iPhone firmware or how to restore iOS via iTunes. Troubleshooting iPhone recovery errors

After changing iPhone 7/6/5 to the new top model iPhone 10, many users wondered how to quickly transfer data from an old iPhone to a new one. Of course, the most common way for everyone is to back up all data on one device and then restore it on another. This can be done through iTunes or iCloud. However, not everyone succeeded: some “users” report that the iPhone is not restored from a backup. Why this happens and how to restore data from a backup copy will be described in detail below.

Can't restore iPhone X from backup

So, let's figure out why users are unable to restore data to iPhone X from a backup made on the old one. In order to transfer all data from iPhone 7 to iPhone 10, you must first backup all information on your old iPhone.

How to Recover Data on iPhone X from iPhone 7/7 Plus Backup

This can be done through iTunes by connecting the device using a USB cable and selecting the appropriate function in the program window. Or backup can be done via iCloud. To do this, open the application on iPhone 7 Settings – Accounts and Passwords –iCloud – Backup toiCloud, activate the slider and click Create a backup.

After this, when activating your iPhone, you just have to select the option to restore from iTunes/iCloud backup and wait until the process is completed. If iPhone is not restored from iPhone backup, then something went wrong.

I can't restore from a backup via iTunes

The most important condition for successful recovery is the absence of a conflict between operating systems. The phone has the new iOS 11 platform installed. If the device has an operating system lower than iOS 11.2/11.1 (for example, iOS 10 or iOS 10.2, etc.), then you will not be able to restore the device from a backup. It is necessary that both devices have iOS 11 installed, but the firmware version is not important. Then do the following:

1. Update your iPhone to the latest iOS 11 firmware.

2. Back up all your data again via iTunes or iCloud (whichever is convenient for you).

3. After this, restore from the backup on your iPhone, specifying the latest backup file.

How to Recover Data on iPhone X from iPhone 7 Backup Using UltData

If you still cannot restore your device from a backup in the standard way, then you can use the program. It is designed to recover deleted and lost data and allows you to use three different methods. In our case, we can use only two methods - restore from an iTunes or iCloud backup file.

1. Back up all your data to iTunes or iCloud, whichever is convenient for you.

2. Download the UltData program to your computer, install and run. Then connect your iPhone using a cable to your computer.

3. In the program window that opens, select “Recover from iTunes Backup Files” if you backed up your iPhone 7 using iTunes. Select the last one from the list of backup files, which you just did in the first step. Select and click on the scan button.

4. Once the scan is complete, you will be asked to select the desired file types with a preview option.

5. Select and click on the restore button. All files will be automatically saved to your new device.

The advantage of using the UltData program is the ability to restore not all data from a backup copy, but selectively - only those that are needed. You can use the tool on both Mac and Windows. You can also use the utility to recover accidentally deleted files.

Each user of Apple products, when creating an Apple ID, receives 5 GB in the iCloud cloud for permanent use. This space is mainly used to automatically create backups from mobile devices. At any point in time, after resetting the settings, the user can use it to restore the iPhone.

The only drawback of this method is the need to use Wi-Fi, since it is impossible to perform this operation using a cellular network. If the wireless connection is unavailable or unstable for some reason, you will have to use a computer. How to restore an iPhone via iTunes and what is required for this, you will learn from this material.

Backup using iCloud does not require additional actions from the iPhone owner. A smartphone placed on charge and within range of a Wi-Fi network will automatically save data. Creating a local copy requires that you first set up pairing with iTunes.

We launch the program on the PC and click on the icon with a miniature of the mobile device, indicated by an arrow. Select the device for which local copying will be performed.

Mark the item indicated by the arrow. The frame in the screenshot indicates the list of copies previously created for the selected device.

The privacy policy requires additional encryption of the user's personal data. This ensures the safety of email accounts, passwords and accounts created during registration on various Internet resources. If you do not immediately check the box marked with an arrow, the program will remind you of the need for protection at the next stage. To start the copying process, press the virtual button indicated by the frame.

When the encryption item is not selected in the previous step, the warning shown in the screenshot appears. If you check the box marked with an arrow in the pop-up window, the program will stop asking this question in the future. Presses the marked button to maintain confidential copy mode.

In the input fields, set the security password and confirm it. The check mark indicated by the arrow is intended for saving it in the cloud. Now, even if you forget your password, you can find it in the Keychain Access app on Mac computers.

Having completed the preparatory operations, we create a local backup copy. The progress is indicated by an indicator strip marked with the number “1”. The two shows the pairing icon. After copying is complete, the “ring” will stop rotating and will be replaced by the standard device shutdown icon. The frame indicates an item that, when turned on, allows you to copy without connecting your smartphone via USB.

