iPhone4屏幕总成更换

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!

Use a vacuum duster and a sharp tool to pry out the dust, this can increase the volume insanely!

At the very last second before insertion, the second new screw for the bottom popped out of my pliers! I dont' want to use the old ones, but I don't want to leave it with one screw. Can I get a replacement screw?

Otherwise it went together fine, and I figured out for myselkf that the contact needs to be bent,,,

What does the park that is gold and next to the 4.8mm screw for the antenna? Looks like I am missing that part and almost positive that is why I can't pick up or connect to any wifi signals. I have the screw and the antenna from another phone that is working and tried it on the broken phone and still doesn't work. Only thing different is that gold metal piece to the left of that 4.8 mm screw. Can I buy that part? how do I attach it?

great instructions did it the first time

very informative i also visit http://itrepairguide.com/iphone-4-intern...

before this which is also too easy

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.

If the back doesn't slide in properly upon reassembly, you didn't insert the motherboard properly. Remove it and try it again, DO NOT try to force it down!

using suction cup with too much force breaks rear panel

don't use hot soldering iron . the female outlet the battery plugs into is very fragile . for no extra money you can buy a battery that has magnetic tools specifically to pick this screw out . if worse comes to worse be certain the screw will come no looser then use tweezers and pick it out . the #1 fear with this technique is DO NOT DROP THE SCREW . I have done this and crawling on my hands and knees till I find it was depressing

I have tried everything to remove the screw securing the battery connector to the logic board and nothing. Any help?

Use #000 fine screw driver!!!

Use an #000 fine screw driver to remove two screws from iPhone 4s!

There is a metal bracket that secures the connector, that will be removed before the conector is unfasten

When I used a plastic opening tool to gently disconnect the battery connector from its socket, I accidently remove the socket too.. Now what? :( ......

my phone doesnt have a screw that connects the battery to the logic bored...is that a problem?

I didn't need to remove the battery !! why would you take the battery away, the motor can be removed easily with the battery in place, and the whole process would take less than 2 minutes if you exclude the battery steps

I have trouble with the screw: I bought my used and now opened it for the first time. The screw is totally messed up, I can't unscrew it because the screwdriver doesn't fit in the screw/doesn't unscrew it. What can I do?

Installed new battery without a problem. Now it does not hold a charge for more than 4 hours. Phone works fine but what did I do wrong?

I was VERY careful but the interior philips screw holding the battery in place but it stripped immediately. I see others have had this problem. What do I do now?!

How can i get my battery out if the screw is broken?

always record your repair on a camera

I bought a Mmobiel branded replacement iphone 4 battery, but it doesn't fit – the pins on the connector are (very) slightly different in pitch to my original battery. Not sure if it's related to the fact that my original battery connector has two screws, and the replacement has one (like the photo in this guide).

There is a small black L-shaped bracket of some sort that tits between the battery connector and the motherboard socket, with a loop on one corner that sits betwen the riserand the battery connector. Remove this now, and do not forget to re install it on assembly.

When reattaching this bracket make sure your Battery ribbon is already tucked underneath the battery with only the minimum clearance required. Then make sure the brackets overhang is over the battery ribbon. Dont try to slide it under the Ribbon.

In Step 5 be EXTRA careful with the battery connector as the socket can come off extremely easy. This can mess up the replacement a little bit and cost you extra. Otherwise, this guide is excellent.

Good luck, fixers!

I fix(ed) it!

When removing this L shaped piece, it should be shown ON CAMERA where it came from and the exact position it was in while in the phone, I had to take 2 screws (not 1 like said in the video) out to get to this piece and once that second screw came up I didn't get a chance to see where this piece came from because it popped right out. I was extremely nervous but I believe I got it back in properly.

Putting the antennae cover back in place is impossible without a good photo. I used this link to refer to:

iPhone 4S Battery Replacement

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

In such an instance, you could use the iPod opening tool to assist (just be careful where you stick it!)

