    • 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.

  2. iPad mini 4 LTE Logic Board Replacement, iOpener Heating: stap 2, afbeelding 1 van 2 iPad mini 4 LTE Logic Board Replacement, iOpener Heating: stap 2, afbeelding 2 van 2
    • 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.

  3. iPad mini 4 LTE Logic Board Replacement: stap 3, afbeelding 1 van 1
    • 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. Do not attempt to heat over 100˚C (212˚F).

    • 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.

  4. iPad mini 4 LTE Logic Board Replacement: stap 4, afbeelding 1 van 1
    • 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.

  5. iPad mini 4 LTE Logic Board Replacement, Alternate iOpener heating method: stap 5, afbeelding 1 van 2 iPad mini 4 LTE Logic Board Replacement, Alternate iOpener heating method: stap 5, afbeelding 2 van 2
    • If you don't have a microwave, follow this step to heat your iOpener in boiling water.

    • Fill a pot or pan with enough water to fully submerge an iOpener.

    • Heat the water to a boil. Turn off the heat.

    • Place an iOpener into the hot water for 2-3 minutes. Make sure the iOpener is fully submerged in the water.

    • Use tongs to extract the heated iOpener from the hot water.

    • Thoroughly dry the iOpener with a towel.

    • The iOpener will be very hot, so be careful to hold it only by the end tabs.

    • Your iOpener is ready for use! If you need to reheat the iOpener, heat the water to a boil, turn off the heat, and place the iOpener in the water for 2-3 minutes.

    • 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.

  8. iPad mini 4 LTE Logic Board Replacement: stap 8, afbeelding 1 van 2 iPad mini 4 LTE Logic Board Replacement: stap 8, afbeelding 2 van 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.

  9. iPad mini 4 LTE Logic Board Replacement: stap 9, afbeelding 1 van 1
    • 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.

  10. iPad mini 4 LTE Logic Board Replacement: stap 10, afbeelding 1 van 3 iPad mini 4 LTE Logic Board Replacement: stap 10, afbeelding 2 van 3 iPad mini 4 LTE Logic Board Replacement: stap 10, afbeelding 3 van 3
    • 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.

  11. iPad mini 4 LTE Logic Board Replacement: stap 11, afbeelding 1 van 3 iPad mini 4 LTE Logic Board Replacement: stap 11, afbeelding 2 van 3 iPad mini 4 LTE Logic Board Replacement: stap 11, afbeelding 3 van 3
    • 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.

  12. iPad mini 4 LTE Logic Board Replacement: stap 12, afbeelding 1 van 2 iPad mini 4 LTE Logic Board Replacement: stap 12, afbeelding 2 van 2

  13. iPad mini 4 LTE Logic Board Replacement: stap 13, afbeelding 1 van 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.

  14. iPad mini 4 LTE Logic Board Replacement: stap 14, afbeelding 1 van 3 iPad mini 4 LTE Logic Board Replacement: stap 14, afbeelding 2 van 3 iPad mini 4 LTE Logic Board Replacement: stap 14, afbeelding 3 van 3

    • 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.

  17. iPad mini 4 LTE Logic Board Replacement: stap 17, afbeelding 1 van 2 iPad mini 4 LTE Logic Board Replacement: stap 17, afbeelding 2 van 2
    • Insert the previous pick deeper into the iPad and slide it away from the camera toward the corner.

  18. iPad mini 4 LTE Logic Board Replacement: stap 18, afbeelding 1 van 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.

  19. iPad mini 4 LTE Logic Board Replacement: stap 19, afbeelding 1 van 3 iPad mini 4 LTE Logic Board Replacement: stap 19, afbeelding 2 van 3 iPad mini 4 LTE Logic Board Replacement: stap 19, afbeelding 3 van 3

  21. iPad mini 4 LTE Logic Board Replacement: stap 21, afbeelding 1 van 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.

Één opmerking

This guide needs amending urgently before more people destroy their LCD displays by cutting through the tape holding the backlight to the LCD glass, or pushing a pick or other tool between the LCD glass and touchscreen glass.

The guide states:

Don't insert the opening pick any deeper than the black bezel on the side of the display.

This is WRONG and will destroy your display. The black bezel is 5mm wide, this is beyond the 1mm wide adhesive and into the LCD display and backlight assembly. Do not insert anything more than 2mm down the sides of the display.

Any further than 2mm and, like me, you will be looking at a very expensive LCD display replacement.

Thanks IFIXIT.COM for publishing an incorrect guide that has destroyed my display.
