In detail: do-it-yourself iPhone repair from a real master for the site my.housecope.com.
Hello. Che is so sad? Is the screen broken? Well, to hell with him ... Is it worth getting upset about this? There are more important things in life. But in general, replacing the iPhone screen is not that difficult, even 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 out the plywood with a jigsaw), feel free to read the article to the end, where I will tell you how do it yourself iPhone screen replacement.
In this article you will not find instructions a la "unscrew here, stick here ...". Today I will give you more useful information, namely, what is required to replace the iPhone display, where you can buy all this and how to save on repairs by completing 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 becomes unusable, a complete replacement of the screen module is necessary. If only the glass cracked, and the screen remained intact, many people have a question “So can only replace the glass of the iPhone and thus save on the purchase of a display module?».
I perfectly understand the desire to save money ... But first, let's figure out how the iPhone screen works and what the process of replacing the iPhone glass is.In fact iPhone screen is a glued multi-layer sandwich of glass, polarizer film, IPS matrix and backlight layer... All these layers are glued together with a special glue with a cunning name Liquid Optically Clear Adhesive (LOCA), which translates as Liquid Optically Transparent Adhesive. 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 a bank card, are far from reality.

Watch how the glass is separated from the iPhone screen (video below) in professional workshops for the restoration of screen modules. The guys prepared well 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 the heated surface, which in turn softens the glue. Reassembly also requires "some skill" ... Well, what am I telling you here. Better to see for yourself how professionals restore broken iPhone screens, and then decide for yourself if you can do the same.
Of course, you can try to separate the glass from the screen without such a gravity, 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 knees, you will never get a high-quality assembled screen. That is why I do not advise you to restore / repair the screen modules yourself, but rather 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 components for the iPhone. Google will help you ...The second way is buy iPhone screen 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 is given about 50 days to confirm receipt of the goods of proper quality. If the screen doesn't suit you for some reason, you can get 100% of the money back.
Here are links to proven display 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 a screen for iPhone on AliExpress., and then install it yourself. The Chinese have learned to make good quality screens that are almost indistinguishable from the original. Replacing the iPhone screen is no big deal ... all that is required is care and attention.
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 in the end of the phone. It is better to throw these screwdrivers away at once.
But you still need specific tools (pentalobe screwdriver, suction cup, shovels, 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, the set is suitable, which I recommend using the link below. It includes everything you need to disassemble your iPhone down to the last screw.
Now that you have everything you need to replace your iPhone display, all that remains 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, do not rush and be careful.
As for the instructions ... the bourgeoisie have a very good website ifixit.com, on which they lay out detailed manuals for the repair of all kinds of equipment, including the iPhone. Below I have provided links to step-by-step instructions for replacing the displays of different iPhone models. The ifixit folks fiddled 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. NIt 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 a new one, perform the iPhone assembly steps in reverse order. Easy-peasy ... No, well, it really couldn't be easier.
Fair question, however. If you yourself can change the screen yourself, 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 "services of a slave":
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 the services of a service center, it becomes clear that replacing the iPhone screen yourself will cost two (or more) times cheaper. You can actually save money. If I haven’t convinced you yet, watch the video tutorials on ifixit.com, there even girls take apart phones and do it with ease.
A broken iPhone screen is no big deal! Don't be afraid to do it yourself. Try it - and you will succeed!
Iphone, today it is considered the most demanded and popular mobile gadget from the American trade brand "Apple", which also has impeccable quality.Manufacturing defects and defects in such phones are practically absent and all breakdowns are formed only through the fault of the users.
Manufacturers are very responsible for the manufacture of this device, however, not every owner is anxious and careful about the operation of this complex device. Often, carelessness leads to damage and you have to fix 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 our own hands using one example. 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 it is possible to do them yourself.

If you nevertheless decided to carry out repair and restoration work, perform these actions only if you are absolutely confident in your abilities.
You should be aware that all activities you perform at risk of your iPhone, which may lead to further malfunctions.
