How to completely reinstall ios. How to reflash an iPhone using PC and iTunes

In this article we will look at ways to flash, restore and update an iPhone. Let's start with the fact that why is this necessary at all? Usually they re-ask the iPhone due to software errors or due to an unsuccessfully installed jailbreak. In general, the concept of flashing an iPhone differs from flashing the firmware of Android devices on an iPhone; this means restoring or updating the device, and in the future we will look at various ways providence for these operations.

iPhone flashing options

There are 2 processes involved in flashing an iOS device:

• recovery;
• update.

At their core, the processes are identical: in the first and second cases, as a result of flashing the iPhone, new iOS. Moreover, the concept of “new” in the case of restoring an iPhone does not refer to the version of the operating system, but to its state, in other words, “clean”.

iPhone flashing methods

You can reflash your iPhone in 2 ways, one of them is universal, i.e. used for both recovery and update, the second one is only for update:

• iPhone firmware via iTunes;
• Update iOS on iPhone via Wi-Fi.

In the first case, the software is downloaded to the computer and, using the iTunes media combiner, it is downloaded directly to the iOS device. Valid for iOS 4.3.5 inclusive. For iOS 5 and higher, the second method is possible, which involves updating iOS directly from the device via the Internet. wireless network(Wi-Fi).

What is the difference between restoring an iPhone and updating it?

As we have already said, restoring or updating an iPhone refers specifically to the software component of the device.

Restoring an iPhone is the process of restoring the device to its original settings. When restoring your iPhone, all content (photos, videos, music) and personal data will be deleted ( phone book, calendar information), the device settings will be reset to factory settings.

In a nutshell, restoring an iPhone is resetting the device to its factory state and installing a “clean” iOS of the latest version.

Updating an iPhone refers to the process of moving from an older version of iOS to a newer one. As a result of the update, all content, personal data and settings will remain intact and iOS will be updated to the new version.

As you can see, the fundamental difference between restoring and updating an iPhone is only that as a result of the update, content and personal data are not deleted from the Phone.

The result is:

Restoring iPhone = Delete Content + Factory Reset + iOS Update

As you know, the iPhone, like any other iOS device, can be in several modes provided by the manufacturer: normal mode, recovery mode ( Recovery Mode) and firmware update mode (DFU Mode).

It is possible to restore or update an iPhone in the following modes:

• V normal mode;
• in Recovery Mode;
• in DFU mode.

How to restore iPhone via iTunes?

In order to restore an iPhone via iTunes we will need:

• last iTunes version(preferably). At the time of writing, iTunes 11.1.5.5 is current. ;
• a pre-downloaded file with the version of iOS that is in currently installed on iPhone (optional).

So, let's assume you have the latest version of iTunes installed on your computer and you have downloaded the firmware file for your iPhone model to HDD.

• If Find My iPhone is enabled on your iPhone, turn it off in your device's settings;
• Connect your iPhone to your computer using a USB cable and if iTunes settings not specified automatic start programs when connecting an iOS device, launch iTunes;
• Go to the device synchronization settings page with iTunes by clicking on the button with the name of the device type in the right top corner next to the "iTunes Store" button;
• While holding down the "Shift" key on your keyboard, click on the "Restore" button (for Mac, you need to press the Alt+Restore button). A window for selecting a firmware file from the local disk will appear;
• Select the previously downloaded firmware file with the extension ".ipsw" and click on the "Open" button. Confirm the request to restore your iPhone. iTunes initiates the recovery process. No further action is required from you, iTunes will automatically delete all content and load the “fresh” firmware into the internal iPhone memory. In this case, the device will be switched to Recovery Mode and the device will be restored to its factory state.

It is important to know

The iPhone recovery process can be completely entrusted to iTunes, and there is no need to download the firmware file to your hard drive, however, after such a recovery, if more latest version iOS, it will be installed on the iPhone. In fact, content will be deleted, settings will be reset, and the iPhone will be updated to the new iOS.

How to restore iPhone from Recovery Mode and DFU Mode?

The procedure for restoring an iPhone from Recovery Mode or DFU Mode is completely identical, with one exception: before restoring, you must enter the iPhone into Recovery Mode or DFU Mode, respectively.

