iPhone 4S的前置摄像头更换

my screws are stipped and i am going though the front glass to get to the logic board could some one give me a guide on how to get to the board please... thanks

all you need to do is remove the clip over the wifi antenna and the one that actually attaches the wifi antenna to the iphone two steps to do this job...

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. I also found using the Liberty Kit to replace the pentalobe screws was worthwhile.

Poor old Marv of Feb 2015. Suggest he sticks to chopping logs.

If you are careful, use a Dremel tool and a micro drill bit (sold where Dremel tools are purchased) to drill it out. Last resort kind of thing, good luck.

Why isn't it moving? I removed my screws.

I pried one end of the back off only to find 2 funny little screws holding the other end on so I took my Dremel, like Jack said, and ground those suckers out. Once I had the back off I loosened all the screws then turned it upside down and shook the crap out of it. The screws went flying everywhere and fell on the floor. Its my moms house so of course she's got gross brown carpet. How am I supposed to find my screws in that? I get the vacuum out and go over every inch of the floor to suck up all them screws. Then I dump the bag on the table and all I find is a bunch of hair and gods knows what else, but no screws. When I look for my phone I see its covered in all that stuff that came out of the vacuum. I mean, what's up with that? How can I work on my phone if its covered in dirt? Nobody said anything about that, did they? The average guy's gonna screw up his phone big time if he follows these instructions and nobody warns him about all the dirt that's gonna end up in his phone. Are you kidding me!! Now what?

I didn't see any extra screws holding the back in place. I had to use the included pry tool to get the back off. Just start at the bottom and pry gently...if you just "pull" like the guide says it won't work.

Don't use too much force to slide the back -- the back on my phone was hard to slide, and I bent and broke a silver metal contact tab at the top of the back (on the inside).

Super easy fix. Thanks for the tutorial!

Those little screwdrivers are easy to mix up, for those of us without ultra-perfect vision! Once I used the correct screwdriver, and my 13yo son's little fingers and perfect eyes, it went smoothly! Also my son noticed that the rubber piece around the camera len was covering the camera; it likely slid out of place when sliding off the back cover. A little playing around (with plastic tools only!) and it looks perfect now!

sorry but the rear panel is not pushed up. I pulled out the screws in the step 1 but still the rear panel does not move with even when I push it strongly.

On reassembly, be sure to clean the metal plate at the place of contact with the tiny pressure contact mentioned in step 4.

I pried one end of the back off only to find 2 funny little screws holding the other end on so I took my Dremel, like Jack said, and ground those suckers out. Once I had the back off I loosened all the screws then turned it upside down and shook the crap out of it. The screws went flying everywhere and fell on the floor.

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.

From this point go to step ?? Just peel off the tape from the chip. Take some aluminium foil and cut a hole the size of the chip (Use a second layer of foil if you don't thrust it). Heat the chip as described at temperature 300 deg C for 5 minutes. Let it cool down. Reassemble and ..... hura WIFI is on again.

I also had a small black and gold connector held down by the top screw on this step.

While the text refers to the pressure contact, the pictures do not show it clearly. The closet one that does has the yellow circle covering much of it. I was not sure if it was under or on top of the cover when re-installing. It's under.

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.

Which screwdriver works best then. I got the #00 philips from ifixit. I agree - it strips the screw and does not work. I don't recommend it.

I am now trying to buy another screwdriver - but which one. #0 or #000. Anyone done this. Please help!

I lost the screws securing the battery connector to the logic board, what happens when I turn on my iphone without securing screws, as shown in step 4, please solution. thank you

I completed this successfully, but this step gave me the most trouble. The pressure contact is really difficult to reseat. So much so that it should probably be called out more clearly in it's own step.

When reinstalling the position of pressure contact must be explained better! It took me about 5 min to understand how it fit!

In french: attention avant de retirer le contacteur de la batterie. La vis du haut tient "en sandwich" une petite pièce métallique noire et dorée. Cette pièce a pour but de faire contact de masse avec le dos de l'iphone quand il est refermé. Donc il ne faut pas la tordre. 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.

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.

Pressure contact needs to be remain EXACTLY in the same position if you remove/replace battery. I had to re-open my iPhone 4S after a battery replacement (the mobile connectivity was lost) and tweak the position of the Pressure to restore functionality.

