The whole procedure is described in

The union of the iTunes program and iOS devices, in general, can be considered stable, but sometimes updates, restores, content synchronization and other operations involving the interaction of the "apple" and the specified utility can be interrupted by an error with one number or another. This article will show you what to do if iTunes gives error 1.

The support section on the official Apple website contains information according to which error 1 indicates a particular hardware malfunction. And we are not necessarily talking about a malfunction of the iPhone or other "apple" device, when interacting with which the program generated an error. It is likely that the computer or the modem or the cable or USB port is to blame ... And here it is important to correctly diagnose.

However, it is also indicated in the support section that if an error occurs with any number, you first need to take a number of standard measures to eliminate it - these standard measures do not depend on the error number. Well, if the universal instructions do not help, it is worth moving on to special guides, which are different for most errors.

This is the way we will go - first we will execute standard instructions, and then special ones - in the case of error number 1, special measures are understood as hardware diagnostics.

Classic error elimination scheme

It is worth noting that if error 1 appeared immediately when the iPhone was connected to the computer and when iTunes was launched, then, most likely, the matter is precisely in hardware malfunctions and standard error elimination measures are unlikely to help.

In the same case, when the error did not appear immediately, but made itself felt during the update or synchronization - that is, the process was launched, but could not be completed - then there is a very high chance that the situation will be corrected by standard measures.

However, our advice is that whenever an error occurs, you still need to follow the standard instructions.

The first rescue measure is a reboot. Yes, the advice is ballroom, but banality does not negate the effectiveness. A reboot is required both for the program itself and for the iOS device. To restart iTunes, just close and open the program again. To reset the gadget, disconnect it from the PC, hold down the Home keys (on the iPhone 7 - the volume down button) and Power simultaneously and hold until the "apple" appears on the screen.

ITunes update

If the reset does not save, we proceed to more serious measures. The first such measure is to update iTunes to the most recent version. To do this, in the program menu, click "Help", then "Check for Updates", if you find actual updates, follow the instructions to download and install them.

Updating other programs

At first glance, this seems strange, but third-party programs can interfere with the interaction between iTunes and the iOS device if they are not updated. An outdated version of any program can crash and slow down your computer, as well as interfere with the performance of other utilities.

Therefore, if the iTunes update did not fix the situation, try installing all the latest updates for your PC. If you have a Mac, go to the App Store and download updates from the section of the same name. If you have a Windows PC go to "Start", then "Windows Update", activate the detection of updates, and then download the found ones.

Disabling security programs

Another example of software conflict is overzealous security software. iTunes, when performing certain operations, contacts Apple's servers, that is, in fact, it goes online without the user's knowledge - antivirus and / or firewall can consider such activity suspicious and blacklist iTunes, and error 1 or another will appear. To avoid such problems, it is better to disable security programs during the interaction between iTunes and the iOS device. Afraid of even leaving your computer unprotected for a while? Then go to the settings of security programs and add iTunes to the list of trusted programs, which, as they say, can do anything.

Checking the maximum version of the operating system

If all of the above measures did not lead to positive results, make sure that you are not trying to use iTunes to install the firmware on an iOS device for which it is already out of date. For example, if you want to install iOS 10 on iPhone 4S, the update will certainly be interrupted by an error, because the maximum supported 4S version is iOS 9.3.5. How to find out the maximum version of iOS that is allowed to be installed on your apple model? It's simple - ask Google.

Reinstall iTunes

And finally, another important measure is reinstalling iTunes. Sometimes a regular update is not enough to fix program errors, in which case you need to try reinstalling. To do this, uninstall the utility from your PC completely using the Add / Remove Programs tool (Start / Control Panel / Programs and Features), or through a special uninstaller program, for example, Revo UnInstaller. Before uninstalling, make sure iTunes is not running - the program must be closed.

When the uninstallation is complete, restart your computer, download the latest version of iTunes from here and install it on your PC, following the instructions of the installer.

Diagnosing hardware failures

So, if all the standard measures did not help, then most likely the matter is in a hardware problem. However, please contact Apple Support before proceeding with the diagnosis. If its specialists turn out to be powerless, you will have to independently determine what is broken.

As we mentioned above, the culprit may be the computer itself, the connecting cable, USB port, modem, and of course the iOS device itself.

