    • 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.

    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 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!

    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.

    case-yg - Réponse

    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.

    Just be careful when removing the battery with the plastic pull tab. On some units, they use so much glue that it's virtually impossible to take the battery.

    use the iPod opening tool to pry gently under the battery from the outer edge of the phone and work towards the plastic tab. the tab is not actually attached to the battery itself, but a plastic sheet between the battery and inner frame. the adhesive on the battery tends to be under the edge of the battery nearest the center of the phone.

    My battery was so firmly glued in, it took a long time to slowly pry it loose. Patience is the key to this process. I could see easily damaging the circuit board by using too much force. The plastic tab did not help at all.

    The ribbon cable attaching the new battery to the battery connector clip is longer than the original. I clicked the clip into the socket first and then was very careful to fold the excess while putting the battery back in so the ribbon cable didn't kink. One kink in this could sever the battery leads.

    My ribbon cable was also longer than the original. How did you get it to not kink while placing the batter back into the phone? That seems to be my only hang up at the moment

    cvbaseballsean22 -

    Piece of cake! The hardest part was being sure the outer pentalobe screws were actually turning and I wasn't stripping them. Battery was glued firmly in, so I loosened it from the outside instead of using the plastic pull-tab. I pre-bent the battery connector neck before putting it back in and had no problems with it fitting in. Getting the battery connector aligned with the antenna piece underneath was a bit fiddly. Got the case back on, put in the new screws, and powered the phone on without problem. Had 40% charge, all seems well. Yippee!

    chezbuttons - Réponse

    Do NOT use a spudger or similar type of prising tool to try lift up the battery. Instead, just warm up the whole area with a hot air gun or hair drier to soften the glue.

    The reason why I say don't use an implement to try lift the battery is because far too many times I've seen punctured & bent batteries come in to this workshop that have to be thrown out for safety reasons. It only takes a grain of sand, or a burr on the spudger and you're risking a potential cell rupture and potential fire.

    Just use a bit of heat ( not a lot! ) to soften up the glue and it'll come away with the plastic pull tab.

    Paul L Daniels - Réponse

    These instructions don't mention putting the 2.5mm screw back in. I found this very challenging because it is so short, so very difficult to line it up to get it back in the hole, and very easy to drop it inside the phone. Take care.

    Richard Bebee - Réponse

    Apparently it's not necessary to remove the battery, but try at least (I'm curious).

    The battery was stuck (too much glue) and the plastic tab didn't help, and I ripped it...

    So I use the plastic opening tool on the other side to remove really gently the battery, it was really really stucked with the glue... Now I'll know when I'll need to change it.

    Adhesive was holding battery VERY firmly, so during this step I used a hair blow dryer on low setting to carefully heat up the device.

    The new battery from iFixit already had the cable properly folded, but before inserting the battery I used the plastic tool to press the fold closer to the battery body.

    Before inserting the battery I put the contact clip into position. It has a hooked shape on one side which fits between the socket and the folded battery cable.

    misc - Réponse

    When inserting the battery I started by guiding the folded cable into position against the side of the contact clip, then proceeded to lay the battery in position.

    When pressing the battery connector into the socket, the first time I pressed from bottom to top. That didn't work because there is a little tab at the top of the connector which must fit into a tiny notch or else the connector won't lay flat properly. Pressing the connector from top to bottom worked easily.

    Needle-nosed tweezers were very helpful when lining up the screws. After everything was reassembled I tried powering up the device, but the battery had insufficient charge. I plugged it in and immediately the screen displayed a battery with a thin red line (illustrating no charge). After 25 minutes the device sprang to life and indicated a 10% charge. At 70 minutes the battery indicated 30% charge, and at that rate should be fully charged in under 4 hours. It's fixed!!

    Strictly speaking re-assembly is NOT the exact reverse of dismantling. In particular do not put the battery in and then try to plug in the connector, Rather, start by plugging in the connector (having straightened the ribbon-wire attaching it to the battery) and only then re=position the battery on its (gluey) base. Also I used a wooden cocktail stick to position the antenna connector correctly (pushing the stick through the hole in the antenna piece and into the threaded base where the screw will eventually go) and then I held it all in place (temporarily) with a tiny blob of Bluetac until I managed to successfully withdraw the cocktail stick and fit the proper screw.