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

Understand that the plastic pull tab is part of the phone. It sits under the battery like a tray and is not connected to the battery so it needs to stay in tact.

once the iphone restarted, the battery was at 30%.

This i think is the most diffucult part.

Because they use so much glue on it. I have to did this with so much force.

Glad that i didn't kill the circuit board when i took this out.

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.

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

Non problem with reassembly - just took patience - my is that the phone now does not want to charge the battery. It shows taht the battery is dead and charger needs to be connected but does not charge?

What have I not done coreectly - or at least what can I check to determine the problem?

Thanks

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. Then used the plastic tool to gently but firmly pry up one place on each edge. At first it felt like barely anything was happening, but within a few tries the adhesive gave away easily and the battery came right out.

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.

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!!

Battery is in, phone fires up, charger works. This is the first 10 minute job I've ever completed in 10 minutes, thank you!

Why they didn't say this, I have no idea: HEAT UP THE BACK OF THE PHONE! This helps the adhesive give so much easier, worth the extra 2 minutes to make sure you don't tear anything.

super easy, battery had plenty of glue for what ever reason, I put the screw in 1st then set the battery and was easy to set the new battery. Charge was at 94% strange seeing it next to my Iphone 6 but glad I did it as now I can use it for music and save the battery on the main phone. Thanks for a easy instruction guide.

ok new problem, drained battery as instructed, pugged it in and nothing 3 different cords and also my car charger were tried, nothing worked removed battery and checked contacts a few times still nothing, any ideas? thanks

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.

The grey cable on the top right of the 1st picture might be confusing, it's the connector with cable which you'll disconnect in step 9 only, so you can't see it this way in this phase.

Be careful to make sure you don't pinch the clear plastic tab under the mobo when reinstalling. :P

Box 3 BOx 3 Box 3 petite vis a gauche

I had trouble with my SIM card at this point. It wouldn't go all the way in - only about 1mm short but enough to keep the phone from being able to read it. It seems that the red screw in this step is the culprit. I loosened it up a bit and the SIM card tray was able to fit flush.

Use the 1.6mm screw standoff as leverage against to lift the connector.

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

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

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

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

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

be extremely careful to check that there isnt any metallic conductive glue sticking, some may remain attached to the motherboard-connecter position in its space on top of the logicboard

So if that glue does stick to the 'motherboard', does it damage the phone?

This is held down by adhesive, don't try to just yank it off. Peel it slowly. If you damage this cable, you are slightly screwed.

Peel back NOT off. It needs to just pull aside. If it comes off, throw the phone.

I did tear the cable. How do I get a replacement , and at what cost ?

NOTE: When replacing the logic board, be sure this antenna remains exposed and doesn't become trapped under the board.

Just wondering if it is possible and where to get one of those indicators

what are you talking about here???

Yeah, would like to know the value of the little blue inductor ... my iPhone 4 doesn't have it any more and I have the worst signal.

I wasn't sure how to carefully detach the antennae. Can anyone offer some insight on how to reattach the antennae? Is it supposed to be soldered to the board? Or is it a pin attachment?

see that tiny little blue thing just to the left of the antenna connector but before the screw? make sure you DON'T knock that out of place otherwise your iphone becomes a heavy ipod touch (yes. this idiot made that mistake while struggling to get the antenna connector back in - which for the record just clips back in). this would have been a handy tip for me while i was reading the instructions, which apart from that little trinket of information, were very easy to follow.

-dan

Be careful, I almost damaged this specific screw by using a Phillips #00 screwdriver. It's screwed in tighter than most others. You will need a Phillips #000 or else your #00 has to be a really sharp one.

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.

Get a set of these precision screw extractors. I own a small electronics repair shop and I wouldn't be without them. If you buy them remember that the ends are reversible in case you dull one end. http://www.ifixit.com/Tools/Precision-Sc...

If a nut under the YELLOW screw is rotating, hold the nut with tweezers.

Somehow i twisted the head off of the 4.8mm screw (ground) during reassembly and not i have terrible wifi. Trying to come up with a solution.... any suggestions?

