Checking the functionality of components

Due to the error “an invalid response was received from the device,” it becomes impossible to turn on iTunes, update the firmware, and set up phone backups. Before proceeding with specific actions in your OS, we recommend checking the following components:

  • Check the iTunes installed on your PC using an antivirus. If any errors or malicious utilities are detected, reinstall the software by downloading installation file from the official website of Apple Corporation;
  • Apple Mobile Device recognition may not work on your PC. Try installing iTunes on another computer and connecting again;
  • Problems with the USB connector may also cause the error. The phone connects to the PC, however, due to the lack of interface interaction, applications do not detect the device;
  • Cable. It may be faulty. Use another similar wire.

Connecting iPhone to PC for the first time

If you have not previously set up synchronization between your phone and your computer, you should add your PC to the list of “trusted” devices. The iPhone will make all subsequent connections automatically, and the “invalid response received from the device” error will no longer appear.

Immediately after connecting to USB, wait for the message shown in the figure to appear. Do not reject it, but click on “Continue”. Then wait until the synchronization completes. All settings will be configured automatically. It is the cancellation of this request causes problems to occur.

I absolutely welcome everyone! I have one computer, to which an iPhone or iPad is very rarely connected. Okay, stop. Just don’t think that the author is a wildly wealthy person. He owns a lot of hardware and is generally fattening with might and main... No. It’s just that this is my very first computer, it’s very old and it’s a shame to throw it away :)

So, a connection to this PC is required literally several times a year. And yesterday such a need arose - I needed to upload a couple of photos. With a practiced movement, I take the cable, insert one end into the USB port, the other into the iPhone, iTunes starts on the computer and... an error appears: “iTunes was unable to connect to the iPhone because an invalid response was received from the device.”

What nonsense? Just in case:

  1. I reboot the PC.
  2. I change the USB port.

Nothing changes - “iTunes could not connect” and even if you crack.

I went online to look for the reasons for the error and was horrified - some huge texts with a bunch of actions, you need to delete something, clean the registry, download additional programs... Damn, yes Windows is simpler reinstall! (Of course, I won’t do this © Sergey Glushko)

What to do then? Believe me, the error “iTunes could not connect to iPhone because an invalid response was received from the device” has a much simpler and fast decision. Here's what to do:

  • Update iTunes().

All. Nothing else is needed - the fact is that the cause of the error “an invalid response was received from the device” is a mismatch between the versions of iTunes, iOS, Mac OS (if you are using an Apple computer).

Actually, that’s what happened to me – iTunes was installed old version and he just didn't know how to work with new version iOS on my iPhone, so I was getting an invalid response from the device. But! In some, especially advanced cases, simple automatic update you won’t get away with it (simply because it may not go through correctly and some components will not be updated), which means everything will have to be done manually. Required:


Important note. Just in case, before connecting, you need to turn off antiviruses - some of their components can also interfere with the connection of the iOS device to the computer.

Now that's absolutely everything. As you can see, there is nothing complicated or supernatural – a couple of minutes and you’re done! After these manipulations, iTunes will finally be able to detect the iPhone, the response from the device will become valid, everyone is happy. Hooray! Victory!

If, when synchronizing your Apple gadget with iTunes, an error occurs indicating that an invalid iPhone response was received, we advise you to familiarize yourself with the proposed solutions to the problem.

  4. Reboot.

After this, the error “an invalid response was received from the device” iPhone should disappear.

Owners of Windows Vista and Windows 7

  1. Through Start, open the “Computer” window;
  2. In Folder Options, select “Show hidden files and folders”;
  3. In the Win7/Vista section, go to ProgramData, then find the Apple directory;

After the suggested actions, the error in the form “iTunes could not connect to iPhone” should be corrected.

Windows XP users

  1. Click "My Computer";
  2. Next “Tools” - “Folder Options” - “View”;
  3. Click on Extra options, find “Hidden files and folders”, in the “Show hidden files and folders” item, check the box and save these settings;

  5. Reboot the system.

The “invalid response from iPhone” window will no longer appear.

A window with the message “iTunes could not connect to this iPhone. An unknown error has occurred" appears when the Lockdown directory or its contents are corrupted. Solution - .

The error can also be caused by connection problems, Jailbreak, incorrectly installed/updated iTunes and antivirus protection Windows.

As a result, a window appears with the following messages:

  1. iTunes was unable to connect to this iPhone. An unknown error 0xe8000015 occurred.
  2. The error code can be 0xe8000015 or 0xe8000003, less often - 0xe800002d and 0xe8000065.
  3. There is no value.
  4. Failed to send message to device.
  5. An invalid response was received from the device.
  6. iTunes was unable to connect to this iPhone because there was a reading error.

Since the cause of connection errors 0xe8000015, 0xe8000003 and others is the Lockdown directory, you should first fix the problems in it.

Fixing iTunes connection errors:

Main causes of error

There are many reasons for errors; you will have to try and find yours among several possible ones. Often the cause of the error lies in trivial things like a poor connection or Windows security settings. There are also more serious problems that require changes to the internal directories of the iPhone

Main reasons for the error:

  1. Errors caused by connection problems in iPhone or Wi-Fi networks.
  2. Conflicts between iTunes and iPhone with antivirus and security software, as well as the Windows firewall.
  3. Problems caused by incorrect connection of the phone via USB to the computer.
  4. The presence of Jailbreak (hacked iPhone) and downloaded pirated software on it.
  5. iTunes is not installed or updated correctly.

Depending on the error, its code, as well as recent actions The user can find out why the connection between the phone and iTunes is not established.

Network and Wi-Fi errors

The error may appear if Windows is unable to establish a connection with iTunes, iPhone, Apple Stope, mail server or update server. In this case, a note “An unknown error has occurred” or “An error occurred while loading the software” is written in the system window.