Why do I have to remove the battery for disassembling the rear camera? Any idea?

Hi, I have a problem with that small piece which connect gsm antenna with the back cover. I missed that part and have a weak signal gsm, so I buy it and now when I put it there the Iphone wont turn on when the back cover is puted on. I know that somewhere is short-circuit but dont know how to solve it. Sorry for my english.

I used my 16x magnifier loupe to be certain I had the pressure sensor aligned with the screw hole - no problem, no stripping. I consider it indispensable for tricky steps like this, and IFixit sells a similar tool for just $14.

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 bronze and black thing is the ground, *not* the pressure connector. If you remove it just keep track of it and re-install it.

this help me a lot, i just don't know how to fix it(bought it from http://www.laimarket.com/red-replacement...)

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!

There's only one Philips screwdriver with the kit but it failed to unscrew the top 1.7mm one off the connector unfortunately. Is the kit supposed to come with both the 1.7 and 1.5mm Philips screwdrivers?

When disconnecting the battery make sure to use a plastic tool not a metal tool that could short out the battery

I did not manage to get the screws out with a Phillips #000 Screwdriver; I used instead the J1000 head of the all-new pro tech toolkit

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.

When i replaced my battery then my i phone4s suddenly diseabled to 4million hours or sonething big like that....So at the end i had to go for a flash..when it was updating in the middle there has been a error so my logo comes CONNECT TO ITUNES...so what can i do guzs????

Vous dites "Le connecteur de batterie s'enlève verticalement de la carte mère. Ne forcez pas latéralement"

Ou placez vous la verticalité ? pour moi c'est connecteur d'alimentation en bas, bouton d'alimentation en haut ?

Parce ce que sur la photo suivante, vous enlevez le connecteur de la gauche vers la droite ... c'est à dire latéralement ...

Soit nous n'avons pas le même sens vertical / horizontal, soit il y a un GROS problème dans l'explication, ou dans la traduction.

En tout cas, à la lecture de votre explication, j'ai essayé d'enlever le connecteur vers le haut !!

Donc il m'est maintenant impossible de remettre la batterie neuve, le connecteur est cassé !!!

Bravo pour l'expertise ifixit :(

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-...

Why the guide don't mention PH000 or PH00 instead of Phillip 1.7 mm / 1.5 mm? I didn't know it is PH000 until some comments here save my time. Thanks guys

We have edited this step and expanded upon it. Hopefully that will mitigate the confusion surrounding it. Sorry about all the trouble it has caused!

This picture needs to be greatly enlarged! The pressure plate sits directly underneath the battery connector, but cannot be seen here. It is also flat but about half the size of the battery connector, so you won't know you've ripped it up until you have! Picture two slices of bread but not the same size, stuck together.

What if you pop off that pressure contact point?? What is its function? Is it impossible to re-attach?

I also accidentally removed the pressure contact. I put it back in place as best I could during reassembly and so far haven't ran into any problems.

The black & copper contact piece is missing from my iPhone. Does that explain why my phone won't restore and keeps re-booting? I have tried every kind of restore with no luck. Any ideas?

Very good tutorial,

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.

This is a hard step because the directions and pictures are not very clear. This might help:

1) Here you HAVE TO disconnect the battery connecter (the language is confusing).

2) This is easier than it looks, as you can simply lift the connector upwards from any angle (I rested my plastic tool on the antenna and gently lifted it up).

The photo suggests you have to pull the connector backwards (which would be hard), this is not true, it can be lifted up towards you (the pins go out backwards and upwards, you'll see).

Finally, don't confuse the "pressure contact" with the "pressure contact point". You remove the contact, the contact point (underneath) sits on the board. No need to worry about this.

Very ambiguous instructions for amateurs like me. eg. "pressure contact" & "pressure contact point". Some labelling in the photos would be a great help.

Wish the instructions had the warnings about the pressure contact before getting started. I removed it from the logic board because the warning was after the instructions. I managed to get it back in place and reassemble the phone. Nothing happened when I turned it on. Here I wrongly assumed the battery came pre-charged but it wasn't. I decided to plug it in to recharge it and was elated to see the empty battery symbol. I'm sending this from the phone!

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.

After reassembly, the CELL CONNECTION WASN'T WORKING. You might need to slightly bend the contact in step 5 up just a little, so it will make contact with the metal back plate. Did that and it worked perfectly.

