If your iPad's screen is badly cracked, wear skin and eye protection. Cover the screen with a smooth layer of clear packing tape to contain glass shards and help the suction cup adhere. Alternatively, use a strong piece of tape (such as duct tape) and fold it into a handle.

Place a suction cup next to the iPad's home button and press down to create a seal.

To get the most leverage, place the suction cup as close to the edge as possible without going past the edge of the display.

If you want to use the Anti-Clamp, a tool we designed to make the opening procedure easier, follow this guide.

Firmly pull up on the suction cup to create a small gap between the front panel and the rear case.

Don't pull too hard, or you may shatter the glass. If necessary, apply more heat to further soften the adhesive.

Once you've opened a sufficient gap, insert an opening pick into the gap.
