    • The adhesive strips at the top of the battery are less likely to rip if you pull them horizontally in a straight line and not upwards or in any other direction.

    • Use a set of tweezers to unfold the black tab enough to grab with your fingers.

    • Pull the first adhesive strip in a slow and constant movement.

      • Jerking or slackening your grip can cause the adhesive to bunch up and rip.

    • Loosen the end of the other adhesive strip with a tweezer and pull it out. If needed use the iOpener again to soften the glue a little.

    • Use a spudger to slide under the battery.

      • If you managed to pull out the adhesive strips you can easily lift out the battery. Otherwise use the iOpener once more to soften any adhesive leftovers. There are no cables under the battery that can be harmed.

    • Remove the battery.

    • When reassembling your phone replace old adhesive with double-sided tape or pre-cut adhesive strips.

    • Use a spudger to lift and remove the motherboard assembly, being mindful of the cameras.

    • On the back of the motherboard are thermal pads (pink rubber-like gobs) for heat dissipation. If theses thermal pads broke, are too dried out or stick to the old display assembly, you need to apply new thermal pads on the new display assembly or the motherboard.

    • When reassembling your phone replace old adhesive with double-sided tape or pre-cut adhesive strips.
