Ways to solve iPhone sync problem with iTunes. Google iTunes account sync won't turn on on Android sync failed

Synchronization failure indicates a number of problems. In most cases, a reboot will fix the errors, but if the problems persist, try reinstalling your iTunes or restoring your iPhone, how to do it correctly is described below.

The purpose of synchronization is to restore data in the event of a problem or accidentally deleting an important file. Also helps to get files back to new iphone in case of loss or theft. This action usually takes place in automatic mode, the user only needs to press a couple of buttons. But it happens, there are errors in the program.

ITunes crash

iTunes is Apple's smart file transfer tool. It allows you to correlate changes in documents and files between your devices, making your work very easy. Therefore, when the iphone does not sync with itunes, you have to take on diagnostics. And to identify errors on their own, understanding the intricacies of the software.

Errors can occur when you try to sync your iPhone with iTunes. If you are experiencing this kind of inoperability of Sync, it will be useful for you to find out the possible causes of the problems and their solutions.

Ineffective sync

If all or some of the files cannot be transferred the first time, check that their path is correct on the device and click “Synchronize” (or “Apply”) again. Sometimes iTunes does not notice some files right away, but the second time it will add them to the cloud without any problems.

There are situations when a particular file type cannot go through the procedure and blocks the entire process. If a particular type is problematic - for example, audio or video - remove them completely from your phone and do all the steps from scratch. To do this, open the iPhone settings in iTunes and uncheck the selected sync option, for example, audio recordings, and click Delete. Click "Apply" and wait for the function to complete. After that, double-check the parameter and click "Apply" again.

One-way sync

There are situations when data transmission works in both directions. For example, new apps and updates that you download to your phone are not transferred to your computer, although the postback works fine. This problem is not actually an error, try manually transferring the documents you want. To do this, open the "File" menu (press Ctrl-B if you do not see the menu bar), select "Devices", then "Transfer iPhone from iTunes".

Device malfunctions

If iTunes can't even see the iPhone, you either have a hardware problem - most likely a broken USB cable - or the program itself.

Apple offers a long list of troubleshooting steps for this problem, but the main solution boils down to a few sequential steps:

1. Reboot your computer.
2. Connect your phone to your computer and try to turn on the program again.
3. If the program still does not see your phone, close it and uninstall the application using the Programs and Features panel. Apple recommends removing related components when uninstalling iTunes.
4. Reinstall the application and check it works.

Internet connection check

We try to open any site in a regular browser to make sure that we are connected to the network. The web page opens - everything is in order, but if not, we try to reboot the router or call our provider's hotline. 90% of the problems are solved already at this stage and you can skip the described procedures.

ITunes update

If iTunes on your PC has not been updated for a long time, the problem is most likely an old version of the program. By default, update notifications should appear when a new version is available. Check if you have auto-update enabled, try updating the app manually.

Change USB cable

Sometimes USB ports are the cause of problems, and although this is quite rare, it is very easy to check, so it is worth giving it a try. Now, what you need to do is move the USB cable from one port to another and see if it works. The old wire may need to be replaced. In this case, we do not recommend buying a cheap Chinese analogue - they can often malfunction and even cause smartphone breakdowns.

Reset to factory settings

Factory reset often helps. Open Settings on your phone and tap General, Reset and then Erase All Content and Settings. This option resets the phone to factory defaults, after which it offers the option to restore a device backup.

Attention! These actions will delete the contents of the gadget. Apply only if you have a backup copy of all files, from which you can restore the documents you need.

Failed authorization

Another common cause of problems is when the computer is not authorized in the cloud service. If syncing fails, the “Sync” button is grayed out and unavailable, or nothing is transferred to your iPhone, iPod, or iPad, you may just need to authorize your computer to iTunes:

• Open the program with an iOS device connected via USB.
• Pull down the "Store" menu and click on "Deny this computer".
• Now go back and select "Authorize this computer".
• Enter the Apple device ID and password, then select Authorize.

Everything works, but no music, videos or apps

If Sync now works, but documents, music, or movies are not transferring to iPhone, check the following:

• In the Summary tab, check if Manually Control Music & Videos is turned on or not, try turning it off and back on yourself, then manually drag the song or movie onto your iOS device to force a manual sync.
• Look under the Music, Movies, Applications, TV Shows tabs and make sure Sync Music, Movies, etc. is checked and enabled.
• Try checking and unchecking these boxes, then clicking the Sync button again.