• Enter iPhone into Recovery Mode or DFU Mode;
• Connect your device to your computer using a USB cable and launch iTunes. The program will detect the iPhone in recovery mode;
• While holding down the "Shift" key on your keyboard, click on "Restore" ( Mac users press the combination "Alt+Restore");
• Open the previously downloaded firmware file with the extension ".ipsw". iTunes will take over the rest of the work, wait for the process to complete.

Is it possible to reset an iPhone without updating iOS?

If we are talking about a “clean” iPhone restore via iTunes, the result will be the latest version of iOS installed on the device, i.e. in fact, the firmware will be updated, and this is not always necessary, especially for owners of jailbroken devices. Why? Because a jailbreak for the current iPhone firmware version appears, as a rule, very late, and as a result, updating the iPhone will entail the loss of the jailbreak.

Restoring/Updating "locked" (locked under specific operator cellular communications) A jailbroken iPhone entails:

• blocking a “locked” iPhone - you will not be able to connect the device to the cellular network of another operator;
• loss of jailbreak.

Fortunately, there is a way to reset iPhone settings and remove all content from it without updating the iOS version and without losing the jailbreak. We have already talked about the SemiRestore utility, which allows you to clear the contents of an iOS device and reset its settings to factory settings without loss. Use the instructions if you have a “locked” or “jaybroken” device.

iPhone update

We have already mentioned that there are 2 ways to update an iOS device on latest version iOS:

• connected to a computer via iTunes;
• directly from your iOS device via Wi-Fi.

The first method is practically no different from restoring an iPhone to current version firmware. The second one allows you to update your iPhone to current iOS without connecting to a computer via Wi-Fi.

Updating iPhone from computer via iTunes

• Connect your iPhone to your computer using a USB cable and launch iTunes. Go to the "Devices" menu and select your device;
• On the page for setting up synchronization and settings for connecting the device to iTunes, left-click on “Update”. Confirm that your iPhone is updated to the latest one iOS version.
• You can save time and not wait iOS downloads to the office iTunes folder, after downloading the current iOS to your hard drive. Using the combination "Shift+Update" initiate a firmware update from the hard drive.

After the update, you will receive an iPhone with the latest iOS “on board”, all user content and settings will be saved.

Update iPhone over Wi-Fi

With the advent of iOS 5.0, developers integrated the ability to update firmware directly into the mobile operating system. Starting from iOS 5.0 and higher, the “Software Update” menu item is available in the settings of iOS devices. The update is only available when connected to the Internet via Wi-Fi. Bandwidth Internet connections from cellular networks do not allow updating iOS over a 2G or 3G connection.

• On iPhone, go to Settings -> General -> Software Update;
• Tap on “Download and install” and in the next window accept the terms of use. Wait for the process to complete.

Let us remind you once again that updating iOS does not entail the loss of user data and content and resetting settings, but it is dangerous for “jailbroken” and “locked” devices.

Firmware update for iPhone 4S involves the process of restoring its functionality. However, you need to know that all data will be lost during this operation. To do this, before flashing the firmware, you should make a backup copy (provided that the iPhone is in working condition).

Before implementation operational actions To flash an iPhone 4s, you need to download the firmware file using the extension - ipsw. The type of firmware will depend on certain version apparatus. To find suitable version firmware for iPhones, files will indicate all available versions, as well as device models.

In the process of choosing the appropriate firmware option, it happens that the models are difficult to find, which is due to the presence of modifications - CDMA, GSM iPhones. This is precisely what is a very important point when selecting the required model. When choosing a certain type of model, you will need to find a site to download the firmware. You should select the appropriate option and, if the choice is correct, carry out the OS download process. You can also select a new version of IOS, or download old firmware, which was earlier. The main condition is that the old version is signed by Apple.

The next step is to turn off the “Find iPhone” mode. This condition necessary to ensure a successful iPhone 4s flashing process, as enabled options may prevent this from happening. You should check for a new version of iTunes.

How to flash iPhone 4s

There are several ways to flash the iPhone 4s: via DFU mode and the second option is Recovery Mode. The second method is an emergency recovery mode and is intended for restoring the optimal performance of a device on IOS, in cases where the device stops operating under normal conditions. In DFU mode, all operational actions are carried out in addition to the iPhone OS and flashing directly through firware. This method suitable for those who own a device with Jailbreak, as well as in cases where it is not possible to carry out this operation with Recovery help Mode.

