In detail: do-it-yourself iPhone repair from a real master for the site my.housecope.com.
Hello. Why so sad? Screen broken? Well, to hell with him ... Is it worth getting upset because of this? After all, there are more important things in life. But in general, iPhone screen replacement is not that difficulteven if you do all the work yourself. If your hands do not grow out of the “ass” (sorry) and you have at least some experience with the tool (you can hammer a nail into the wall ... well, or cut it with a jigsaw on plywood), feel free to read the article to the end, where I will tell you how DIY iPhone screen replacement.
In this article you will not find instructions a la "open here, stick here...". Today I will give you more useful information, namely what is needed to replace the iPhone display, where you can buy all this and how to save on repairs by following all the steps yourself (according to the instructions with pictures).
For convenience, this article is divided into 4 steps. Each of which has its own characteristics and nuances. Go!
The fact that the glass cracked, we already understood. Now we need to decide what we are going to change. If the screen is covered with stripes and has become unusable, a complete replacement of the screen module is necessary. If only the glass cracked, and the screen remained intact, many people have the question “So can only replace the glass of the iPhone and thus save on the purchase of a screen module?».
I perfectly understand the desire to save money ... But first, let's figure out how the iPhone screen works and what the iPhone glass replacement process is like.In fact The iPhone screen is a glued multilayer sandwich of glass, polarizer film, IPS matrix and backlight layer. All these layers are glued together with a special glue with a tricky name. Liquid Optically Clear Adhesive (LOCA), which translates as Liquid Optically Transparent Glue. So, in order to tear off the glass from the screen, you need to try VERY hard, and it’s not a fact that you will succeed. The myths that you can replace ONLY GLASS on an iPhone at home, almost with the help of a bank plastic card, are far from reality.

Watch how the glass of the iPhone screen is separated (video below) in professional workshops for the restoration of screen modules. The guys were well prepared and purchased the necessary equipment. A thin metal string is used to separate the glass from the screen. In this case, the screen lies on a heated surface, which in turn softens the adhesive. Reassembly also requires "some skills" ... Well, what am I telling you here. It’s better to see for yourself how professionals restore broken iPhone screens, and then decide for yourself whether you can do the same.
Of course, you can try to separate the glass from the screen without such a gravity cap, but the chance that the screen matrix will simply burst under the onslaught of your hands increases. In addition, at home, doing everything on your knee, you will never get a high-quality assembled screen. That is why I do not recommend restoring/repairing screen modules on your own, but it is better to replace the entire iPhone screen.
There are two ways... The first is to search in Russia, Ukraine, Kazakhstan, etc. on local classified sites or online stores accessories for iPhone. Google will help you...The second way is buy screen for iPhone on AliExpress.com. Personally, I have already ordered screen modules many times on the AliExpress website, and this pleasure cost me $35 (for the iPhone 5C model) ... The price was about two times cheaper than for the same screen, but in Ukraine. When buying on this site, the buyer has about 50 days to confirm receipt of the goods of good quality. If the screen does not suit you for any reason, you can return 100% of the money spent.
Here are links to tested screen modules for different iPhone models:
- AliExpress: iPhone 4 / 4S - link
- AliExpress: iPhone 5 / 5C / 5S - link
- AliExpress: iPhone 6 / 6 Plus - link
- AliExpress: iPhone 6S / 6S Plus - link for 6S | link for 6S Plus
- AliExpress: iPhone 7 - link
If you really want to save money, then I would advise you to go the second way and buy an iPhone screen on AliExpress.and then install it yourself. The Chinese have learned how to make good quality screens that are almost indistinguishable from the original. Replacing the iPhone screen is not difficult... it just requires care and precision.
The display usually comes with tools to replace it. But I want to warn you against using at least screwdrivers. They are of such cheap quality that you can easily screw up the bolts at the end of the phone. It is better to immediately throw out these screwdrivers.