So, let's look at step by step 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, a spatula for disassembly).
That's all the step-by-step instructions that we would like to offer you. We hope that with the patience, the courage and the allocation of time for this, you will succeed perfectly. We are not telling you how to put your phone back together, just follow the instructions in reverse order.
If you could not carry out a replacement, you always have the opportunity to call a professional service department, for example, a service center for the repair of mobile devices "MakeApple", which specializes specifically in the repair and restoration work and maintenance of iPhones.
The most common problem of breakage of iPhones, as well as other mobile phones, is gadgets flooded with various liquids, when moisture penetrates inside. In such a situation, it is generally not worthwhile to carry out repairs on your own, or expect a miracle that everything will dry up on its own and the iphone will work on its own.
The easiest breakdown is from flooding with any liquid, this will close the controller (after drying, the device can work, but the battery is quickly discharged). 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, if you are faced with a problem, when you doubt that you will fix the problem, it is best to contact the knowledgeable specialists of the service center. "MakeApple" (link above), where you can always turn for professional support and free advice.
The process of separating alcohol from the wash is called - distillation or alcohol stripping process. (article for persons +18!) Almost all of Apple's new phones are bestsellers. They are very popular and have won the hearts of most consumers forever. These gadgets are very reliable, functional and convenient. Contrary to their qualities, all iPhones, like all other smartphones, can break. More often the consumer is to blame. In a large number of cases, you can repair the iPhone with your own hands, but it is better to contact the service center specialists. Apple-Restore , they can use the new service for calling an Apple technician repairman to your home, work or other place convenient for you for free. There are not so many main reasons for iPhone breakdowns.These are breakdowns related to software (programs close by themselves, the phone “thinks” for a long time), which occurs if there was an intervention in the base platform or an incorrect installation of an 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 finally 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 the ingress of liquid on the iPhone 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 touch panel as a result of dropping the phone to the floor or asphalt. This breakdown can be corrected by yourself and not contact the service center, paying large repair bills. So, first you need to unscrew the two bolts, which are located at the edges of the cable connector. Then you should carefully remove the top panel together with the display. This can be done with a regular suction cup or pry off the edge. There are still small bolts from the end of the removed panel, which should also be unscrewed on both sides. There is another bolt next to the train, which must not be forgotten to unscrew. Thus, the display cable and touchscreen were disconnected. Now the display with the metal frame needs to 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 warm it up around the entire perimeter. After this procedure, the touchscreen must be detached from the frame with a scalpel. Next, you need to take double-sided thin tape and glue it around the perimeter to the panel body. The new touchscreen must be glued to the 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 touched and damaged, the repair of which will result in a tidy sum. Here is a video instruction for self-repairing iPhone 5. Select your device and see how to disassemble the phone and correctly 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 identified, you can buy all the necessary spare parts in our store. They are of high quality and original. Do-it-yourself iPhone 5 repair can be done without any problems. Before making repairs with your own hands, you will need to identify the damaged part. The Telemama service center has been selling spare parts, repairing equipment for a very long time. You will not be able to fix every breakdown on your own. If you want the repairs to be performed efficiently, not expensively and quickly, come to the Telemama service. Diagnostics are carried out here free of charge. To view all prices, you need to look at the price list. 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 company was created. Not the least factor in the whole 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 contact service centers due to a factory defect, since it is almost completely absent. If the creators reacted to the production of the iPhone very responsibly, then not every user can boast of careful use of the phone. Therefore, breakdowns occur quite often (through the fault of the buyer). In service centers, breakdowns such as broken touchscreens and moisture inside the phone are most often recorded. Such a disaster 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. Craftsmen who know a little about the Internet think that they will resurrect their phone with the help of search engines and numerous forums. Nobody can become a professional just by typing the phrase "repairing an iPhone". The iPhone is a complicated technique, therefore, along the way, the positive and negative sides of the “handyman at home” begin to emerge. The main advantage of home renovation is that it is completely free (if the owner is able to cope with the task at hand). In most cases, in practice, it turns out that later, after such repair work, you have to pay a larger amount than that which was originally supposed. The most common mistake is replacing the touchscreen 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 succeed in replacing the screen, but how long it will last will be known only along the way. After independent interventions, you will only have to believe that this period will be as long as possible. And most importantly, after home repairs, the factory warranty will no longer 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 repairmen”, after which even the service center will not be able to help the device. But I would like to clarify that there are 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 the repair of an iPhone to knowledgeable people. While you can try if you are a risk-taker, remember that you can end up paying a lot of money as a result.

