Often, when updating, various kinds of errors can appear. These can be both problems related to the hardware side, as well as ordinary 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 connected precisely with a modem malfunction in mobile gadget and without going to service center can't get by. However, there are isolated cases when it is possible to reanimate mobile phone at home.
Causes of Unknown Error -1 iTunes
- Using an uncertified cable, a person puts himself at risk, because the amount system errors can be increased many times because of this problem. You should purchase an original cable for your iPhone;
- iTunes on the computer is not the latest version. To solve this problem, it is enough just to update the utility by downloading it from the official Apple website;
- iTunes was not launched with administrator rights.
Modem failure is a common cause of failure.
The most common reason why iTunes may give a -1 error is a modem failure. There is a list of signs by which you can determine that it was because of this reason that error 1 occurred.
Before error 1 appeared when iphone recovery 5s, the device often lost connection, even in those places where the signal level was confident before, the -1 error appears only at the end of the update process, the smartphone fell or moisture got into it - these are all signs that indicate that the modem was broken in iPhone device 4S, 5S.
Error Solution -1 iTunes
The only right decision would be to go to a service center, and all because it is necessary to re-solder the modem and its components. The workshop must be chosen carefully, because most repair shops on the market are associated exclusively with the replacement 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 may break something else if you do not choose 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 visiting the workshop
Cool the smartphone, and then try to flash it. This is too peculiar way, but sometimes it works flawlessly. Among other things, some masters, on the contrary, advise heating the device with a special device (it is the modem that needs to be heated) and then trying to get rid of the -1 error 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, going to a service center that repairs specifically apple devices (iPhone, iPad) is the right decision. By spending a small amount, a person will be able to solve the -1 error that may occur on the device. Solving this problem at home can only harm your device, so it is not recommended to use them - a person does this at his own peril and risk.
Have a good day today, let's talk about error 1 (-1) iPhone. This error can occur either due to a software failure or due to a hardware failure. In this article, we will analyze the causes leading to iPhone error 1 and advise different ways to resolve this error.
Software solution iPhone errors 1
1. Refresh iTunes up to date
2. Run iTunes in compatibility mode and fromadministrator name.
3. Disable antivirus;
4. Use the original cable
5. When Recovery help Mode try to restore the firmware via iTunes to the factory.
6. When restoring, try different usb ports You can also try restoring from another computer.

4. Modem processor (U1_RF)
5. Transiveroa (U3_RF)
8. Battery
7. Power controller (U7)
9. Bottom train
10. Inductor at the output of the modem power controller
The most common cause of iPhone error 1 is a modem failure. Here are the symptoms by which you can understand that your modem is faulty:
- When trying to restore iPhone process firmwarereaches about 60% and then gives an error 1 just inthe beginning of the modem firmware or at 99%.
- IMEI does not show through * # 06 #
The network disappears and a constant search for the network begins
Wi-Fi periodically becomes inactive (switch inactive)
- The battery has been replaced or some parts have been replaced.
- iPhone dropping or getting wet
Ways to solve error 1 iPhone
1. The first and obvious solution is to take the smartphone under warranty (if it has not expired)
2. Put the phone in the freezer for 20 to 40 minutes. Then get it and immediately flash it (some people plug the cable from the laptop into it right there and sew it). The principle of operation is very simple - the geometry of the contacts changes with temperature, the "broken" connections converge again. Here, of course, the question arises - why did everything work fine before the firmware? As far as I know - the fact is that a number of contact "legs" of the modem are used only for firmware purposes and are not required during normal operation. If these "legs" have defects / dumps, then we get error 1 iphone.
3. It also helps many to warm up the phone if I have a soldering iron, you can warm up the modem itself or the modem power controller (pre-remove the metal screen) which is located in the area of the sim tray.If there is no hair dryer, then you can warm up the back cover of the iPhone with a regular hair dryer for about 1 minute. During the firmware process, you can try to put pressure on the modem, it can help.

When working with iTunes absolutely any user can suddenly encounter an error in the program. Fortunately, each error has its own code, which indicates the cause of the problem. This article will focus on a common unknown error with code 1.
Faced with unknown error with code 1, this should tell the user that there are problems with software. There are several ways to solve this problem, which will be discussed below.
Method 1: Update iTunes
First of all, you need to make sure that you have the latest software installed on your computer. iTunes version. If updates for this program are found, they will need to be installed. In one of our previous articles, we already had a chance to tell you how to search for updates for iTunes.