Summarizing

Problems with the transfer of content often occur on Apple devices, which is not a serious problem. Most of them can be solved quite simply and trivially - by authorizing or reloading the application. Or you can prefer manual synchronization of music and media, disable all Sync content functions and synchronize using drag & drop (drag from a folder on your computer to the iTunes window).

There are times when iPhone or iPad also perform or restore a device. If you are facing a similar issue, resetting the Lockdown folder on Mac or Windows can help. Now we will tell you how to do this.

To reset Lockdown on OS X, you must first disconnect all iOS devices from your computer and close iTunes. Then open Finder, hold down the Shift + Cmd + G keyboard shortcut, enter the path below and press Enter.

/ var / db / lockdown

Select all files in this folder and move them to trash. OS X removes files from Lockdown, but not the folder itself.

Everything is a little easier. Again, turn off all iOS devices, close iTunes and click "Start". In the search field, enter the command below and press "Enter".

Double click on the Apple folder where delete the Lockdown folder. Please note that after this you need to restart both the computer and the iOS device, otherwise the system may subsequently generate an error.

If you still have Windows XP, the steps are the same, only the Apple folder will need to be found in Application Data. After that, the device can be reconnected to the computer and be sure to click "Trust".

Apple's devices like iPhone and iPad are considered to be among the most reliable when interacting with software products. However, they are not immune to errors. In particular, sometimes iTunes music won't sync to iPhone. There may be many reasons for this. This is especially noticeable when an Apple device is connected to a computer or laptop with Windows on board. But you can fix the problem. Below are the simplest ways to help solve errors of this kind.

iPhone won't sync with iTunes: why?

The very first problem that lies in wait for any owner of an Apple device is that the corresponding device driver is missing or incorrectly installed in Windows. Now we are not talking about initializing the same iPhone as a USB device in the sense of recognizing information on the internal drive.

Most of the problem is that the iTunes manager was unable to connect to the iPhone while attempting to connect. And this may be due to the fact that the program itself is "buggy". The simplest solution is to reinstall iTunes using the official installer for Windows, downloaded from the developer's website or from the AppStore.

Music not syncing from iTunes to iPhone: what to do first?

But these are only computer programs. But it also happens that the iPhone does not sync with 54) directly on the mobile gadget.

The manufacturer himself recommends reloading the device, merging files in the media library (and in small parts), deleting the content and downloading it again, excluding PDF files from it. Perhaps the issue of iPhone not syncing with iTunes will be resolved. However, there are some other points to consider.

Re-authorization

In some cases, the device may appear to be establishing a connection, but in reality this does not happen. To fix just such failures, you just need to log out of your account, and then re-log in.

In the most extreme case, the "account" should be deleted, and when the device is rebooted, specify it again. Sometimes it helps.

Solve wireless problems

Worse when iPhone won't sync with iTunes over WiFi. Here you will have to check the network settings directly in the Windows system with the installation of the correct parameters of the TCP / IP protocol of the fourth version (v4), which is currently used most actively (the version of IPv6 has not yet reached us).

In the simplest case, you should set the receipt of addresses on an automatic machine, but sometimes you can use Google services to set DNS parameters, the addresses of which consist of four eights or two eights and two fours.

Resetting and reinstalling the operating system

Finally, if after that you still get an error indicating that iTunes could not connect to the iPhone, you can try to do a master reset. To do this, you need to use the menu for deleting personal data and settings from the main section.

If, after that, there is a situation where the iPhone does not sync with iTunes, you will have to apply more stringent methods.

In this case, you need to close all programs and call the Finder application on the Apple or PC computer, then hold down the Ctrl + Cmd + G keyboard option for Apple (this does not work for Windows), where you need to write / var / db / lockdown (unlocking will take place) ... In Windows, you can still try to go to the AppData directory, which is hidden, and delete the Apple directory from there, but I think this is not the best option.

Conclusion

As you can see from all the above material, the question of why the iPhone does not sync with iTunes can be considered settled. In fact, in most cases, you do not need to resort to a complete reinstallation of the system or download a new firmware. The methods described above will be enough. You never know, maybe a regular reboot of the device will help. And reinstalling the software in the form of an applet on your Windows phone and computer won't hurt either.

On the other hand, if all the above methods do not help and the music does not sync from iTunes to the iPhone, you should not be content with what you have either. At the very least, the simplest solution is to uninstall iTunes from your Windows computer on board (and it doesn't matter at all which version) and reinstall it, and then log into your account using your existing AppleID.

