Follow the steps in this guide to remove or replace a faulty or water-damaged logic board in an iPad mini 4 LTE.

Note that if you replace your logic board without a paired home button, you will lose Touch ID functionality.

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.

    • If your display glass is cracked, keep further breakage contained and prevent bodily harm during your repair by taping the glass.

    • Lay overlapping strips of clear packing tape over the iPad's display until the whole face is covered. For particularly bad breaks, you may need to lay down two layers.

    • This will keep glass shards contained and provide structural integrity when prying and lifting the display.

    • 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.

    • Protect your eyes! This procedure will cause small pieces of glass to fly directly toward your face. Do not attempt without safety glasses.

  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.

  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.

  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.

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

  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 the black bezel on the side of the display. Inserting the pick too far may damage the LCD.

    • Don't insert the opening pick any deeper than the black bezel on the side of the display. Inserting the pick too far may damage the LCD.

  7. Reheat and reapply the iOpener.
    • Reheat and reapply the iOpener.

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

    • Let it rest for a few minutes to reheat the left edge of the iPad.

  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.