Method 2: Checking the Network Status
As a rule, error 1 occurs during the process of updating or restoring an Apple device. During this process, the computer must ensure a stable and uninterrupted Internet connection, because before the system installs the firmware, it must be downloaded.
You can check the speed of your Internet connection.
Method 3: cable replacement
If you use a non-original or damaged USB cable to connect your device to your computer, be sure to replace it with a whole and always original one.
Method 4: Use a different USB port
Try connecting your device to a different USB port. The fact is that the device can sometimes conflict with ports on the computer, for example, if the port is located in front of system block, built into the keyboard or using a USB hub.
If you are trying to install firmware on your device that you previously downloaded from the Internet, you will need to double-check the download, as you may have accidentally downloaded the wrong firmware for your device.
You can also try downloading the desired firmware version from another resource.
Method 6: Disabling Antivirus Programs
In rare cases, error 1 can be caused by security programs installed on your computer.
Try to suspend all antivirus programs, restart iTunes and check for error 1. If the error is gone, then you will need to add iTunes to the exceptions in the antivirus settings.
Method 7: Reinstalling iTunes
In the final method, we suggest that you reinstall iTunes.
iTunes must first be removed from the computer, but this should be done completely: remove not only the media combine itself, but also other Apple programs installed on the computer. We talked about this in more detail in one of our previous articles.
After downloading RePack with a game or program from the Internet, many users complain about an error that occurs during installation. As a rule, it says: "Unarc.dll returned an error code - 1" or any other number instead of one. In this article, we will go through six ways to fix this problem, so read it to the end to exactly solve the problem.
Determining the nature of the error
To begin with, we will try to figure out why "Unarc.dll returned an error code - 1" at all, and only then we will move on to solutions.
It should be said right away that this error is related to unpacking data and can be divided into two categories:
- An error that cannot be corrected.
- An error that can be corrected.
Now let's take a closer look at these two points.
A mistake that cannot be fixed
Situation: " Unarc.dll returned an error code - 1 "can be critical, that is, there is no way to fix the error. As it was said, this is related to the archive, and the error occurs during its unpacking. In this case, the message will also indicate the following: "ERROR : file [path to archive] failed CRC check".
Error that can be fixed
Along with an error that cannot be corrected, there is another one that can be eliminated. It should be noted right away that if after the line "Unarc.dll returned an error code - 1" there is a mark in brackets: (decompression fails), then given error fix it in one of the ways that we will offer you in this article. It is also worth saying that the error is directly related to unpacking the archive, or rather, to the archiver itself, but there are also cases when the reason is slightly different. All this will be discussed below.
Method one: installing the archiver
As mentioned above, "Unarc.dll returned an error code - 11" or some other number is associated more often with the archiver. The fact is that the creators of RePack "s often use rare archivers in order to reduce the final size of a game or program as much as possible, and users do not always have tools on their computer to work with such archives.
Luckily, the fix for this error is quite simple, all you need to do is download and install the 7-Zip program.
Method number 2: change the installation address
If you already have 7-Zip installed, or its installation did not help, then you can use the second method and fix the problem with "Unarc.dll returned error code - 11". There are frequent cases when this message appears due to the presence of Russian characters on the installation path. As you might guess, all you need to do is rename the folders using Latin characters.
Method three: increase swap space
A message such as "Unarc.dll returned an error code - 14" may also occur due to the small size of the paging file. Good for operating rooms Windows systems this volume can be adjusted at any time:
- To do this, you need to open the "Run" utility by pressing the keys Win+R, and execute the command in it sysdm.cpl.
- Then in the window that appears, move to the "Advanced" section, there click on "Parameters" in the "Performance" area.
- In the new window, go to "Advanced" again and click "Edit ...".
- Next, the "Virtual memory" window will appear, where you need to uncheck the first item, specify any disk other than the system one, and indicate the maximum size that corresponds to the size of virtual memory.
- Then click "Set" and "OK".
Method number 4: replacing RAM
Continuing the conversation, how to fix "Unarc.dll returned an error code - 1", we note that this may be due to insufficient volume random access memory. Unfortunately, in this case, only its increase will help. However, there is a good side - this problem appears very rarely.
Method five: disable antivirus
Sometimes, especially when you install RePack and not a license, an error can appear due to an antivirus. The fact is that it can consider the game files to be infected and move the necessary libraries that are used for unpacking and installation to quarantine.
What to do with "Unarc.dll returned error code - 12" if it was caused by an antivirus? In this case, you just need to go to the antivirus settings and disable it during the installation. After that it can be turned on again.