But if we talk specifically about Windows, in some cases it may be necessary to remove updates that cause errors of this kind. This can be done through the corresponding menu "Control Panel" using the function of uninstalling the last settings. But on the iPhone itself, you will have to reboot (this is at least).

For the rest, I think, no special problems are foreseen. The situation is such that either the problem device itself can be rebooted, or the application will be re-installed both on the smartphone and on the computer. As for the rest, as is already clear, there are no problems. It is not worth downloading the latest version of iOS, especially since the same fourth versions of the iPhone do not support the update. Do you need it? So, to put it mildly, and a smartphone can be "ditched".

But in principle, the system can be repaired, and very simple. To do this, you just need to follow the recommendations outlined above. And the problem itself, how exactly to establish the connection between a mobile device and a computer, remains with the user. In any case, an option can be found. But it is the reboot that will be required initially. The emphasis is on this. In addition, reinstalling the program itself or its updates can solve some problems associated with the lack of synchronization.

When working with Apple devices, you often have to use the sync function. It is designed to update and add data between devices so that everyone as one has a common information. Although Apple gadgets are famous for their reliability, even with them failures happen. Therefore, it is not always possible to synchronize the iPad.

Why are we syncing data? So that they are available on every device and replenished when new data appears. There are many reasons that do not allow synchronization. Synchronization can be configured between gadgets, computer, aytyuns program. Sometimes it is not possible to do it with the setting, there are several reasons.

Gadget malfunction

This can happen with any tablet. You can fix this problem by restarting the device. You need to do this for a tablet and a PC. The computer can be rebooted through the standard reboot function. To restart the tablet, hold down the power key until the shutdown message appears and then swipe it to the side. After a couple of minutes of waiting, you can turn on the gadget by holding down the "power" button until the apple-shaped logo appears.

Old version of the program

Another common cause is an outdated version of iTunes. You cannot install the program once and use it all the time. It requires constant updating. If it is not updated, there will be failures. To fix this problem, check the program for updates and install them, if any. After that, be sure to restart your computer and re-sync. Perhaps the sync is now successful.

ITunes crashing

System crashes could occur while the PC was running. They could damage the program files. This can lead to malfunctions in its functioning. How to remove this problem? To do this, completely remove the program from the PC. Standard deletion can leave a lot of files in the registry, which will not fix crashes.

To completely remove the program, download Revo Uninstaller. Next in the list of this application, remove sequentially: iTunes Apple Software Update , Apple Mobile Device Support and the last Bonjour ... Check the files for Apple products, if you find them, delete them. To clear it, click on the name of the program with the right key of the manipulator and click "delete". Then just follow the instructions. Reinstall iTunes after uninstalling.

Authorization failures

This problem is displayed as a gray sync button. To eliminate this error in operation, try to re-authorize the PC. In iTunes, find the "account" item. In the expanded list, click the authorization option. In another pop-up menu, select "deauthorize this PC". At the end of the process, you need to re-authorize the PC.

Follow the same steps, only in the last menu select "authorize this PC". The system will send you a registration form, where you need to enter your details and the secret code from Apple ID. If the information matches, the computer will be authorized. Now you can repeat the tablet setup with iTunes.

USB cable

Probably the first thing to check is the serviceability of the cord. Examine it carefully for damage or kinks along its entire length. The use of non-original components can also cause a lack of response. How to sync the device in such a situation? Replace the cord with a known good one and rerun the procedure.

USB connector

Another reason why you might not come with customization. Damaged connector. The frequency of use of such connectors leads to the fact that they often break. You can get out of this position by switching the plug to a different port. Do not use additional adapters, this will slow down the data transfer rate.

Tablet crash

Reset settings on iPad. This can be done through the basic settings of the device. In the area that opens, find the "reset" column and go to it. From the list provided, click on the "reset all settings" column and wait for the process to complete. Try to sync the tablet, if it does not work, then in the same list, click on "reset content and settings." Wait for the end of the reset. This will reset the settings to factory defaults. If, after the above measures, you still cannot configure your gadget with iTunes, contact technical support for advice.

How to sync iPad with iTunes

When you connect your tablet to your PC for the first time, a dialog box will be available. Here you can specify according to the list the data that will be synchronized each time you connect to the program. Those columns that you do not specify will not be customizable. Here you can also combine data on your PC and tablet into one. The speed of the process directly depends on the amount of data being processed.

You can make this setting after uninstalling the program and reinstalling it. Now you know how to sync your tablet with iTunes and you know the reasons why this process may fail.