Great kit, great instructions, thanks!

all those teeny screws...and the world is so...well...BIG!

go slow and put those parts INTO something...

putting them "on" something will just cause heartache and and an infected bladder...

°¿°

after a lot of froofroo and very errant iphone behaviour problems, i concluded that that tiny grounding piece must be being lazy as hello. i spread it out a bit to ensure a better contact with the back plate and everything appears to be working smoothly.

did this repair, as well as the battery replacement...GTG!!!

spoke too soon, i 'spect...random reboots persist.

Just went through the replacement and the battery "plug" (step 5) on my replacement battery was slightly misaligned relative to the metal plate used to screw it onto the board. 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.

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.

I accidentally removed the pressure contact and I was not able to put it back in place and so far haven't ran into any problems. Is this safe??

I did it als well. All Funktionen well.but i am Not sure if that reduce battery power? Thanks very much for information

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

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.

We have edited this step and expanded upon it. Hopefully that will mitigate the confusion surrounding it. Sorry about all the trouble it has caused!

This can be very tricky because sometimes theres just too many glue on the back of the battery, and eventually the battery will be deformed.

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.

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...)

Removing the battery wasn't necessary. I attempted the removal but decided not to in the end. It didn't get in the way at all.

I did not remove the battery to do a Speaker replacement and had no issues with getting the Speaker out/in. So, steps 4 and 5 are required but not step 6.

The plastic tab is not attached to the battery. I just pried from the right and slid tools under until I broke all the adhesive.

I found it easier to start by pulling the plastic lip to loosen the battery, then, if needed, use the plastic tool to pry from the side.

I tried to get the battery out as depicted in the first picture. It deformed and is now broken. Not happy. It seems better to leave it or get it out by gently pulling the tab.

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.

Be VERY careful NOT to pull off the part of the connector that is on the logic board! Mine now has only contact but no solder until I can get a small enough soldering iron and a less shaky pair of hands!

I bent the wire of the silent button on right top of the battery. Now the silent botton don't work. The wire on the bent is half-cut. BE CAREFUL when you put the new battery inside!

Was having a hard time getting the screws back into the battery connector. Read another tip online that helped - pushed the end of my phillips screwdriver into some soft candle wax which gave it just enough stickyness to have the screw stay attached to the screwdriver while I was moving it toward the hole. Thought I'd pass that along.

I did as wazzamagu did (and stated above), "My Pentalobe tool was slightly magnetized so I used that to bring the screws in for tightening with the Philips screwdriver." That made replacing the screws fairly easy. Thanks for all the advice on this page. It was not hard at all. Go slow and carefully, everything is smaller in there than I expected. The "searching" thing came up as it seems for most people, but just took a reboot and all is fine.

Instructions were good and everything works fine after replacement. Needed to use a tweezer on the pressure contact on the top screw of the battery. Thanks

I swapped out the battery today. No real issues. Pretty easy task.

For the past couple of months, my phone had been dying very fast. I knew that my phone's battery capacity was getting quite low as this phone is older now, and is out of warranty. So I ordered a replacement battery about a week ago, and just installed it yesterday. The install was pretty easy, if you pay attention to where everything belongs. But my draining issue has not gone away. It stays charged a bit longer, my capacity is at almost 100%, yet it can't even hold a charge over night. I'm not sure what is causing this and would love any tips or stories from someone else!! Please help!!

Beim Einbauen des neuen Akkus ist es sinnvoll diesen zuerst anzuschließen und dann erst wieder in die richtige Position zu bringen da man so dass Anschlusskabel besser verlegen kann

OMG thank you iFIXIT, the apple store wanted 3 times the cost of this repair kit. It took less than 5 minutes with most of the time spent trying to prise out the battery as it was glued in nice and tight but steady pressure from the spudger did the trick.

I think the best advice would be to touch nothing with your fingers as with careful use of the spudger I was able to position the tensioner point no problem. Everything else was nice 'n' easy.

Finally there was no cell connection only Wifi when I powered up so I simply powered down and up again and all is well in the world!

Thanks again.

Be VERY careful not to pull on the plastic tab before you fully detach the adhesive or else you will rip the tab clean off. If you did this it is still possible to remove the battery. I just used the guitar pick tool things to slowly work it through the adhesive and under the battery

It is possible to remove and replace the upper antenna WITHOUT removing the logic board!! So skip from step 7 to step 21 to 26 and 27.

