Guide To iPhone 4 Screen Replacement

Featured

After having dropped my iPhone 4 while in its case and finding out the screen was cracked, I was determine to find a fix. Before when I had an iPod touch, 2nd generation, the screen was easily removed. I took out the pins from the front of the screen of the iPod; and in the  iPhone 3 and 3GS's case the screen popped out after removing two screws. I assumed it would be as simple as that having done the procedure plenty of times for my friends broken gadgets.

After buying this expensive phone my self and having to pay for yearly internet usage, I figured, I would take great care of it and skip the care protection plan. I did take extensive care of it, I used a screen protector along with a case and never had any problems until a few days ago. I was sitting on a bench out side of school (bench was about 1 and a half feet from the ground) with my phone laying beside me I must have gone to grab it, but the phone slid off the bench and hit a mulch surface.

I assumed one little drop couldn't do harm to a helicopter glass grade panel but when I went to pick it up I saw the ungodly crack under the screen protector. I am trying to say that this was an unlikely hit to the phone. As soon as I got home, I looked up replacement parts for the phone and a quick tutorial. My recent fixes with previous Apple products gave me enough experience to say: BUY A FULLY ASSEMBLED REPLACEMENT PART. The vendors on eBay and sites like those are not out to help you, they are just looking for your money. You need to make sure you do the research before you buy the parts. So be smart when you buy the replacement; I proceeded to buy a fully assembled retina display and glass piece. THESE PIECES SHOULD NOT BE BOUGHT SEPARATELY.  I STRESS THIS BECAUSE APPLE DOES THE LAMINATION OF THE TWO TOGETHER WHICH IS IMPOSSIBLE TO DO BY HAND. If you have ever done an Apple product repair such as iPod touches or iPhones, you would think that the LCD and the Glass are two separate pieces. Instead on the iPhone 4,  Apple decided to use lamination of the two to reduce the glare. That feature  was effective and took out the variable of dust particles getting in to the phone but makes the replacement of one twice the amount of money.

Thank you very much for your help!!! I've just changed my screen, it took me about 3 hours, but notice that I'm a girl, and my native language is not english! Even though , your post helped me a lot with my schematic and I watched some video tutorials during the repairings ! I waited almost a month till my replacement parts and tools arrived and I was anxious to do it myself, cuz here in Bulgaria, othorized repair shops want tripple the coast I bought the items ! For the hour my Iphone 4 works again it is doing fine, but I'm a bit worried for my Wi-Fi signal, becaouse it's a bit low. So I was wondering if I did something wrong when I repaired it?

I have a huge problem, my phone has no service when I turn it on. the instructions were great on changing the screen. I double checked each step to make sure I put the phone back to together correctly. Now I have a phone with no service! :(

please help~~
Hopefully you've resolved this already, but I'm going to post this in case someone else has the same issue later. The problem was likely that the antenna was not connected. Without an antenna connected, everything else would work but you would have "no service".
Most likely, the little RF connector that goes from the black plastic speaker/microphone module to the mother board was not seated properly. In the pictures for Step 12, you can see this next to the battery connector. The cable looks like a round wire attached to the speaker/microphone housing, and the connector is the silver 'frying pan' shape on the end. This has to be lined up properly on the motherboard and then pushed down firmly. Ideally, you'd feel a little 'pop' as it seats.
To check this, just repeat the first steps to take off the back cover and the battery connector, then try flicking the antenna connector with your fingernail- if it moves, it's not connected.

hey, sorry this happened, Ive had this problem before, what i did was i took the sim card out and put it back in, if this doesnt work try rebooting the phone by holding the home and the power button for like 15 seconds. if that does not work make sure all your ribbon cables are in place correctly, if that doesnt work take it apart until you reach the mother board and put it back together, you may have missed something. If you end up not having any success try calling your provider, i would leave out the details about fixing your own screen :) hope this helps keep me posted!

Nice job documenting this process. I just replaced a screen for a co-worker and this was a big help.

