iPhone 12 Pro Max SIM Card Reader Replacement

• Insert a SIM card eject tool or a paperclip into the small hole in the SIM card tray, located on the volume button edge of the iPhone.
• Press firmly to eject the tray.

• Remove the SIM card tray from the iPhone.
• The SIM card will fall out of the tray easily.
• When reinserting the SIM card, make sure it's in the proper orientation inside the tray.
• A thin rubber gasket around the SIM tray provides water and dust protection. If this gasket is damaged or missing, replace the gasket or the entire SIM tray to protect your iPhone's internal components.

• Remove the two 6.7 mm-long pentalobe P2 screws at the bottom edge of the iPhone.

• Measure 3 mm from the tip and mark the opening pick with a permanent marker.

• 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.

• 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.

• 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.

• Use a hair dryer to heat along the bottom edge of the iPhone. The screen should feel slightly too hot to touch.
• For complete instructions on how to use a hair dryer, check out this guide.
• 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.
• 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.

• Use a hair dryer or a heat gun to heat the bottom edge of the iPhone until the screen is slightly too hot to touch.
• Never leave your hair dryer in one spot for an extended period of time.

• If you're using a single suction handle, apply it to the bottom edge of the phone, while avoiding the very edge of the glass.

• Step 11:
• Pull up on the suction cup with firm, constant pressure to create a slight gap between the screen and the frame.
• Insert an opening pick at a steep angle into the gap.
• 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.

• Step 12:
• Don't insert your opening pick deeper than 3 mm along the bottom edge.
• Slide your pick back and forth along the bottom edge to separate the adhesive.
• Leave your pick inserted in the bottom right corner to prevent the adhesive from re-sealing.

• 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.

• Slide the opening pick around the bottom right corner of the iPhone to separate its adhesive.
• Continue sliding up the right edge of the iPhone until you reach the top right corner.
• Don't insert your pick more than 3 mm, as you may damage internal components.
• Leave the pick in the top right corner before continuing.

• Use a hair dryer to heat the top edge of the iPhone until the screen is slightly too hot to touch.

• Slide the opening pick around the top right corner of the iPhone to separate the top adhesive.
• Do not insert your pick more than 3 mm, as you may damage the top sensors.
• Leave the pick in the top left corner before continuing.

Use a hair dryer to heat the left edge of the iPhone until the screen is slightly too hot to touch.

• Do not insert your pick deeper than 2 mm along the left edge to avoid damaging the two cables connecting the screen to the phone.
• Rotate your pick around the top left corner of the screen.
• Slide your pick to the bottom left corner of the screen to separate the adhesive.
• If you're having trouble separating the adhesive, reheat the left edge.

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.
Do not 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.

• Remove four 1.1 mm-long Y000 screws securing the battery and display connector cover.
• Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your iPhone.
• During reassembly, this is a good point to power on your iPhone and test all functions before you seal the display in place. Be sure to power your iPhone back down completely before you continue working.

• Use a spudger or a clean fingernail to pry the battery connector up from its socket on the logic board.
• 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.

• Use a spudger or a fingernail to disconnect the display cable connector.
• To re-attach press connectors like this one, carefully align and press down on one side until it clicks into place, then repeat on the other side. Do not press down on the middle. If the connector is misaligned, the pins can bend, causing permanent damage.

• Swing the cover up from the left until the small clip on the right unhooks.
• Remove the cover.
• During reassembly, insert the clip on the right edge into its slot first, then hinge the rest of the cover into place.

• Remove the display assembly.
• During reassembly, pause here if you wish to replace the waterproof adhesive around the edges of the display.

• Remove the two screws securing the SIM card reader.
• One 3.8 mm standoff screw
• Standoff screws are best removed using a standoff screwdriver or bit.
• In a pinch, a small flathead screwdriver will do the job-but use extra caution to ensure it doesn't slip and damage surrounding components.
• One 1.3 mm Phillips screw
