    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.

    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.

    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.

Believe me it saves a lot of time and hassle especially if you drop one of those tiny screws good luck finding it but when your working over the magnet and drop a screw its going to be right where it fell. At first I tried the piece of paper to keep organised but all it takes is one small slip and you move the paper too quick and your left with a jumbled bunch of screws and parts and a painstaking task of putting it all back correctly, aka a big waist of time and effort.

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

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

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

    The ribbon cable attaching the new battery to the battery connector clip is longer than the original.

One kink in this could sever the battery leads.

    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!

    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.

    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.

    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.

    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.

    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.

    Chris - 回复

    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 - 回复

    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.

If your prying tool sits on that jumper when levelling the plug off, it is history.

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.

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.

    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!

    Referring to the exact screw that is circled in red, I cannot seem to get this particular screw to thread properly during the reassemble process. I have found that I had to add another 15-20 min to my assembly/dis-assembly due to the fact I have to remove the earphone jack and the antenna that is in this corner, too. Any suggestions on how to get this screw to thread w/o doing the extra steps? Need of help, Please

    If your objective is to remove the front panel only, you do not need to remove any of the "large-headed" 1.5 mm Phillips screws, but only loosen them slightly. Putting these screws back can be quite a hassle, and there's really no need for it. When replacing the front panel, take care of the position of the washers (they should be in between the case and screw head.

    i tried using the 'only loosen' method on half, and found out because of the washers, they interfered during reassembly. it was very easy to replace them by setting the phone down on its side (propped up so as not to tip) and use a tweezer to put in the washer then screws, it was simple.

    I also used very fine tweezers (from a swiss army knife) to hold the washer and screw from the side as I positioned the screw over the hole, and then placed carefully the screwdriver tip onto the screw before releasing. worked fine.

    My screw here turned out to be rusted, so was REALLY tough to remove, I pretty much stripped it whilst getting it out with a 1.0 flathead. Not sure if this area is prone to getting wet, but be warned. I noticed an orange tinge to the screw before I started but thought it was a reflection from the ribbon.

    Dave - 回复

    This screw was also extremely rusty on my unit - so much so that it never came loose. I tried every angle and position but it just kept stripping out the Phillips head. Needless to say, I didn't actually get the home button replaced, because I could never get the screen off. But by doing all the steps up until this, I was able to get everything loose enough to check the home button connections, clean stuff up, wiggle things around a little, and get said button working properly again.

    But yeah, apparently this area IS prone to water/rust. I know my iPhone's gotten wet-ish before, so I guess it made it in here enough to rust out the screw. As Dave said, ye be warned.

    Since my screen was shattered, let's face it which is the main reason to replace the screen, it completely came apart around the button. Use of a hair dryer would have been a useful tip, however I don't blow dry my hair and so don't have one. A warm towel just doesn't cut it.

    The square piece your are referring to is the rubber piece that fits on the logic board. It seats on the logic board between the orange circled screw and the green circled screw in step 13. To date, I had one fall off during my third IPhone 4 screen repair. Needles to say, I had to part the entire phone out due to one stripped screw in the corner that was holding on the bracket to the screen. Luckily the screen and LCD was already missing and all that was left was the backlight.

    aggiphixit - 回复

    My screen wouldn't budge, nothing I tried couldn't get the plastic spudger started, even having the whole phone heated to loosen the adhesive. The way I worked it through was to *gently* push a small (2-3 cm) blade around the power button into the edge between the screen bezel and the steel frame. The hard steel blade started a small crevice, then I could work my way around with the plastic tool as described.

    Hope that helps if your screen is as stuck as mine.

    Be very, very careful when removing a broken screen. My experience was that while most of the broken screen came off, there were many smaller pieces which were stuck to the area around the home button as well as the camera lens. I took my time and used narrow-headed tweezers to remove countless shards of glass. Likewise, I found what I think was an adhesive membrane which I think was supposed to come off with the front screen but remained stuck to the frame. After some head-scratching on my part, I removed the adhesive membrane (tape) and hoped I wasn't removing something important. Thankfully, once reassembled, the phone worked fine!

    If you do have to replace the Camera Ring, I find it much easier to put some double sided 3m on the Display where the ring would go, then put the ring ON the camera, not the display.

    This part was very tricky because you need to make sure you have enough slack from the LCD and Digitizer cables. Take your time to make sure that the cables are fully through, even the slightest pinch will be enough for this to not reach and you have to redo it again (a massive pain if you've already started the reassembly. - A good way to test this is to before you reassemble try placing the logic board on top where the LCD and Digitizer cables will fit into, if they reach fine then you are good, if not then adjust the cables again until you know they are through completely, this saves you having to disassemble again if its not correct. - Good Luck and Take your time!

