How to fix iTunes error 9 in an Apple iPhone 6s

Introduzione

Use this guide to fix a faulty logic board in your iPhone 6s. Repairing a logic board may require micro-soldering.

A faulty logic board can also be replaced using the steps in this guide. 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.

See this iPhone 6s iTunes Hardware Restoration guide to help fix your phone’s logic board.

Fix iPhone 6s iTunes Error

  1. How to fix iTunes error 9 in an Apple iPhone 6s, Pentalobe Screws: passo 1, immagine 1 di 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, on either side of the Lightning connector.

    • If you don't have an Anti-Clamp, follow the next three steps to use a suction handle.

    • 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. How to fix iTunes error 9 in an Apple iPhone 6s: passo 3, immagine 1 di 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.

    • 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.

    • 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.

    • 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.

Does anybody have more detailed instructions? Maybe in written form? I don’t know where to find the board and which tools I need. And did I understand right - he’s boiling the board, so he’s heating it up?
