replace a faulty home button in an iPad mini 4 Wi-Fi.

Note that the original home button in this device is paired to the logic board, and swapping in a new button will disable Touch ID functionality.

    • Apply a suction cup halfway up the heated side.

    • Be sure the cup is completely flat on the screen to get a tight seal.

    • While holding the iPad down with one hand, pull up on the suction cup with strong, steady force to create a gap.

    • Depending on the age of your device, this may be difficult. If you have trouble, apply more heat and try again.

    • Be careful to only lift the glass enough to insert an opening pick—any more and you risk cracking the glass.

  3. iPad mini 4 Wi-Fi Home Button Assembly Replacement: passo 3, immagine 1 di 2 iPad mini 4 Wi-Fi Home Button Assembly Replacement: passo 3, immagine 2 di 2
    • While holding the glass up with the suction cup, insert the point of an opening pick into the gap between the glass and body of the iPad.

    • Don't insert the opening pick any deeper than 2 mm into the side of the display. Inserting the pick deeper than 2 mm could damage the backlight assembly, LCD display, or touchscreen.

    • Reheat and reapply the iOpener to the left edge for a few minutes.

    • Be careful not to overheat the iOpener during the repair procedure. Always wait at least ten minutes before reheating the iOpener.

    • Insert a second opening pick alongside the first and slide the pick down along the edge of the iPad, releasing the adhesive as you go.

    • Throughout the rest of the procedure, if you encounter significant resistance while sliding the pick, stop and reheat the section you're working on. Applying too much pressure with the pick can crack the glass.

    • Continue moving the opening pick down the side of the display to release the adhesive.

    • If the opening pick gets stuck in the adhesive, "roll" the pick along the side of the iPad, continuing to release the adhesive.

  7. iPad mini 4 Wi-Fi Home Button Assembly Replacement: passo 7, immagine 1 di 2 iPad mini 4 Wi-Fi Home Button Assembly Replacement: passo 7, immagine 2 di 2
    • Take the first pick you inserted and slide it up toward the top corner of the iPad.

  8. iPad mini 4 Wi-Fi Home Button Assembly Replacement: passo 8, immagine 1 di 1
    • Reheat the iOpener and place it on the top edge of the iPad, over the front-facing camera.

    • Be careful not to overheat the iOpener during the repair procedure. Wait at least ten minutes before reheating the iOpener.

    • If you have a flexible iOpener, you can bend it to heat both the upper left corner and the upper edge at the same time.

    • Slide the opening pick around the top left corner of the iPad to separate the adhesive.

    • Slide the opening pick along the top edge of the iPad, stopping just before you reach the camera.

    • As you reach the front-facing camera, pull the pick out slightly and continue sliding it across the top edge.

    • Avoid sliding the opening pick over the front-facing camera, as you may smear adhesive onto the lens or damage the camera. The following steps will detail how to best avoid disturbing the front-facing camera.

    • Leave the opening pick in the iPad slightly past the front-facing camera.

    • Take a second pick and insert it to the left of the camera, where the first pick just was. Slide it back to the corner to completely cut any remaining adhesive.

    • Leave the second pick in place to prevent the corner adhesive from re-sealing as it cools.

  12. iPad mini 4 Wi-Fi Home Button Assembly Replacement: passo 12, immagine 1 di 2 iPad mini 4 Wi-Fi Home Button Assembly Replacement: passo 12, immagine 2 di 2
    • Insert the previous pick deeper into the iPad and slide it away from the camera toward the corner.

  13. iPad mini 4 Wi-Fi Home Button Assembly Replacement: passo 13, immagine 1 di 1
    • Leave the three picks in the corners of the iPad to prevent re-adhering of the front panel adhesive.

    • Reheat the iOpener and place it on the remaining long side of the iPad—along the volume and lock buttons.

    • Continue sliding the opening pick down the right edge of the iPad, reheating the edge using an iOpener if necessary.

    • Be careful not to slice too deep near the bottom right corner, or you risk damaging the display cable.

  16. iPad mini 4 Wi-Fi Home Button Assembly Replacement: passo 16, immagine 1 di 1
    • Leave the opening picks in place and reheat the iOpener.

    • Remember not to overheat the iOpener—no more than once every ten minutes.

    • Set the reheated iOpener on the home button end of the iPad and let it rest for a few minutes to soften the adhesive beneath the glass.

    • Rotate the new pick around the lower right corner of the device.

  18. iPad mini 4 Wi-Fi Home Button Assembly Replacement: passo 18, immagine 1 di 2 iPad mini 4 Wi-Fi Home Button Assembly Replacement: passo 18, immagine 2 di 2

    • When disconnecting any press connectors from the logic board, be sure to lift the connector straight up to avoid ripping the socket off the board.

    • Use the flat tip of a spudger to disconnect the battery connector from its socket on the logic board.

    • Bend the battery connector ribbon cable up slightly to prevent it from making contact and powering on the iPad.

  26. iPad mini 4 Wi-Fi Home Button Assembly Replacement, Display Assembly: passo 26, immagine 1 di 3 iPad mini 4 Wi-Fi Home Button Assembly Replacement, Display Assembly: passo 26, immagine 2 di 3 iPad mini 4 Wi-Fi Home Button Assembly Replacement, Display Assembly: passo 26, immagine 3 di 3
    • Use the pointed end of a spudger to disconnect the display data connector from its socket on the logic board.

    • Use the pointed end of a spudger to disconnect the digitizer cable connector from its socket on the logic board.

    • When reconnecting these, press down from one end of the connector to the other. If you press in the middle of the connector, you may bend it, causing damage or a poor connection.

  27. iPad mini 4 Wi-Fi Home Button Assembly Replacement: passo 27, immagine 1 di 1
    • Remove the display assembly.

    • To reinstall your display assembly, you will need to replace the display adhesive. Use our display adhesive application guide to reapply your display adhesive and reseal your device.

  31. iPad mini 4 Wi-Fi Home Button Assembly Replacement: passo 31, immagine 1 di 2 iPad mini 4 Wi-Fi Home Button Assembly Replacement: passo 31, immagine 2 di 2
    • Use an opening pick to continue separating the home button ribbon cable from the display assembly.

    • If you use metal tools to separate this cable, you may scratch the iPad glass, removing some paint.

  34. iPad mini 4 Wi-Fi Home Button Assembly Replacement: passo 34, immagine 1 di 2 iPad mini 4 Wi-Fi Home Button Assembly Replacement: passo 34, immagine 2 di 2
    • The home button is held in place by a thin, delicate, rubber gasket that is mildly adhered to the front panel.

    • Slowly push the home button up and out of the display assembly to separate the gasket from the front panel.

    • Be careful to not push the gasket past its tearing point. If the adhesive is adequately heated, it will separate from the front panel with some gentle pressure.

Is the piece of tape connecting the HB cable to the bracket important?

Perrin Aybara - Replica

Home Button still does not work after home button transfer and digitizer replacement.

MC EnderFromVN - Replica

there is a tiny black circle on the actual button underneath the kapton tape. if that isnt properly lined up it will not depress properly. also if the collar isnt perfect the home button will not sit correctly and popout. its a pretty crappy design by apple.

jsox79 -

I agree crappy design, i tried realigning button several times, best i got was “sort of works”

It took me several attempts - but I eventually got mine to work perfectly. I had put glue on the bracket - since there was glue on the old one - but that made the gap too wide, so it wasn’t seating the home button right. I also had a replacement that had a slightly bent plug for the touch - so it wasn’t seating properly and the touchscreen was not consistent. I eventually got it all seated (the connector and the home button). Then it worked like a charm. Thanks for the guide.