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.

Watched the video and ordered the kit, followed all the steps and it all went brilliantly - thank you all so much.

Is it suggested that I add more adhesive with the replacement battery?

One thing I noted with the replacement battery - from AussieBattery here in Australia; not from iFixit - but the same problem might occur; is that the cable on the new battery had to be 'tamed' (bent here & there like on the old battery, before I could reseat the screws and even the battery itself. One again the black - pointy & flat ended - spudgers, that we use in desktop iMacs, were helpful in getting under that battery and releasing it from sticky-!&&*! I used a pair of '2.5' reading glasses for this job, but '3.0' might have been better, as those screws are INFINITESIMALLY small!!!!! :(

Thank you IFIXIT! The battery replacement went very well for me. I was exceedingly careful with the minuscule fasteners. Reading through the instructions, watching the video and reading these comments before jumping in helped. I found the parts and tools to be of good quality. I feel like I beat the system! I used a pair of diopter 3 reading glasses which was a real aid. I hope my comment encourages others...

My rare earth magnets came in handy when I managed to lose the little grounding connecter screws. Those little guys will go flying if, while trying to align them for reassembly, pressure gets applied in just the wrong way. I say one fly out and bounce off my shirt, then it was gone, on the floor I presume. I grabbed my stack of 8 little magnets, waved it around on the floor under where I was sitting and what do you know? A little screw was stuck to it! I never would've found it just by looking...

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. I had to look elsewhere for videos outside of iFixit to figure this out. Also, tell us which screwdriver to use using the label on the bit (PH000, P2, Y000, etc.). Providing only the sizes of the screws does nothing to help determine the appropriate bit to use when they aren’t labeled as such. Otherwise thank you!

I replaced the battery and the phone started right up. But I cannot get it to charge It was half charged when it went in new and I plugged it into a charger Checked it later - not charged. So tried another charger and the green charging light still will not come on . Any suggestions? Thanks Don

I succeeded to replace the screen, but I made a mistake with the batterie cable, and it finally broke, seems that the cable was too long and I was forced to make too tight loop.

Maybe a series of photo to explain how to make this the right way.

Are the screw sizes switche up by any chance? A 4S i have here has the left hole bigger and one of the screws didn't want to go into the right hole when it went nicely into the left one.

Fabulous tutorial! Many thanks! i have now a working iPhone back after display crash and glass brake!

In Step 8 I think the colors of the screws are inverted. The larger screw is at the left (near the sideboard) and the smaller is in the middle, near the battery (iPhone 4S).

Was trying to fix guide but accidently messed some things up in formatting and I too also believe the picture is incorrectly displaying the 1.5mm(which is the left screw) and the 1.2mm(which is the right screw.

I believe the guide is correct, but be careful as the screws are not the same as the other 1.2mm screws from later on. Length is the same, but the diameter is not... just keep them all separate.

Organizer: tape cheap duct tape tacky side up to a tray. Get a ball point or roller ball pen. For every screw, write step number and a letter for color (R, O, Y, etc.) then stick the screw there. I bumped the table and nothing moved. Also use a big white towel as a work surface: nothing bounces away if you drop it. This helped re-assembly

Also remove 4 screws holding metal cover plate adjacent to camera lens, remove plate to expose camera plug. when removing the rear facing camera, be careful not to loose the small grounding finger mentioned in step 21

Same for me as for various other posters here: the bigger screw goes on the left, the smaller on the right. Doesn’t fit the other way.

My gold adhesive has torn, exposing a sliver of the flat wire beneath it. I have put a bit of insulation tape to prevent any contact between the wire and the top of the vibrator and metal piece on the logic board. I don't know if this is sensible or not. Depends whether the gold adhesive is intended to be an electrical contact with these bits, or an insulator from these bits! I will post to update once the phone is powered up / blown up!

Ok, I did all the steps and phone seems to be OK, wifi is actually working again, yaaay.

But cellular connection is messed up. It will have full reception (5 pins) for about 10 seconds, then drop to 1 pin for a couple seconds, then go into "searching" mode. After a few seconds in "searching" mode it will go back to full reception and the process repeats itself in a timely fashion, over and over again. Obviously I messed up somewhere but where? Which connections are faulty/beyond repair?