You can use the created local copy with more than just one device. For example, you can buy a 5 SE and restore data from an old 4S on it. The main thing is that the amount of internal memory on the new device is greater than on the old one or equal to it.

Search function

All Apple products include a device locator feature in case it's lost or stolen. It works equally on iPhone 6 and iPhone X, as well as on intermediate models with S and SE indexes. The smartphone is linked using the Apple ID. As a result, you can activate the search mode from another Apple device or by connecting to iCloud through a browser.

When creating a copy, the state of this service does not matter; you only need to disable it for recovery. This must also be done when the device is sent in for repair to replace components. When transferring or selling, unlinking your smartphone from your Apple ID, you disable it automatically. If you don't do this, devices running iOS 10 and higher will experience Activation Lock and will be unable to use your iPhone.

Open settings on your smartphone. At the top of the window, in the area indicated by a frame, parameters related to Apple ID and branded services are concentrated. Expand the internal menu of this item.

At the bottom of the screen, after the main services, there is a list of devices linked to an Apple ID. Select your iPhone in it.

Immediately below the device name is the item we need, indicated by a frame in the screenshot.

Move the slider in the marked area to the “Off” position.

We confirm the decision by entering the account password in the field indicated by the arrow.

Reset settings

Before performing the recovery procedure, let's return the iPhone to its original state by performing a factory reset.

We return to the main settings page. Select the “Basic” section shown in the screenshot.

Scroll down the screen to the very end. The penultimate item, indicated by a frame, contains various reset options.

Select full erase. As a result, all photos, contacts, programs and other traces of using the smartphone should be deleted.

First, the system will offer to update the copy of the data in the cloud. This will not be superfluous even if you have data locally saved using iTunes.

Recovery

When applied to the iPhone, the term “recovery” cannot be taken literally. It does not relate to the software and version of the operating system, but to the overall performance of the device. The backup copy, no matter whether it is created locally or in the cloud, contains only user data, but not the firmware.

We connect the iPhone to the computer using a USB cable. iTunes recognizes your smartphone. When automatic synchronization is configured, the backup will update itself. Otherwise, first press the button marked “1”. The data in the local file will be replaced with the current ones manually. After this operation is completed, the virtual button marked “2” in the screenshot will become active. Click on it to start the recovery procedure.

If at some point you forgot to turn off the search function, the system will politely remind you about it.

The following popup window contains a selection dialog. Using the field indicated by an arrow, you can select the copy to be used. This does not have to be data from the connected device. You can also select previously saved data from another Apple smartphone.

Recovery with iOS update

If the firmware on your smartphone has not been updated for a long time, the recovery procedure may not work. In this case, iTunes will display a message stating that outdated software does not allow the operation to complete.

Disconnect the iPhone from the computer and close the program. After making sure that the latest version of iTunes is installed, launch it again. We connect the smartphone to the PC with a USB cable. Select the item marked in the screenshot to force a firmware update.

iTunes will download the latest version of iOS compatible with your device and install it automatically. At the initial setup stage, select the item marked in the screenshot. We restore from a saved local copy.

Forced recovery mode

Device Firmware Update or DFU for short is a forced firmware mode on Apple smartphones and tablets. With it, you can restore your device even if it stops turning on or is not recognized by iTunes.

To work with an iPhone in this mode, connect it via the USB port and perform a forced reboot:
- For 2017 models (8, 8 Plus, X), you need to quickly press the volume up key once, then press the volume down key. Lastly, press and hold the power button.
- On iPhone 7, 7 Plus, simultaneously press and hold the volume down and power keys.
- On all other models, the power and home buttons are simultaneously pressed and held.

As a result of these actions, the iTunes and connecting cable logos should appear on the screen.

At the same time, the window shown in the screenshot will appear on the computer. Click on the designated button, allowing iTunes to search and download the latest version of iOS compatible with the device. How long the download will take depends on the speed of the connection you are using. After installing the latest version of the OS, the device will start in normal mode. Now you can use a previously made local copy for configuration.

If the operation takes more than 15 minutes, the smartphone will automatically exit DFU mode. In this case, we repeat the described steps until the firmware is completed.

In conclusion

With all the advantages of wireless technologies and cloud storage, restoring using iTunes is the only way to bring your iPhone back to life in the event of a serious failure. Not every user may encounter such a need, but knowledge is never superfluous, especially in critical situations.

Video instructions

More information about recovery methods using iTunes can be found in the overview video below.

When restoring an iPhone, iTunes sometimes gives an unknown error with a number, without correcting which it is impossible to continue working with the mobile device. Depending on the number of the problem that prevented you from restoring your iPhone, there are different ways to fix the problem.

