At the same time, many people do not even know that in fact, almost every such problem can be solved quite quickly; it is enough to simply have a list of all possible errors and ways to solve them.

Why does code 0x666D743F appear?

In iTunes, this type of error occurs when there is a certain conflict in the functioning of the files during the startup process. It is most common among Windows OS users. If you want to get rid of this problem, you will need to go to the "Control Panel", then activate the QuickTime settings and turn off Save Mode in the "Audio" section.

Why does error 0xE8000001, 0xE8000050 occur?

In iTunes, error 0xE8000001 or 0xE8000050 appears if the system cannot install the required applications on your gadget. If you have such a problem, you will need to install the latest version of this system. Most often, the error occurs when you try to install any hacked applications. If this is really the case, then you will need to hack your own gadget and then install AppSync on it from Cydia.

0xE8008001 - what to do?

The reason for this is that certain applications use the wrong signature, that is, they are hacked. If you want to install them on your device, you will need to perform the so-called jailbreak of the gadget, and then install the AppSync patch, which is downloaded from Cydia.

0xE8000013 - how to fix it?

iTunes displays an error with this number if a standard synchronization problem occurs, that is, similar codes can periodically appear on any device. To fix this, you will need to re-sync your gadget, and if necessary, you can even reboot it completely.

What to do if code 0xE8000065 appears?

This code may indicate that you have a problem either with the system itself, or directly with iTunes. To fix it, you can simply restart your computer or change the USB port. If this does not help you, then in this case you will need to completely reflash your gadget.

What to do with error 1671?

iTunes error 1671 occurs if the system for checking firmware files is not disabled. If you want to fix it, it is recommended to jailbreak your device. If you need to install custom firmware with iOS 4/5, then when you get iTunes error 1671, you will need to use PWNed DFU. A guide to using the utility is not that difficult to find.

4013 - how to proceed?

iTunes error number 13 or 4013 appears if you are using a faulty cable or the connector into which it is plugged into the system unit is inoperative. To fix the error, you will need to use a new cable, or the best option would be to replace the USB completely. It happens that this will not help, and you will again see iTunes error number 13 or 4013. Then you will need to completely reinstall the system or even use a different computer to install the applications you are interested in.

Error 9 appears. What should I do?

iTunes Error 9 is similar to a computer's Blue Screen of Death if the PC is running Windows. This error means that there is some kind of failure within the kernel. operating system iOS.

It is immediately worth noting the fact that in almost 100% of cases, error 9 iTunes does not appear if the device is using standard firmware. If you are using custom firmware, then it would be best to build a new one.

Eliminating errors 3002 and 3194

Error 3194 in iTunes when restoring the firmware occurs when there are certain problems that prevent the device from accessing the gs.apple.com server. Among the most common reasons For this problem, it is worth noting the changed Hosts file, as well as the complete absence of previously saved SHSH, which are required for the downgrade. Also, one should not exclude the possibility that Apple’s servers on at the moment are simply overloaded, so try the request again via certain time, and it is quite possible that you will not need any additional manipulations to fix the problem.

What to do if error 6 or 10 appears?

If you are trying to install custom firmware on your phone with boot recovery logos that differ from the standard ones, then you may encounter such problems during installation. iTunes often throws an error with this code when you try this action. To get rid of the problem, you will have to install new firmware to your gadget, using another custom firmware that does not have custom boot-recovery logos, or try to use the custom firmware that has already been tested during operation on your device.

Possible 10xx errors and their elimination

This problem can occur if you are trying to flash to an older firmware version than the one you are currently using. Or if you try to update to a modem of a version that does not match your gadget, an update error may appear. iTunes often issues such codes, but eliminating them is not so difficult.

To deal with the problem, you will need to download and use a utility called TinyUmbrella. After the program starts, you will need to click on the Kick Device Out of Recovery button, and then calmly download the programs you need.

Error 54 and its fix

Error 54 occurs if you try to copy an application from another device to your gadget. Most often, this problem occurs when you try to copy any cracked applications or copy licensed applications to a computer that has not been previously authorized.

