Use this guide to replace unresponsive volume control buttons in an iPad mini 4 LTE.

This guide will teach you how to remove the volume control assembly which includes: the ribbon cable with the volume up and volume down switches on it, microphone, and volume control bracket. The guide does not detail the replacement of the exterior button covers.

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.

    • 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.

    • 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.

    • 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 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.

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

  16. iPad mini 4 LTE Volume Control Buttons Replacement: 17 단계, 이미지 1/1
    • 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.
