Sometimes Code 1 blue screen errors related to hardware can be caused by damaged random access memory(RAM). If you are experiencing random computer reboots, sound signals When booting or other computer malfunctions (in addition to BSOD 1 errors), it is very likely that there is memory corruption. In fact, almost 10% of application crashes on Windows OS are caused by memory corruption.
If you have recently added new memory to your computer, we recommend temporarily removing it to make sure it is not the cause of the Code 1 error. If this action clears the BSOD, then that is the source of the problem, and therefore the new memory is either incompatible with some other device. either your equipment or is damaged. In this case, you will need to replace new memory modules.
If you haven't added new memory, the next step is to conduct a diagnostic test of the existing computer memory. A memory test scans for serious memory failures and intermittent errors that could be causing your blue screen death 1.
Although the latest Windows versions contain a utility for testing RAM, I highly recommend using Memtest86 instead. Memtest86 is a testing tool software BIOS-based, unlike other test programs run in Windows environment. The advantage of this approach is that the utility allows you to check ALL operating memory for Code 1 errors, while other programs cannot check memory areas occupied by the program itself. operating system and other running programs.
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 promise anything good devices. Many of the failures occur for software reasons and can be fixed quite simply, while others indicate hardware faults and require a more serious approach to treatment (often not without financial investment). The code assigned to each error helps you get closer to the solution by revealing possible reasons problems, but still unable to determine the “root of evil” with 100% 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 an 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, damaged firmware files, incorrectly created assembly, etc., and in the worst case, by 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 device elements are much higher if the iPhone has previously been subjected to falls, shocks or other mechanical damage, water has entered 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 problem yourself using simple solutions. The key to successful iPhone synchronization 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 the physical connection between the devices is complete and the USB cord does not come loose. 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 reboots into standard mode, and the iOS device is in forced mode.
Method 1: Replacing the cable, using a different USB port
It is possible that error 1 was caused by damage to the cable or the use of a non-original one. If any defects are found during inspection, even minor ones, 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 make the connection directly, without using those 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 it on another computer.
Method 2. Disabling the antivirus
Method 1 of disabling security software helped many people fix error number 1. If the failure occurs as a result of a conflict between defender programs and iTunes, which often happens, then you need to disable the antivirus, firewall or firewall while performing the update or firmware recovery procedure. If error 1 does not happen again, add iTunes to the list of exceptions in the settings of antivirus programs.
Method 3. Using different firmware
Failure with code 1 when working with iPhone 4, 4s, 5, 5s and other Apple devices 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 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 correct operation program, it must be updated to the latest available version. It is possible that the appearance of error 1 in iTunes is caused by an imbalance between the program and the firmware. It is recommended to check for updates and, if necessary, refresh iTunes. If the method does not work, reinstalling the application can save the situation, which means complete removal iTunes and all its accompanying components. After uninstallation, you must restart your computer and install latest version programs.
Method 5: Run iTunes in Compatibility Mode
Often the problem is resolved by running the program in compatibility mode for the selected operating system. To do this, perform the following steps:
- right-click on the iTunes shortcut to bring up 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 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 available updates For current version OS and their installation. You can use the option from 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 intended for Apple devices in severe cases when the device does not respond to standard actions. Before returning the default settings, it is advisable to have a backup copy, as 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 button, connect the iPhone to the computer using the original cable;
- evidence that the smartphone has entered Recovery Mode will be an image of the iTunes icon and the USB cord;
- We launch the program, where you can see that the emergency recovery mode is running.
If you fail to revive your iPhone at home, a trip to a 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 also to blame. It may be necessary to solder or replace parts, which is best done in a service environment by the hands of professionals.
Malfunctions of the modem are also indicated by disturbances 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 your smartphone by removing the battery or just the board; in some cases this solves the problem.
A person quickly gets used to good things and, having found this good thing, does not strive to look for a replacement for it. This is exactly how I can describe my situation with the iPhone 3GS smartphone. I understand that in the era of the iPhone 5S, you won’t surprise anyone with this miracle technology, but for me it’s just handy tool, which absolutely everyone likes and I had no intention of changing it.
For a long time I had to live without an Apple smartphone, and today I brought my “friend” back to life. The mistake was fatal for many - Error 1(-1), but as it turned out in my case, it was fixable. Perhaps my story will be useful to someone. At least I really hope so.
iPhone phone The 3GS came to me completely by accident and somehow took root very quickly. During operation, I picked up everything for myself required application, some I bought, some I found from the list of free ones. It’s like a favorite Japanese car, it seems to be old, but it’s so familiar and you don’t want to change it. Same with this phone.