I dismantled the phone again and concluded that the digitizer cable was kind of loose (don't know if that affected anything, but i put it down firmly this time). I had 2 problems, the cellular connection I mentioned plus the phone would charge to 3 percent, die, and then repeat the procedure. 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. The cellular antenna connector I pushed down firmly to make sure it was connected, I was gentler the first time, now everything works.

Sometimes found stuck to the inside of the back cover.

Don't do it!!! you can skip that, it will stay and its more of a pain to remove it.

This is unnecessary step!! Don't do that!!

Agreed, mine was stuck inside of the back cover

So was mine - thanks for telling! Rests of soft glue could be scratched off the place - so the ring was already off and I looked for it everywhere.

Mine was stuck to the cover too, thanks for posting.

Mine too, thx :)

The fastening on the board came loose when trying to remove screw the 1.2 mm Phillips screw. So the screw hole for that screw is still attached to the cover that I removed.

Got to step 13 and could not remove the 1.3mm screw (yellow circle), even using a different Phillips head screwdriver than the one that came with the kit. So frustrating. Was able to remove the other screws leading up to this point without difficulty (used the saran wrap trick on the other screws to prevent stripping, but this 1.3mm screw just would not budge).

Ended up abandoning the screen replacement--luckily the phone works after putting it back together.

In my case, the 1.3 screw (yellow) wouldn't tighten on reassembly. I might have tightened too much so that it stripped the screw hole. Anyone know whether this has damaged the board in some way. The phone works fine, but concerned about the long run.

If you just very slightly twist this plate clockwise as you are lifting it out, it will help as there is a little hooked piece at the lower edge on the very far right. You have to be careful not to turn it too much though because this hooked piece is right beside a ribbon that could be damaged.

To add to Trisch's comment:

If turn the plate clockwise doesn't do the trick, the hooked piece on the lower right comes off when you pull the plate towards you a tiny bit. Still, watch out not breaking that ribbon the hooked piece is behind of.

If you're having trouble removing the EMF shield, try using a plastic prying tool to lift the top right part while pushing it ever so slightly downwards with a finger. Consult this video for details: https://youtu.be/8fujLMaxJsw?t=6m42s

Im pretty sure that when you reinsert the cam the grounding clip has go to between metal sticker and the cam body, or the camra wont be grounded

I've got a trouble at this step. Is there anybody who could help me out with my problem? When I was removing the camera module, accidently removed small element, which is marked with the red line http://i63.fastpic.ru/big/2014/1022/4e/9...

As I figured out - that is the SMD capacitor. After that Iphone was switched on, and it seems to be working fine at the moment, but I am very scared, if it will continue to work well without that small piece. Anybody to help?

In my case, the grounding clip was taped to the camera! In addition, my repair process stopped at this step as the left screw on the power button had come out and was floating around next to the camera slightly stuck to the tape. This was lucky since a loose screw in an iPhone under the logic board would be a bad omen.

I agree that the SIM card should be removed before you even start. After I completed this repair (waiting until this step to remove the SIM), the SIM card and holders won't go flush with the side of the phone anymore. The phone still works and everything else is fine, it's just annoying that I have a SIM holder sticking out about 1mm. I'm not certain this step caused this, but I'm just letting folks know that I agree with jmaelzer.

To be honest, it's really hard to remove SIM card without a correct tool.

Is there any reason why you still have the ribbon cable under the little metalic plate (right under the sticker that says "Authorized Service Provider Only") plugged in in STEP 10. And it is without any instruction step removed in STEP 12? I mean it's not like it is complicated, but when I got to that part I was confused there for a minute that I forgot some step, and then reassured myself that I did everything as it said in the manual.

I have done everything correctly but when i turn the phone on all i get is a blank screen. The phone operates as normal i.e. it rings, vibrates etc but the screen is just blank so you can't actually do anything with it :(

anyone had the same issue?

FWIW, I found it easier to replace during re-assembly by turning the phone front-side up, as on the Sprint-locked one I was working on, the SIM card faces that way. Otherwise, it tends to fall out (down) while trying to re-insert it if the phone is face down.

Popped the SIM card holder out no prob - but there’s no SIM card. This is a Virgin Mobile phone, does that matter?