    Make sure not to pry too much under the flex cable because you will likely damage the gold / silver shining adhesive tape that is located beneath it.

    The guide is missing a comment on this and one would not expect the tape there. Check out the photos of step 10 to get an idea of how the tape looks like.

    I assume this to be some kind of head-conductive component.

    It won't be much of a problem if you damage parts of it though.

    But if you peel off / coil up too much of it, it could get too big and the flex cable could get damaged when it's pressed against it.

    Couple of ways to get rounded-out-head screws;

    1) use a tiny drop of super glue on the top place your screwdriver on the drop/screw, then sprinkle a bit of bicarb-soda on to the wet super glue, it'll harden very rapidly and form a fillet; wait a minute and you should be able to then unscrew the screw.

    Be VERY CAREFUL when doing this, because you don't want to have superglue wicking between the screw and the circuit board.

    Perhaps practice on some other things first.

    I've removed several like this before; frequently I find the culprits for rounded out slots are ham-fisted people trying to do their own repairs in the past.

    Be careful about the very small spring contact that is under the shield and around the 4.8 mm screw - it can spring out when the shield is removed. It must be reinserted prior to installing the shield, with the thick part up and the spring in contact with the gold pad to the right of the screw hole in the case.

    Steve Noland - Réponse

    INCREDIBLE! Steve this probably happens to people all the time. The "very small spring contact that is under the shield and around the 4.8 mm screw" I will elaborate on. It's not so much around the 4.8mm screw as it actually part of the assembly where the 4.8 mm screw is tightened. I added an arrow to this picture to visually illustrate:

    I had no wifi at all until this was present. I had overlooked the piece and spent hours trying to figure out where it went. BIG THANK YOU to Steve for his comment. After fixing, my wifi was perfect.

    Jimmy -

    When re-assembling, start off with replacing the 4.8 mm Philips screw first, then the 2.3 mm. This is to ensure there is no mix-up, and avoid rendering the LCD and digitizer useless. Steve or someone -- can you explain what is meant by this? My LCD and digitizer now does not work, but I don't think I have any screws in the wrong place.

    Confirming this. It's not in the description and it came out when I disconnected the screw. At first I was unsure where it came from, but when I reassembled the phone, the yellow screw didn't make contact, so I realized the washer had to go under the contact plate.

    On my phone the "washer" that the 1.4mm screw goes into I think is actually the mounting post that had come detached.

    The "washer" that a few of the commenters have mentioned isn't a washer nor a broken post. It is a circular nut that helps the WiFi antenna get a good connection to the logic board. It is part of a sandwich: 1.4mm screw head WiFi antenna logic board ++ circular nut. I held it in place with tweezers and then screwed the 1.4mm screw in. Don't lose this nut!

    Chris - Réponse

    This screw is supposed to tie into a very small nut that sits under a small u-shaped tab in the EMI shield that is fixed to the PCB. Maybe that nut has moved or got lost. I recommend you to lift that small tab to find it because if loose it could create a short-circuit.

    But that screw/nut is absolutely not essential to the LCD. It should work without it.

    I used an elastic band pulled taught over the blade of a flat headed screwdriver to hold the nut (beneath the yellow screw) in place. Alternatively I was thinking of carving the eraser on the end of a pencil into a wedge shape to do the same job when tightening the screw on reassembly. Just needs something to grip it in place to stop it spinning.

    Lee Noble - Réponse

    A note about screw management: ALWAYS remove screws from left to right if you are just putting them in order of removal on a magnetic trey, it helps with re-assembly. If you can, I recommend getting a magnetic white board and writing the size of the screws on it and categorizing by that, it makes it way easier and you won't ever have to worry about putting the wrong size screw in anywhere ever again.

That jumper is next to the right upper corner of the headphone/volume button plug (yellow marked in step 17 of relacement guide), you can see it in the picture as two silvery dots. If your prying tool sits on that jumper when levelling the plug off, it is history. I took a ampoule of conducting silver liquid, but instead of shaking it I took some of the sediment out with a thin wire and aplied a tiny blob over the two remaining soldering pads left. And alas, it worked ! Front camera is ok again. Thanks to those who found out about that jumper.

    On reassembly, be really careful when reattaching the digitizer cable - the cable breaks very easily, rendering your nice new display useless.