At my core, I am a person who can easily take a screwdriver and get inside any complex device. It was like that with, and it was like that with every laptop. This is not because I know in advance what I will see there and immediately have a plan in mind further actions. No!! I just have a higher threshold for fearlessness. Although, perhaps, many IT specialists can boast of this. It was this fearlessness that pushed me to solve the problem of replacing the battery on my iPhone myself. Without hesitation, I went to Ebay and ordered a battery. As a result, after waiting 45 days, I did not receive it, I returned the money from the seller and ordered from another. A month later, I finally received the battery and took a screwdriver in my hands and took the iPhone apart.
It turned out to be quite easy to disassemble. Replacing the battery was even easier. After 2 hours of work, I received my iPhone with an updated battery.
After replacing the battery, I thought, why not completely change the case, which over time had already become quite worn out and did not look quite presentable. In solving the problem, Ebay again saved me. After 45 days I received from China new building(it turns out that parcels to Omsk take no less than 45 days, and sometimes even more), which, to my surprise, was absolutely no different from the original one. Perhaps they have no differences at all. :)
After 40 minutes the case was replaced. The phone turned into a new one again. My joy simply knew no bounds.
Unfortunately, all good things tend to end unexpectedly. This happened to me when I once again connected my phone to iTunes installed on my work computer. After synchronizing, iTunes for some reason independently decided that I needed to restore from some kind of backup. Before I had time to come to my senses, after restoration the phone turned into a brick (as the gurus say, “hanging by a cord”). What did I not do with him? Starting from a simple recovery and ending with upgrading the modem to an iPad and downgrading it back. There was only one result - Error 1(-1).
There is not much written about this error on the Internet. The only solution that is offered is to solder the modem to a new one and further pervert by slipping someone else's imei and installing a jailbreak. For me, this development of events was completely utopian and I threw the phone into a distant IKEA box.
Probably a month later, one autumn evening, my girlfriend and I were sorting out boxes and my broken iPhone caught my eye. I decided to change it again just in case. I simply connected it to the computer and waited until the phone recharged and turned on on its own, I started the standard recovery process. I didn’t have much hope for any miracle, but a miracle, oddly enough, happened. The phone was successfully flashed and came to life. After that I rolled backup copy from iCloude and began to enjoy life.
The next day at work I connected it to iTunes and this bastard again, taking advantage of my forgetfulness, downloaded his backup copy. As a result, the phone again went into permanent recovery mode and error 1(-1). After torturing the phone a little, I put it back in the box.
After some time, I received my first battery from Ebay (this happened as much as 3 months later), it dawned on me: the phone was successfully restored only after the battery was completely discharged, which means that there is a possibility that the problem lies precisely in it. In addition, I once read that Apple came up with some kind of cunning system in which the device collects all the information about itself and stores it for its entire life. If something breaks and a person does not repair the breakdown in an authorized Apple center, he will face big hemorrhoids with bypassing this tricky system. Thanks to her, after resoldering the modem, people had to install a jail and only after that the phone began to work normally. By the way, the battery I received turned out to be very similar to the original one.
Without hesitation, I once again disassembled my phone and installed a new battery. After running the restore via iTunes, the phone was successfully restored. Error 1(-1) is gone.
This is how improper battery operation led, although not immediately, to the failure of the phone and error 1(-1). A simple battery replacement helped bring my “friend” back to life.
The most annoying thing about this story is that the new battery lasts exactly the same amount as the old, original one. This is the paradox of life.

There may be cases where users iPhone smartphones or tablet computers iPads encounter error -1 when connecting to iTunes. A lot of questions immediately arise: what kind of error is this, what caused it, how to eliminate it, etc.? We will help you find out the cause and effect of this error, and also tell you what to do to fix the problem.
If you want to quickly and easily get rid of the problem, we recommend that you contact our service center MobRemonte r, where experienced professionals will find the cause of error 1 and get rid of it in a short time. But first, let's determine the reason for this error.
As the practice of our service center shows, this warning about error 1 in iTunes can occur for two reasons:
- Software firmware failure.
- Malfunction of the modem module.
In the first case, solving the problem is very simple. As a rule, this happens when updating an iPhone or iPad. Surely you tried to install more earlier version firmware than was already installed and did it on an inappropriate device or inappropriate iTunes. If the problems and warning with error -1 are really related to software glitch, then you can solve the problem yourself. To do this you need:
- Check version installed firmware and its compliance with your device.