But you still need specific tools (pentalobe screwdriver, suction cup, spatulas, tweezers, etc.), which can be purchased for a penny on the same AliExpress. It is better to immediately buy one set, which will include everything you need. For a beginner, a set is suitable, which I recommend at the link below. It includes everything you need to take your iPhone apart down to the last screw.
Now that you have everything you need to replace your iPhone display, all that's left is the repair work. I'm just sure that everyone can do it. Trust me, and you too! There are no tricks here, the main thing is to follow the instructions clearly, take your time and be careful.
Regarding the instructions ... the bourgeois have a very good site ifixit.com, where they lay out detailed manuals for the repair of any equipment, including the iPhone. Below I have provided links to step-by-step instructions for replacing displays of different iPhone models. The guys at ifixit messed around with each tutorial and provided them with macro photos and videos with detailed descriptions.
Screen replacement instructions for different iPhone models:
If you briefly describe the process of replacing the iPhone display, you get the following. Hit is necessary to unscrew the two Pentalobe bolts at the end, disconnect the screen and touchscreen cables, remove the screen, rearrange the camera, light and proximity sensors, as well as the HOME button from the broken screen module to the new one, perform the iPhone assembly steps in reverse order. Easy-peasy… No, well, it really couldn't be easier.
Fair question though. If you yourself change the screen sstsykotno, you need to know how much this service will cost from others. Let's take for example the Total Apple service center with average prices in Moscow. Actually, the prices themselves are lower, well, they include the cost of materials and “slave services”:
Average prices for iPhone display replacement services:
- iPhone 5S — 3490 rubles ($60)
- iPhone 6 - 4490 rubles (77$)
- iPhone 6S - 9990 rubles ($171)
- iPhone 7 — 19,990 rubles ($342)
If you compare the price with AliExpress with the price of a service center, it becomes clear that self-replacing the iPhone screen will cost two (or more) times cheaper. You can really save money. If I haven't convinced you yet, watch the video tutorials on ifixit.com, there are even girls who disassemble phones, and they do it with ease.
A broken iPhone screen is nothing! Do not be afraid to fix things with your own hands. Try - and you will succeed!
iPhone, today it is considered the most popular and popular mobile gadget from the American trade brand Apple, which also has impeccable quality.There are practically no production defects and defects in such phones, and all breakdowns are formed only through the fault of users.
Manufacturers are very responsible in the manufacture of this device, however, not every owner is reverent and careful about the operation of this complex device. Often a careless attitude leads to damage and it is necessary to eliminate these defects.
But these actions can be carried out independently by reading our recommendations.
In this article we will try to explain how it is possible to repair this device with one example with our own hands. You can also independently disassemble the gadget, replace components (covers, screens, batteries, etc.), replace vibration components.
The company produces several modifications of the iPhone (iphone 2g, 3g, 3gs, 4, 4s, 5, 5C, 5S, 6, 6+, 6S, 6S+, SE, 7, 7+), which are of very high quality, but breakdowns still happen and you can do it yourself.
Using our instructions, you will have a great opportunity to fix the problem.
Before disassembling your device, decide why you need it at all, because it belongs to a very complex technological device and when disassembling it is easy to damage important components if you do not have enough experience. If you nevertheless decide to carry out repair and restoration work, perform these actions only if you are absolutely confident in your abilities.
You must be aware that all the activities you perform are putting your iPhone at risk, which may lead to further malfunctions.
So, let's take a step-by-step look at how you can replace the microphone in the "iphone 4". To do this, you will need the following parts and tools (synchronization cable, special screwdrivers, spatula for disassembly).
That's the whole step-by-step instruction that we wanted to offer you. We hope that with patience, courage and allocating enough time for this, everything will work out perfectly. We don't tell you how to put your phone back together, just follow the instructions in reverse order.
If you could not make a replacement, you always have the opportunity to call a professional service center, for example, a mobile device repair service center. "MakeApple", which specializes in the repair and restoration work and service of iPhones.