You do not need an adhesive. The combination of the existing adhesive (double sided 3M tape), and the screws that lock it in place are more than enough.

Dave - 回复

I was able to replace the LCD panel and digitizer as separate units, but they were separate to start with. That being said, it's definitely more challenging. it's pretty easy to get the two attached to each other, just takes 2 drops (1/10th of one ml) of clear oil. i used a 1/2cc syringe to spread a thin line down the center. came out absolutely perfect. without the oil it's horrible. No contrast and just moiré galore.

The added difficulty comes from getting the two parts to behave while assembling, since they aren't glued, they slip and slide around, and air can get in on the edges and no more dark black.

i tried first with water; terrible results, it interfered with the capacitive touch; ouch. So, i got some practice today re-assembling the phone. the guide was priceless—this is one of the most complex teardowns of ever. i used 12 compartments of an 18-comartment bin.

Great guide! I recommend adding some of the notes in this guide to the guide itself. One regarding the connector that goes under the EMI shield at the top of phone connecting the long screw at the top in the center to the gold dot on the logic board (I found this one in the notes OK). It is the connector for the WIFI and Bluetooth antenna as it turns out (the guide is incorrect as the antenna connector by the speakers is for the 3G/IPhone radio not the WIFI). The other, the rubber guard that fits over the edge of the logic board where the Digitizer and LCD ribbon cables bend over the logic board (I missed this step in the notes, but am not going to disassemble to fix, hope it's not too important, lol). A couple of more panels with photos illustrating the two steps would do it.

I could not have attempted this without this guide let alone be successful, great job! Thank you!

After installing the new display, the home-button is a little deeper immeresd in the display than before. As if the new display did not fit completeley inside the steel frame. When I look at the iphoen from the side - its also obvious that the glass above the steel frame is thicker than the glass on the back of the phone. could the new display (purchased from ifixit) be thicker than the old? I really tried hard to push the new display all the way into the steel frame and alle the screws attaching the display to the frame fitted in nicely.

Btw - the phone works fine and there is no visible gap between the new display and the steel frame.

Great instructions and pictures. I would add that the 2 cables that slide through from the screen/digitizer should be tested for connection and actually connected BEFORE tightening down all corner and side screws to ensure you have pulled them through far enough.

Im cheap tip #288

use 1oz "solo" cups to put your screws, clips, etc in. The First cup shoud contain the first two screws from the bottom, then stack an empty cup on top, next would be the screw from the battery connector. was rinse repeat. you get the idea. when reassembly time comes around, you would be suprised on how fast things go back together. no second guessing.

Just replaced the front display and rear glass on my Iphone4. I had one problem, but I think it was due to a manufacturing defect or an error during the assembly process at the factory. The headphone jack/volume control ribbon cable was covering most of the slot where the thin metal cover retaining clip resides. I didn't notice it during the disassembly process, but when I started to reassemble the thin metal cover, I noticed the ribbon was covering most of the slot and had an indention on it where the retaining clip had deformed it a little. The ribbon was covering all but an 1/8 inch of the slot where the retaining clip should fit. I had to file all but 1/8 inch of the clip off for it to clear the ribbon.

I finished the reassembly process and ops checked the iPhone4. IT ALL WORKED AS ADVERTISED! WiFi, Bluetooth, email, texts, phone; the works.

Thanks to Ifixit, I was able to accomplish a task I never thought I could successfully undertake.

This worked like a charm, but I learned a few things that I would like to pass on. This takes more than an hour if you have large hands or your screwdriver isnt magnetic enough to pick up the very small screws. Also, there are numerous sizes of screws, so when you disassemble, lay them out in order they were taken apart. The guide ends and then you just need to look at it in reverse to reassemble, but take care in remembering how to replace some of the parts - ie the shields. Also, make sure you have all the required tools. Another thing to remember is that the you need to make sure you pull the cables all the way through when you put the new screen on, otherwise you will have to remove the motherboard again and start over. THanks iFixit!

I attempted to replace a broken front screen and failed miserably and I will pass on what I learned from it. I can identify several reasons as follows: 1) I was not fully prepared mentally to undertake such a tedious task. I should have anticipated more time and started when I was alert and fully motivated. Instead, I started at the end of the evening when I was fatigued from the day.2) The lighting was an issue. This seems basic but yet I overlooked in my anxiety to get started. And, 3) The screw drivers I was using were poor quality. I seemed to strip about 50% of the screws. Since then. I purchased better tools and have not had this problem.
