Introdução

Follow the steps in this guide to replace the logic board in an iPhone 6s.

It's important to note that each iPhone's logic board and Touch ID fingerprint sensor are paired at the factory, so replacing the logic board will disable Touch ID unless you also install a replacement home button that has been properly paired to your new logic board.

You can also use this guide for reference to replace the logic board EMI shield stickers.

  1. iPhone 6s Logic Board Replacement, Pentalobe Screws: step 1, image 1 of 1
    • Before disassembling your iPhone, discharge the 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 P2 Pentalobe screws on the bottom edge of the iPhone, next to the Lightning connector.

  2. iPhone 6s Logic Board Replacement, Opening Procedure: step 2, image 1 of 1
    • Optionally, apply mild heat to the lower edge of the iPhone using an iOpener or hair dryer for about a minute.

    • Heat softens the adhesive securing the display, making it easier to open.

  3. iPhone 6s Logic Board Replacement: step 3, image 1 of 1
    • Opening the display on the 6s separates a thin strip of adhesive around the perimeter of the display. If you prefer to replace the adhesive, have a set of new adhesive strips ready before you continue. It's possible to complete the repair without replacing the adhesive, and you probably won't notice any difference in functionality.

    • Apply a suction cup to the lower left corner of the display assembly.

    • Take care not to place the suction cup over the home button.

    • 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.

  4. iPhone 6s Logic Board Replacement: step 4, image 1 of 2 iPhone 6s Logic Board Replacement: step 4, image 2 of 2
    • Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case.

    • Take your time and apply firm, constant force. The display assembly is a much tighter fit than most devices and is held down with adhesive.

    • Pulling too hard may damage the display assembly. Apply just enough pressure to create a small gap between the display assembly and the rear case.

    • If you have any trouble, heat the front of the iPhone using an iOpener, hair dryer, or heat gun until it's slightly too hot to touch. This will help soften the adhesive securing the edges of the display.

  5. iPhone 6s Logic Board Replacement: step 5, image 1 of 2 iPhone 6s Logic Board Replacement: step 5, image 2 of 2
    • There is a notch on the underside of the display, just above the headphone jack. This is the safest place to begin prying the phone open.

    • Place the flat edge of a spudger into the gap between the screen and rear case, directly above the headphone jack.

  6. iPhone 6s Logic Board Replacement: step 6, image 1 of 2 iPhone 6s Logic Board Replacement: step 6, image 2 of 2
    • Twist the spudger to widen the gap between the front panel assembly and the rest of the phone.

  7. iPhone 6s Logic Board Replacement: step 7, image 1 of 2 iPhone 6s Logic Board Replacement: step 7, image 2 of 2
    • Insert the flat end of the spudger on the left side of the phone, between the display assembly and rear case.

    • Slide the spudger up the side of the phone to separate the adhesive and pop the clips free.

  8. iPhone 6s Logic Board Replacement: step 8, image 1 of 2 iPhone 6s Logic Board Replacement: step 8, image 2 of 2
    • Remove the spudger and reinsert it on the bottom edge, where you pried the phone open.

    • Slide the spudger to the right, along the bottom edge of the phone.

  9. iPhone 6s Logic Board Replacement: step 9, image 1 of 2 iPhone 6s Logic Board Replacement: step 9, image 2 of 2
    • Slide the spudger up the right side to continue separating the adhesive and popping the display clips free from the iPhone.

  10. iPhone 6s Logic Board Replacement: step 10, image 1 of 2 iPhone 6s Logic Board Replacement: step 10, image 2 of 2
    • Use the suction cup to open the display, breaking the last of the adhesive.

    • Don't open the display more than 90º, as it is still connected at the top by three cables that may break if stretched.

  11. iPhone 6s Logic Board Replacement: step 11, image 1 of 2 iPhone 6s Logic Board Replacement: step 11, image 2 of 2
    • Pull up on the nub on the top side of the suction cup to remove it from the front panel.

    • Gently grasp the display assembly and lift it up to open the phone, using the clips at the top of the front panel as a hinge.

    • Open the display to about a 90º angle, and lean it against something to keep it propped up while you're working on the phone.

    • Add a rubber band to keep the display securely in place while you work. This prevents undue strain on the display cables.

    • In a pinch, you can use an unopened canned beverage to hold the display.

    • Remove two Phillips screws securing the battery connector bracket, of the following lengths:

    • One 2.9 mm screw

    • One 2.2 mm screw

    • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your iPhone.

  13. iPhone 6s Logic Board Replacement: step 14, image 1 of 2 iPhone 6s Logic Board Replacement: step 14, image 2 of 2
    • Remove the battery connector bracket from the iPhone.

    • Use the point of a spudger to disconnect the battery connector by prying it straight up from the logic board.

  15. iPhone 6s Logic Board Replacement: step 16, image 1 of 2 iPhone 6s Logic Board Replacement: step 16, image 2 of 2

  19. iPhone 6s Logic Board Replacement: step 20, image 1 of 2 iPhone 6s Logic Board Replacement: step 20, image 2 of 2
    • Disconnect the digitizer cable by prying it straight up from its socket on the logic board.

    • When reconnecting the digitizer cable, do not press the center of the connector. Press one end of the connector, then press the opposite end. Pressing in the center of the connector can bend the component and cause digitizer damage.

  20. iPhone 6s Logic Board Replacement: step 21, image 1 of 2 iPhone 6s Logic Board Replacement: step 21, image 2 of 2

So all the logic boards come with the components installs? Like the High band PAD, power amplifier avago, power amplifier Skyworks, power amplifier TriQuint, LTE modem Qualcomm, and lastly the Apps processor Apple SoC stacked on Elpida RAM. Here I thought you had to buy them.

I'm also assuming that some don't. I would like to know that alternative.

Does the logic board have the SSD on them or they else where in the iPhone?

tazzy - Responder

Yup! The SSD is a flash memory chip hidden underneath an EMI shield on the logic board. You can see it in our teardown.

Evan Noronha -

Um, no, actually the NAND/ssd/flash/storage chip is the big Toshiba one in the middle, it’s the one next to the line of capacitors, and is not under the shields. there are shields on either side of it. Look at the teardown page you linked to yourself and you will confirm what I’ve said.

Sam the Techman -

great guide worked perfectly, had some minor water damaged internals with a completely good logic board, replaced it in a 16g pos basically have a brand new 128g 6s