Flashing process using Recovery Mode:

• At the very beginning, you should disconnect your iPhone and connect it to your computer ( Home function), he will also recognize the device in the recovery Recovery mode Mode;

• connect the device to the computer and disconnect the device;
• with simultaneous pressing of the keys - “Home”, “Power” and count about ten seconds. Then you should release the “Power” button, and at the same time hold down “Home” until software system iTunes will not recognize an iPhone in DFU mode.

The order of operations in the recovery process is similar to Recovery Mode. This method is effective for those who have Jailbreak installed or the operation had no effect through Recovery Mode.

Flashing is performed when the new software program crashes very frequently with the presence of additional options and when the owner of the device changes. In such cases, this operation will need to be carried out with the built-in modem, as a result of which it will be blocked. The blockage is removed after the firmware is installed.

Flashing iPhone, iPod Touch via iTunes

After the restoration process, the iPhone 4s is configured by default, like a new device. You should select the previously downloaded IPSW file. IN Apple for iPhone, iPad, iPod touch, software called iOS. Firmware iOS device, is a recovery process or software update device, which consists of resetting the settings to the original (factory) level, with simultaneous IOS installation updated version.

Today, the iPhone occupies a leading position in the global market for sales of mobile devices. This is due to the presence of a large number technical capabilities, diverse functional features and service, providing the most various services. These devices are distinguished by very excellent quality and durability during operation. But over a certain period of time, the normal functioning of the device may cease and some errors may occur. Sometimes situations arise when the iPhone starts to reboot on its own or problems arise when Last update or new operating system, turn out to be unsuccessful.

The flashing process will provide working condition all functions of the device, thanks to which it will be able to serve for a very long time.

Currently, iPhone is the leader in the global sales market. mobile phones. This is due to its service features, great capabilities, variety of functions, options and services provided. This phone can boast high quality and many years of trouble-free operation. But nothing in this world lasts forever, including electronic equipment. Over time, the device stops functioning well, and some strange errors constantly pop up. Quite often, and for no apparent reason, the smartphone restarts. In addition, each user may encounter a problem when the latest personal update mobile device it turned out to be not very successful, or the new version of the operating system was not to your liking.

The problems listed above make you think and make a choice. Take the iPhone to a service center, where it will be 100% repaired, but you will have to pay quite a lot for it a large amount, or try to find a solution to the problem on your own by simply reflashing the gadget. The same method is most often used by service center specialists. There is no need to be afraid to carry out flashing on your own, since it is not as difficult and time-consuming as it seems at first glance.

Flashing an iPhone is restoring the phone to its original state. working condition. You should pay attention to the fact that flashing will lead to the loss of all information from the phone.

You should copy personal photos, videos, and audio materials to your hard drive, because flashing the device will result in it returning to factory settings and being completely clean.

You should also take into account the fact that regardless of the iPhone variation, be it 3, 4s or 5s, the flashing procedure is carried out identically in all cases. Therefore, you don’t need to worry about the instructions not matching your phone, you just need to carefully and clearly follow the steps described.

Below we will discuss in detail the firmware procedure for iPhone example 4s.

Preparatory actions

Even before starting the operation in question, the subscriber needs to download the firmware with the .ipsw extension. For a certain model iPhone has a version corresponding to it.

It is very easy to determine which version is needed for a particular smartphone. The firmware files contain the device version (iPhone 3, 4s, 6), as well as its model itself, which is an alphanumeric combination located on the back of the gadget below the logo.

The main difficulty in selecting the firmware version according to the model is that there are GSM and CDMA models of Apple devices. Their difference lies in the fact that these devices operate in different cellular networks. Firmware for GSM iPhone 4s will not work for iPhone 4s on CDMA.

After determining the model of your personal device, you need to download necessary firmware. Each subscriber can choose the latest version of iOS, or, if he doesn’t like it, he can download a slightly outdated one that was previously on the smartphone. The main condition is that old version, which is being downloaded again, was signed by Apple.

Also, before updating, the subscriber must turn off the option called “Find iPhone”. Otherwise, it will not be possible to reflash iPhone 4s, since this function interferes with the procedure in question, therefore, iTunes will throw an error.

