    After reviewing the steps I decided to follow this guy's advice and left the battery in.....one less item to possibly foul up. I don't know if it made it any faster (first time to open my phone, so nothing to compare it to) but I can say that my phone is charging for the first time in 6 months :D

    1) This is doable but not easy, quick or without risk.

    2) If this is your 1st time, the whole process can take >2 hours (half of it reading this fixit manual and notes, which I highly recommend!)

    3) I highly recommend placing a large, thin clean white cloth on the table. This prevents screws from rolling around and you will clearly see anything falling out.

    4) If you have them, use tight surgical (latex) gloves. This prevents you from greasing up contacts.

    5) Have e.g. a big old egg box ready, so you can place the screws in order (and maybe write step/screw size on the side).

    6) I bought my display from "Generic" on Amazon ($20.36). Screen works fine and tools were ok but not great (screw drivers do not withstand force needed to unscrew some).

    7) I had my own 2mm Phillips screw driver and a 2.4mm flat (for the big screws).

    8) Have a nice cold beer by your side! Good luck!

    After seeing the comments about trouble finding the carrier, I shut down the phone, did a soft reset (by holding the power and home buttons until it started and then shut down and stayed off), and removed the SIM. After the repair, I replaced the SIM and plugged it in to the charger. It started up and found the carrier (Verizon, as it happens) immediately. I would guess that only the soft reset made a difference, but I did both.

    The physical battery replacement went off without a hitch, and saw that the phone had no network connection, but also had no way to unlock. The slide lock said "Slide for Emergency Call" over my custom wallpaper and sliding would give the passcode screen, but it would reject the 6 digit passcode (it would buzz and go dark after the 4th digit, re-awakening and putting in the last 2 would indicate bad passcode). Very frustrating! I get it into recovery mode and convinced iTunes to "update" the OS, but it still didn't let me in. I performed a restore to fully factory reset the phone, and it worked! Sort of... the start screen kept being replaced by "Temperature - phone needs to cool down" but it's cold. Temp sensor is on the battery and returning to old battery fixed it. New battery is bad, and phone is wiped. Fun night.

    I'm going to guess that disabling the password might save you from a similar fate. So, I'll suggest BEFORE YOU START, backup your phone and disable the passcode. Good luck.

    I didn’t find this particularly difficult, even though I’m pretty inexperienced at this sort of work. I watched the video overview to get me going and then followed the steps in the guide. My tips would be to keep the screws and parts organised as you dismantle, and ensure you read all the reassembly tips as you go; it’s easy to skip over them.

    The replacement panel I got had two sheets of protective plastic on the inside and one on the outside. I used a toothpick to carefully lift and peel the two inside sheets off. One small one was over the lens on the inside. The other was over some large brown sheet of unknown function (though I think it goes over the battery). When I peel that away, some of the brown material tried to lift of with it, so be very careful.

    The bottom screw on my phone was locked with some thread adhesive, and required more force to loosen it than I expected.

    Even after removing the screws, the battery connector was rather firmly seated, and required a fair bit of persistent gentle prying with the opening tool before it came loose.

    The battery connector is attached to the battery. You're not going to completely lift it out and remove it. It pulls out from the socket you can see in step 5 picture 3. The pressure contact (little black and gold thing) will probably just slide out from under the connector. Not a problem.

Quand les deux vis du contacteur sont retirée, attention au moment de débrancher le contacteur: cela va faire bouger cette pièce qui ne doit pas être abîmée ni tordue. Au remontage, il faut bien la remettre en place sous le contacteur de batterie: il est tout à fait possible de mettre d'abord le contacteur, puis de glisser la petite pièce au dessous pour qu'elle soit bien à sa place, le trou en face du trou de vis et du trou du contacteur. En remettant la vis, la pièce tient bien en place. Elle doit bien continuer à dépasser de manière a faire contact avec le dos de l'iphone.

    The Liberation Kit Philips head screwdriver strips the battery connector screws! It stripped the ne 1.7 mm Phillips screw circled in red in the photo above. I was able to remove the other screw, then I lifted the battery connector off while the red screw was still in position and wound the connector around in circles while lifting upwards and managed to unscrew the stripped screw. Advice, find a decent philips heard screwdriver for the internal screws like the two found on the battery connector.

    remsta - 回复

    Bottom screw was totally stuck, nothing could budge it. I removed top screw, heated up battery with hair dryer to release the glue, pulled it out using the spudger. Lifted up the metal plate thing (after taking out the ground piece and putting it aside). Cut off the flexible bit between the plate and the battery and twisted the plate around the screw as you did.