The most common problem of iPhone breakdowns, as well as other mobile phones, is gadgets filled with various liquids when moisture penetrates inside. In such a situation, you should not carry out repairs on your own at all, or expect a miracle that everything will dry up by itself and the iphone will work on its own.
The easiest failure is from flooding with any liquid, this will cause the controller to close (after drying, the device can work, but the battery runs out quickly). You cannot do anything on your own, here you need to carry out diagnostics and professional complex work on cleaning and repair.
In a situation where you are faced with a problem where you doubt that you will fix the problem, it is best to contact knowledgeable service center specialists. "MakeApple" (link above), where you can always turn for professional support and free advice.
The process of separating alcohol from mash is called - distillation or the process of stripping alcohol. (article for persons +18!) Almost all new phones from Apple are bestsellers. They are very popular and forever won the hearts of most consumers. These gadgets are very reliable, functional and convenient. Despite their qualities, all iPhones, like all other smartphones, can break down. More often than not, the consumer is to blame. In a large number of cases, you can repair the iPhone with your own hands, but it’s better to contact the service center specialists anyway. Apple Restore , they offer a free new service to call an Apple repair technician to your home, work, or other place convenient for you. There are not so many main causes of iPhone breakdowns.These are software-related breakdowns (programs close by themselves, the phone “thinks” for a long time), which occur if there was an intervention in the base platform or an incorrect installation of some application was made. The next type of breakdowns are breakdowns associated with the fact that the phone was dropped on the floor, something was dropped on it, and in the end they sat on it. Repair after such operations with the phone is not done quickly, and it is not cheap. A more serious breakdown may be a short circuit resulting from liquid getting on the iPhone's circuit board. Repairs can be very expensive, or it can happen that the phone cannot be repaired. The most common breakdown is the failure of the display or touchpad as a result of the phone being dropped on the floor or asphalt. This breakdown can be fixed on your own and not contact the service center, paying large bills for repairs. So, first you need to unscrew the two bolts that are located at the edges of the cable connection connector. Then you should carefully remove the top panel along with the display. This can be done with a regular suction cup or pry off the edge. From the end of the removed panel there are still small bolts, which should also be unscrewed from both sides. There is another bolt next to the cable, which must not be forgotten to unscrew. Thus, the display cable and the touchscreen were disconnected. Now the display with a metal frame must be removed. This can be done with a knife. We take a new display and, if the touchscreen is in order, we assemble the phone. But, if you need to replace the touchscreen, then the removed display must be put aside. In order to separate the touchscreen from the metal frame, you need to take a building hair dryer and heat it around the entire perimeter. After this procedure, the touchscreen should be separated from the frame with a scalpel. Next, you need to take a double-sided thin tape and stick it around the perimeter on the panel body. The new touchscreen must be glued to the adhesive tape and the phone must be assembled. Of course, all these manipulations are not difficult, but there is one “BUT”. During such repairs at home, there is a high probability that other parts of the gadget will be affected and damaged, the repair of which will result in a tidy sum. Here is a video tutorial for self-repairing iPhone 5. Select your device and see how to disassemble the phone and properly replace the damaged part. We will show you how to fold the phone back. We are always happy to help you. After the breakdown is determined, you can buy all the necessary spare parts in our store. They are high quality and original. Do-it-yourself iPhone 5 repair can be done without problems. Before making repairs with your own hands, you will need to determine the damaged part. The Telemama service center has been selling spare parts and repairing equipment for a very long time. You will not be able to fix every breakdown on your own. If you want the repair to be performed efficiently, not expensively and quickly, come to the Telemama service. Diagnostics is provided here for free. To view all prices, you need to look at the price. We very often hold promotions, which will allow each of our clients to repair the device almost at cost. Regular customers do not expect discounts. We took care of everything and made a special price list with the lowest prices for them. According to many surveys, the iPhone is the most popular phone in the world today. Popularity did not come by itself. To achieve it, first of all, a well-thought-out advertising campaign was created. Not the last factor in all the work was the impeccable quality of the device. Together, these two aspects played a role in the promotion of iPhones.It is known that the owners of such devices very rarely turn to service centers due to a factory defect, since it is almost completely absent. If the creators took the production of the iPhone very responsibly, then not