    What is the correct length of flex (ribbon) cable for the Digitizer cable and the LCD cable? I've threaded the cables correctly through the mid frame, however, I keep encountering the same issue. Once I've tried seating the cables into the sockets, the Digitizer cable is too short by approximately 5mm. I've tried several different makes of the front panel display (front screen replacement) but have encountered the same problem with each and the supplier, stating each have been 'defective units'. It just feels a stretch to believe I've been unlucky in purchasing 4 that have all been defective. I can't check these against the original (Apple) screen, as it was too damaged and the removal process of these iPhone 4 screens is a nightmare. Any help is appreciated

    My setup was nothing like this. The headphone jack, top microphone, and front camera connections were not in these locations. Rather, they were on the logic board below the main camera connection. Furthermore, the logic board was held in place by a Phillips head screw that was hidden under a small black piece of tape. This screw also held the small gold connector tab. Additionally, the bottom of the logic board was held in place by a Phillips head screw.

    I have found that the easiest way to remove these standoffs is to loosen them with a 2.0 or 2.3 mm standard (flat) blade driver bit. Then, once it is loose, you can either loosen it the rest of the way, or for better control, insert your pentalobe driver into the center of it and loosen it the rest of the way. If your pentalobe driver won't turn it, then it is not loose enough, or the end of one of the small screws has broken off in it (actually fairly common).

    Best of luck to you! Just ask if you need more info!

    1. the final attachment is held on vertically to a chassis wall. use a small flat object, perhaps your fingernail between the black foam and the vertical wall. it is a trick to pull the final piece off the wall without damaging the black foam. mine is now damaged and will not likely re-stick.

    it may not normally be a problem since your new piece may come with a rubber sticky thing. but in my case, i was removing a good one to replace a damaged one on my other phone.

    I thinks it's better to leave the earphone speaker attached until the power and sensor cable is removed from the phone. The speaker can then be carefully peeled off so that the foam and glue are retained on the speaker for reattachment to the new cable. I peeled it off with the cable in place as shown in the instructions and it tore the foam.

    I totally agree that it is better to leave the earphone speaker attached until the power and sensor cable is removed from the phone. It is too hard to see where to pry and not to pry and I also ended up tearing the black lining.

    • Retirez les deux vis cruciformes #000 fixant le support du bouton de marche à la coque extérieure.

      • Faites très attention aux nappes de l'écran, qui peuvent empêcher d'accéder facilement à la vis de droite. Les nappes s'endommagent facilement.

    • Retirez avec précaution le support du bouton de marche et sortez-le de la coque extérieure.

    • Ce support est en aluminium coulé et se fissure facilement. Procédez avec prudence.

    The power button bracket has 2 screws that need to be removed, there's no mention of them in this tutorial.

    DarkCloud - Réponse

    Agree with the above: Two screws holding the power button bracket are not mentioned and must be removed. One of them is very awkward to reach due to the digitiser and LCD cables being in the way. This was the trickiest part of the whole procedure for me. Otherwise a wonderful guide. Thanks so much.

    Martin Young -

    Yes, I second that

    ghostmju - Réponse

    When removing and/or re-inserting the right-hand screw, I damaged the LCD cable and the phone did not work. Fortunately, the power/sensor cable was from a donor phone and I also was ale to use the display assembly from the donor phone as well to a good conclusion. Be very careful to fold the LCD and digitizer cables down out of the way when accessing that screw, or if you want ultimate protection, consider removing the display assembly before removing the power button.

    • Utilisez une pincette pour extraire le corps de la prise casque de la coque extérieure.

    • Soyez prudent et évitez de déchirer la mince nappe.

    The instructions here should specify that the headphone jack is attached to a ribbon cable. And that said cable is *extremely* fragile.

    I didn't even feel resistance when removing the jack and now I have to replace that assembly as well. :(

    Same problem with tearing the headphone adapter ribbon. Didn't even notice it until I turned over the phone and the jack part fell out and hit the floor.

    mattabuxton - Réponse

    No need to remove fully the headphone Jack..

    Just pull it up from the upper part.. that's sufficient enough

    to remove the power/sensor cable .

    • Saisissez la nappe d'alimentation et de capteur près du microphone et éloignez-la du panneau frontal, en prenant soin de ne pas la déchirer lors du processus.

    • Prenez note du microphone rectangulaire en or attaché verticalement à la coque. Veillez à ne pas le détacher lors du retrait de la nappe.