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.

Print this image out (step 13) - trust me, you'll need it later!

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!

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.

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...

Does any one know where to source a replacement for the little round "nut" trapped between shield and nut. I have lost mine... the yellow 1.4mm screw fits into this... it has a knurled edge.

It seems it should be captive soldered to the MB, but it comes lose...

Do you need a different screwdriver for every one of these screws? They all seem to have different sizes.

The second of the Two 1.6 mm Phillips was stripped...or I stripped it? So I got this far and now i'm retreating and putting the iphone back together. Was going to sell on ebay but now I can not. Oh well...

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.

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.

the nut of the yellow screw falls be careful ...to re install it again

watch for the connector cover here - it tends to be quite "springy" and may fly towards you when you attempt to release the clips

What do these metal clips look like?

The clip actually looks like it might be a ground. it's gold and is folded in two. There's a screw cutout and something that looks like it physically is supposed to touch something. Phone works fine without it, though.

Can this be cleaned with isopropyl alcohol?

I left this part out, and my phone still functions properly in every way I can see. I have proper wifi, cell service, flashlight, both cameras work, vibration works, and speakers work. What is the function of this piece?

the rear camera has an extra long tab which runs under the digitizer cable - be careful not to bend this while removing the camera.

To avoid damaging the Main Camera, it will probably be better to do Step 18 first before doing this step. This is because part of the camera is actually under the Digitizer and LCD cable.

Took me a few tries to get the camera seated properly - if it's not seated correctly, you'll have problems attaching the WiFi antenna. Should sit flat and square.

Just to clarify, the little tab on the side of the camera does not go under the motherboard, it goes under the cables. This misunderstanding is common for those new to mobile repair. Always make sure you take notes on the small things like this!

There was no screw underneath the warranty sticker or even a place for a screw. Disappointed.

I have a big Problem with this screw, it seems that it is more stuck and weaker than the other screws. Now the Phillips screw is totally !@#$%^ up after several attempts of trying to get it out, do you have any idea how i can get it out?

Danger! Since the last screw I took out before is the 4.8 mm (step 13) it can happen that one messes up the order and uses this one instead of the 2.4 mm! This will break the new Display again. I'd add a distinct warnig here to use the right (short) one.

Now I'll a order a new display...

I agree with Ed Williams: no screw under the sticker on my phone.

Step 16 is very simple but unfortunately, the screw spins and spins but can not remove. It is still tightly in place. What is causing the screw to spin and spin. I have this bad feeling that is may be broken inside. Any advice

Removing this is the end of your warranty. If you have any second thoughts on this repair, turn back before this step.

What are these types of connectors called? anyone know where to order just the connectors? or even better would be extension cables

blue, green and yellow down, orange and red up. red BEFORE orange, as part of the ribbon is UNDER red.

unklbyl

when i was replacing the logic board a small gold piece came off. It is above the top left corner of the orange box for the LCD cable. What is it for?

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 re-plugging the yellow connector (the leftmost of the 3 connectors that you disconnected from the top) put the cables behind and not before the metal part with a hole where the EMI Shield 2 clips in. Otherwise you will not be able do step 13.

Be carefull of a very small component soldered near the yellow connector. It can pop off and make your front camera irresponsive.

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. Also, the first time, i did not press the LCD cable very well, so the phone was working, but no display showing. once i snapped this in place the second time, it worked like a charm.

After reassembly, when I changed to the front camera, the display got stuck in shutter mode. The website bellow suggests I lost a microscopic jumper that enables the front camera. I am guessing this happened when I disconnected the 3 connectors. The dang jumper is so small I never even noticed that I lost it. Oh well at least the rear camera still works... After replacing screen camera app now stuck on shutter?

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.

There is a small rectangular rubber bumper on the top of the logic board. You can see it a little at the top of the picture. I knocked mine off and had no idea where it came from! Took my wife forever searching the pictures to locate where it was from.