The easiest way is to exclude the "suspect" in the person of the USB port - connect another device through it. If it works fine without error, then it’s not the connector.

Then we exclude the cable. In order to understand that this element has nothing to do with it, you need to connect the device through another cable. Ask your friends - iOS devices are very popular, someone will probably find it. Just keep in mind - the cable must be either original or certified, otherwise the diagnostics cannot be called competent.

Does the error appear with another cable? Then the next suspect is a modem. iTunes uses the network when interacting with an iOS device, so it is imperative to check it. To check the modem, as you probably already guessed, you will need to connect your computer either to the network via another modem or generally via Wi-Fi.

The network is different, but the error is there? It remains to diagnose the computer itself. Here everything is according to the standard scheme, in order to probably eliminate the problem with your PC, connect the iOS device to some other computer.

Does the error still exist when connecting the device to another PC? Well, in this situation, we can say with a probability of 99% - the matter is in the hardware problems of the "apple" itself. In this case, you have one way - to a service where your iOS device is diagnosed and a verdict is issued.

Let's summarize

Error 1 can be either software or hardware. But, one way or another, you first need to try to eliminate software conflicts, and only then resort to hardware diagnostics. It should be noted that it is not always the iOS device that is to blame for the problem. During the diagnosis, you can identify the culprit of the problem and contact a specialized service center.

Consider the options for our actions for this error. First, let's define what causes -1 (1) error when updating iPhone. Immediately sad news - as a rule, this problem is directly related to the faulty unit in the device, and specifically to the modem. We will consider options for the rehabilitation of the device without the need to contact the service, so to speak at home. So let's start point by point.

First, we need to rule out possible reasons that prevent the iPhone from being flashed through iTunes. For some iPhone owners -1 (1) the error appears due to:

1. Usage "Gray" non-certified wire (you need to use the original cable)

2. Installed outdated version of iTunes on your computer (you need to download new iTunes version)

3. Other iPhone users may be helped by running iTunes from administrator name or in compatibility mode.

The problem is that these methods help only a small percentage of people, everyone else must accept the fact that the device has hardware problems.

The most important and common reason is this is a breakdown of the modem... You can tell by the following signs:

1.Shortly before the appearance errors -1 (1) the phone worked unstably, from time to time it lost the network, and then found it, and this happened even with a confident signal reception.

2.In the process of restoring the device, the error appears only at the last stage, when the process is already coming to an end.

3. The battery was updated or some other type of intervention was made in the device.

4.Water drop, phone drop

5.The appearance of a window with error -1 (1) in the iTunes program

If you admit any of these options, then be 99% sure that error -1 in your case is connected with damage to the modem.


We have determined that the modem is at fault. Consider options for further action:

1. The correct way to solve errors -1 (1).

This is the smartest option. You need to visit our service center. If your phone is under warranty, don't hesitate, take it to an Apple Authorized Service Center. Given the feature errors -1 (1) appear under mechanical stress, you should be prepared for the fact that you may be denied a free official repair, however, we strongly advise you to try.

If the warranty is over, then we begin to carefully choose the service. The service center specialists must have the necessary skills and special tools to properly solder your modem. We strongly advise against going to a tent on the market, in the best case, you will get the phone back with the same error, in the worst case you will have to repair something else.

Therefore, if you decide to contact the service, choose proven places with recommendations and a quality guarantee.

Consider a treatment option -1 (1) errors without soldering the modem... This can be done in any workshop, but you yourself can try to do it yourself, saving yourself money.

2. Incorrect, but working method in some cases.

It is wrong because we strongly discourage doing this with your device. But since there is an option, we will consider it.

Be careful! You take responsibility for all the consequences!If there is a guarantee, after these manipulations, you can forget about it. There is a chance to harm the phone even more and damage something else inside the device. And there is no guarantee that this will help your iPhone. If you do decide, proceed with extreme caution.

Perhaps the following methods will only help to flash the phone with an error through iTunes and revive it. Then you can use it, for example, as an iPod, but it will not help to restore the modem and it is better not to rely on the iPhone to be able to use the cellular network stably after that.

Then consider the actions:

1. Freeze iPhone. Freezer, refrigerator, maybe winter will help you with this. Don't forget to pack your gadget in a plastic bag. Leave it for 15-20 minutes in the selected cold place and then try to flash the iPhone through the program iTunes... Someone is flashing the phone without pulling it out of a cold place. Whatever you think of us now, but it helps someone to flash the device to the end.