In addition, it is better to make sure once again that the most updated software is installed on your smartphone. a new version iTunes, for this you just need to launch the program. If a new version is available, the program will automatically notify you about it and will be able to update. Having completed all the preparatory steps, you can safely proceed to the flashing process itself.

Flashing procedure

In general, to solve the problem in question, iPhone 4s owners are offered two options, each of which is absolutely valid, effective, and also allows you to restore your smartphone quite easily and quickly:

1. With help
2. Via DFUmode.

The first option is emergency mode recovery. Most often, it is used to restore the functionality of iOS gadgets after the moment when their proper functioning began to fail.

The second method is practically no different from the first. The only difference is that the procedure is carried out directly using firmware, bypassing the iPhone operating system. Often this method used when the device is jailbroken or when flashing using the first method is impossible.

Flashing using RecoveryMode

To carry out the operation using this method, the subscriber should turn off the iPhone and wait until the smartphone screen goes completely dark. Then you need to connect it to the computer while holding the Home button. The PC will accept the device in mode Recovery Mode.

Subsequent steps must be performed in this order.

You need to launch iTunes and wait until the program finds the iPhone; there are two options:

• iTunes will prompt the user to restore the connected device. In this case, click OK.

• iTunes is completely unresponsive. Then you should click on the phone icon, find the item called "", after which you need to select it while holding down the Shift button (if you are using the operating system Windows system) or Alt (when using the Mac operating system).

Next, the File Manager will open, where the subscriber will need to select the firmware. You need to find a file that contains the firmware downloaded before the operation began. Then you need to select it and click the “Open” button.

After this, the program will do everything on its own; you just need to wait for the process to complete. Once completed, the device must be disconnected from the computer. Then you need to turn off the phone by holding Power button. After that, by pressing the same button again, you need to turn on the smartphone. That's all, absolutely all iPhone settings have been corrected, and it is ready for further use.

Flashing using DFUmode

Even before the process under consideration begins, the smartphone must be switched to DFUmode. Then you need to connect the phone to the computer and turn it off. After this, on the device you must simultaneously hold down Home buttons, as well as Power and count ten seconds, after which the Power key must be released and Home must continue to be held until the iTunes program recognizes the smartphone being configured in DFU mode.

Subsequent actions must be performed in strict sequence, and they are almost completely identical, as in the case of RecoveryMode:

1. First you need to select the required device in the program.
2. In the phone manual menu, you need to find the “Restore iPhone” item.
3. After that, you need to select it by pressing the Shift button (if you are using the Windows operating system) or Alt (when you are using the Mac operating system).
4. In the window that opens as a result, you need to specify the path to the file with the previously downloaded firmware, and then click on the “Open” button.
5. After completing the actions, the subscriber needs to wait until the program completes the ongoing procedure.
6. All that remains is to turn on the restored smartphone, after which you can use it absolutely calmly and confidently. working iPhone 4s.

The considered solution to the problem will be useful to those subscribers who installed Jailbreak on their own device, or due to certain reasons, flashing it in RecoveryMode did not lead to success.

Each of the flashing options considered is absolutely valid and should help solve the problem in question. The subscriber does not need to be afraid to independently carry out this process, since there is nothing complicated about it. You just need to have the slightest skills in using a smartphone and be extremely careful. Actions must be performed in strict sequence, and then a successful ending is guaranteed. The main advantage of the process is that there is no need to spend any cash how would this happen in service center. Despite this, the person receives the phone in almost no time. worst settings, which are provided by the gadget service center. But if you still doubt your abilities, or for some reason you were unable to cope with your goal, then it is better to apply for professional help or at least consultation with specialists. This can be done in almost every district of any city in the country.

Hi all! Recovery theme iOS firmware has long been reviewed on the Internet up and down. And, to be honest, at first I didn’t want to write about something that was already online. Why produce the same type of instructions? But then it was finally decided (such is the agony of choice for the author of this blog! :)) that there was a need for this.

So why another instruction? Everything is very simple - I receive a lot of questions, both by email and in the comments, about various failures in the software securing iPhone and, in most cases, they can only be cured through software recovery. So this process is important and there is no way to bypass it, and it will be easier for me to answer your questions by simply pointing out a link to this article. Eh, looks like it was justified :) Let's go!