Take care to put the small ruber piece into place to protect the ribon cable for the lcd dyplay

When reassembling, ensure the ribbon cables for the connector are between the silver metal and the circuit board. the wifi antenna plate clips into the silver metal.

Note where the little rubber thing is. It's there to protect the digitizer and LCD ribbons curving over the top of the mobo. If you do these a lot, you're going to have a WTF moment when you go to put it back together and you have this short rubber strip....

where can i buy logic board from the iPhone

be careful when putting the logic board back in: i trapped the lower antenna cable under it (see step 11). Also, it 'hooks in' at the top and rotates down; there is a notch cut into the outer case to capture the top of the motherboard.

Missing rubber guard can causing touchscreen sensitivity & accuracy problem.

Note that when re-installing the logic board, do not forget about the antenna connector near the bottom of the phone. Make sure that it does not get trapped under the logic board when you are placing the logic board in the case.

Ear piece metal connectors: You can see them on step 22. If those are not bent up enough (laying flat) you won't have contact with the logic board... and no more audio from the ear piece. This is what happened to me. I had to unmount it again to bend them and hop the ear piece worked again!

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. There will be a bit of spring in it when you push down which is a combination of the folded LCD and Digitizer Ribbon Cables and the two copper contacts underneath.

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.

hi, the small gold prong (step 19) in my phone is fragile what should i do? what function from that small gold prong? thank you

I found it easier to do step 19 after removing the screw (step 20)

step 20 speaker screw was stripped from the factory! aaaagh! took some tweaking but got it out using a little drill bit and forcing a standard screwdriver in the divot and cranking it out. the screw is absolutely necessary to reinstall too, so that was tough.

that screw is unscrewable!! I think the factory ruined the cross while assembly and no screwdriver can grab it anymore!!! arrggg... coming to this point it's already so hard.. I don't want to re assemble everything without fixing this home button!!!

the EMI fingers are VERY fragile...

'and then there were THREE' yup i broke off one as well. hint on re-assembly; put in the speaker box, and working from left to right, apply a fair amt of downward pressure and use a tiny flat-blade screwdriver to push the tip of the emi fingers toward the speaker box, go left to right so you can put in the screw on the right side when done.

I broke off the right-most one (closest to the microphone) and after reassembly my signal strength was poor and dropped easily. I replaced the antenna/speaker unit with one from a 4s (the cable was a touch longer; but, solved with some bending) and made sure to really clean the contacts (and not break any)... long story short, intact fingers and cleaning has resulted in better signal strength than prior to the repair! go figure!

I agree they are very fragile! I broke off 1 EMF finger by pressing it down - wish i had read comments 1st! Phone still seems to work Ok, but gave me a scare.

There is a square, metal bar that fits into a slot on the right side of the vibrator. The 1.4mm screw threads into this bar. It fell out when I first flipped it over the phone to remove the screen. Look out for that.

On reassembly I broke the 1.4mm screw. The head fell off and the thread stood within. It worked fine attached just by the other one, but caution when fastening these 1.4mm screws.

When I removed the screw from here I also found a small rubber piece. It is about 8mm long and 2mm wide, and it has a channel down the centre of it. I couldn't figure out where it came from but the phone seems to be perfectly fine without it. I thought it could possibly be some sort of anti-vibration damper for the vibrator although I am not sure. I couldn't see it in any of the pictures.

You can find ist on picture step 20 - right down under the red circle, between frame an speakerbox

The rubber piece Thorsten is describing is a different one, smaller than the one The Talent is mentioning. The one with the channel down the centre of it, I dont know where it goes.

hi,

what do i do if i have lost that screw i droped it and now i cant find it does it matter if i dont put it in?

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 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. I found this the hardest part of the whole reassemble process.

However, the four "1.5 mm Phillips screws", in each of the four corners, will need to be completely removed (and, subsequently, replaced during re-assembly).

