    • The Anti-Clamp needs smooth, even surfaces for its suction cups to adhere to.

    • If your device has cracked glass or a slippery surface, follow this guide to apply the included tape pad.

    • Packing tape also works to cover a cracked display.

    • If your back glass is badly shattered, the tape might damage it further. Refer to your specific guide to use a suction handle instead.

    • If your device can be opened from both its screen and back cover, follow this guide to apply the included tape strips.

    • Center the suction cups over a smooth area of the device near the starting edge.

    • Avoid buttons, gaps, seams, and speakers, as they will prevent a good hold.

    • Improper alignment may cause the cups to separate prematurely. Pull the cups off the device using their pull tabs and re-center them.

    • Most adhesives separate under constant tension rather than more force. Take your time during this process to avoid breaking the suction cups free or violently opening your device.

    • Twist the handle clockwise one full rotation (360 degrees) or until the cups begin to stretch.

  9. How to Use the Anti-Clamp, Heat your device: step 9, image 1 of 2 How to Use the Anti-Clamp, Heat your device: step 9, image 2 of 2
    • For smaller devices, thread a heated iOpener through the arms of the Anti-Clamp to heat your device.

    • For larger devices, or iPhone models 12 and newer, use a hair dryer or a heat gun to soften the adhesive along your starting edge.

    • iPhone models 12 and newer have a tougher adhesive that the iOpener is less effective at opening than a hair dryer or heat gun.

    • Be careful not to overheat your device. The edge should feel slightly too hot to touch.

    • Wait one minute to give the adhesive a chance to release and present a gap.

    • If the Anti-Clamp doesn't separate the adhesive after one minute, apply more heat and wait another minute. Be patient and let the Anti-Clamp do the work for you.

    • If, after several rounds of heating, the device doesn't show any signs of opening, twist the knob one quarter-turn.

    • Don't twist the knob more than three additional quarter-turns. Only use additional heat at this point. The more you twist the knob, the more likely the device is to suddenly pop open.

Very clear step-by-step guide. The next time I do a battery replacement I intend to use one of these.

Engaging the Opening Mode the first time takes a bit of a push, don't be afraid, keep pushing until you hear a click. Seems to be easier to engage after the first time.

Hi Ed,

Thanks for the helpful feedback! I've implemented your note into the guide step.

Looks like an answer to a problem that I don't have right now but I plan to purchase one of these before I do any more battery replacements.

I used mine to open a Samsung Galaxy Tab A7 tablet. Very frustrating, seemed like you needed three hands to put it in place (though later I found a better procedure). The OEM case glue was quite powerful (used a heating pad to get the tablet Very hot). The Anti-Clamp had difficulty holding to the back of the case and kept losing its grip. I didn't try the packing tape trick, just now noticed it. I mainly used the top suction cup just by itself.

The replacement battery had a very long battery cable and didn't lay flat, which caused a bright spot on the display where the cable "kink" was. So time to remove the case again. This time I stuck each suction cup individually, screen side first, the case - firmly pressing each cup flat after placement. No need to "fight" the Anti-Clamp to get it in place, plus I think I got a better hold with the cups. The B-7000 glue I used was much easier to break loose than the OEM case glue.

To loosen the suction cups I slid an opening pick under the edge of the cup.