every user can boast of careful use of the phone. Therefore, breakdowns happen quite often (due to the fault of the buyer). In service centers, breakdowns such as broken touchscreens and moisture inside the phone are most often recorded. Such trouble can overtake any Apple device. You can find a list of malfunctions that most often occur due to the fault of iPhone users on the website. Given the high cost of repair services, there are cases of self-troubleshooting of smartphones. Masters who are at least a little versed in the Internet think that they will resurrect their phone with the help of search engines and numerous forums. No one can become a professional just by typing the phrase “iPhone repair”. The iPhone is a complex technique, so the positive and negative sides of the “home craftsman” begin to emerge along the way. The main plus of home repair is that it is completely free (this is the case if the owner can cope with the task). In most cases, in practice, it turns out that later, after such repair work, you have to pay a larger amount than the one that was originally expected. The most common mistake is replacing the touch screen yourself. In order to really repair the touchscreen (or protective glass), you will need special equipment and tools, which, most likely, you simply cannot find. You will be able to replace the screen, but how long it will last will only be known along the way. After independent interventions, you only have to believe that this period will be as long as possible. And most importantly, after repair at home, the factory warranty will cease to be valid and if you need to carry out repairs at a service center, then all work will only be paid. Although there are such “home repair masters”, after which even the service center will not be able to help the device. But I would like to clarify that there are such problems that almost every iPhone owner can solve: outdated software. You can update it yourself, however, it is worth using licensed programs recommended by the manufacturer. After a large amount of information, I still want to say that it is better to entrust iPhone repair to knowledgeable people. Although if you are a person who likes risk, you can try, but do not forget that as a result you can pay a decent amount of money.

The abundance of video materials do-it-yourself iPhone repair, freely available on the World Wide Web, often encourages smartphone owners to take on their own repairs. Watching any video in which the wizards replace the power and go to the desktop buttons, fix various other problems, users try to have time to repeat every movement after the service engineers.At the same time, they do not always realize that such training videos are posted on the network, first of all, not for ordinary users, but for specialists with practical experience in restoring the device's performance. Why do-it-yourself iphone repair does more harm than good desire to fulfill do-it-yourself iPhone 6 plus, 5s, 4s repair most often begins to visit smartphone owners after visiting one or more service centers and getting acquainted with the cost of their services, which, depending on the type of breakdown, can cost more than one thousand rubles. However, self-repair can be fraught for the owner of the phone: However, all of the above does not save them from breakdowns: as a result of mechanical damage, contact with water and inaccurate use, an expensive device can fail for a long time. To bring your broken device back to life, you will most likely need an iphone repair. But in no case should you try to bring the gadget back to life on your own, as this is fraught with a final breakdown of the device.

To fully restore the functioning of the iphone, the repair must be carried out after a preliminary diagnosis, which will reveal the extent and cost of restoration work. To restore the health of an "apple" smartphone, the following types of work can be performed: Repair of iphone at the price and duration depends on the type of repair and the qualifications of the company's employees. For example, replacing glass and display takes about 20 minutes and costs about 5 thousand rubles.Replacing the battery takes about an hour and costs 1500 rubles. Some service centers, trying to attract more customers, are dumping (offering prices for services much lower than market prices). But it is not recommended to use the services of such companies, since the quality of repairs in them leaves much to be desired. And instead of a repaired gadget, you can get only wasted money and a broken smartphone. It has been said a thousand times: do not self-medicate, but still there are people who think that there is nothing complicated in repairing an iPhone. The Internet is full of sites with instructions on how to replace the screen in an iPhone, or change the battery in an iPhone 6, and YouTube is full of videos on the topic "how to disassemble an iphone." This leads to the fact that everyone who has a screwdriver begins to consider himself an electronics repair engineer, and this is not so. Further more: And there are more and more such clients, and if in the case of the iPhone, you can get by with replacing the main board, which is quite expensive compared to the cost of an iPhone, then replacing the motherboard of a MacBook is equivalent to the cost of a used computer. Trust the professionals, and don't skimp on the repair of quite expensive Apple digital equipment if you want to continue using your gadget, being sure that it will not let you down at the most inopportune moment for this, for example, on the way to the airport.