A few important notes:

1. When you restore an iPhone, absolutely everything is deleted from it. It turns out that the phone looks like you just bought it in a store.
2. You can only restore using a computer and iTunes programs. This cannot be done over the air, via iCloud or any other way.
3. The procedure is performed both when the device is fully operational, and if iOS system does not load (in this case you will need to enter DFU mode).

By the way, recovery is the only way Correctly remove jailbreak from iPhone.

Detailed instructions for restoring iPhone

So, complete and detailed step-by-step instruction. We launch iTunes on the computer and connect the iPhone, if everything went well, then the phone model, its firmware and other data will be displayed in the main program window. On at this stage two errors are possible:

1. The computer does not detect the iPhone - about this.
2. If the device shows no signs of life, we try.

As a result, with any successful connection we get one of two windows

And here we are interested in only one button - “Restore”. If you just click on it, iTunes will begin to prepare the iPhone, download the latest current firmware from Apple servers and will begin installing it on your device.

Attention! Find My iPhone must be disabled!

The biggest “catch” is loading the firmware. Sometimes this process takes quite a lot a large number of time, especially with slow Internet. Plus, if the connection is not stable and the connection is possible, then iTunes will start downloading it again every time, which you will agree is not very pleasant and time-consuming.

But there is a way to speed up the recovery process. To do this, you need to download the software file in .ipsw format yourself (from any third party resource, for example w3bsit3-dns.com) and save it on your computer. Please note - each iPhone model will have its own file, different from others!

Now, hold down the “Shift” key on the keyboard and only then click on the “Restore” button. A window will open asking you to specify the firmware file. We select the pre-downloaded one and wait - iTunes will do everything on its own.

Why can't I restore my iPhone and what should I do?

In fact, there can be a lot of reasons. Moreover, they are associated both with a computer or device, and simply with inattention.

Here are the most basic ones:

1. Lack of Internet access on the PC or periodic interruptions and shutdowns.
2. Antiviruses, firewalls and other interfering programs normal functioning iTunes. Perhaps your security settings are configured in such a way that iTunes simply does not gain access to Apple servers.
3. Slow Internet connection. Not even that. Very Slow internet. This is rare now, but I remember my attempts to revive an iPhone back in 2009 using a network connection from a USB modem. I won’t describe everything, but I’ll say the result - the restoration failed.
4. In the case when you download the firmware yourself, see if it is exactly suitable for your specific phone model.
5. Check for iTunes. If yes, install the latest version of the program.
6. It is very advisable, and what’s more, be sure to use an original USB cable, non-certified ones can contribute to the appearance various errors. Non-original ones are only possible, and even then not always, and they are not suitable for flashing (restoring).
7. It is quite possible that the problems are already inside, that is, “iron”. There can be a lot of malfunctions - from the cable to motherboard. Remember, not or too much.

As you can see, there are really a lot of options. Please pay attention to every little thing - because it is precisely because of this that problems may arise. iPhone restoration. Something still doesn't work out? Be sure to write in the comments - we’ll try to figure it out together!

P.S. They say that in order for the recovery to be successful and correct, you need to “like” this article. They're probably lying, but I installed it just in case... and it worked! :)

When trying to figure out how to flash an iPhone, the user must first understand what firmware is and what flashing methods exist. The process itself takes 10 minutes and anyone can do it. iPhone owner, but for greater confidence you need to know some technical points.

We already wrote instructions on the website on how to reflash an iPhone, but we were talking about iPhones 4 and 5. You can look at this article. In general, the process remained the same. Below we tell you how to reflash iPhones modern versions(iPhones 6 and 7) and how to install an iOS update on an iPhone 6 or 7.

Firmware options and methods

iPhone firmware is its software, the operating system known as iOS. Flashing is a system restoration or update. In the first case, it means returning to factory settings with deleting personal data, in the second, installing a new version of iOS without affecting user content.

Reflashing may be required in the following cases:

• iOS malfunctions.
• Release of a new version of iOS.
• Necessity complete removal information from the phone - for example, when transferring the device to another owner.

There are two methods iPhone flashing: Via connection to iTunes and via Wi-Fi. In iTunes, you can perform both firmware options, recovery and update. Via Wi-Fi, only device upgrades are possible, that is, downloading and installing updates.