    Well, the screw eventually came out—but only the top half! Yes, it split in two. Then the bottom half came out, still attached to the thing it was screwed in to (a sort of barrel).

    I put the new battery in, put the bottom half (with the barrel) of lower screw back in its original position, replaced the ground piece and positioned the new plate over it, and screwed the top screw back in. Then put the top half of the lower screw in and tightened it.

    Et voila!

    Extra: It was helpful to discover that the 1.5 and 1.7 mm measurements refer to length of screw, not size of Phillips head.

    Claudia Baragiola -

    When reassembling, use EST tweezers to get align the pressure contact over the top screw hole. using the pointy end of a spudger to assist: put the point through top screw-hole on the battery connector, then through the pressure contact and into the screw-hole. this will help to keep the small piece in place while re-seating the battery connector. Leave the top hole spiked as such until the screw in the bottom hole is gently fastened. Remove the spudger and replace the top screw.

    The pressure connector is the battery connector under the silver plate. BE CAREFUL. It seems like it'd be really easy to tear that pressure connector out without meaning to.

    The phillips head screwdriver provided in the ifixit repair kit does not work well this these two screws after my first attempt at unscrewing the screws became stripped. The 1.7 mm phillips screw gave me the most trouble. It took an hour to unscrew after the screwdriver from the kit stripped the screw. I used a piece of masking tape over the screw for grip to loosen it, then used finger nail clippers as pliers to unscrew. I would recommend investing in a better screwdriver for this one step. Assembly is otherwise simple and easy.

    Here's a tip if you're having trouble removing the 1.7 mm screw. I had real problems removing it – the 1.5 mm screw came out easily using a Phillips #000 screwdriver but I almost stripped the 1.7 mm screw using the same screwdriver. What I did instead was use a flathead screwdriver from the iFixit pro tech toolkit I got, the one with a "–" sign and 1.0 size. That worked perfectly!

    I would agree that a decent magnifier would help as the screws and components are small.

    Also take necessary precautions to ensure the screws are not lost or mixed up.

    Other than being a bit fiddly (particularly the earth connector), the only challenge I had not covered was that the battery was fixed with glue close to where the connector is and despite releasing the battery along the side, I couldn't get the battery to lift out using the tab. In the end I had to use the plastic tools to gently lever the battery away, working from the outside edge and ensuring I wasn't levering against the volume control buttons.

    The new battery is in and following the advise given, I hard reset the phone and all my usual functions are now running... and if this £18:00 fix gives the phone another year or two of use, it will be well worth the effort.

    I've gone through this process twice now. I found this video also very helpful: https://www.youtube.com/watch?v=nYYdbk3U...

    The little contact thing that sits under top screw is always the biggest hassle to fit back into place (I do it after attaching the battery cable) with tweezers from ifixit.

    My personal tips:

    - plan that the incredibly tiny screws or the top-screw contact thing, might get away from you. so work in a space where you can find them easily. Not over carpet, etc.

    - I use strips of tape on a piece of paper to secure the screws while they are out, and position them so I know which one goes on top of battery connector, and the one on bottom.

    - If you have access to a spouse's/mate's iphone, in Accessibility settings there's a Magnifier option (triple-click home button) which does an amazing job at magnifying stuff at a circa 4-6" distance. Lacking any good magnifying glasses, this feature helped a lot. https://www.imore.com/how-use-magnifier-...

    The black ground contact needs still more "flagging." This is a simple metal strip that is attached ONLY by the 1.5mm (upper) screw. It will help if you look at it before you remove the upper screw. Notice the gold contact arm and point. That contact point must be in a plane above every other surface inside the device when you replace the battery connector, because it makes a ground contact with the metallic inner surface of the device back plate.

    When I replaced it, I used the Pentalobe driver to line up battery connector and ground contact with the screw socket post. I then attached the 1.7mm (lower) screw loosely, removed the Pentalobe driver gently, and inserted the 1.5mm (upper) screw into the assembly. There is a tab on the ground contact that helps it align properly once pressure begins to applied. I completed driving the upper screw, pressing lightly with the spudger on the battery connector plate to make sure it was seated on the pressure contacts. Finally, I completed driving the lower screw.