Need to remove the shield over the connectors first. Look at the other guides for the 4S they show the 4 screws and how to lift the shield out, take out the camera etc.

During reassembly, I noticed that the data display cable is rather stiff. It may be a bit tricky to get it reconnected, but you'll know once it's in.

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 ripped the power button cable(didn't see it), any chance it could be outlined with a dotted color in the future? (I'm bad at reading the warnings)

It was a lot easier for me to use a fingernail to remove these cables. It provides a lot less force, and is more likely to remove the cables without damaging them as they are very easy to break.

During reassembly, note that this small 1.5 mm screw goes into a thread in the head of the larger 4.8 mm standoff screw near the headphone jack.

(be careful but gently forceful; the part doesn't come out without effort)

Prying this off took the most effort as it's a squarish 'C' clip with two small 'teeth' like points that grip the bottom.

You can use the edge of a plastic opening tool to easily lift the other side of the grounding clip.

I used a metal spudger from the Pro Tech Toolkit to remove the standoff, seemed to work better for me than a flathead screwdriver.

The flathead screwdriver provided is much too small to remove this piece!

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.

Not all screwdrivers are equal. I took mine in the shop and ground the blade thinner then made sure the end was square and flat. You can do this with an emery board or sand paper. You want a good fit in the stand-offs.

Great Guide and thanks. Now...what if i snapped the wifi antenna cable together with its male connector from the board? Like tearing it apart ? Can this be replaced by any chance? Thanks!

I also had a problem with the connector breaking off, but after putting everything together, the WiFi seems to work like before, so I guess there is no problem there...

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. Because then logic board can move a bit when repositioning connector and to slide right place before connecting it properly.

Dimension given are Length of screw. I think it meant to say 2.6mm screw.

So, my 2.6 Philips screw near the power cable just spins and spins. It happened the first time, so I know I didn't strip it. Any ideas?

So, I couldn't gind the tape and instead of digging around. I did what no one should do. I twisted and pulled. So now the screw that holds the upper left corner on broke that part of the logic board off. Everything else went back great....Phone won't turn on. Am I screwed here?

step 13 - “One 1.3 mm Phillips screw”

step -22 “Notice the small rubber bumper under the screen & digitizer cables (which are detached at top above the Q-code)”

“Note that there is a rubber insulator that is loosely attached to the PBC that can be seen in the upper right corner of the red outline near the tag with Q5M on it”

now, the problem :-)

while assembly the iPhone I screw by mistake the 2.6 mm instead of the 1.3, and without noticing I break the 1.3 base screw from the motherboard :-/

Now, the rear camera is not working.

I couldn't figure in the picture above, if the rubber bumper you mean, is under that screw or above the Q5M tag ?

Can it be that the dewar camera don’t work because of that broken screw?

Any idea how to fix it?

Is there any option to buy the rubber bumper, if I lost it ?

Appreciate any help,

thanks!!

Under the screw is a ground clip from step 25. I tweezed it out here since it might bounce free while pulling logic board out. Use a big white towel as a work surface to prevent wayward bouncing bits from flying off the table.

Caution: the image with the QR code is "mirrored" --> look at it "reversed" !

If your driver is just spinning in this step, you may be trying to turn the offset screw instead of the phillips screw beneath the tape. The tape is not obvious, and I found tweezers helpful when removing it.

I used a metal spudger from the Pro Tech Toolkit to remove the standoff, seemed to work better for me than a flathead screwdriver.

The Kit Provided flat head screw driver didn't fit in the stand off screw heads on my IPhone 4s. I had to use it in only one side of the screw notch to slowly twist them out. Its doable but could use a larger flat head, but the blade needs to be micro thin.

I wound up stripping one of the screws on this step. Was frustrating but I found if I too a sharp knife and gently went back n forth I was able to make a little notch to use a flat head and got it off. Other than that all went well.

Found Logic Board Rubber Bumper Location?

hey, i removed the logic board and gave it a bit isopropanol spray. is this ok? how can i found out if it is working? is it possible to remove something from the logic board? thank you :)

Check this... Rubber Bumper Location =)

http://mac4mac.co.uk/viewtopic.php?f=2&t...

On reassembly, you are putting the plate under the spaghetti. I went back a few times to get all the cables out. Here is a check list before you tighten any logic board screws or try to jam the top edge of the board in place:

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.