One tip- you can simplify the process in Step 14: For the "A" screws, loosen them but don't remove them. This way, you don't have to fumble with the screws and washers when you re-assemble. When you put it back together, just stand the frame on its side and tap gently to settle the washers against the screw heads, then slide the ears of the new screen into place (you can use an X-acto blade tip to move the washer if the gravity method isn't working). Holding it together, turn it over and snug the screws just enough to hold, then repeat for the other side. Once both sides are seated with the ears on the correct side of the washers, place the phone face-down and firmly press the frame down to eliminate any gaps between the frame and the face-glass, then tighten the screws and install the four "B" screws.

You may have to fumble around a little with getting the screen ears between the washer and the frame, but it's still far easier than getting the screws and washers back into the holes.

Thank you so much for this tutorial! Yes it took way longer than I thought but I couldn't have changed my white cracked screen to a pretty uncracked red one. You are a champion and I cant tell you how many tears and swearing fits you have saved me and my family too. MWAH!

You have helped me decide this isn't something I want to do for a 'friend of a friend'. Thanks.
Does anyone have any recommendations for replacement assemblies on amazon? Any sellers/companies to stay away from?

You can easily magnetise a screwdriver if you need.
Simply swipe a magnet along the rod in one direction and with one pole of the magnet.

This by far was THE most helpful part of the instructable. I used pieces of clear tape to tape the screws to schematic to keep the screws organized.

TAKE OUT THE SIM CARD IF YOU DIDN'T EARLIER! If you didn't and don't, it will come back to bite you in the arse in this step.

Is it possible for someone to send me a side profile of the screw marked 'screw 2' in the first picture? I had lost this one and ordered a replacement set of screws from eBay but none of them seem to fit and there is no hole to screw it in as the bit it touches is a copper circle. It would be greatly appreciated if someone could do this for me. Thanks. Kris

For this section you can untighten the 6 screws on either side without taking them off as the clips don't go all the way round the screw. Plus it can be a bit of a fiddle getting the screw and washer back on if you take it off fully. Just slacken them a little to make it easier ;)
Why not verizon????

If your phillipshead screwdriver doesn't fit at this point, you are screwed.(LOL pun)
Apple decided to put very weird pentalobular screws (5 point star) in there. iFixit has some good tools, and a set of screws to replace them with normal phillips screws. Or look on Dealextreme for the tools. But they don't have just the replacement screws. Only all the screws.
LucasOchoa (author)  wouternet2 years ago
haha, i would advise to stay away from ifixit because of there unreasonable prices, amazon will do fine. thank you for your input i greatly appreciate it.
I agree, I bought stuff from them before and even though it was a bit pricy i thought it would be good, I replaced the screen on my iphone 4 with theirs and the screen came on but was unable to get the touch part working. Unfortunately I cant send it back, and dont want to get another from there as I heard there are many bad ones. All I really need to do is find someones old one and swap out the motherboard, i just want my stuff back from my old one.
You're free to add it to your instructable.
lol, must be some kind of joke, if you cut an apple in half it looks exactly like the screws
This is awesome! Thank you!

Great , thanks for share,i had grabber all fixed guide here https://www.facebook.com/pages/Erednet-Community/486951567999130?ref=tn_tnmn
Does the new screen work the same as the old one? I wonder because apple is bound to be upset if someone were selling apple parts, so they must be 3rd party and that's probably highly guarded technology. Not trying to be critical at all, just wondering because I need to the same thing.
Great and detailed 'ible, well written

the parts are exactly the same depending on where you order them... there may be a little variability it quality of packaging but mostly you can get an exact replacement. thank you for the comment

Hi,
I have an Iphone 4s with a creaked screen and am looking to buy a new screen off Ebay. Was just wondering if this one is reliable. Here's the link, (http://cgi.ebay.ie/ws/eBayISAPI.dll?ViewItem&item=250927151154).

Thanks.

These are now available in the UK. I bought mine for £34.99 inc delivery from

www.fonerepublic.com

It was the cheapest place I could find selling the OEM parts.

Hi,

I broke my Iphone yesterday and then found your excellent description of the LCD/Digitizer replacement. Thank you!!

One thing though. How do you ensure you buy a proper Retina display and not just some junk/replica? The first of your links above is not working, could you maybe recommend a supplier of an original Apple quality black LCD/Digitizer?