An abundance of video materials on DIY iPhone repair, laid out in the public domain on the world wide web, often encourages smartphone owners to start repairing them on their own. Watching any video in which the wizards replace the power and go to the desktop buttons, eliminate various other problems, users try to keep up with every movement after the service engineers.At the same time, they do not always realize that such educational videos are laid out on the network, first of all, not for ordinary users, but for specialists with practical experience in restoring the device's working capacity. Why DIY iPhone repair does more harm than good Desire to fulfill DIY iPhone 6 plus, 5s, 4s repair most often begins to visit smartphone owners after visiting one or several 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 with 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 careless use, an expensive device can fail for a long time. To bring your broken device back to life, you will most likely need iphone repair. Only in no case should you try to bring the gadget back to life on your own, as this is fraught with the final breakdown of the device. It is much better to apply for this service to a professional service center, especially since such firms, due to the wide popularity of Apple products, are in every major city. To fully restore the functioning of the iphone, repairs must be carried out after preliminary diagnostics, which will reveal the scale and cost of restoration work. To restore the functionality of the "apple" smartphone, the following types of work can be performed: IPhone repair in terms of 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 1,500 rubles. Some service centers, trying to attract more customers, dump (offer prices for services significantly lower than market prices). But it is not recommended to use the services of such firms, since the quality of repairs in them leaves much to be desired. And instead of a repaired gadget, you can only get wasted money and a non-working smartphone. It has been said a thousand times: do not self-medicate, but still there are people who think that there is nothing difficult in repairing an iPhone. The Internet is replete with 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 with a screwdriver begins to consider themselves an electronic repair engineer, which is not the case. Further more: And there are more and more such customers "samproval", and, if in the case of the iPhone, you can get by with the replacement of the main board, which is quite expensive in comparison with the cost of an iPhone, then replacing the motherboard of a MacBook is at a price equal to the cost of a used computer. Trust the professionals, and you shouldn't save on repairing rather expensive Apple digital equipment if you want to continue using your gadget, being sure that it won't let you down at the most inopportune moment, for example, on the way to the airport. Engineers of Apple Service will repair your iPhone with high quality and with a guarantee for work performed and replaced parts, in compliance with all service procedures provided by Apple. Apple Blog: here you can find both useful information related to the repair of Apple computers, iPhone, iPod and iPad, and read about the curious cases that arise during the work of the service center. A question from a reader with the nickname himrus11: Hello! Is there a procedure to remove any minor scratches and abrasions without replacing the case? Redecoration, so to speak. The specialists of the ModMac service center answer: Hello! There are a lot of solutions here. Remember, the iPhone 5 was constantly erased edges, and many used a black marker to paint over them. The main thing is to choose the one that will not rub off - the method is probably also suitable for the iPhone 7. Scratches and scuffs, for example, on a Mac, can be tinted with a regular pencil, and some dirt can be easily removed with a regular eraser! In principle, you can do all this yourself, and if you want to restore the original look, you cannot do without replacing the case, alas. A question from a reader with the nickname chapaj1984: Hello! Problem with iPad, speaker wheezing and quiet, what could be? The specialists of the ModMac service center answer: Good day! Unfortunately, in recent years, this problem has begun to occur more and more often, both on the iPhone and iPad.Owners usually like to take their devices to the bathroom, where there is a high risk of moisture getting into open parts of the device, including through the speaker grill. Also, a blow, not even strong, could be the cause of this problem. In this case, only speaker replacement 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 keep in mind 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 malfunction of which must be corrected by a specialist, is not difficult DIY iPhone repair possible, although difficult to recommend to users. But, in life there are different circumstances and therefore, of course, it is impossible to exclude the fact that one day you will have to repair the iPhone yourself. Most of the work related to the