Error 1 when restoring iphone 5c. What to do if the iPhone is not flashing and gives an error

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 on different ways to solve 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. Using Recovery Mode, try to restore the firmware via iTunes to the factory one.

Hardware malfunctions leading to error 1 iPhone

Faults:

1M odema

2. Power Controller modem unit (U2_RF)

3.eeprom (U6_RF)

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 flashing processreaches about 60% and then gives an error 1 just inthe beginning of the modem firmware or at 99%.

The network disappears and a constant search for the network begins

Wi-Fi periodically becomes inactive (switch inactive)

• IMEI does not show through * # 06 #

• 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.

The A7 processor is highlighted in red, the Qualcomm MDM9615M LTE modem is highlighted in orange, the Qualcomm WTR1605L LTE/HSPA+/CDMA2K/TDSCDMA/EDGE/GPS transceiver universal module is highlighted in yellow.

4. You can restore via iTunes when an error occurs at 60 percent, remove the back cover and temporarily open the battery terminals and then try to flash again.

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 a mobile gadget and one cannot do without going to a service center. However, there are isolated cases when it is possible to revive a mobile phone at home.

Causes of Unknown Error -1 iTunes

• Using an uncertified cable, a person puts himself at risk, because the number of system errors can be increased many times due to 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 restoring iphone 5s, the device often lost connection, even in places where the signal strength was good before, error -1 appears only at the end of the update process, the smartphone fell or moisture got into it - these are all signs, which indicate that the modem was broken in the iPhone 4S, 5S device.

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 deal exclusively with the replacement of 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 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.

During operation, there are unpleasant moments when error 1 may occur when restoring iPhone 5s and iPhone 5c. With this in mind, a lot of questions arise regarding the causes of occurrence and ways to eliminate them. First, you should determine the cause of this problem on the top five.

Cause of error in i Phone 5s

It should be noted that if error 1 is generated during recovery or an unknown error has occurred, it is advisable to visit a service center, your mobile operator, who will help restore your iPhone to working order. It is especially important when error 1 occurred for the first time.

iTunes Error 1 Warning is likely due to the following:

• the presence of a program failure that may occur during the process of restoring or updating the device;
• the process of violation of the activity of the model module.

The first option is probably very easy to solve on your own. For the most part, this very often happens when flashing iPod, iPad, iPhone. This may be a consequence of installing the most updated firmware version on your device, relative to the previously installed one. Or, most likely, this version does not correspond to a certain model of the device, and iTunes is also not suitable. If the problems with the error warning 1 are due to a possible software failure, you can solve this problem yourself.

Actions taken to eliminate the consequences of a software failure:

• it will be necessary to control the full compliance of the firmware version that is installed with a specific device;
• the specific version of iTunes must match the previously installed IOS variant;
• using Recovery Mode, restore the iTunes firmware to the factory.

As a rule, the method of following the above suggestions will help restore the iPhone to working order. If error 1 continues to appear, then this is a malfunction of the model module. Then you will need to visit the service center. The occurrence of an error, very often, can lead to a violation of the Wi-Fi connection, as well as Bluetooth. It was then that problems with these systems are the most likely modem failure.

To establish the most correct diagnosis, it will be necessary to conduct a diagnostic examination of the device in a service environment. Thanks to the use of innovative testing equipment, there is an excellent chance of determining the most likely cause of breakdowns. If the system module is damaged, it will need to be replaced, with the replacement of the motherboard, which makes it necessary to use modern specialized equipment.

Ways to fix error 1 in iPhone

Procedure for troubleshooting:

• close and reopen iTunes (if it was open);
• check the installation of an updated version of iTunes on the device;
• make sure that there are no possible problems with a third-party program designed to ensure security;
• check the operability of the wires and the computer network itself;
• try to restore the device iPod, iPad, iPhone;
• if you receive a signal about the presence of error 1, upon completion of all the listed measures, it is necessary to check for the installation of an outdated version of the software on the computer.

When installing a new version of iTunes Windows, you will need to open the iTunes program and the menu (it will be located at the top of the iTunes window), select "help" and "check for updates." Then install the new version. On the Mac system, also open the iTunes program and the section - "check for updates" with the installation of the latest version. If the system does not prompt you to install the latest version of iTunes, this may indicate that a new version is already available, with support for the operating system. To start this operation, you need to familiarize yourself with the system requirements for new programs on the iTunes download pages.

If you need to restore the factory settings, while simultaneously deleting the data of the old settings, you should install the latest version of IOS. For these purposes, you need to prepare the device - make sure you have the latest version of iTunes and create a backup, then turn off the "Find iPhone" function in the settings.

Factory reset process:

1. Provide iTunes access on Mac, PC. If there is no access, delete data and restore the device without a computer.

2. Connect your iPod, iPad, iPhone to your computer with a wire.

3. Enter the password for the device.

4. Select the most suitable device when it is displayed in iTunes.

5. Go to the tab - "overview" and click the section - "restore device".

6. To confirm, press the “restore” button again. With iTunes, the unit will be cleaned and the latest version of iTunes or iPod software will be installed.

After all factory settings have been restored, the machine will be restarted so that it can be set up as a new sample.

Troubleshooting third-party programs

If you need to open the iTunes system, the unit will not synchronize and you will not be able to download content. It is also possible that there is a security software bug that could prevent iTunes from connecting to a particular Apple service or device. This may appear when updating, synchronizing, performing backups and restoring the device.

Signs of conflicts between the software and iTunes may include the following factors:

• recognition is not performed in iTunes, in such devices as iPod, iPad, iPhone, with the inability to backup, update, restore, activate various applications;
• there is no process of connecting to the iTunes Store to make a purchase, download content;
• inability to open iTunes.

To ensure the start of work and the ability to change the software parameters, it is necessary to carry out a number of the following activities:

1. Make sure that the date, time and time zone are set correctly.

2. Visit the administrator account.

3. Make sure you are using the latest version of iTunes.

4. Carry out the process of updating OS X (OC Windows).

In cases where all of the above actions did not bring the expected result, it will be necessary to monitor the health of the connection. To do this, you should check the hosts file and make sure that there is no blocking of the exchange of information between various Apple servers and iTunes. If the AirPlay function and the “home sharing”, iTunes, “remote control” function fail, check the connection between your device and the computer. Both devices must have one common connection to the network or subnet. If these actions did not help in solving this problem, you should check the security software. In such a case, the security software will interfere with the iTunes program. Sometimes unforeseen situations arise when it may be necessary to temporarily remove it in order to conduct an accurate analysis of the cause of the problem. Some types of Internet security programs will not completely remove them and to completely remove them, you will need to download and run a cleaning utility.

If you need to open access to various services or to provide certain assistance during the operation of the iPhone related to the removal of software, you should contact the services of security software. The same reasons are typical when error 1 occurs on the iPhone 4s. There is only one error in the iPhone 4, it is eliminated in a similar way. If unforeseen circumstances arise during the elimination of error 1, you must contact the service center.
