The sync button in iTunes doesn't work. Device malfunctions. Conflict with other programs

Apple devices like the 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 music does not sync from iTunes to iPhone. There can be quite a lot of reasons for this. This is especially noticeable when Apple device connects to a computer or laptop with Windows on board. But the problem can be fixed. Below are the simplest methods to help solve errors of this kind.

iPhone won't sync with iTunes: why?

The very first problem that awaits any owner Apple device, is that the corresponding device driver is missing or incorrectly installed in Windows. We are not talking now about initializing the same iPhone as a USB device in the sense of recognizing information on the internal storage.

The problem is mostly that control program iTunes was unable to connect to the iPhone when attempting to connect. And this may be due to the fact that the program itself is “buggy”. The simplest way out would be reinstalling iTunes using the official installer for Windows, downloaded from the developer’s website or from the AppStore.

Music won't sync from iTunes to iPhone: what to do first?

But that's only computer programs. But it also happens that the iPhone does not synchronize with 54) directly on the mobile gadget.

The manufacturer himself recommends rebooting the device, combining the files in the media library (and in small parts), deleting the content and downloading it again, excluding the files from it PDF format. Perhaps the problem of the iPhone not syncing with iTunes will be solved. However, it is worth considering some other points.

Re-authorization

In some cases, the device may seem to establish communication, but in reality this does not happen. To correct such failures, you simply need to log out of your account and then log in again.

As a last resort, the “account” should be deleted, and when the device is rebooted, specify it again. Sometimes it helps.

Solving wireless problems

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

In the very simple case you should set the receipt of addresses to automatic, but sometimes for the task DNS settings you can use Google services, whose addresses consist of four eights or two eights and two fours.

Resetting settings and reinstalling the operating system

Finally, if after this you still receive an error indicating that iTunes was unable to 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 this there is a situation where the iPhone does not sync with iTunes, you will have to use more stringent methods.

In this case, you need to close all programs and Apple computer or PC call Finder app, then for Apple, press the keyboard option Ctrl + Cmd + G (for Windows this does not work), where you need to write /var/db/lockdown (unlocking will take place). In Windows, you can also 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 can be seen 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, resort to complete reinstallation system or download new firmware no need. The methods described above will suffice. You never know, maybe a simple reboot of the device will help. And reinstalling the software in the form of an applet on your phone and computer with Windows won’t hurt either.

On the other hand, if all the above methods do not help and music from iTunes to iPhone does not sync, then you should not be content with what you have. At least the most simple solution can be called deletion iTunes programs from a computer with Windows on board (and it doesn’t matter what version it is) and reinstallation followed by entry into account via your existing AppleID.

But if we talk specifically about Windows, in some cases it may be necessary to remove updates that cause errors this kind. This can be done through the corresponding “Control Panel” menu using the uninstall function latest installations. But the iPhone itself will have to be rebooted (at a minimum).

For the rest, I think special problems not expected. The situation is that either problematic device may be rebooted or will be made re-installation applications on both smartphones and computers. Otherwise, as is already clear, there are no problems. Download the latest iOS version not worth it, especially since the same fourth iPhone versions update is not supported. Do you need it? So, to put it mildly, a smartphone can be “ruined.”

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