Apple doesn't allow installation outdated versions iOS. This does not prevent craftsmen from releasing software that allows you to downgrade the system version, but most often it only works on older ones iPhone models. There is no way to downgrade iOS on iPhone 6 or 7.

Recovery via iTunes

Before you begin recovery, think about whether you are prepared to lose the data stored on your phone. If not, be sure to make an up-to-date backup of your information. You can save it on your computer using iTunes, or send it to iCloud by syncing with cloud storage. If restoration, that is, a rollback to the factory state with simultaneous iOS update, is performed just for complete cleaning devices, then no backup copy will not need.

You can restore your smartphone in two modes, normal and DFU. The second method will be needed if errors appear in normal mode. But in any case, you should start with restoring to normal mode.

1. Open iCloud in Settings and turn off Find My iPhone.
2. Enter your Apple ID and password to confirm you can turn off the security feature.
3. Connect your device via USB to your PC and launch iTunes. Select your phone by clicking on the icon in the program window.
4. Click "Restore iPhone". iTunes will find and install the latest version of iOS. The recovery must not be interrupted; this will damage the system.

You can speed up the process by first downloading the firmware file in IPSW format. To select it, hold down the Shift key and click “Restore iPhone.” An explorer window will appear, through which you need to specify the path to the iPSW file.

Working in DFU mode

If in normal iPhone mode is not restored and iTunes gives an error, use DFU mode. The order will be as follows:

1. Open iCloud settings and turn off Find My iPhone.
2. Download the latest version of iOS to your computer.
3. Connect your iPhone to your computer. Press the Home and Power keys for 10-15 seconds until the screen goes blank. A second after the screen goes dark, release the Power button but continue to hold Home. Wait for iTunes to notify you that your device has been detected in recovery mode.
4. Hold down the Shift key on your computer keyboard and click “Restore iPhone.”
5. Select the downloaded firmware file and wait for the recovery process to complete.

To exit the device from DFU mode, hold down the Power and Home buttons for 15 seconds.

There is no home button on the iPhone 7, so the order in which you enter and exit DFU mode will be slightly different:

1. Connect iPhone 7 to your computer.
2. Press and hold the Power button.
3. Without releasing the power button, hold down the volume down key. Hold both buttons for 10 seconds. If it appears Apple logo, repeat the procedure - this means that you held the buttons for too long.
4. After 10 seconds, release the Power button. Continue holding the Volume Down key for another 5 seconds. If the Connect to iTunes screen appears, start over - you've been holding down the buttons for too long.
5. If the display remains black and iTunes shows a message saying that it has detected a device in recovery mode, then you have put your iPhone into DFU mode.

Otherwise, the instructions are similar: you need to select an IPSW file or trust iTunes to download and install the firmware yourself. To wake your iPhone 7 from DFU mode, hold the Volume Down key and the Power button until the Apple logo appears.

iPhone update

We figured out how to reflash new iPhone, via iTunes – convenient way, but its implementation requires a computer at hand. If you don’t have a computer and need a new version of iOS, you can get it via Wi-Fi. Why only Wi-Fi and not mobile traffic? The answer lies in the size of the downloaded file. 3G bandwidth does not allow for normal downloading of such volumes of information, so you have to use a Wi-Fi connection.

1. Connect your phone to Wi-Fi.
2. Open the "General" section in Settings. Go to the “Software Update” submenu.
3. It will start checking for updates. If there are updates, the “Download and Install” button will appear.

Important: updating via Wi-Fi cannot be used on jailbroken phones, this will lead to an “eternal apple”. How can you tell if your device is jailbroken? The Cydia application will be available on it.

You can also update iOS through iTunes, and the procedure for performing the operation will be practically no different from restoring the device, with the only exception - user content will remain untouched.

1. Launch iTunes, connect your device and select it in the program window.
2. Click "Update" and confirm the operation.

You can download the latest version of iOS to your computer yourself, and then select the firmware file in iTunes. This approach will save time on downloading updated version systems. To be able to specify the path to the firmware file, hold down the Shift key and click “Update”. An explorer window will appear in which you can select the downloaded upgrade.

Remember: user content and settings are preserved when updating. If you restore the device, the phone will become “clean”, as it was after purchase.
