Introduction

Ce tutoriel vous montrera comment remplacer l'antenne Wi-Fi qui se trouve au-dessus des connecteurs de l'écran, près du haut du téléphone.

  1. Avant de commencer, déchargez votre batterie iPhone en dessous de 25%. Une batterie lithium-ion chargée peut prendre feu et / ou exploser si elle est perforée accidentellement.
    • Avant de commencer, déchargez votre batterie iPhone en dessous de 25%. Une batterie lithium-ion chargée peut prendre feu et / ou exploser si elle est perforée accidentellement.

    • Éteignez votre iPhone avant de commencer le démontage.

    • Sur le boîtier arrière de votre iPhone 4, il y a ou bien deux vis cruciformes #000 ou bien des vis Apple 5 points Pentalobe (deuxième image). Vérifiez de quelles vis il s'agit et assurez-vous d'avoir le tournevis qu'il vous faut pour les enlever.

    • Enlevez les deux vis de 3,6 mm (Pentalobe ou cruciforme #000) près du connecteur de dock.

      • Assurez-vous que le tournevis a une bonne prise lorsque vous retirez les vis Pentalobe, car elles dérapent très facilement.

    • Lors du remontage, nous vous conseillons de remplacer les vis 5 points par des vis cruciformes équivalentes. Notre Liberation Kit vous fournit les outils et les vis nécessaires pour remplacer les vis Pentalobe par des vis cruciformes.

    Caution: New phones may contain T1 screw heads instead of Phillips.

    any news on those screwdrivers? where can we buy them?

    using something like the 18-compartment tray will GREATLY help with this one; there are over a dozen groups of parts. For re-assembly having a digital calipers to measure the 2.4 vs the 2.6mm screws also helps greatly.

    My method for hardware management during delicate phone surgery is to take and print out on 8.5"x11' paper, one or more pictures of the open phone in various stages of disassembly, and then tape the screws to the appropriate spots on the pictures. Also write numbers on the pictures next the screws to indicate the order in which you removed them.

    I use a plastic egg tray, I drop all the screws and small parts (like the camera) for each step into the same egg indentation. You can see that the screws are different lengths, so I don't put one screw into it's own spot. I used 5 egg indentations to replace my screen.

    I did a successful surgery on my iPhone, be warned this is not for the faint of heart!

    I've done iPod screen replacements, battery replacements, this is by far much more difficult and intricate.

    Great write up! Thanks a million.

    I've changed some iPod screens as well and that has been the least pleasant experience so far. Glue and the main connector that has to be unwrapped and connected from the rear where you have no feel or control where it belongs.

    iPhone repair is complex, but doable and has very few "traps".

    Couldn't even get both screws out of the bottom of the case. One was easy and other refuses to budge. Screws so small I can't see if it is turning or screw driver is properly seated. Sad I too have done screen replacements on other phones. Don't know any secrets to get the screw out

    I also have a problem with seeing what is happening with some of those tiny little screws and parts. For other projects that I do, I use an Opti-Visor. It slips over your head and provides 10x magnification. ( You can find them on Amazon).

    Yeah, it adds cost to the project and you would have to wait for delivery, but it sure makes a world of difference in seeing what you are working with / on.

    On an early iPhone 4 I found that the #000 Phillips bit included in the 54 Bit Driver Kit didn't actually fit the screws. However the JIS #000 also in the kit did fit quite well. This is due to the JIS bits "thinner" design to prevent camming out of the slot. Otherwise everything went well. Looking forward to replacing the battery in my other phone that has the pentalobe screws. Glad I got the 54 Bit kit!

    Use a vacuum duster and a sharp tool to pry out the dust, this can increase the volume insanely!

    At the very last second before insertion, the second new screw for the bottom popped out of my pliers! I dont' want to use the old ones, but I don't want to leave it with one screw. Can I get a replacement screw?

    Otherwise it went together fine, and I figured out for myselkf that the contact needs to be bent,,,

    What does the park that is gold and next to the 4.8mm screw for the antenna? Looks like I am missing that part and almost positive that is why I can't pick up or connect to any wifi signals. I have the screw and the antenna from another phone that is working and tried it on the broken phone and still doesn't work. Only thing different is that gold metal piece to the left of that 4.8 mm screw. Can I buy that part? how do I attach it?

    For organisation of the parts and for a much easier process of rebuilding i use a big magnetic flat surface with a grid drawn on it. Then I use a dry erase marker to make any notes I need and to number the parts in order as i disassemble . Believe me it saves a lot of time and hassle especially if you drop one of those tiny screws good luck finding it but when your working over the magnet and drop a screw its going to be right where it fell. At first I tried the piece of paper to keep organised but all it takes is one small slip and you move the paper too quick and your left with a jumbled bunch of screws and parts and a painstaking task of putting it all back correctly, aka a big waist of time and effort.

    I found it very useful to use a magnet sheet when doing these repairs. I use electrical tape or a sharpie to make a grid, and place each micro screw in a separate box on the grid.

    I work directly over the magnet sheet, so that if something drops I have a better chance at not losing it.

    If you do lose a screw, go over the work area with a fridge magnet. It will pick it up if it hasn’t popped too far away.

  2. Faites glisser la vitre arrière vers le bord supérieur de l'iPhone.
    • Faites glisser la vitre arrière vers le bord supérieur de l'iPhone.

    the back won't budge! I cant get it off! what do i do?

    Debbie - Réponse

    Use a suction cup to pull the back screen gently.