    I didn't find any need to remove the pressure contact. I just pried the battery connector up (gently) with a spudger and left the pressure contact in place. Connected the new battery and aligned the pressure contact screw hole. Replaced the screws, finished reassembly and all was good.

The plastic and "gold" "plug" was slightly askew on the metal plate, which meant that when the plug was inserted, the screw holes (step 4) were poorly aligned.

    I managed to pull everything back into line using the screws, but the QC on these replacement batteries is a bit suspect.

    Guess what happens when you rotate that ground connector 180 degrees...it grounds what I deduced to be the heat sink of the power amplifier for the speaker! So it is silent. It took me a couple of attempts to discover this as I was distracted by the new speaker not sitting down properly and a little dot of stuff under the main connector stuck to the pins. The latter was cleaned-off with a pin under 5x magnification followed by some isopropyl alcohol.

    I suggest that Step 5 is more explicit about the orientation of this ground connector. It's only obvious after a really close look and if one has a lot to do like I did, it's a long time before one comes back to this step so the correct orientation is not obvious.

    Michael Scollay - 回复

    If you magnify picture 4 or picture 5 twice, you can view the ground clip under the blue tool. You need to reinstall the ground clip with the copper color prong facing "up." I believe the ground clip is what many are calling the "pressure contact point" because the copper prong of the ground clip does indeed have pressure asserted to it when it contacts the back cover of the iPhone 4s.

    The hole in the pressure contact aligns with the top screw. The IFIXIT tool kit I bought contained a black sharp “thing” that I used to align the pressure contact with the top screw hole. I used this tool to align the bottom screw hole also. I put the bottom screw in first but did not tighten it all the way. A good magnifying glass with a light helped a lot. Tim

    Tim - 回复

    Aligning with the black pointy “thing” definitely helps. Also, the small copper end of the contact piece is supposed to stick up once attached, to make contact with the back plate of the phone after re-assembly. The piece slides under the silver metal plate, and the the pointer can be used to align the silver plate hole and the black/copper plate hole in place for the screw.

    Yes, there did seem to be a lot of glue holding my battery in. At first I was afraid of breaking it, but after reading up on the subject I've learned that it is okay if the battery gets a little deformed. Due to the nature of the battery it will still work if slightly deformed.

    I found the plastic pull tab to be useless. Peeled pretty much the whole battery out from the left side. Used a probe to "break" a few strands of glue to help. Just watch the connector and ribbon cable in the lower left corner as you pry up so you don't crimp them or damage them.

    DO NOT remove the battery unless absolutely necessary. If the battery is removed from the phone, DO NOT reuse it, ifixit does not seem to understand the importance of safely handling the battery

    Tom Chai - 回复

    Tom you have never been so wrong. Removing the battery is the FIRST step ANYONE should do before repairing or attempting repairs on their phone. The iPhone has many different grounding points in the phone and having electrical current running to it poses a massive risk, especially with ESD (ElectroStatic Discharge). People, PLEASE make sure you remove your phone's battery FIRST before doing any repairs. Use a plastic, not metal, spudger, after unhooking the battery from the logic board, place the spudger along the right side of the battery NOT under the volume buttons, about an inch and a half lower (two roughly if a sim card is present) and start prying it up using the frame as the fulcrum, as you start to lift the battery from the adhesive make sure you slide the spudger farther under to get even contact so you do not damage the battery.

    Prestige Computer Solutions -

    Try a used plastic credit/gift card to apply gentle pressure to lift the battery out of the phone, the short edge of the card fits within the gap on the logic board side between the battery and video cables. You can also use it on the opposite side if there is room between the battery and iPhone frame. This has worked on all of the 4 and 4s models I've replaced screens on.

    I offer an alternative image if interested.

    Hello! My clients iphone 4s:n battery connector broke, when i tried accidentally take the battery out with a plastic tool from the wrong side.

    Connector detached completely, so that the two middle ironcensors came with it and was stuck to the connector. When i screw the whole connector back to phone, it works with battery power, but the batterys downloading doesnt work. Are these two middle censors that are stuck in the connector exactly the ones that should be charging the battery? Do you know how i can fix this? I have already bought electrical conductor glue, but should the parts be cleaned somehow first? And how can i fix it, when the center metal sensors on the system board is also attached to the battery?

    How can i clean out thiskind of part with windex? I have purchased almost all of the possible tools from iFixit and the electrical conductor glue i bought somewhere else. (http://www.ebay.com/itm/300915727408?ssP...)