    • Si vous remplacez la nappe d'alimentation et de capteur par une nouvelle unité, utilisez le bord d'un outil d'ouverture en plastique pour décoller le bouton de marche de son support métallique.

    • Assurez-vous également de transférer la pièce en mousse/le filtre UV du capteur de proximité adhérent à l'ancienne nappe d'alimentation et de capteur si la nouvelle n'a pas cette pièce. Celle-ci ressemble à un petit carré et peut être décollée avec une pincette.

    • Transférez le support sur votre nouvelle nappe d'alimentation et de capteur.

    There is a small plastic 'box' covering a few components that must be transferred to the replacement cable assembly. Also, there is a small foam 'frame' that covers a sensor (proximity?) that must be transferred to the replacement cable assembly.

    Blarg - Réponse

    I'm having constant problems with those cables. It came to the point that I took that cable out of my personal iphone and put it back and after that the proximity and light sensors don't work. And I tested 10 cables on 3 different phones and I can't get it to work. Do you have any idea what I may be doing wrong? The power button work, so it's just the sensors...and I really can't believe all my cables are bad because I had a good one, took it out, installed back and it stopped working. What can I be doing wrong during the installation?

    grze -

    I had the same problem, grze, and after lots of frustration and trial/error I realized that the foam frame that Blarg referred to was this 0.5 cm plastic/rubber piece that was stuck on the original power and sensor cable. It's a rubber frame with a cool-looking reflective glass screen in the middle. If you transfer that onto the proximity sensor on your replacement cable (which doesn't come with it)... it should work perfectly.

    Rich - Réponse

    Is there a place where you can buy these foams that you put on the proximity sensor?

    When I remove these from the original one, they just don't stick anymore.

    Any Ideas? (I don't want to pay 5$ for a single foam)

    Ruben -

    Anyone have information regarding where to buy the proximity sensor filter, preferably in the USA? The guide just mentions a shroud but doesn't have a picture for it and now my proximity sensor isn't working during calls.

    MannyF - Réponse

    After installing a new sensor cable, the proximity sensor was not working, but the sleep button and also the mic noise reductor too. Luckly I found the old cable in the trash and transplanted the square foam to the new one and got proximity sensor working again.

    Drfrag - Réponse

    My power button stopped working. Figured it was mechanical, since it didn't "click" anymore. got a new power/sensor cable, replaced it using this guide and now the proximity sensor is not working. I put all the rubber foams back in their places, made sure everything was stuck where supposed and it is still not working. If you are replacing yours, be very careful during this part!

    Andrei - Réponse

    "Also be sure to transfer the proximity sensor shroud/filter adhered to the old power & sensor cable if your new one does not already come with one."

    It took me a while to figure out what they were referring to. Almost threw it out since it was stuck to the old flex! It's the little rectangular plastic piece with a little loop at the top left. You can see it in the middle of the power flex displayed in the previous step's picture. It seems it keeps the proximity sensor in place. It would be helpful if it were circled.

    Patricia Z - Réponse

    This step is crucial to getting the proximity sensor back into working state:

    There are two sensors on the power and sensor cable peeping through the front glass of the phone. Looking at the front of the phone, the sensor on the right is a square and dark one, whereas the sensor on the left is a round golden one. The square, dark sensor on the right needs to be covered with the proximity sensor UV filter foam sticker everybody is talking about. The sticky side needs to be applied directly to the sensor. You can get these stickers at eBay. Don't apply the sticker to the front display glass of your phone. Don't apply the sticker to the golden, round sensor.

    i want to say that my problem was it is easy to OVER TIGHTEN the screws holding the bracket over the new power button . the new button will not operate as it is always pressed in so I fixed this by using a drop thread lock then putting the screws in and backing them back out slowly testing the button the whole time till the power button worked . let set over night so the thread lock will dry and bingo it worked . I read many "use paper" and "use rubber band" that is not fixed . I am a believer in the project working not jury rigged .....

Be careful removing the headphone adapter, the ribbon is very easy to rib with the metal brace beneath it.

Now this is more helpful, than the power button repair guide that they gave us. This one still kind of leaves me hanging on how I'm supposed to put the silver button back into the hole so that it makes contact with the orange dome(aka the powerbutton).