Error classification

Apple support on a special page on the website divides failures by number into several categories. However, you will not find some codes. For example, there is no number 52 on the support page, because iTunes does not crash with such a code. Error 47 is also not listed, although some users complain that due to a glitch with this number they are unable to restore their iPhone.

If you encounter problem 47, there may be several reasons for its occurrence:

Failure of the modem chip.
Modem processor failure.
Liquid has entered the modem part.

As you can see, error 47 is due to a hardware problem. Therefore, if you encounter failure 47 when restoring your iPhone, take your mobile device to a service center. Even the master does not immediately determine the exact cause problem number 47 appears, so it’s better not to risk trying to repair it yourself.

Communication errors (1671, 3004, 3014, 3194)

If, when restoring an iPhone, iTunes displays a message with numbers 1671, 3004, 3014, 3194 or 9006, then you are dealing with problems that are preventing your computer from establishing a connection with the Apple server or mobile device. If problems 3004, 3014, 3194, 9006 occur, first try restarting your computer. If this does not help, close the applications that are running in the background, leaving only iTunes. Disable your firewall and antivirus. Since failures with numbers 3004, 3014 3194, 9006 occur due to the inability to establish a connection to the server, disabling the firewall will help remove the firewall.

If these methods do not help get rid of failures 3004, 3014, 3194, 9006, then try the following methods:

The extra entry will end with gs.apple.com. If you find one, delete it immediately and save the hosts file. After editing hosts, error messages 3004, 3014, 3194, 9006 should no longer appear when restoring an iPhone. If problems with numbers 3004, 3014 3194, 9006 appear when restoring an iPhone on a Mac computer, then open hosts through the terminal using the command “sudo nano /private/etc/hosts”.

If iTunes displays error 3194 when the recovery line is 2/3 full, then most likely you are faced with a hardware problem - damage to the modem or iPhone power module.

If you cannot restore your device due to problems with the modem, contact a service center for help, as you will not be able to fix the problem yourself.

Errors 14 and 4005

Failures with numbers 14 and 4005 when restoring an iPhone usually occur when problems are detected with connecting the device via USB. Error 14 indicates that during the recovery process, iTunes detected a violation of the integrity of the firmware file. Error 4005 usually indicates that there is some problem with the cable or port on the computer.

To fix error 14 or 4005:

Use the original iPhone cable.
Connect the device to a different port. Try to use connectors that are located on the rear panel of the system unit, then you will have less chance of errors like 14 and 4005 appearing.
Connect your iPhone to another computer.

If error 14 or 4005 persists, try putting your phone into DFU mode before restoring. If this does not help resolve failure 14 or 4005, download the firmware manually and select the desired ipsw file by holding down the Shift key while clicking the “Restore” button.

Errors numbered 14 and 4005 appear when you try to update the firmware by jumping through the version (for example, from iOS 7 directly to iOS 9). To avoid issue 14 or 4005, select the appropriate firmware version.

Error 21

Failure number 21 occurs when the device is incorrectly entered into DFU mode. To eliminate the cause of error 21, use programs like redsn0w to transfer the phone to DFU.

Owners of iPhones that have been jailbroken especially frequently encounter crash 21. In addition, failure 21 may occur due to the fact that the battery is not fully charged. Accordingly, to fix problem number 21, you need to put your smartphone on charge.

Unsuccessful firmware or jailbreak of the device can lead to malfunction. In this case, there is no need to despair; you just need to restore your iPhone using iTunes. The procedure is simple and takes little time, however, you need to know some features, which we will discuss in this instruction.

Determine which version of iOS you can restore to

Before you begin restoring your iPhone, you must determine which version of iOS is suitable for the device. The fact is that when releasing new versions of iOS, Apple stops signing old builds. Restoring and rolling back to them, accordingly, becomes impossible.

The easiest way to determine which version of iOS you can restore to is using this service. Follow the link and select the model of your iPhone (or other Apple mobile device). Firmware marked with checkmarks can be restored. It will not be possible to restore iOS builds marked with crosses. On the same site you can download the firmware itself, which is necessary for recovery.

Step 1. Download the latest version of iTunes from the official website or update the already installed program. On a Mac, you can check for updates in the Mac App Store; on Windows, in the " Reference» → « Updates».

Step 2. Download the firmware version you need. You can download using this service.

Step 3: Connect your iPhone to your computer and enter it into recovery mode. To do this, simultaneously hold down the buttons Nutrition And Home for 10 seconds, then release the button Nutrition, continuing to hold Home for 6-9 seconds. If you did everything correctly, iTunes will launch with a message that the iPhone was found in recovery mode.