2. Heat up the iPhone. It is best to heat the modem directly and use special equipment for this, this will help to avoid overheating. Then try to flash the iPhone while it is still hot. True, there is information on the forums that it was possible to complete the restoration or update of the iPhone to the end, immediately after the phone warmed up from charging. Such simple heating allows you to "slip through" error -1 (1) and bring the phone back to life.

Cold or hot.

The methods are certainly unusual, and even risky. But when you have nothing to lose, you have to try even the most incredible. Only very carefully.

Even if you managed to complete the restoration or update of the iPhone, then most likely you will have an iPod in your hands - it will not be able to catch the network, and if it can, it is unstable. But you might be lucky ...

Still, a -1 (1) error is serious enough.

Today we told you about all the solutions errors -1 (1). It's up to you which method to choose, but if you want not just to revive the phone, but to make it work fully, then our service center is at your service. We will solve this problem as soon as possible.

Often, during the update, various kinds of errors can appear. These can be both hardware-related problems and common errors that are caused by some kind of conflict in the software. Speaking about the unknown error -1 at 5s, it should be noted that in most cases, this problem is associated with a malfunction of the modem in the mobile gadget and you cannot do without a trip to the service center. However, there are isolated cases when it is possible to reanimate a mobile phone at home.

Causes of the unknown error -1 iTunes

  • Using an uncertified cable, a person puts himself at risk, because the number of system errors can be increased significantly due to this problem. Purchase an original cable for your iPhone;
  • iTunes is not the latest version on your computer. To solve this problem, you just need to update the utility by downloading it from the official Apple website;
  • iTunes was not launched with administrator rights.


Modem breakdown is a common cause of breakdown

The most common reason for which iTunes can give error -1 is precisely the breakdown of the modem. There is a list of signs by which you can determine that it is because of this reason that error 1 occurred.

Before the error 1 appeared when restoring the iphone 5s, the device often lost connection, even in those places where the signal level was strong before, error -1 appears only at the end of the update process, the smartphone fell or got wet - these are all signs, which indicate that the modem in the iPhone 4S, 5S has been broken.

Solution for error -1 iTunes

The only correct solution would be to go to the service center, and all due to the fact that it is necessary to rewire the modem and its components. The workshop must be chosen carefully, because most repair shops on the market deal exclusively with replacing the battery or screen. In the best case, after waiting, you will receive an iPhone with the same error, and in the worst case, the craftsmen can still break something if you do not approach the choice of the workshop wisely.

If the iPhone was under warranty, then no one will repair it for free, because the modem blade is mechanical damage caused by the device falling from the maximum permissible height. Even if there is no external damage, there is no guarantee that nothing has happened to the device itself.

Tips for fixing the error without going to the workshop

Cool down your smartphone, and then try to flash it. This is too peculiar a way, but sometimes it works flawlessly. Among other things, some masters, on the contrary, advise to heat the device with a special device (it is the modem that needs to be heated) and then try to get rid of error -1 by repeating the process of updating (restoring) the device again.

Conclusion

As it became known, "modem dump" is an extremely serious problem that occurs with 5S. Although there are methods by which you can get around this problem, they are not very relevant. Today there are many different recommendations, however, as mentioned earlier, a trip to a service center that repairs Apple devices (iPhone, iPad) is the right decision. By spending a small amount, a person can solve the -1 error that may occur on the device. Solving this problem at home can only harm your device, therefore it is not recommended to use them - a person does this at his own peril and risk.

They do not complain about the quality of products from a well-known giant company, while performing all sorts of procedures in iTunes, users encounter errors that sometimes do not bode well for devices. Many of the failures arise for software reasons and can be eliminated quite simply, while others indicate hardware malfunctions and require a more serious approach to treatment (often not without money). The code assigned to each error helps to get closer to the solution, revealing the possible causes of the problem, but still cannot determine the "root of evil" with one hundred percent probability.

Fixing error 1 in iTunes.

Unknown errors 1 and -1 in iTunes, however, like many failures with other codes, appear when working with the program due to provoking factors of a different nature. Most often, a notification indicating this problem occurs during the process of updating or restoring the firmware of an iPhone 4, 4s, 5, 5s or other Apple devices. At best, error 1 in Aityuns has a software solution and is caused by a software conflict, damaged firmware files, improperly created assembly, etc., and at worst, by hardware problems, such as faulty modem microcircuit, flash memory and other unpleasant moments. The chances that a failure with code 1 (-1) is provoked by the failure of the device's elements are much higher if the iPhone has previously been dropped, hit or other mechanical damage, water got into it, etc.