Connection, network, Wi-Fi error codes: 17, 1403, 1004, 1013, 1014, 1015, 3200, 3004.

Sometimes the user has nothing to do with it at all - problems occur on the Apple side, and then you just have to wait for the operation of the update servers to normalize. At the same time, most errors can be corrected using the following actions:

  1. Error code 17 . An error with this code appears when a user with unofficial firmware from third-party developers (custom firmware) is trying to change it to another. Similar actions with changing and modifying the firmware can only be performed when the phone is in DFU mode. After entering DFU mode, the problem will disappear.
  2. Error code 1403 . The problem occurs when trying iPhone recovery using damaged firmware. To solve, you should use another download method to download the firmware, or download the firmware from another location. Dream damaged files The update will install normally, without notifications about conflicts with the system.
  3. Codes 3004 And 3200 . It is not the user's fault that these errors appear: they occur when trying to download updates in the first few hours or days after their release. These days there is a huge load on Apple servers, so problems with communication and connection establishment occur frequently.
  4. Codes 1013 , 1014 And 1015 . Appears when trying to update iOS version on iPhone to an older one, or roll back the firmware to previous versions. According to Apple's policy, a return to the old version of the system is possible only within the first 2 weeks after the update. After this, you will not be able to roll back the system using permitted methods.

If all of the above situations cannot be the cause of the problem, you should move on to the next step - fixing problems with the Lockdown directory.

Solving errors 0xe8000015 (0xe8000003) via Lockdown

The Lockdown directory is created after installing iTunes, the first time you connect your iPhone to your computer. The contents of directory files give Windows the right to modify, write, sync, and otherwise interact with files on the device. Third-party firmware, jailbreak and hacked software greatly increase the chance of problems with Lockdown.

The directory may have different locations and other differences depending on the operating system version Windows systems. Therefore, instructions for fixing errors are slightly different for popular versions of this OS.

If the contents of the directory are damaged and error 0xe8000015 appears, you need to reset (delete) the directory:

  1. Close iTunes completely.
  2. Disconnect your iPhone or other iOS device from your computer.
  3. Open dispatcher Windows tasks(key combination Ctrl+Alt+Del).
  4. Go to the "Processes" tab.
  5. Terminate all running processes from the list: AppleMobileDeviceService.exe, APSDaemon.exe, distnoted.exe, iPodService.exe, iTunesHelper.exe, mDNSResponder.exe.

If iTunes is closed, all 6 processes should exit without issue. You need to right-click on each process and select “End Process”. The further sequence of actions depends on which version of Windows OS is used on the computer.

Instructions for Windows 10, 8, 7 and Vista:

  1. Click "Start".
  2. Enter %ProgramData% in the search bar.
  3. Press "Enter".
  4. In the search results, find and open the Apple folder.
  5. Find the Lockdown folder.
  6. Right-click on it and select “Delete” from the context menu.

IN Windows XP this directory is located at a different address and the process for deleting it is different:

  1. Click the “Start” button.
  2. Select "Run".
  3. In the window that appears, enter %AllUsersProfile% and click "OK".
  4. In the search results, find and open the Application Data folder (it may be hidden and read-only, in which case you need to select the “Show hidden files and folders” setting in Explorer).
  5. Find and open the Apple folder.
  6. Find the Lockdown folder and right-click on it.
  7. Select the “Delete” item in the context menu that appears.

If everything is done correctly, the directory will be deleted from the computer. After this you need to do the following:

  1. Relaunch iTunes.
  2. Connect your iPhone (or other iOS device) to your PC.
  3. A window will appear with the text “Do you want to allow this computer to access information on?” — you need to click the “Continue” button.
  4. After this, a window will appear on the iOS device, where you also need to allow access.

If the problem was caused by the LockDown directory, then it is guaranteed to be resolved using the instructions above. Otherwise, you are left to check why else iTunes is unable to connect to this iPhone.

Problems with USB connection

Problems with the USB connection also have unique error codes. From them you can understand which component of the connection failed. On Windows screen An error connecting to the iPhone appears, a message about an unknown error and its code.

USB connection failure codes: 13, 14, 1601-1609, 2001-2011, 4005, 4013

The problem is almost guaranteed to be connection related if the system issues the following warnings:

  • iPhone timed out waiting for a response.
  • The device cannot run faster.
  • An unknown error occurred during synchronization.

In case of errors 13 And 14 The cable may need to be replaced. This often solves the problem if you try iPhone connections A cheap Chinese cable is used to the computer instead of the original one.

There are a few exceptions:

  • Code 13 often appears when trying to install from Windows environment beta versions of iOS.
  • Code 14 may appear when iTunes conflicts with antivirus software.

In this case, you should make sure that software Apple is not blocked antivirus programs and Windows firewall.

Exceptions and non-standard solutions

If reinstalling iTunes and the directory does not help, you should remove all programs that work with iTunes:

  1. Apple Application Support
  2. Apple Mobile Device Support
  3. Apple Software Update
  4. Bonjour
  5. QuickTime

After this, it makes sense to use CCleaner to clean the registry. This can be done manually:

  1. Click “Start”, “Run”.
  2. Enter regedit in the field that appears.
  3. In the registry editor that opens, enter the names of programs and delete the results found.

It is advisable to carry out such actions with sufficient experience Windows operation and more than superficial knowledge of the operating system. Removing unnecessary registry entries can lead to numerous new errors.

You can also go to iPhone or other iOS device and check the remaining free space: sometimes errors occur if there is less than 1 GB of memory left on the device. To do this, go to “Settings”, “General”, “Available”. It may take some time for the system to show the used and remaining space.
