• Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.
• Power off your iPhone before beginning disassembly.
• Remove the two 6.7 mm-long pentalobe screws at the bottom edge of the iPhone.

• 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.

Step 3

Tape over any cracks

• If your iPhone has a cracked screen, keep further breakage contained and prevent bodily harm during your repair by taping over the glass.
• Lay overlapping strips of clear packing tape over the iPhone's screen until the whole face is covered.
• Wear safety glasses to protect your eyes from any glass shaken free during the repair.
• If you can't get the suction cup to stick in the next few steps, fold a strong piece of tape (such as duct tape) into a handle and lift the screen with that instead.
• If all else fails, you can superglue the suction cup to the screen.

• To avoid damaging your screen in the next steps, note the following:
• There's a plastic bezel on the underside of the screen. Your opening pick will go underneath this bezel.
• There's a seam between the plastic bezel and the display panel. Don't insert your pick here or you'll damage the screen.
• Sometimes the display panel separates from the bezel before you even get a chance to insert a pick. This may be unavoidable depending on the condition of the adhesive. In this case, you’ll most likely need to replace your entire screen.

Step 5

Anti-Clamp instructions

• The next three 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 three steps for an alternate method.
• For complete instructions on how to use the Anti-Clamp, check out this guide.
• Pull the blue handle backwards to unlock the Anti-Clamp's arms.
• Slide the arms over either the left or right edge of your iPhone.
• Position the suction cups near the bottom edge of the iPhone—one on the front, and one on the back.
• Squeeze the cups together to apply suction to the desired area.
• If you find that the surface of your iPhone is too slippery for the Anti-Clamp to hold onto, you can use tape to create a grippier surface.

• Pull the blue handle forwards to lock the arms.
• Turn the handle clockwise 360 degrees or until the cups start to stretch.
• Make sure the suction cups remain aligned with each other. If they begin to slip out of alignment, loosen the suction cups slightly and realign the arms.

• Support your iPhone on something sturdy such as a hardcover book so it rests hands-free and parallel to the ground; this makes it easier to work with in the following steps.
• Use a hair dryer to heat along the bottom edge of the iPhone. The screen should feel slightly too hot to touch.
• Wait one minute to give the adhesive a chance to release and present an opening gap.
• Insert an opening pick under the screen's plastic bezel when the Anti-Clamp creates a large enough gap.
• Make sure the opening pick is placed properly between the plastic bezel and the frame to avoid damaging your screen.
• If the Anti-Clamp doesn't create a sufficient gap, apply more heat to the area and rotate the handle a quarter turn.
• Don't crank more than a quarter turn at a time, and wait one minute between turns. Let the Anti-Clamp and time do the work for you.
• Skip the next three steps.

Step 8

Heat the bottom half of the phone

• Opening the iPhone's display will compromise its waterproof seals. Have replacement seals ready before you proceed past this step, or take care to avoid liquid exposure if you reassemble your iPhone without replacing the seals.
• Heating the bottom half of the iPhone helps soften the adhesive securing the display, making it easier to open.
• Use a hair dryer or a heat gun to heat the bottom half of the iPhone until the screen is slightly too hot to touch.
• For best practices on using a hair dryer to soften adhesive, check out this guide. For warnings on heat gun use, check out this guide.
• To prevent screen damage, keep your heat source moving rather than focused on one spot.
• If you have trouble during the opening procedure, the adhesive most likely cooled down. Apply more heat to further soften the adhesive.

Step 9

Apply a suction handle

• If you're using a single suction handle, apply it to the bottom edge of the phone, as close to the edge as possible.
• If your display is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken screen.

Step 10

Lift the screen slightly

• Pull up on the suction cup with firm, constant pressure to create a slight gap between the screen and the metal frame.
• A plastic bezel is secured to the underside of the display, and needs to lift up with the display. Inserting a pick between the bezel and the display will damage the panel.
• Insert an opening pick into the gap under the screen and the plastic bezel, not the screen itself.
• Make sure to insert the opening pick under the thick plastic bezel to avoid damaging your screen. You should see a visual gap, and the pick shouldn't catch on anything. If you can't see the gap, you'll need to pull the screen up more.
• The watertight adhesive holding the screen in place is very strong; creating this initial gap takes a significant amount of force. If you're having a hard time opening a gap, apply more heat, and gently rock the screen up and down to weaken the adhesive until you create enough of a gap to insert your tool.

Separate the bottom edge adhesive

Step 12

Heat the right edge

• Use a hair dryer to heat the right edge of the iPhone (the edge with the power button) until the screen is slightly too hot to touch.

• Rotate your iPhone so the right edge faces you.
• Open the iPhone by swinging the display up from the right side, like the front cover of a book.
• Don't try to fully separate the display yet, as several fragile ribbon cables still connect it to the iPhone's logic board.
• Lean the display against something to keep it propped up while you're working on the phone.
• During reassembly, lay the display in position, align the clips along the top edge, and carefully press the top edge into place before snapping the rest of the display down. If it doesn't click easily into place, check the condition of the clips around the perimeter of the display and make sure they aren't bent.

• Try not to damage the black silicone seal surrounding this and other board connections. These seals provide extra protection against water and dust intrusion.
• Bend the connector slightly away from the logic board to prevent it from accidentally making contact with the socket and providing power to the phone during your repair.
