Guide overview

Before you begin

In this repair guide, we show you how to replace the logic board on the iPhone 11 Recommended Tools: Pentalobe screwdriver, Phillips screwdriver, Y-Type screwdriver, Standoff screwdriver, suction cup, tweezers, spudger and heat gun because the display is glued on.

Step 1

  • 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 P2 screws at the bottom edge of the iPhone.
  • 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.
Step 2

  • 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

  • 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 step, 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

  • 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 top, and one on the bottom.
  • 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 forward 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.

  • Heat an iOpener and thread it through the arms of the Anti-Clamp.
  • You can also use a hair dryer, heat gun, or hot plate—but extreme heat can damage the display and/or internal battery, so proceed with care.
  • Fold the iOpener so it lays on the bottom edge of the iPhone.
  • Wait one minute to give the adhesive a chance to release and present an opening gap.
  • Insert an opening pick into the gap under the screen and the plastic bezel, not the screen itself.
  • 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.

  • Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case.
  • Insert an opening pick into the gap under the screen and the plastic bezel, not the screen itself.
  • The watertight adhesive holding the display 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.

  • Don't try to fully separate the display yet, as several fragile ribbon cables still connect it to the iPhone's logic board.
  • Prop the display up against something sturdy.
  • 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.