If this option could not help you, then in this case you will need to go to the settings, go to the "Synchronization" section, then reset the history and completely delete the folder, which is located at C://Documents and Settings/All Users/ Application Data/Apple Computer/iTunes/SC Info. Once this is done, you will need to re-authorize your own computer.

The third option is to open the folder with your media library, and then move the “Music” folder to some other location that is convenient for you. Now you can synchronize your device with iTunes, then return the folder to its place and resynchronize.

The last option is the most difficult, but it is quite effective and allows you to eliminate this error in almost all cases. The use of this method is recommended exclusively for advanced users who know how to work with such equipment.

Initially, you will need to open Cydia, and then download SwapTunes from there. This tweak will allow you to synchronize your device with several media libraries simultaneously. Now we launch the SwapTunes we downloaded, after which we open iFile and go to the following address: var/mobile/media. Here you will need to find a folder called iTunes_Control2, and then remove the number 2 from the name of this folder. The folder itself should be deleted only after you create a new one. After all these procedures, you can safely completely remove SwapTunes, then re-sync the gadget with iTunes and continue downloading the utilities you are interested in.

Error code 9808 and its solution

This problem occurs when you try to log in to iTunes Store. It's worth noting that this is sort of a configuration error in iTunes, so you'll need to fix it by changing certain settings. You will need to go to the control panel, find “Internet Settings” there, then go to the “Advanced” section and check the boxes next to TLS 1.0 and SSL 3.0. In order for the changes you have made to be finally confirmed, you will need to restart your computer.

Mistake #1

Such problems are a consequence of the fact that you are trying to install firmware that does not actually match your version of the gadget. If you notice such an error, you will need to make sure that it is actually suitable for your device. If you are sure that the firmware is up to date, then in this case you will just need to iTunes update.

Mistake #2

Today it is quite rare, since it most often appears when old-generation gadgets are flashed using custom firmware along with activation and subsequent ASR patch. But if you do have it, then the only thing you can do is simply use some other firmware that is current for your device.

Error code 10. What to do?

If you encounter such an error, it is likely that you are using custom firmware that lacks technology Low Level Bootloader, since it is directly responsible for booting your system. To solve this problem, you will need to download or make custom firmware yourself.

What to do with error 11?

The firmware you are installing does not have BBFW. To resolve error code 11, you will need to download the firmware again from a trusted source or use a specialized archiver to add the missing file to the container of the firmware that you are currently trying to install.

What to do if error 14 appears?

This error occurs after you jailbreak unsuccessfully or use a USB connector on your computer that is damaged. To resolve the error, try replacing the USB connector, and if this does not help you, you will have to use complete flashing gadget.

Fixing error 21

The IPSW signature verification mode was not disabled, as a result this error starts to appear when you try to use custom firmware? If you encounter this problem, you will need to install custom firmware using the PWNed DFU utility. It is worth noting that the creation custom firmware in this case it should be done using the PWNage Tool.

Solving the problem with error 23

The reason for this is the occurrence of various problems associated with the hardware component of your device. It is enough to simply determine the cause of this error if your gadget no longer detects the Mac address or IMEI. The only solution in such a situation is to go to service center to qualified specialists, since independent decision does not exist for this problem. It is recommended to go to trusted service centers, since not everyone knows how and can solve this problem.

Cause of error 26 and its solution

The reason for this error is that the NOR is not appropriate for the firmware version you are using. To solve this problem, you can simply download some other firmware file from a previously verified source.

Simple errors 27 and 29

This problem is relevant only for older versions of iTunes (from 8 to 9.1) and at the same time occurs exclusively in the Windows operating system. To eliminate it, it will be enough to simply update the program to latest version, which is relevant today.

Error 28. Why does it appear and how to fix it?

Among all existing reasons In this case, the problem is almost always that the 30-pin connector of your gadget is not working correctly. Again, the only solution is to go to a service center, since we are talking about a hardware malfunction, and carrying out such procedures, even the simplest ones, is highly not recommended on your own.