    Please, Please, PLEASE avoid using probing elements to try remove batteries. I have had dozens handed in to me with punctures and two that actually started smoking due to people trying to prise the battery out. DO NOT DO IT.

    The best way I have found to remove the battery is this process;

    1) Try remove it with the pull tab directly, some will come out, some will not. Do NOT use excessive pull force else it'll deform the battery and reduce the capacity.

    2) If the pull test didn't work, then get a hot air gun on medium and warm up the area around the battery for about 30 seconds, focusing on the perimeter of the battery. If you see ANY popcorn'ing then you're too hot, you don't want to cook the battery.

    2.1) Wait about 30 seconds for the heat to now wick underneath the battery to soften the adhesive.

    2.2) Now try pull the battery up, the extra heat should have softened the glue that you can remove the battery without excessive force and without sticking objects under the battery.

    The battery was incredibly hard to remove. I slid the spudger underneath the battery from the right side as far as it would go. Then, I worked it from the bottom to the top. The battery still was adhered and wouldn't budge using the pull tab. I wound up leaving the spudger underneath the battery at the top and then pressing down on the bottom of the battery to get leverage. After a few strong pushes, and then swapping the top and bottom in the last sentence, the old battery came loose.

    I used tweezers to hold the tiny screws and align them with the screwdriver head before taking the screw to the destination hole.

    One more tip.. if you don't have any other cartons or containers convenient, use the box that the product comes in as a workspace for holding the tiny screws while you work.

    Stuck on searching after unplugging and plugging in the battery?

    This is due to the date and time being set back to default. To fix this you will need to synchronize the date and time back to what it is currently.

    You can do this by either:

    - Connecting the phone to either a Wi-Fi network, Cellular Network (Mobile Data).

    - Connecting the phone to iTunes (It will synchronize the time automatically once iTunes is opened and can detect and access the iPhone).

    Once the date and time is synced you will need to turn airplane mode off and one as it may display 'Searching... 3G' or if it still says searching (which most of the time happens if the sim card has a sim pin lock enabled on it) you will then need to turn the phone off and on.

    You really need to include information about the pressure sensor. It WILL inevitably pop out, leaving us wondering how and in what order it should be replaced.

What I did was I took out the battery, the tin plate above the cables, and lifted the dock connector. So I did not redo that much. I cleaned all contact surfaces as I had been told but chose to not do before.... I also took out the grounding clip by the battery connectors and bent it upwards quite a bit while also peeling away 2 mm of the black insulation material on the back of the phone to make sure the grounding clip connects well to the back of the phone. I also cleaned that surface with window cleaner, which is basically isoprypol alcohol as has been recommended.

    That power cable connector is very delicate. I managed to tear it just a tiny bit in the curve of the cable too. So I’ve got another part on order now. Apart from that the screen replacement went great ;) I’m not sure at which step the tear actually happened, it might have been during re-assembly when I was trying to get all these cables to stay on top of rather than go behind the motherboard. Realizing how easy that is to tear and keeping that in mind as you do this is important.

    I recommend that steps 20 and 21 are swapped. It's much easier to remove the wifi antenna flex from the board using the blue spudger if the board/PCB is still secured with the 4.8mm screw.

    Removing the screw first makes the PCB move up too much when you're trying to detach the wifi flex and can lead to mishaps.

    Ok so no fret here if you accidentally pull off the metal insert placed on top of the actual antenna. This step needs to be rewritten imo, the deal here is that there is an actual 'socket' looking deal underneath here that you need to lift up. There is a metal tab semi'glued' to that part of the antenna and it does come off easily, however all you need to do is press them back together to get them back, I believe it to be a range 'extender' of sorts.

    So your looking to actually lift up what looks a lot like a ribbon cable as well in this step. YOU SHOULD NOT HAVE A PIECE REMOVED IN THIS STEP, it's still in the case at this point.

    When reassembly - take care with flat cable, which might be pushing connector to side. If so - I found easy to put connector in place before tightening screws on step 23 and 22.

    Counter clockwise from upper right near power button:

    - Wi-Fi Cable from step 21

    - 5 cables near the camera from step 17.The ‘blue’ power cable underneath loves to hide. The ‘orange’ front facing camera cable can get kinked under the board during re-install (no more selfies on this phone).

    - Dock cable from step 9

    - Cell Antenna from step 11

    Go slow. Look twice.