Before logic board re assembly it is nice to use scotch tape ( temporarily) to bend all the connections above the battery compartment . Doing as such avoid to have the power button connection remaining below the logic board .

Apparently it had uncovered my iPhone before, because when I did not find this piece uncapped here. I need to know which function is on the iPhone and if it is very important. How could I get?

Hi, I had the phone apart to replace the wifi chip.

Has anyone found a source for the two nano sized SMD resistors, because this also causes "no wifi" syndrome due to them being important for the I2C lines.

thanks!!! -A email testing_h "at " yahoo.com

I removed this in step 22 even though it only slightly alluded to it. If you did, too, don't panic. Go find your step 22 parts and verify it is there. :)

I did it. No problems!!!

I used a Tupperware orange peeler as a plastic opening tool and didn't touched any screws oder other inner parts.

I had to do it two times, because my old 4S 64GB has a broken WLAN Chip on the logic board, and my wifes 4S has broken her display glass. So I took her logic board into my 4S body. Now we have one running iPhone 4S 64GB instead of two broken phones.

HELP! Miy clip does look different, and i have no idea how to fit it in

This little piece was missing when I opened my phone, seems it was lost last time I sent it to the repair shop for screen replacement.. :-( but it does take pictures

This is really hard to get out. I broke 2 plastic spudgers (cheap/free) trying this

it might be an idea to mention that the retainer has three tiny little clips that point outwards from the camera and while taking it off is hard, putting it back on is even harder

Step 26 cause me great pain as well. I couldn't get it loose with the plastic spudgers. I had to break out a tiny metal screwdriver. I was so paranoid that I was going to break the part or the clip. The trick is to get under the clip's "fingers" that fasten it on the sides. The issue is that even my small my plastic spudger was too big to fit in the available space. Ultimately I got it to work with a micro flathead screwdriver, but it wasn't without serious concern.

Using a micro flathead screwdriver did the trick. I found that prying from the top right corner worked best.

Yes, this is hard. It would be a lot easier if the guide had a picture of the retainer clip. I was successful with a spludger by lifting it on the upper left hand corner. Once you have it off, have a good look at it before putting it back on. Remember that it clips to the outside of the camera housing.

The clip has a hole and a groove. This is good enough to grab it with some pin tweezers from the top when replacing it.

I totally agree with Andrew, when changing the power and sensor cable, do not do this step. It is absolutely unnecessary and only increases the pain when reassembling your phone. That step should not be in the guide for the power cable replacement.

I agree with Andrew, this step is not needed.

If you are replacing the headphone jack, DO NOT DO THIS STEP! It's totally unnecessary.

Based on comments here, I skipped this step fixing the power button and it was fine, you have a little less room to remove the earpiece wrapped in the power cable but if the removal was as hard as people describe, it was easily worth it.

I could not reassemble the retainer. The legs would not go back to where they were meant to go and I badly bent one in the process. I replaced the retainer with a small dop of Blu-Tack ("a reusable putty-like pressure-sensitive adhesive"). This gets squashed down when you replace the logic board. This keeps the camera correctly positioned and works OK so far.

I think the key to getting this clip on is knowing that the fingers do not clip on the inside of the retainer, but slide over the top and the 'elbow' locks in the retainer openings. This makes it a ton easier.

There is no need to remove the front facing camera or power button/flex. At this point you can just remove the retainer clip over the sensor assembly, pry the sensor assembly from it's holder, bring it back over and clear of the earpiece speaker, carefully pry the speaker from the frame, replace the speaker with new one, reassemble.

Getting this off with a micro flat head is best - putting it back on you need to slightly flare out the little fingers on the side two (facing top and bottom of phone-just enough to make getting it back on easie. Then using ifixit flat tweezers you can get in and pinch the fingers closed again once it's on.

I quickly regretted not having read the comments to this step and the next one. When replacing the power/sensor cable, this step isn’t necessary, provided you are careful enough with the earpiece speaker and the sensors which are next to the front facing camera.

DO NOT DO THIS unless you are sure you have to. This step and the next one are not necessary when replacing the power and sensor cable.

It is very very difficult to fix the front camera retainer again after removing it.

I have no idea why this step is needed. I skipped over it and was successful at taking it apart

true, don't remove it