Anthony - Réponse

I replaced the Home button and the Power & Sensor cable, along with battery. Let me explain some caveats with ifixit's parts (OEM Apple parts):

-The power-sensor part does not include a new gasket/filter for the sensor- recommend tweezers and care.

-The power-sensor cable needs the foam pad transferred with the adhesive- extreme care with removal.

-IF the power button isn't working it is likely the cable, not the button.

-I used a small ice cube tray.

-It took me an hour (I had to get up and walk away...frustration factor high with the delicate flex cables and adhesive). Lit magnifier is welcome. Definitely use a spudge stick.

-I broke 2 of the 4 shield/antenna tabs that you need to tuck down from the speaker on re-assembly. I didn't force them, but so easy to press too hard in seating the speaker.

- I do repairs on a grounded-ESD mat and wore wriststrap.

-Right screw on the power button brace is PITA to access...careful pressing on the display flex cables to access the tiny screw. Magnetize your bit!

Great guide and perfect web site. It is extremely easy to find what you are looking for and order the components you need.

Be careful in the step after removing the battery connector and then the battery, you forgot to mention the small springed contact piece below the batt connector, sharing the same screw. I dropped it on the floor after handling the batt but found it and figured out how to place it in the re-build. Anyhow, nice guide 1.5 hrs work wo to go on replacing the button circuit.

MAKE SURE YOU HAVE THE SENSOR FILTER TRANSFERRED!!! The guide does NOT make it explicit!!! Everything's ok except the proximity sensor. Not looking forward to take it apart again. The new cable may rip!

Power button wouldn't click so I followed a different guide (very similar to this). I only realized now that proximity sensor wasn't working. It doesn't bother me too much, but I may try to fix it. I had to reopen it to fix my WiFi after a little piece fell out and I replaced it with aluminum foil. A small piece of plastic fell out that looks like the proximity sensor. How does it get affixed back to the power bracket?

My main problem is that my pinhole microphone (next to the headphone jack for speaker phone and audio in videos) doesn't work anymore. It gives me a hissing sound. A guy at a fix-it store seemed to tell me that it was related to the power bracket and things might need to be shuffled around because it was very unlikely it was damaged. Does the little metal square on the power bracket provide power for the microphone? Is there anything specific that needs to be touching other parts in there to make it function properly?

If you could respond to I would be very grateful.

after the breaking of the switch power button I proceeded to replace the flat. After putting everything I have, however, found that the hands-free microphone is not functioning.

I disassembled everything again, double checked but it seems to be all right (power button and proximity sensor are ok)

I can not understand what could have gone wrong.

I should add that the hands-free microphone with the old flat was working at 100%.

I have already ordered a new flat, because maybe what I have mounted is defective ... I doubt it but I hope so!

Does anyone have ideas or suggestions?

Note on the screw template - Step 20 should be Step 22, and Step 22 should be Step 24. I also used Scotch Removable Double Sided Tape to hold the screws to the screw template page. Really did the job!

Verizon CDMA iPhone 4? You should review the iPhone 4S instructions (Remplacement de la nappe d'alimentation et de capteur de l'iPhone 4S), as I found some of the screws and components on my Verizon iPhone 4 to be more similar to the iPhone 4s (especially the cable cover and logic board connectors).

Awesome guide- first time I ever cracked open an iPhone, and it was a total success!

sgarst - Réponse

This guide is very good. I could replace the power/proximity sensor/mic cable successfully using this guide. Note that the two screws on the power button bracket should not be tightened all the way in - that jams the power button. I thightened them all the way and then loosened them (probably 270 deg anticlockwise) until the power button gave that distinct 'click' feeling when pressed.

pole star - Réponse

Successfully replaced the cable, just a couple of tips to pass on:

1) When transferring the pads and spacer, it is possible to get by with reusing the original adhesive if you're very, very careful. I used a sharp single-edged razor blade to carefully lift between the adhesive (a double-sided tape) and the cable. A small X-Acto knife blade would probably work, too. As mentioned elsewhere, don't even think about using crazy glue, as the fumes will attack the various metal contacts in the phone and create a real mess.

2) Read all of the guide comments here before you start. There's a lot of great tips that will make things easier and save you from damaging parts.

3) I replaced my battery at the same time that I did the cable replacement, old battery was five years old and no extra labor since the battery comes out to do the cable replacement.