    If the back doesn't slide in properly upon reassembly, you didn't insert the motherboard properly. Remove it and try it again, DO NOT try to force it down!

    • Attrapez la vitre arrière et retirez-la de l'iPhone. Vous pouvez également utiliser une petite ventouse.

    • Veillez à ne pas endommager les clips en plastique attachés à la vitre arrière.

    • Si vous installez une nouvelle vitre arrière, assurez-vous d'enlever l'autocollant de protection en plastique de l'intérieur de la lentille de la caméra et l'autocollant de la large zone noire près de la lentille.

    Remove the single 2.5 mm Phillips screw securing the battery connector to the logic board- for me this Phillips screw won't budge from its place have tried all the phillips combinations 000, 00, 0, 1 and the straight /slotted 1.5 mm but nothing. can some help me please purchased a replacement battery for my iPhone 4 but not able to do it just because of this screw.

    Naved Zaidi - Réponse

    If the screw head is not buggered, press the tip of a hot soldering iron to the screw for a second or two. Don't get it too hot, or you'll damage something.

    splaye -

    don't use hot soldering iron . the female outlet the battery plugs into is very fragile . for no extra money you can buy a battery that has magnetic tools specifically to pick this screw out . if worse comes to worse be certain the screw will come no looser then use tweezers and pick it out . the #1 fear with this technique is DO NOT DROP THE SCREW . I have done this and crawling on my hands and knees till I find it was depressing

    I have tried everything to remove the screw securing the battery connector to the logic board and nothing. Any help?

    • Retirez les cinq vis suivantes fixant l'antenne Wi-Fi à la carte mère :

      • Une vis cruciforme de 2,3 mm

      • Deux vis cruciformes de 1,6 mm

      • Une vis cruciforme de 1,4 mm

      • Une vis cruciforme de 4,8 mm

    • Lors du remontage, commencez par revisser la vis cruciforme de 4,8 mm, puis celle de 2,3 mm. Ceci permet de ne pas les confondre et d'éviter de rendre l'écran LCD et le numériseur inutilisables.

    • Assurez-vous également de remettre correctement la vis cruciforme de 4,8 mm pendant le remontage. C'est la mise à terre de l'antenne Wi-Fi et risque d'être la coupable, si vous avez une mauvaise connexion Wi-Fi après le remontage.

    As the hole for the EMI shield/antenna was slightly small, I had to hold the screw with tweezers whilst spinning it with the screwdriver so it would "drill" down through and connect

    Out of all the repair youtube videos that supposedly people seem to know how to fix the I phone 4. Through my own error I found out the large screw at the middle top (blue) should not be removed just loosened there is a small ground clip that attaches to the threads on the screw and touches the back of the board to provide WIFI ! I found this after not receiving WIFI I striped out the main board found the clip, placed it on the top side so the small clip touched the gold dot on the top right side of the board(WRONG) the phone shorted out the power management chip so my phone wont charge or recognise the data cord! kaput !! a simple mistake but hope it gives you an advantage that's why the WIFI plate is designed to allow removal without completely removing the screw!

    • Utilisez un outil d'ouverture pour iPod pour soulever légèrement le bord supérieur de l'antenne Wi-Fi de la carte mère.

    • Utilisez la pointe d'un spudger pour retirer les clips de fixation de l'antenne Wi-Fi du châssis intérieur.

    • Retirez l'antenne Wi-Fi de l'iPhone. Assurez-vous de ne pas perdre les clips métalliques sur le dessus du cache, à l'emplacement de la vis de 4,8 mm. C'est la raison principale de performances Wi-Fi anormales après le remontage.

    • Avant le remontage, assurez-vous de nettoyer tous les points de contact métal-métal sur le cache du connecteur avec un dégraisseur comme Windex. Le sébum sur vos doigts peut causer des problèmes d'interférence avec les connecteurs sans fil. Ne nettoyez pas les connecteurs eux-mêmes avec le produit.

The wifi antenna has a small clip connecting the black antenna to the logic board.

Its very small and apparently easy to loose as i never even saw mine. If you loose it you will not have a good wifi signal untill its replaced.

trae - Réponse

It's doesn't work i'm sorry

mariocrocop - Réponse

I purchased an iPhone 4 GSM new/sealed from an Apple Store in July 2010

and never needed to connect to multiple Wi-Fi networks until recently.

When I would go from a known Wi-Fi connection to another one,

I would need to go into Settings to reconnect each time.

I figured that I needed to replace the Wi-Fi antenna.

When I took off the back panel, I discovered that the 4.8mm Phillips screw

that grounds the Wi-Fi antenna is not present. So, you might want to first

check that the screw is there and properly secured.

Still doesn't work ... one or two bar near a-port express / everything is in order - just one screw miss / yellow one [1.4 mm Phillips] - U think that's the reason ?? Please, help :(

Ifixit no longer sells the WiFi antennas but I found a perfectly good one on Ebay

panchocole - Réponse

Um... That isn't the WiFi antenna. The wireless antenna is under the logic board. It runs along the inside edge and looks like the 3g antenna. It connects at the top and bottom but can still function with one end connected. Perhaps the bottom cap isn't seated properly? It would explain the symptoms... Also I wouldn't worry about the screws so much. Its such a snug fit that once the flex cables are reattached and the back cover is on nothing can move anyway, plus it will make it easier for you next time you need to have a look or if it gets wet and you need to pull the battery in a hurry. This guide should be taken down. The world is confusing enough... Just saying;)

You sir, are correct. This item is a shield for the components underneath of it.