Note: Putting iPhone 7 and iPhone 7 Plus into recovery mode is slightly different. Instead of the Home button, you should hold the Volume Down button.

Step 4. Hold down the Shift key on your keyboard and while holding it click on the “ Restore" In the window that opens, select the previously downloaded firmware file.

Step 5: Confirm that the recovery will begin.

Step 6. The recovery process will start and after it is completed, the device will work normally.

During the recovery process, various errors may occur; let's look at some of them.

How to fix error 3194 when restoring iPhone

Error number 3194 can occur for various reasons, but the main one is the consequences of working with the TinyUmbrella or similar utility.

In order to get rid of error 3194 when restoring an iPhone, you need to do the following:

Open the folder C:\Windows\System32\Drivers\etc and find the file in it hosts.
Open the file using the standard program " Notebook" and find the line containing the inscription gs.apple.com- delete this line.
Save the file and restart your computer.

There is a high probability that error 3194 will not occur the next time you try to restore your iPhone. But for greater confidence, before starting the procedure, temporarily disable your computer’s firewall - the chances of successful recovery will increase significantly.

How to fix errors 1013, 1014 or 1015 when restoring iPhone

These errors occur when you try to downgrade the firmware due to the inability to downgrade the modem version. Important − This method will only help with older iPhone models (iPhone 4s and older).

In order to get rid of errors 1013, 1014 or 1015 during iPhone recovery, you need to do the following:

These instructions apply not only to the iPhone, but also to the iPad and iPod Touch. The main thing is to follow all the points exactly, after making sure that all precautionary rules are followed.

iPhone restoration is a standard operation to return an Apple smartphone to a working state after various failures. Unsuccessful firmware, incorrectly executed jailbreak, incorrect iOS update - if you know how to restore an iPhone, you can fix almost any problems that arise during the operation of this device.

Recovery procedure

To restore your iPhone, you need to enter Recovery Mode. It's easy to do:

When the iPhone is ready for the rollback and error correction procedure, click the “Restore” button.

iTunes will independently find the current firmware version and install it on the smartphone, returning it to the state in which it was immediately after purchase.

Working in DFU mode

If iPhone recovery does not work in Recovery Mode, then you need to enter the device into DFU mode. This mode is used when there are software errors - for example, when the iPhone does not turn on. DFU mode works at the hardware level, so it helps to reset all settings even in the most difficult cases. To enter DFU mode:

Connect your device to your computer.
Press and hold Power and Home for 10 seconds.
After counting to 10, release Power while continuing to hold the Home button.

It's difficult to enter DFU mode the first time because nothing changes on the screen. If the recovery mode detects itself as an iTunes icon, then the phone does not seem to turn on in DFU. Therefore, you need to look at the computer screen where iTunes is running. As soon as the iPhone enters DFU mode, a notification will appear in iTunes informing you that the program has detected the device in recovery mode, and you need to reset all settings and content to continue working with your smartphone.

If you need to install another firmware, hold down Shift and click “Restore”. An explorer will appear through which you need to specify the path to the previously downloaded firmware.

Recovery without a computer

If you don’t have your computer at hand, it won’t turn on, or you can’t connect your iPhone to it, then try resetting all settings through the device settings. As a result of this operation, you will get a clean smartphone without settings and user information, so be sure to make a backup before resetting. If the smartphone turns on normally:

It is not necessary to delete user files. If the iPhone turns on, then you can eliminate problems with its operation by simply resetting the settings. In this case, the user’s personal data will remain intact.

Recovery after reset

If you need to restore your iPhone after resetting all settings and deleting content, you won’t be able to do this without a backup copy. The presence of a backup file with information stored in the device’s memory is the main point that needs to be checked before performing a reset. After restoring the iPhone to its factory state, all personal data of the user is erased from it.

Creating a backup before resetting:

After the reset, the iPhone will be like new: no content or settings will remain on it. To get all the information back, you need to connect the device to your computer and restore from the backup via iTunes. Choose the most recent backup, as it stores the most current information.

You can also restore all settings after a reset via iCloud, provided that you stored backups on the cloud. In this case, when setting up your iPhone, you need to select the “Restore a copy from iCloud” option and specify a suitable backup.

Problems during recovery

If after a normal recovery the phone does not turn on, then it makes sense to put it in DFU mode and try restoring it through iTunes again. This time you should not trust iTunes: download the official firmware and select it in the Explorer window by holding Shift and clicking on the “Restore” button .

Sometimes the TinyUmbrella utility helps solve the problem that the smartphone does not turn on after resetting the settings via iTunes. This program has an “Exit Recovery” button. If the iPhone does not turn on after recovery, you need to select it in the TinyUmbrella window and click “Exit Recovery”.