- Check the version of iTunes and its compliance with the installed iOS.
- Restore to factory firmware from iTunes using Recovery Mode.
By following these recommendations, you can return your iPhone or iPad to normal working condition if error -1 was caused by a software glitch. But if, after following the recommendations, error -1 continues to appear, then most likely the problem is a malfunction of the modem module and in this case, you need to urgently contact a service center.
Often, if the modem malfunctions, the Wi-Fi operation network and Bluetooth, so if such problems were noticed, then the problem is definitely a failure of the modem part. To finally and definitively verify this, it is necessary to carry out a diagnostic examination of the device. To do this, our specialists use specialized testing equipment, which will allow us to accurately determine the cause of the breakdown. If the modem is damaged, the module will need to be replaced or motherboard. This is a very complex technical process that requires professional skill and specialized equipment, so don’t even try to fix the problem yourself, but entrust it to the highly qualified specialists of MobRemonter. We will bring your gadget back to life in the shortest possible time.
Let's consider our options for dealing with this error. First, let's determine what causes -1(1) error when updating iPhone. The sad news right away is that, as a rule, this problem is directly related to a faulty unit in the device, and specifically to the modem. We will consider options for 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 us from flashing an iPhone via iTunes. For some iPhone -1(1) owners, the error appears due to:
1.Uses “gray” non-certified wire (you need to use the original cable)
2. Installed outdated iTunes versions on your computer (you need to download the new version of iTunes)
3. Other iPhone users may benefit from running iTunes from administrator name or in compatibility mode.
The problem is that these methods only help 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 modem failure. You can determine this by the following signs:
1.Shortly before the appearance errors -1(1) The phone worked unstable, from time to time it lost the network, and then found it, and this happened even with reliable signal reception.
2. During the device recovery process, the error appears only at the last stage, when the process is already coming to an end.
3. The battery was updated or another type of intervention was made to the device.
4. Water ingress, phone falling
5.A window appears with error -1(1) in iTunes
If you allow any of these options, then be 99% sure that error -1 in your case is associated precisely with damage to the modem.
We determined that the modem was at fault. Let's consider options for further action:
1. The right way solutions errors -1(1).
This is the most reasonable option. You need to visit our service center. If the phone is under warranty, don't hesitate, take it to an official service center apple center. Considering the feature errors -1(1) appear due to mechanical stress, you should be prepared for the fact that you may be denied free official repair, but we strongly advise you to try.
If the warranty has expired, then we begin to carefully choose a service. Service center specialists must have the necessary skills and special tools to properly solder your modem. We strongly advise against going to the market stall; at best, you will get your phone back with the same error; at worst, you will have to repair something else.
Therefore, if you decide to contact the service, choose trusted places with recommendations and a guarantee of quality.
Let's consider a treatment option -1(1) errors without re-soldering the modem. This can be done in any workshop, but you can try to do it yourself, saving yourself money.
2. Incorrect method, but it works in some cases.
It is incorrect because we strongly do not recommend doing this to your device. But since there is an option, we will consider it.
Be careful! You take responsibility for all consequences! If there is a guarantee, after these manipulations, you can forget about it. There is a chance of damaging the phone even more and damaging 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 a phone with an error through iTunes and revive it. Then you can use it, for example, as an iPod, but this will not help restore the modem and it is better not to count on the iPhone being able to reliably use the cellular network after this.
Then consider the actions:
1. Freeze iPhone. A freezer, a refrigerator, maybe it will help you with this in winter. Don't forget to pack the gadget in a plastic bag. Leave it for 15-20 minutes in a selected cold place and then try to flash the iPhone through the program iTunes. Someone flashes a phone without taking it out of a cold place. Whatever you think about us now, this helps someone to flash their device to the end.
2. Warm up your iPhone. It is best to heat the modem directly and use special equipment for this, this will help avoid overheating. Then try to flash the iPhone while it is still warm. 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 your 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 things. Just very carefully.
Even if you managed to complete the restoration or update of the iPhone, then most likely you will still have an iPod in your hands - it will not be able to catch the network, and even if it can, it will be unstable. But you might get lucky...
Still, -1(1) error is quite serious.
Today we told you about all the solutions errors -1(1). It’s up to you to decide which method to choose, but if you want not only to revive your phone, but also to make it work fully, then our service center is at your service. We will solve this problem as soon as possible.
