If inserted too far, an opening pick can damage your device. Follow this step to mark your pick and prevent damage.
Measure 3 mm from the tip and mark the opening pick with a permanent marker.
You can also mark the other corners of the pick with different measurements.
Alternatively, tape a coin to a pick 3 mm from the tip.

The next four steps demonstrate the Anti-Clamp, a tool we designed to make the opening procedure easier. If you aren't using the Anti-Clamp, skip down four steps for an alternate method.
For complete instructions on how to use the Anti-Clamp, check out this guide.
The Anti-Clamp applies suction to both the screen and the back glass. To open only the back glass, you need to secure the screen with tape. You can also check out the full instructions on how to use this tape.
Cut two strips of tape, apply them along the long edges of the phone, and fold them over the screen to secure it.

Pull the Anti-Clamp's blue handle backward to unlock the arms.
With the back glass facing up, slide the arms over the right edge of your phone, with one suction cup on the back glass and the other on the screen. Center the suction cups near the bottom edge.
Support your phone so it rests level while between the Anti-Clamp's arms—a small box works well.
Squeeze the cups together to create suction.
If you find that the surface of your phone is too slippery for the Anti-Clamp to hold onto, use tape to create a grippier surface.

Pull the blue handle forward to lock the arms.
Turn the handle one full turn (360 degrees) or until the cups start to stretch.
As the cups stretch, make sure they stay vertically aligned with each other. If they keep slipping, remove the Anti-Clamp and apply tape for the cups to stick to.
If you don't have tape, you may warm up the suction cups to help them stick.

Use a hair dryer or heat gun to heat the bottom edge of the back glass until it's hot to the touch.
Be careful not to heat the phone hotter than this—the battery is susceptible to heat damage.
Wait up to a minute for the adhesive to separate and a gap to form between the back glass and the frame.
If a gap doesn't appear after one minute, apply more heat and rotate the handle a quarter turn. Let the Anti-Clamp and time do the work for you.
Insert an opening pick into the gap.
Remove the Anti-Clamp using the pull tabs on the suction cups.
Skip the next two steps.

As you slice the adhesive securing the back glass in the next steps, be careful of the following areas:
There's a delicate cable connecting the back glass to the phone, right next to the volume down button. Don't insert your pick here to avoid slicing the cable.
There are multiple spring contacts around the perimeter of the phone. Be extra careful not to insert your pick deeper than suggested in each step to avoid bending these contacts.