    Pb-free solders have typical melting temperature around 200-220 °C so 200 °C is never enough to properly REFLOW the chip - you basically just heat the thing up which probably causes some deformation and helps to make the contact between pins again.

    As for real reflow, use 200 °C temp for first 90 sec (ideally you want to increase the chip temperature no faster than 3 °C/sec up to 200 °C), then ramp-up to 260 °C for 60 (max. 120) sec (this causes the real reflow), and then cool the thing down using 100 °C air for next 1-2 mins (or just leave it to cool down freely.

Then reflowed it with the given timings and temperature reduction. Works and I hope for ever.

    You can do this without any masking tape.. you can use a gair dryer, if you have a thermometer is better.. i have fixed 6-7 phone using this method. only one guy, every 3 months come for a new fix.. on that phone i can't do a permanent fix. this guy always go to ski, so the temperature broke the soldering and i have to reflow it sometimes.

    che chip have many little pin on the bottom side, reflowing it, you have to desolder and resolder for make it work..maybe the chip is broked, so for fix it, you have to buy a new chip, heat the old chip, take it off, clean the surface, put the new chip and reflow it.. is more difficult..

    you can do it for 30 minutes.. the chip will survive to the hot temperature.. i use 280-350°. the solder wire have the fusion at almost 300°C so you can do for 20-30 minutes.. i dont know if the hairdriver can reach that temperature..

    I cut back quite a few of the steps and did it slightly differently though

    I simply took the back plate off, moved the battery aside, took out maybe 5 of the screws near the top until I could pop off that plate that wraps around the top left. Once those were off the WiFi module was completely exposed. I took a razor blade and sliced the tape off the chip and took my soldering iron and ran it around in circles for about 5 minutes, VERY CAREFULLY I might add, since I never took the actual phone apart.

    Once it cooled off, I reapplied the tape, used the semi-hot soldering iron to adhere the tape back on, then re attached the plate, screws and backplate, fired the phone up... Wifi works like a charm now.

    This all took me 15 minutes tops.

Mille grazie, Andrea! I completed the repair thanks to your awesome Guide. Could it be you forgot to describe disassembly of the camera + surroundings? I took it out, too.

However, thank you,


Alex Holzhey - 回复

Feel free to describe...

floresc -

you dont need to take out the surrounding and the vibrator, you have just to take out the motherboard, so u dont need to do that..

the camera yes, you have to pull out. im sorry

reply to @Alex Holzhey

Thank you! i'm happy to hear this. and i'm glad to know that my guide is useful. anyway i have done a "copy and paste" for the first 20 steps, so i dont care about if something is the guide is missing..i think that if someone wanna try this guide, he have to know a little how to disassemble his phone. :)

Thanks again

I'd say first try the fridge method and the network reset before decommissioning your iPhone's hardware. Here are a few other things you can do to try and solve the wifi issue: http://www.copytrans.net/blog/how-to-fix...

It amuses me to no end that putting my phone in the freezer solved my problem (going on two weeks now). Can you explain the technical reason for that? You mention above it's a temporary fix, perhaps it is but it's been a LONG temporary so far.

I didn't have the tools for doing the reflow so I ordered a new WiFi PC board ($25 versus about $90 for all the tools) - so if the time comes, I'll just swap it out.

Thank you for your guide!

JamieClay - 回复

i think that under the chip there are some small point that have to be solder on the motherboard.. with a reflow you make hot and the chip will solder to the motherboard.. but probably this is wrong, i dont know why the cold temperature fix the problem.. maybe the chip works in a range of temperature that you fix using hot or cold air.. i only know that a high thermal shock will make this chip KO.

have you bought a new murata chip for the wifi connection?? and how you think that you can solder on the motherboard without a air gun?

it haven't a flex cable..

Andrea Giannone -

I ordered the full PC board with the WiFi and Bluetooth on it - no soldering involved. Anyway, I do appreciate the 'freezer' tip. I may never have to swap out the PC board, we'll see.

JamieClay -

Really? Only use a pentalobe bit once other wise it strips? Maybe with iFixits cheap tools, but get yourself a nice Wiha set and you'll never have to worry about it. I am a cell technician and have been using Wiha tools for the last 8 years, THE SAME SET I STARTED WITH 8 YEARS AGO! I bought a iFixit set, and the PH000 stripped the first day I got it. So I can only imagine how crumby the iFixit pentalobe must be. But anyway, good article, good pictures. Some people are making it out to be harder than it is. Just take your time, make sure you put the screws in a place where they will not get lost and you will be fine.