elimination of smartphone breakdowns requires special skills, as well as the availability of expensive diagnostic and repair equipment, but such repairs as iphone display replacement the owner of a smartphone may well be produced if he shows due care. Damage to the iPhone screen is one of the most common causes of smartphone breakdown and anyone can face this problem. To produce DIY iPhone repair, you need to stock up on special tools. To replace the iPhone display, the kit will be minimal, but you still cannot 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 repair and improve your skills, it is better to purchase a set of screwdrivers for Apple appliances, 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 like this: First of all, you need to carefully unscrew the screws that secure the screen. They are located at the bottom and this task is not too difficult even for a beginner. You just need to be very careful not to damage the screw heads or scratch the smartphone case with a screwdriver. After that, using a suction cup, you need to lift the screen as carefully as possible, helping yourself with a plastic spatula. In the event that a broken iPhone display is being replaced, it is best to pre-stick an adhesive tape on the glass to avoid the part scattering 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 she who hides the connectors of the cables that connect the screen. After the plate is removed, very carefully, using tweezers, disconnect the connectors, all three pieces. That's all, we can assume that we have coped with this part of the work - the iPhone display is removed. Let's take a 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 greatest possible care, we separate this part of the button from the old screen, which, by the way, is very well glued: That's it - Home button removed without incident: Let's take care of the camera - it is fastened with two bolts: You also need to be very careful when removing the camera so that nothing is damaged or torn off. By the way, do not forget the plastic holder on the old screen, which also needs to be rearranged. Removing a metal plate When everything is cleared, you can start assembling and installing the new iPnone screen. Installation is carried out in the reverse order and, if you yourself removed the old screen, then installing a new one should not cause any difficulties. But, I would like to remind once again that accuracy when DIY iPhone repair, is in the first place, because if something goes wrong, it may become necessary to purchase a new part and unforeseen expenses.Only perform self-repair iPhone if you are confident in your abilities, otherwise, have Apple repair professional.

But such self-confidence does not always end with success. Moreover, with such clever 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 myself). The first step is to find out if 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 no longer fall under the factory warranty. If the iphone 5 is no longer covered by the warranty, as in my case, you need to determine whether the breakdown is of a software failure or hardware damage. Some faults can be fixed with the new firmware. If you have experience with flashing, in principle, you can do it yourself, but you need to check the serviceability of all cables, since interrupting the software update process can lead to irreversible damage, which has been shown more than once. But, nevertheless, it is better to entrust 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, resulting in 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 together with the glass. All three parts represent a single module that cannot be broken down 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 to look and function as if it had just been taken out of the factory box after the repair, it is necessary that only original spare parts are used when replacing parts. In reputable service centers, the client is provided with a certificate of authenticity of the part.
First, the obvious: how to disassemble the iPhone full of instructions, but how to put it back, there is practically no information. And the steps in reverse order are not always 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 to open the iPhone, but also requires an ESD protected workplace so that an accidental static electric discharge does not damage the electronic components on the motherboard in the smartphone.
The modern iPhone is the result of design and engineering ideas: huge functionality in a small package. A lot of screws of different sizes, which by the eye seem to be the same size, and the holes where the screws are screwed are of different depths.
Without knowing the nuances, such a would-be master will randomly screw in the screws, 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 fastening screws are screwed in, there are conductive paths connected just with the display. And this repairer, having screwed in a longer screw, damaged them. Rebuilding the conductive paths in the inner layers of the iPhone board is a rather expensive repair, more expensive than replacing a display module at an Apple service center.
