iPhone 7 Plus Logic Board Replacement

What you need

  1. iPhone 7 Plus Logic Board Replacement, Pentalobe Screws: step 1, image 1 of 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 3.4 mm pentalobe 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.

  2. iPhone 7 Plus Logic Board Replacement, Mark your opening picks: step 2, image 1 of 3 iPhone 7 Plus Logic Board Replacement, Mark your opening picks: step 2, image 2 of 3 iPhone 7 Plus Logic Board Replacement, Mark your opening picks: step 2, image 3 of 3
    • 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.

  3. iPhone 7 Plus Logic Board Replacement, Anti-Clamp instructions: step 3, image 1 of 3 iPhone 7 Plus Logic Board Replacement, Anti-Clamp instructions: step 3, image 2 of 3 iPhone 7 Plus Logic Board Replacement, Anti-Clamp instructions: step 3, image 3 of 3
    • 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 just above the home button—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.

  4. iPhone 7 Plus Logic Board Replacement: step 4, image 1 of 3 iPhone 7 Plus Logic Board Replacement: step 4, image 2 of 3 iPhone 7 Plus Logic Board Replacement: step 4, image 3 of 3
    • 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.

  5. iPhone 7 Plus Logic Board Replacement: step 5, image 1 of 2 iPhone 7 Plus Logic Board Replacement: step 5, image 2 of 2
    • 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.

    • 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.

  6. iPhone 7 Plus Logic Board Replacement, Heat the display: step 6, image 1 of 1
    • The next three steps show how to separate the screen using a suction cup.

    • Heating the lower edge of the iPhone will help soften the adhesive securing the display, making it easier to open.

    • Use a hairdryer or prepare an iOpener and apply it to the lower edge of the phone for about 90 seconds in order to soften up the adhesive underneath.

  7. iPhone 7 Plus Logic Board Replacement, Separate the display: step 7, image 1 of 2 iPhone 7 Plus Logic Board Replacement, Separate the display: step 7, image 2 of 2
    • Apply a suction cup to the lower half of the front panel, just above the home button.

    • Be sure the suction cup does not overlap with the home button, as this will prevent a seal from forming between the suction cup and front glass.

  8. iPhone 7 Plus Logic Board Replacement: step 8, image 1 of 3 iPhone 7 Plus Logic Board Replacement: step 8, image 2 of 3 iPhone 7 Plus Logic Board Replacement: step 8, image 3 of 3
    • 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 into the gap.

    • 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.

  9. iPhone 7 Plus Logic Board Replacement: step 9, image 1 of 3 iPhone 7 Plus Logic Board Replacement: step 9, image 2 of 3 iPhone 7 Plus Logic Board Replacement: step 9, image 3 of 3
    • Slide the opening pick up the left edge of the phone starting at the lower edge and moving towards the volume control buttons and silent switch, breaking up the adhesive holding the display in place.

    • Stop near the top left corner of the display.

    • Do not try to pry the top edge of the display away from the rear case, as it is held in place by plastic clips that may break.

  10. iPhone 7 Plus Logic Board Replacement, Screen information: step 10, image 1 of 1
    • There are delicate cables along the right edge of your iPhone. Don't insert your pick here, as you may damage the cables.

  11. iPhone 7 Plus Logic Board Replacement: step 11, image 1 of 3 iPhone 7 Plus Logic Board Replacement: step 11, image 2 of 3 iPhone 7 Plus Logic Board Replacement: step 11, image 3 of 3
    • Re-insert your tool at the lower right corner of the iPhone, and slide it around the corner and up the right side of the phone to separate the adhesive.

    • Don't insert your pick more than 3 mm, as you may damage the display cables.

  12. iPhone 7 Plus Logic Board Replacement: step 12, image 1 of 2 iPhone 7 Plus Logic Board Replacement: step 12, image 2 of 2
    • Gently pull up on the suction cup to lift up the bottom edge of the display.

    • Do not raise the display more than 15º or you'll risk straining or tearing the ribbon cables connecting the display.

    • Pull on the small nub on the suction cup to remove it from the front panel.

  13. iPhone 7 Plus Logic Board Replacement: step 13, image 1 of 3 iPhone 7 Plus Logic Board Replacement: step 13, image 2 of 3 iPhone 7 Plus Logic Board Replacement: step 13, image 3 of 3
    • Slide an opening pick underneath the display around the top left corner and along the top edge of the phone to loosen the last of the adhesive.

  14. iPhone 7 Plus Logic Board Replacement: step 14, image 1 of 2 iPhone 7 Plus Logic Board Replacement: step 14, image 2 of 2
    • Slide the display assembly slightly down (away from the top edge of the phone) to disengage the clips holding it to the rear case.

  15. iPhone 7 Plus Logic Board Replacement: step 15, image 1 of 3 iPhone 7 Plus Logic Board Replacement: step 15, image 2 of 3 iPhone 7 Plus Logic Board Replacement: step 15, image 3 of 3
    • Open the iPhone by swinging the display up from the left side, like the back 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.

  16. iPhone 7 Plus Logic Board Replacement, Battery Disconnection: step 16, image 1 of 1
    • Remove the following four tri-point Y000 screws securing the lower display cable bracket to the logic board:

    • Three 1.2 mm screws

    • One 2.6 mm screw

  17. iPhone 7 Plus Logic Board Replacement: step 17, image 1 of 2 iPhone 7 Plus Logic Board Replacement: step 17, image 2 of 2

    • Use the point of a spudger to lift the battery connector out of its socket on the logic board.

    • Bend the connector cable up slightly to prevent it from making contact with the socket and providing power to the phone.

  19. iPhone 7 Plus Logic Board Replacement, Display Assembly: step 19, image 1 of 3 iPhone 7 Plus Logic Board Replacement, Display Assembly: step 19, image 2 of 3 iPhone 7 Plus Logic Board Replacement, Display Assembly: step 19, image 3 of 3
    • Make sure the battery is disconnected before you disconnect or reconnect the cables in this step.

    • Use the flat end of a spudger or a fingernail to disconnect the two lower display connectors by prying them straight up from their sockets on the logic board.

    • To re-attach press connectors, press down on one end until it clicks into place, then repeat on the other end. Do not press down on the middle. If the connector is even slightly misaligned, the connector can bend, causing permanent damage.

    • If you have a blank screen, white lines on the display, or partial or complete lack of touch response after reassembling your phone, try disconnecting and carefully reconnecting both of these cables and make sure they are fully seated.