Hello guys. I fixed this problem just by reseting my phone in DFU mode.

here is a link that shows how to do it.


Serea Ionut Bogdan - 回复

Just wasted 3 hours with the DFU reset. Same problem persists. So frustrating. It seems like a hardware problem because I tried putting the phone in the freezer and the wireless worked for like 10 minutes. I'm confident this heat flowing would work, but it's a lot of work which tells me this is a hardware problem, but if that's true, then why did my wireless stop working immediately after installing iOS 7? That would suggest it's a software issue. What the !&&*?

miketkong -

Thank you Very much.

Step by step was excellent, I did not have the the insulating tape or rework tool. Used electrical tape to cover all surrounding IC's kept the board suspended for good ventilation all around and used a blow-dryer oscillating as recommended.

Reversed all the steps for re-assembly and instant WiFi on power up.

Thank you

Aung Khant maw - 回复

Hi. Try a reflow first. Change the chip is harder to do. Just heat it. If not work, you can try to buy a new one. This method is not 100% working, i have fixed something like 15-20 phones, 3-4 phones after 2-3 months need another reflow. And only 1 phone is unfixable

Andrea Giannone -

I have a question that Maybe some one has asked already, but I cannot see it: Can you do the reflow without removing the logic board and covering everything else with the tape to protect from the high temperature?

javi - 回复

If you use a small tool, you can do without any tape. I have fixed one simply putting under a lamp (table lamp) without taking off the back cover..

If you will use max 300c you dont make any problem to the mainboard.

For desolder a connector/smd/chip, you need 350-400c.. if possible remove the shield that cover the LCD/touch/camera/power/volume connector, and then remove also the black tape that cover the Wi-Fi chip.. remember to turn off the phone and remove the battery

Andrea Giannone -

Thanks a million! I bought the heat reworkstation on Amazon and was able to fix my iPhone 4s! I hope this fix lasts a while. I had been doing the blowdryer trick but that was only lasting a few days.

I had this problem for a couple of weeks and therefore ordered a new phone. When I removed the sim card (the phone was on and I was logged on to the sim card, i.e. could call etc) to put it into the new phone a noticed that the Wifi started yet again when the sim card had been removed. I do not know if this is only temporary or if the problem got fixed by removing the sim card when the phone was on but you could try at least.

Lori - 回复

hi, first try another sim, or try ytour sim on another phone, then check if the antenna cables are connetted on the motherboard, and remember that if you remove the battery, the date of the phone go to 1 jan 1970, and until you set che curent dat/hour, the phone dont recognize the sim card. try first to set the correct date/hour, then remove and insert the sim card. trust me, it will work

Andrea Giannone -

Hi everyone,

Did carefully all steps. Resoldering was made with a heat gun set on 250°C with an aluminum home-made nozzle.

Even all this, after it was mounted back, iPhone didn't start anymore. No image, no sound when plug. iTunes doesn't see it either and it doesn't appears in the USB tab in System Profiler. Tried to hard reset, but nothing. The only thing is the iPhone is getting hot.

A detail too: when I reassemble the iPhone, the antenna clips plug near the WiFi chips was unsolder - as for many user, I just put it back in place and it hold pressed by the little black metallic piece.

Do you have some recommendation to troubleshoot this?


niclet - 回复

hi, i have already seen this problem. sometimes the reflow can break the wifi chip, the problem is that when you turn on the phone, that chip became very hot and the phone will turn off.. i solved removing that chip from the motherboard and throw it in the basket!

Andrea Giannone -

Dear Andrea,

You nailed it! I unsold and removed the chip. Now the iPhone start and work smoothly. It just doesn't have its WiFi and Bluetooth functionality anymore.

Question: is it possible to get a new chip and resold it… for the experience and knowledge I mean! Or should I get a new motherboard!

Thanks again!

niclet - 回复

good! im happy that my guide works!

you can easly find the new chip on aliexpress or alibaba..

you can simply search on google "aliexpress SW SS1830010 Wi-Fi"

the price is very low, you can try to buy 2 or 3 chip, clean the motherboard using a solder iron and a solder flux and then clean with isopropyl alcool.

put again a solder flux on the motherboard, and with the solder iron (flatted) you can remake the solder points simpy passing the solder iron on the motherboard, then you appli again the solder flux, you put the new ic connector on the right place (i think is the most difficult part) and re-heat, maybe using 380-400°C for 3-4 minutes.. then you can check if the wifi chip is sticked good on the MB and try to turn on the phone..