Method number 6: disk analysis
There is another reason that completely excludes the possibility of installing the game. It is directly related to your hard drive. The problem is that it can be damaged. At the same time, interaction with it is partially limited: you can move, copy, and drop files from a USB flash drive, but it’s not always possible to install the game.
In this case, a replacement is necessary, but before going to the store, it is better to scan it first. To do this, open the "Run" window and type the following command cmd- will open " Command line". In it, you need to perform the following task: chkdsk C: /F /R /B. As a result of the scan, you will be able to understand whether your disk is normal or not. And if the results are disappointing, then you should think about purchasing a new drive, since with a high probability it will completely stop functioning soon.
Method seven: installing a dynamic library
Sometimes the error can be caused by the lack of appropriate libraries. In this case, it will be enough just to download them from the Internet and place them in the desired directory.
The following dynamic library files are needed: ISDone.dll And Unarc.dll. Download the dynamic library file ISDone from a site you can trust, also download and Unarc. Once downloaded, place them along the path - C:\Windows\System32(32-bit system) or C:\Windows\SysWOW64(64-bit system). After that, the error should disappear.
They do not complain about the quality of products from a well-known giant company, while performing all kinds of procedures in iTunes, users encounter errors that sometimes do not promise anything good devices. Many of the failures occur for software reasons and can be fixed quite simply, while others indicate hardware malfunctions and require a more serious approach to treatment (often not without financial investments). The code assigned to each error helps to get closer to the solution by revealing possible reasons malfunctions, but still not able to determine the “root of evil” with absolute certainty.
Fix Error 1 in iTunes.
Unknown error 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 the iPhone 4, 4s, 5, 5s or other Apple devices. At best error 1 in iTunes has software solution and is caused by a software conflict, corrupted firmware files, incorrectly created assembly, etc., and at worst, hardware problems, such as malfunctions of the modem chip, flash memory, and other unpleasant moments. The chances that a failure with code 1 (-1) is caused by the failure of the device’s elements are much higher if the iPhone has previously been subjected to drops, shocks or other mechanical damage, water has entered it, etc.
Consider software methods 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 you are using the computer as an administrator. It is also important to make sure that physical connection between the devices is done and the USB cable does not go away. 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 devices. The computer restarts in standard mode, and the iOS device 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 damage to the cable or the use of a non-original one. If during inspection any defects, even minor ones, are found, the USB cable should be replaced. The same applies to the cable 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 from the side motherboard(for PC). In addition, you can try to flash on another computer.
Method 2. Disabling the antivirus
Many people were helped to fix error number 1 by disabling security software. If the failure occurred as a result of a conflict between the defenders and iTunes, which happens often, then you need to disable the antivirus, firewall or firewall for the duration of the update procedure, restore the firmware. If error 1 does not reoccur, we add iTunes to the list of exceptions in the settings of antivirus programs.
Method 3. Using a different firmware
Crash 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 iOS versions and iTunes. The downloaded OS may also simply not be suitable for your device. If one of the options listed is responsible for 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 in the program and firmware. It is recommended to check for updates and, if necessary, “refresh” iTunes. If the method did not work, reinstalling the application, which implies a complete uninstalling itunes and all its accompanying components. After uninstallation, the computer must be restarted and installed latest version programs.
Method 5: Run iTunes in Compatibility Mode
Often the problem is fixed by running the program in compatibility mode with the selected operating system. To do this, perform the following steps:
- click right button click on the iTunes shortcut to 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 this 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 an administrator.
Method 6: Install available Windows updates
If the system has not been updated for a long time, errors due to software conflicts are also likely, so you need to search for available updates for the current OS version and install them. You can use the option from the "Windows Update".
Method 7. Restore to factory firmware using Recovery Mode
In case of error 1 in iTunes, the mode can help recovery mode, which, like DFU Mode, is provided for Apple devices in severe cases, when the device does not respond to standard actions. Before returning the default settings, it is advisable to acquire backup, because user data will be lost. Enter this mode can be done as follows:
- turn off the device;
- press and hold the "Home" button;
- without releasing the button, we connect the iPhone to the computer using the original cable;
- evidence that the smartphone has switched to 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 the service center is inevitable. The most common cause of error 1 (-1) is the failure of the modem, 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.
Modem malfunctions are also indicated by violations in Wi-Fi operation and Bluetooth, but in order to completely determine the cause of error 1, diagnostics are needed. You can also try to flash your smartphone by removing the battery or just the board, in some cases this eliminates the problem.