Apple blog: here you can find both useful information related to the repair of Apple computers, iPhone, iPod and iPad, as well as read about the curious cases that arise in the course of the service center. Question from a reader with the nickname himrus11: Hello! Is there any procedure that allows you to eliminate all sorts of minor scratches and scuffs without replacing the case? So to speak, cosmetic repairs. The specialists of the ModMac service center answer: Hello! There are a lot of solutions here. Remember, the iPhone 5 was constantly blurring the edges, and many used a black marker to paint over them. The main thing is to choose the one that will not be erased - probably, the method is also suitable for the iPhone 7. Scratches and scuffs, for example, on a Mac, can be touched up with an ordinary pencil, and some dirt can be easily removed with an ordinary eraser! In principle, you can do all this yourself, and if you want to restore the original appearance, alas, you can’t do without replacing the case. Question from a reader with the nickname chapaj1984: Hello! The problem with the iPad, the speaker wheezes and works quietly, what could be? The specialists of the ModMac service center answer: Good day! Unfortunately, recently this problem has begun to occur more and more often, both on the iPhone and on the iPad. Owners tend to take their devices to the bathroom, where there is a high risk of moisture getting into exposed parts of the device, including through the speaker grille. Also, the cause of this problem could be a blow, not even a strong one. In this case, only replacing the speaker will help. If you have any questions for the experts, feel free to ask them in the comments. We will try to answer everything, but please note that this can sometimes take time - there are a lot of questions. Despite the fact that any Apple product is a complex high-tech device, the malfunctions of which must be fixed by a specialist, a simple do-it-yourself iPhone repair possible, although it is difficult to recommend to users. But, there are different circumstances in life, and therefore it is impossible to exclude the fact that someday you will have to do iPhone repairs yourself, of course. Most of the work related to the elimination of breakdowns of smartphones requires special skills, as well as the availability of expensive diagnostic and repair equipment, but repairs such as iphone display replacement the owner of the smartphone may well produce it, if he shows due care. iPhone screen damage is one of the most common causes of smartphone breakdown and anyone can face this problem. To produce do-it-yourself iPhone repair, you need to stock up on special tools. To replace the iPhone display, the kit will be minimal, but you still can’t do without it. First of all, you need a PENTALOBE screwdriver or, as the people call it, “chamomile” and “Phillips” screwdriver. In general, if you are going to periodically do repairs and improve your skills, it is better to purchase a set of screwdrivers for Apple technology, but this is enough to replace the screen. You also need a silicone suction cup, a plastic spatula and tweezers for small parts. In general, a complete set of iPhone repair tools looks something like this: First of all, you need to carefully unscrew the screws that secure the screen. They are located below and this task is not too difficult even for a beginner. You just need to be a little careful not to damage the screw heads or scratch the smartphone case with a screwdriver. After that, with the help of a suction cup, you need to gently lift the screen, helping yourself with a plastic spatula. In the event that a broken iPhone display is being replaced, it is best to pre-stick adhesive tape on the glass to avoid spilling the part into fragments. When the display is removed, you can see the internal components of the smartphone, but we are only interested in a metal plate fixed with three bolts - it is this plate that hides the cable connectors that connect the screen. After the plate is removed, very carefully, using tweezers, disconnect the connectors, all three pieces. Everything, we can assume that we have coped with this part of the work - the iPhone display has been removed. Let's take a look at the new screen. Before installation, you need to “transplant” the Home button, microphone and front camera. To remove the button, unscrew the two bolts: After that, with the maximum possible care, we separate this part of the button from the old screen, which, by the way, is glued quite well: That's it - the Home button is removed without incident: Let's take care of the camera - it is fastened with two bolts: You must also remove the camera very carefully so as not to damage or tear anything. By the way, do not forget the plastic holder on the old screen, which also needs to be rearranged. Removing the metal plate When everything is removed, you can start assembling and installing a new iPnone screen.Installation takes place in the reverse order and, if you removed the old screen yourself, then installing a new one should not be difficult. But, I would like to remind you once again that accuracy in do-it-yourself iPhone repair, is in the first place, because if something goes wrong, it may be necessary to purchase a new part and unforeseen expenses. Do your own iPhone repair only if you are confident in your abilities, otherwise leave Apple repairs to professionals.