Let's consider software methods for fixing the problem, since in some cases they are very effective, and before taking the iPhone to the service, it is advisable to try to cope with the task yourself using simple solutions. The key to successful synchronization of iPhone with iTunes is a stable Internet connection, so you should make sure that all network settings are correct and that you use the computer as an administrator. It is also important to make sure that the physical connection between the devices is complete and the USB cable does not come off. Although the percentage of the probability of a system failure is negligible, you can still be among those lucky ones who managed to get rid of 1 error by simply rebooting the devices. The computer restarts in standard mode, and the iOS device restarts in forced mode.

Method 1. Replacing the cable, using a different USB port

It is possible that error 1 was provoked as a result of cable damage or the use of an unoriginal one. If any defects, however minor, are found during inspection, the USB cable should be replaced. The same applies to cables of Chinese origin. It is also recommended to try connecting the device to a different port. You need to connect directly, without using those that are built into the keyboard, hubs, etc. It is better if it is a connector on the motherboard side (for a PC). In addition, you can try to flash on a different computer.

Method 2. Disable antivirus

Many people helped to fix the error number 1 by disabling the security software. If the failure occurred as a result of a conflict between defenders and iTunes, which is often the case, then it is necessary to disable the antivirus, firewall or firewall while performing the update procedure, restoring the firmware. If error 1 is not repeated, we add Aytyuns to the list of exclusions in the antivirus program settings.

Method 3. Using a different firmware

Failure with code 1 when working with iPhone 4, 4s, 5, 5s and other "apples" often occurs due to incorrect assembly of custom firmware, the presence of damaged files, or a conflict between iOS and iTunes versions. The loaded OS may also simply not be suitable for your device. If one of the listed options is guilty of error 1 (-1), then you can re-download the firmware, rebuild it, or use another suitable version.

Method 4. Update and reinstall iTunes

For the program to work correctly, it must be updated to the latest available version. Perhaps the appearance of error 1 in iTunes is provoked by an imbalance of the program and firmware. It is recommended to check for updates and, if necessary, to refresh iTunes. If the method did not work, reinstalling the application, which implies the complete removal of iTunes and all its accompanying components, can save the situation. After uninstalling the computer, you must restart and install the latest version of the program.

Method 5. Launch iTunes in Compatibility Mode

Often the problem is eliminated by running the program in compatibility mode with the selected operating system. To do this, we perform the following actions:

  • by right-clicking on the iTunes shortcut, we call the menu;
  • at the bottom of the list, click "Properties";
  • in the window that opens, in the "Compatibility" tab, check the box next to "Run the program in compatibility mode" and select the OS version below;
  • save the changes.

In the same way, by calling the menu, you can run the program as administrator.

Method 6: Installing available Windows updates

If the system has not been updated for a long time, errors are also likely due to software conflicts, so you need to search for available updates for the current OS version and install them. You can use the option from Windows Update.

Method 7. Restoring to factory firmware using Recovery Mode

In case of error 1 in iTunes, Recovery Mode can help, which, like DFU Mode, is provided for Apple devices in severe cases when the device does not respond to standard actions. Before returning to the default settings, it is advisable to get a backup copy, since user data will be lost. You can enter this mode as follows:

  • turn off the device;
  • press and hold the "Home" button;
  • without releasing the buttons, we connect the iPhone to the computer using the original cable;
  • evidence that the smartphone has entered Recovery Mode will be the image of the iTunes icon and the USB cable;
  • run the program, where you can see that the emergency recovery mode is running.

If it was not possible to reanimate the iPhone at home, a trip to a service center is inevitable. The most common cause of a 1 (-1) error is a modem blade, but sometimes other elements of the device are to blame. It may be necessary to solder or replace parts, which is best done in a service by the hands of professionals.

A malfunction of the modem is also indicated by irregularities in the operation of Wi-Fi and Bluetooth, but in order to completely determine the cause of error 1, diagnostics are necessary. You can also try to flash the smartphone by removing the battery or just the board, in some cases this eliminates the problem.
