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. Before disassembling your iPhone, discharge the battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.
    • 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. Optionally, apply mild heat to the lower edge of the iPhone using an iOpener or hair dryer for about a minute.
    • 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. 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.

  4. 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.

    • 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. 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.

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 - Antwoord

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