Code 35. Solving the problem

This error occurs quite often when the device is running on Mac OS X and is a consequence of the fact that the user has incorrect access rights to the folder in which the iTunes library is located. To resolve the error, you will need to launch the Terminal program, log into your account, and then enter the code sudo chmod -R 700 Users Music iTunes iTunes Media.

Code 37. Causes of occurrence and solutions

The reason for this error is most often the use of custom firmware, since it often happens that a custom firmware may use LLB, which is used in another gadget. To prevent this error from appearing again, you will need to create custom firmware yourself, which will use the correct LLB.

Error code 39

The appearance of such an error quite often happens after the system finds some problems with the photo album or with the device’s access to the Internet. To fix it, try creating a completely new photo album, and also update your iTunes installation to the version that is current today. If even this did not help you, then it is likely that the problem lies with the antiviruses or firewalls you are using, so try turning them off as well.

1008, or problems with Apple ID

The reason for error 1008 is that iTunes cannot recognize certain characters that were entered into the Apple ID. Quite often it appears due to the fact that the system was encoded incorrectly. To troubleshoot the problem, you need to open the “Store” tab, then “View my account.” If the data is entered and displayed correctly in the window that appears, you need to click “Exit”. Now you will need to switch the encoding of your system to Win5112 or UTF8, after which you will be able to log into your account again.

1015 and firmware update

Most often, the appearance of this problem is a consequence of the fact that the gadget is flashed to an old version. Do not forget that for downgrading in mandatory SHSH saved in advance should be used, and if you don’t save them, then you don’t even have to think about downgrading.

However, this error is often a consequence of servers being blocked by the Apple system, and to fix it, you will need to completely erase all data about Apple servers from the host file.

47 - unsolved mystery

The most mysterious is iTunes error 47. And experts are working on this problem. Quite often the Windows operating system itself issues this code, and although it seems that this is iTunes error 47, in reality the operating system cannot use this device, since it was prepared for safe shutdown, but was not turned off from the computer. To eliminate this malfunction in this situation, it is quite enough to simply remove the device from the socket and then insert it back.

It is worth noting the fact that even for a developer this is in iTunes unknown error. And to this day, no normal description of it has appeared on the official website. If we are talking specifically about an operating error Windows systems, then you can simply see it, after which the active program window will fly out. In addition, some users have experienced situations where an unknown iTunes error occurred when trying to use a specific device.

Knowing all the above problems, as well as possible reasons their occurrence and solutions, you can freely use iTunes at any time convenient for you. Such errors can occur to every user from time to time, so it is better to prepare in advance for their occurrence and know how to quickly eliminate them.

If the above options for eliminating such problems could not help you, then in this case it is better to contact qualified specialists who have necessary equipment, skills and, of course, experience in eliminating various errors from gadgets.

Sometimes when updating, restoring or iPhone sync and iPad, unknown errors appear in iTunes. In my “iTunes Errors” guide you will find a description of these errors and options for eliminating them.

All errors on iOS are usually associated with iTunes, that is, with the part that is outside the device. Problems in the firmware or system operation are corrected by the developers very quickly, so there are practically no such problems.

Now this is installed on most iPads and iPhones. Means, iOS errors 10 will be the most relevant. They are mainly related to incorrect work some system applications. As a rule, all these problems are quickly fixed with each update, but some users may still encounter them due to the fact that they are using the old version and did not switch to the updated one.

With the advent of the tenth version of the operating system, Apple users were faced with the fact that 10–15% of them fly away in minutes. Although the “ten” should save battery power.

There is only one way out of this situation today - you need to update to the next version. It is no longer possible to roll back to the previous one without a jailbreak, and this is too radical a method. A simple update will affect energy efficiency. In addition, make sure whether it is really due to new version Is your iPad's OS running out faster?

Contacts are missing in the Phone app

iPhone users discovered that some of their contacts iOS installation 10 is missing. Moreover, if you use them in other applications, then they are there, but if you try to use them using standard application“Phone”, then it is impossible to find them.

The way out of this situation is to perform a hard reboot of the device. To do this, hold down the “Home” and “Power” buttons and hold them for several seconds. If after this the error does not disappear, you can try restarting your phone or tablet in the usual way several times.