P.S. check on the motherboard if you have all the solder points in good condition.. maybe when you took off the old chip you broked something or some "metal connector" between the chip and the motherboard

There is few steps missing actually.. But I did't wrote them down, sorry. Nevertheless, they are pretty common sense. ;)

ps. Actually this is second time I did that repair. Just after the first one, after a while wifi went down (bluetooth still were working). So I did those steps once again and wifi is up and running. Again.. :) Yiiiihaaaa!!! :)

ps1. my rework device Yihua 8786D when set on 300C by Thermo reader showed only 150 or so, but that reader also is Chinese crap so I don't give a dime that it's wrong. Anyone tried measure that? Should it really blow set temp?

Hi, I managed to fix the Wifi problem reflowing the Murata SS1830010 chip. After that I have an other issue... My iphone does not find my provider (is always searching)... and yes, sim card is properly installed and antenna is in place. Any suggestions?


Nikos - 回复

Yes, usually when you remove the battery, the date of the phone go to 1 jan 1970. Until you set the current time/date, you dont have signal..

Connect to the wifi, wait until the time will set correctly, then remove and reinstall the sim card. If dont work, reboot the phone without the sim, check the hour, then put again the sim card

I think yes but the wifi chip is a little bit harder to find. Is under the shield. You have to desolder the shield and reflow it. Check first if there is any antenna disconnected

Andrea Giannone -

WORKED !!!!!

Tried to cool and then Freeze it but no the easy way never works. popped the back off and just took a heat gun, a bit at a time, to the Murata SS1830010 chip in mention, but just enough so my finger would get burned when touching it, let it cool a bit turned on the phone and Whaalah it worked. Amazing thing this is almost like cold solder not sticking component's and having to be reworked. My hats off to you!!!!!!!!! ***** ;-)

we have all schematicts, and all solutions for fix any kind of problem, and i decides to share our "secrets".

this guide is the easy way to fix this problem at home, is not workin 100% but the method is correct..

if you read all the guide you can discover that this is a semi permanent fix, the right way is to replace the chip, but without a professional machines is impossible to so, and is very hard..

Great Guide! It works! This is the FIRST time I dissembled an Iphone ever and it surprised me, that it worked for me right away. Spending 3 hours to repair my Iphone 4s is absolutely worth it. During repairing there were some difficulties but finally my WIFI works again. It was great fun to do it! Thanks a lot!

Xia - 回复

WORKED JUST FINE for me. I used a general-purpose heating gun (NOT a hairdryer). The parts of the logic board not interested in the reflowing were protected with Kapton tape and sheets of glass-fiber material. Temperature was set at 185 C for 5 min and checked with a thermometer close to the chip to ensure no over-heating was occurring.

Francesco - 回复

Anyone a suggestion?


zzepposs - 回复

I have been repairing several phones and this is one of the most craziest fix to try (I thought). I already tried all resets and bla bla bla. Wi-Fi stayed grayed out and BT was not working.

I did take the motherboard out but didn't secure or cover it with any tape. Tried above method using hot air blower in some random temperature (I guess it was about 150-300'c), for ~3 minutes...and it worked! Wi-Fi and BT are back in business. Amazing :)

Great instructions. Many thanks!

Debbie - 回复

You have first to try a new screen. Maybe you damaged the flat of the lcd.

If the new screen will not show the image, you have broked something on the motherboard. You can figure out but is not simple to fix a motherboard if you dont know what are you trying to do.

Anyway im pretty sure that you broked tour lcd

Andrea Giannone -

I am convinced from all that I've read from various sources that this is an Apple engineering problem. It apparently is caused by some kind of temperature sensor in the iPhone triggered by an iPhone iOS update. Unfortunately this has never been resolved by subsequent iOS updates. I'm up to version 9.3.2 and Apple still has not addressed the problem with an update to iOS.

The best permanent solution I've heard of is to replace the WiFI antenna component BUT this is too much work.

Instead I chose a simpler (possibly less temporary) solution to just cool down my iPhone to trigger the temperature sensor logic in the iPhone.

Do not heat up your phone as some people have suggested. "Thermal Cycling" is bad for your phone. I've been able to reset the temperature sensor in my iPhone 4S by putting it in the freezer (in a zip lock bag) for about 15 minutes. It may not be a permanent solution but will re-enable the WiFI until the temperature sensor triggers the WiFi to shutdown again.