But such self-confidence does not always end in success. Especially with such cunning devices as Apple products. But my friend took his device in St. Petersburg to a specialized iPhone 5c repair service, and of course I started repairing it myself). First of all, it is desirable to find out whether the phone is subject to warranty service. And in this case, it is better to use the services of a service center, in order to avoid serious damage from unprofessional actions that are no longer covered by the factory warranty. If the warranty is no longer covered by the iphone 5, as in my case, you need to determine what kind of breakdown - software failure or hardware damage. Some problems can be fixed with new firmware. If you have experience flashing, in principle, you can do it yourself, but you need to check the health of all cables, since interrupting the software update process can lead to irreversible damage, which life has shown more than once.But, nevertheless, it is better to entrust to a professional than to sit and experiment if there is no solid knowledge in software. Considering the high-quality assembly of the iphone 5, the most frequent are mechanical damages, which lead to the breakage of the screen and case. The front glass is the most vulnerable point of the device, due to its fragility. It is quite difficult to change the glass in the iPhone 5 on your own, since you need to change the sensor and display along with the glass. All three parts are a single module that is not divided into component parts. Check out the glass replacement video:

Ordinary consumers, trying to keep up with fashion, tend to acquire a fashionable and status thing. The latter include the "apple" models of smartphones. Smartphones from Apple Corporation differ from similar devices from other companies in high reliability, innovative design and high price.
In order for your iPhone, after the repair, to look and function as if it had just been taken out of the factory box, it is necessary that only branded spare parts are used when replacing parts. In reputable service centers, the client is provided with a certificate of authenticity for the part.
First, the obvious: there are a lot of instructions on how to disassemble an iPhone, but there is practically no information on how to put it back together. And not always actions in reverse order are correct or obvious.
Secondly, even a simple mechanical repair of digital equipment, for example, replacing a display, implies not only the presence of a tool for opening the iPhone, but also requires the arrangement of an ESD-protected workplace so that an accidental static electrical discharge does not damage the electronic components on the motherboard in the smartphone.
The modern iPhone is the result of the application of design and engineering ideas: huge functionality in a small package. A lot of different-sized screws that seem to be the same size to the eye, and the holes where the screws are screwed are of different depths.
Not knowing the nuances, such an unfortunate master will randomly screw in the screws while assembling the iPhone after replacing the display, and then he will sit and wonder why the iPhone just worked, and now, after replacing the screen and subsequent assembly, there is no image in the iPhone. And there is no image in the iPhone because under the sleeves where the mounting screws are screwed in, there are conductive paths connected just with the display. And this repairman, screwing in a longer screw, damaged them. Restoring the conductive tracks in the inner layers of the iPhone circuit board is quite an expensive repair, more expensive than replacing the display module at an Apple service center.
