Introduzione

Follow this guide to replace the Wi-Fi diversity antenna and flex cable in your iPhone 8. This may help resolve connectivity issues.

  1. Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.
    • 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 3.5 mm pentalobe screws on 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. Heating the lower edge of the iPhone will help soften the adhesive securing the display, making it easier to open.
    • 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.

  3. 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.
    • 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.

    • 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. Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case. Insert an opening pick into the gap. The watertight adhesive holding the display 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.

    The screen on my phone was so broken, a suction cup did not work, so I softened the adhesive with a blow dryer and used a Jimmy to carefully pry open the phone from the bottom just enough to slip a pick in.

    Just completed a smashed screen replacement, this is probably the most time consuming part. Used packing tape to cover the screen to help create a suction surface (had to replace it a couple times because it pulls away after a purple good pulls ) Used consistent heat for about 5 minutes, then stuck a pick in the tiniest opening… and pry pry pry!

  5. 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.

  6. 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 the pick very far, or you may damage the display cables along this side of the iPhone. Insert it only a few millimeters, or about the width of the display bezel.

  10. 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.

    • Remove four Phillips screws securing the lower display cable bracket to the logic board, of the following lengths:

    • Two 1.3 mm screws

    • Two 2.8 mm screws

    • Throughout this guide, keep careful track of your screws so that each one goes back where it came from during reassembly. Installing a screw in the wrong place can cause permanent damage.

    • Remove the bracket.

    Make sure you pry the battery connector off from the right hand side as shown in the picture. Theres a delicate component on the logicboard near the battery connector called a Mosfet which is linked to the battery charging software. If you knock it off accidently you’ll loose battery charging and the phone will boot loop and youll need to have it re-soldered back on.

  12. Use the point of a spudger to pry the lower display connector out of its socket. To re-attach press connectors like this one, 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 even slightly misaligned, the connector can bend, causing permanent damage.

    If you are replacing the adhesive liner, the remaining release liner strips will interfere with the two outer screws. I had to cut a working section out of the liner at each location and move it aside with the spudger.

    This part is throwing me for a loop. Having difficulty finding the read head for these screws. Is it the same size as the two small 1.3mm screws in step 12?

  16. Remove the display assembly.

    Hi ifixit, if you find my method dangerous, please remove it.

    After Step 17, I skipped Step 18 to Step 28.

    At Step 29, I lifted up the four adhesive black pull-tabs to expose the white adhesive side. Next, I use hot air gun and blow on the back cover of the iphone for about a minute (maybe a hairdryer will work too) .

    Warning: Don't overheat the iPhone, or you may accidentally ignite the battery.

    I think the temperature was around 60 DegC.

    Extreme Caution: Do Not overheat. I use my hand to gauge the hotness. Careful not to burn yourself or the board.

    I was able to pull out all the white adhesive tapes easily as the adhesive soften.

    DO NOT TRY this method if you are a novice or inexperience! I am not responsible if you hurt yourself or damage your iphone!

    John - Replica

    Hey John! I’m glad the repair worked out for you!

    From our research, applying heat does soften the adhesive strips, but it also causes them to lose structural integrity and break more easily. That’s why we normally suggest using heat after the strips are already broken. Removing the Taptic Engine definitely takes a few extra steps, but we feel that it gives fixers the best chance of pulling out the adhesive strips intact.

    Arthur Shi -

  17. Remove the three screws securing the bracket next to the Taptic Engine:
    • Remove the three screws securing the bracket next to the Taptic Engine:

    • One 1.3 mm Y000 screw

    • One 2.7 mm Phillips screw

    • One 2.9 mm Phillips screw

    My phone had Phillips screws in all three places, so I did not need the Y000 screwdriver bit.

    Daryl Maunder - Replica

    I don’t see the point in steps 18-27 if we’re only changing the battery. I pulled out the sticky tape with taptic and all this other jazz still intact. Am I missing something? Reconnecting that taptic connection cost me 5 years off my life, needlessly.

    William Mitchell - Replica

    Hey William!

    We instruct people to remove the Taptic Engine in order to minimize the chance that the battery adhesive will tear when you try to pull it out. The steep angle you have to pull the adhesive with the Taptic Engine installed dramatically increases the chance that the adhesive will break under the battery.

    Arthur Shi -

    since the sticky tape will usually tear anyway and it is no big deal, I agree stop at this point and take the battery out. Too many things can go wrong removing more screws and connecting/disconnecting all the connectors. Go to video instructions at this point. Wish I did.

    Don’t worry if the socket lifts up a bit as you get it out. You’ll need to lift it up later (Step 25) so don’t push it back into place yet.

    Every instruction online (including your YouTube video) leaves the Taptic Engine in place. This added step did not help with battery replacement, and led to an hour of frustration trying to get the connector back in place.

Hello, The power of my iphone 8 plus other products is lower than the mains and wifi. When I dismantle the product in question, there is no change. Which product should change. The reason is that when I hold the top part of the phone the wifi and mains power is falling more and more.

kenany123456 - Replica

the two Phillips screws securing the bracket above the Taptic Engine won’t come out what do I do?

donnell wright - Replica

Hi Donnell,

Are the screws stripped or stuck? If they’re stripped, you can try some tips here.

Arthur Shi -

I’ve tested all networks on a phone without this antenna and it seems to work just fine.

What does the absence of this part actually entail?

Smeargle - Replica

The diversity antenna is basically an additional antenna which helps improve the Wi-Fi reliability and quality. Wireless functions should work without it, but this additional antenna can help in congested urban environments.

Arthur Shi -

Can someone please tell me what the connector is that the wifi diversity antenna plugs into by the taptic engine, as I have a phone in parts and it is missing that connector so my wifi diversity antenna has nothing to plug into. I am guessing the person I bought it off of lost it or broke it.

Doug - Replica

Hi Doug,

That connector connects to the lightning connector assembly, as seen here.