Vatta Far I - 回复

are u kidding me in this .. i mean how can anyone do this coz we r not experts ok and we dont have the right tools... this demonstration is nothing bt a headache... ur only gonna damage ur phone in the end.....

memyself20051 - 回复

The root of the problem being solved is that the WiFi/Bluetooth chip is becoming dislodged, as can happen when a phone is dropped. Forces on the chip during a collision pull the chip away from the board, creating micro-fractures in the solder connections. This can cause the WiFi (and Bluetooth) to work intermittently. To be clear, there are other reasons that your WiFi might stop working, and you should try to Reset Network Settings before attempting this kind of expert repair.

Why would temperature cycling help? Any time you heat or cool something it will expand or contract. This will cause the metal connections to move - the amount of movement may not be enough to be visible to the human eye, but enough to close the gap from a micro-fracture. This is a temporary fix because it has not fixed the fracture. The gap can open up when the phone gets hot again, or if you drop it again. Reflowing the solder connections can fix the root problem, closing up the micro-fractures permanently if done right.

Tou can try it again. If not works, you have to replace the motherboard or the wifi ic

Andrea Giannone -

After 6 weeks it stopped working again, even though I followed all the steps. The fridge method always worked maximum a few days so it is better then that.

I start to believe this is just another temporary heat gun solution, it is not actually re-balling or reflowing anything, it is just temporarily reactivating the messed up chip by heating its internals. Other reactions confirm that. I sincerely hope nobody is using this method to quote 'professionally repair' with 1 month warranty and charge for it, that would be a ripoff.

Joris - 回复

I wrote this guide for who wants to fix his phone at home. I repeat, this is not a permanent fix!

If after rhe rehot the wifi is still grayed out, you have to chiange the wifi ic. But is not simple to do this at home.

The mostly 4s after a rehot works forever. The same thing is for the lg g4 bootloop, rehot the emmc make the phone works again.

I usually offer 2 solution. X3 rehot for a small price, or i change rhe ic for the double price.. so the customer have this 2 option.

And they always prefer the first option...

Andrea Giannone -

Nono Andrea, the article says

"If this is the case, then the necessary permanent solution is to reflow the Murata SW SS1830010 Wi-Fi chip on the logic board."

So it is quoted as a permanent solution, so please dont say

"I repeat, this is not a permanent fix!"

After people spent a lot of time and money for tools on this article.

Joris -

Every time i open this guide, i see this message "This guide has more recent changes"

If you read my comments i always says that is not a permanet fix but can work for 2 days or 2 month or 2 years.

Anyway if someone spent time and money for buy the hot air station, he can spent also 10€ and buy the new wifi Ic and replace it.

But a 4s logic board cost 40-70€ so is stupid buy a new hot air station.

This is a solution for every user who wants to try to fix using a screwdrver and a hairdryer.. if this not work you have to bring the phone in a professional center who can fix it PERMANENTLY

Andrea Giannone -

WI-Fi problem is a HARDWARE ERROR. You cannot do anything on it. Upgrading makes more worse.

It begins when your phone gets heated. If you blow hot air on your iphone rear side just below the camera, it will reconnect the wire/register in wi-fi chip and your wi-fi issue will be rectified temporarily.

!&&* yeh! This procedure worked for my iphone 4s. The wifi setting has been greyed out since i accidently sat a bag of frozen peas on it for an hour. I heated the wifi chip with an ozito heat gun, with a small stainless cone on the front that i made to direct the hot air out of a hole about the size of the chip. Used a digital kitchen thermometer to monitor the temp at the chip was held around 200 deg C for about 5 min. Covered the rest of the board with baking paper layered under aluminium foil as someone else mentioned. Thanks heaps, procedure needs to be done very carefully but DEFINATELY worth a shot.

Btw I hadn’t a hot air rework soldering station so I used my soldering station instead. I placed a metal piece on top of the chip with the tip of the iron on it to help diffusing the heat to the entire chip and it mades the trick. A bit messy though but when you have no choice… :)

Hi, It seemed all solutions to this wifi issue focused on the hardware trouble. But I think correcting the hardware is just half of the way that is why in time the problem recur.

I’m not really sure, but I’m thinking the many IOS updates really heat up the phone, with later updates demanding too much on the design, like overclocking the chips.

Is there a way we could return/use the original IOS version or the latest which worked perfectly well before this issue on the wifi.