Removing the washer and screw is easy, but getting them back on is extremely hard unless you have midget fingers. The magnetic driver really doesn't help, just keeps dislodging the washer in its place when attempting to to reinsert screw. Using a non magnetic Phillips 0.

i couldn't get all the large headed screws out, two where stuck. So i gently removed all the other screws in the following steps, and pulled the front cover gently out by moving gently and breaking some parts of the front screen (which i throw away anyway) After that the remaining screws became looser, and were able to screw up and down.

Great guide. When you are prying the glass screen off be extremely careful not to lift the top of the too high. If you do lift it too high then the glass at the bottom of the phone will easily crack.

My glass refuses to budge ! I broke two ipod tools trying to get the glass off ! Reassembling phone, will try again some other time... There has to be an easier way to get the glass off...

If you use a hair dryer to soften the glue, it seems to do the trick. Just dont hold too close to melt anything. Did this with an Atrix a few times.

Definitely use a hairdryer to loosen the glue below the power button to get the spudger started.

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.

I just need it to work for a few more months until the iPhone 6 comes out.

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.

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!

I have used clear tape placing it on the screen so that the shards of glass will stay in one piece. This worked out for me hopefully someone will try it.

Removing the screen in the step was a little tricky… The home button got stuck in the display hole and the ribbon cable broke. Another 20$ down the drain…

It is indeed easy to pinch the digitizer cable in particular between the top of the glass and the metal backing underneath. Be careful.

one of the cables has a fold or something making it 'double' so there are really THREE cables that must be fed through the hole (one just doesn't go anywhere). I used a tiny tweezer to aid with re-routing the cables and it was FAR easier.

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. Also if you need to replace the camera ring, your prob gonna have to replace the ear screen, its easier in the long run just to replace it. Please do not glue either piece on.

Sounds dumb but make sure you remove the (usually blue) protective sheet from the mirror surface on the interior of the new display. I didn't and I had to redo the whole process!

CAUTION! When rerouting the LCD and Digitizer cables, DO NOT PULL ON THEM! I tried to re situate the Digitizer cable in order to mount onto the speaker enclosure, which broke the digitizer right off.

This is the only part that was a little tricky for me. When I was reinstalling the LCD panel it took me a few tries to get the connectors and cables through the holes correctly, and not pinched by the frame. Take it slow and be gentle.

My bf claims I have to replace the LCD if I take it off. Is that true?

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!

It's easy to get the digitizer cable caught and sandwiched when reassembling, make sure you carefully feed it through. I got everything almost assembled and then the digitizer ribbon cable wouldn't reach the connector! I was stuck for 45 mins till I figured it out.

For some reason when I put the phone back together the screen is dark on the upper left corner. The touch sensitivity works perfectly and the button replacement went well.

I ripped the LCD cable pulling it too hard, is it fixable?

At this point make sure that you don't have any broken glass left on the phone. I had, and the screen wouldn't go all the way down.

CHECK AND DOUBLE CHECK THE RIBBON CABLES BEFORE YOU PUSH IT DOWN! It really is very easy to mess the whole thing up here...I did! Even when you think you've got both cable through, check from the side, there's a little square bit that catches. If you damage the ribbon at all it's time to buy a new screen and learn from your mistakes.

Im at the steap where you have to put the lcd screen and the frame together but at the beginning of this steap removing it! 2 small pieces felt off and I can't find where they belong any one

Don't forget to change the adhesive strips if they're dirty or not enough sticky or your screen will break more easily. :(

Does both cables (digitizer and screen) go through the same route (hole)? I did not pay attention while opening the phone and now passed them through the same area. Now the digitizer cable does not reach the board! What should I do?

be careful how you re install them cables one of them might stuck on the board ..

thank you Andrew!

My screws were all stripped and messed up so ordered new ones, It is now time for resassembly and I am lost! What goes where?! Any tips on how to go about doing this? I have got the main screws and washers in the side and now, I am 100% lost!

when I peeled off the red protective piece, the chrome backing also came off with the red protective film!

Did this just ruin my LCD screen?

After reassembling it I can hear sounds, but the picture is black.

the chrome backing is also coming off mine! Did it work for you????

The Silver layer come with the transparent film in my case...
