    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. This is due to the JIS bits "thinner" design to prevent camming out of the slot. Otherwise everything went well. Looking forward to replacing the battery in my other phone that has the pentalobe screws. Glad I got the 54 Bit kit!

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

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

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

    chezbuttons - Ответить

    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.

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

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

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

    Before inserting the battery I put the contact clip into position. It has a hooked shape on one side which fits between the socket and the folded battery cable. If you try to position it AFTER the battery is installed the whole process is much more difficult. I used a tweezers to hold it in place while inserting the battery.

    misc - Ответить

    When inserting the battery I started by guiding the folded cable into position against the side of the contact clip, then proceeded to lay the battery in position. This made it very easy to have all parts in their original positions -- no need to fiddle with the battery cable or contact clip afterwards.

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

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

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

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

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

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

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

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

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

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

    Perhaps practice on some other things first.

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

    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.

    There is a washer under the plate that is held together by the 1.4mm Philips. This might come loose. Be careful not to lose it.

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

    marcx77 -

    So that small washer behind the 1.4 screw became detached during reassembly. What affect does this have? My phOne started to overheat; I then turned off my wifi and things are fine.. How is this related you think?

    On my phone the "washer" that the 1.4mm screw goes into I think is actually the mounting post that had come detached. I realize afterwards there was therefore no point removing this screw, but I did remove (and put it back afterwards) by holding onto the loose post/washer with tweezers to prevent it turning.

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

    tdroz - Ответить

    I found that the 1.4 mm screw measured a little less than 1.1 mm on my phone. So don't be confused by that.

    Daniel - Ответить

    When I came to reassemble at this step, I noticed the 1.4mm screw no longer had anything to screw to. The nut or washer or whatever it is that you mention has gone. My screen does not work any more. Is this connected and/or is there anything I can do to peplace what is lost?

    Chris - Ответить

    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.

    Christophe De Wolf -

    I didn't see that small "nut" and the 1.4mm screw is loose. So I didn't install it back. My iPhone is working now but wondering any thing would turn wrong later...

    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 - Ответить

    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.

    It seems that you misunderstood the notes throughout the guide. You should only clean metal to metal contact points, such as the contact area between the EMI fingers and the metal case on the speaker enclosure.

    If you are replacing any of the cables that connect here, be sure to save the foam from the top of the connector to put on your replacement part. It helps secure the connector once the connector cover is put back during reassembly.

    When reassembling, the various connectors have a leading plastic lip that allows you to align and then slowly snap in place. i pushed on the pads on top of the connectors with the flat tool provided in the kit.

    I ran into a not workin front camera after a screen replacement on Iphone4. I found out that I had broken the tiny jumper on the main board when I pried off the headphone plug. That jumper is next to the right upper corner of the headphone/volume button plug (yellow marked in step 17 of relacement guide), you can see it in the picture as two silvery dots. If your prying tool sits on that jumper when levelling the plug off, it is history. I took a ampoule of conducting silver liquid, but instead of shaking it I took some of the sediment out with a thin wire and aplied a tiny blob over the two remaining soldering pads left. And alas, it worked ! Front camera is ok again. Thanks to those who found out about that jumper.

    On reassembly, be really careful when reattaching the digitizer cable - the cable breaks very easily, rendering your nice new display useless. In my case, I must not have threaded the cable through properly, so it was just a bit too short to reach the connector. I gave it a gentle tug... and snap!

    I was much more careful the second time through :(

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

    Feeding those ribbon cables through the frame is one of the trickier parts of this repair. Check Step 30 of the Display Assembly Replacement Guide for detailed instructions. If you check the comments, you'll find a lot of others have struggled with this—but it can be done! :)

    Jeff Suovanen -

    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.

    Austin - Ответить

    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!

    This was a very tricky part. Just make sure that you don't put pressure on the login board to get it into place, take your time and ease it in.

    This was absolutely the hardest part - had to do it over many times. The digitizer ribbon cable kept insisting on folding up under the logic board. Tip: do not let the cable fold up, even it that's how it naturally wants to go, it will be too short.

scissorgirlsteph - Ответить

After doing a screen replacement my WiFi range went down to about 12 feet, and Bluetooth connectivity was inexistant. Taking out the logic board I had lost the tiny rubber protection at the top end, and replaced it with a piece of rubber which was too thick. As a result the tiny golden hook did not quite touch the steel frame, which is acting as part of the WiFi, BT and GPS antenna. Having removed my improvised protection strip and replaced it with a thin layer of glue, bent the gold connector out a bit, and re-installed the logicboard 0.5mm further up, I've got back WiFi connection to a mast 500 m away. So it's not just important to screw in tightly the long top screw of the black WiFi Antenna/EMI shield, make sure the little gold hook of the logicboard is in good contact with the steel frame too. I cleaned the steel frame with Isopropyl alcohol too.
