简介

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.

  1. We recommend that you clean your microwave before proceeding, as any nasty gunk on the bottom may end up stuck to the iOpener. Place the iOpener in the center of the microwave.

    • We recommend that you clean your microwave before proceeding, as any nasty gunk on the bottom may end up stuck to the iOpener.

    • Place the iOpener in the center of the microwave.

    • For carousel microwaves: Make sure the plate spins freely. If your iOpener gets stuck, it may overheat and burn.

  2. Heat the iOpener for thirty seconds.

    • Heat the iOpener for thirty seconds.

    • Throughout the repair procedure, as the iOpener cools, reheat it in the microwave for an additional thirty seconds at a time.

    • Be careful not to overheat the iOpener during the repair. Overheating may cause the iOpener to burst.

    • Never touch the iOpener if it appears swollen.

    • If the iOpener is still too hot in the middle to touch, continue using it while waiting for it to cool down some more before reheating. A properly heated iOpener should stay warm for up to 10 minutes.

    编辑

  3. Remove the iOpener from the microwave, holding it by one of the two flat ends to avoid the hot center.

    • Remove the iOpener from the microwave, holding it by one of the two flat ends to avoid the hot center.

    • The iOpener will be very hot, so be careful when handling it. Use an oven mitt if necessary.

    编辑

  4. Handling it by the tabs on either side, place the heated iOpener on the side of the iPad to the left of the home button assembly.

    • Handling it by the tabs on either side, place the heated iOpener on the side of the iPad to the left of the home button assembly.

    • Let the iOpener sit for about five minutes to soften the adhesive beneath the glass.

    编辑

  5. Carefully place 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 to slightly separate the front panel assembly from from the rear case.

    • 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 to slightly separate the front panel assembly from from the rear case.

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

    编辑

  6. While holding the glass up with the suction cup, slide 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.

  8. Place 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 to sliding picks beneath the glass, stop and reheat the section you're working on. Applying too much pressure with the pick can crack the glass.

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

Perrin Aybara - 回复

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

MC EnderFromVN - 回复

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.
