Error 4005 when restoring and updating iPhone

Most often, the service centers for repairing smartphones are turned to the owners of iPhone 4S, who complain about problems with the firmware. As a result, an irreplaceable gadget either does not turn on at all, or an error appears on the screen. Often, such breakdowns may not lead to the most pleasant consequences: loss of all personal data or complete failure of the phone (in this case, recovery is impossible).

There is a huge number of reasons for such trouble. It is possible that there was a loading error or the user tried to install third-party software on the smartphone. Also, a frequent cause of breakdown is a hardware failure, which can be caused by mechanical damage or moisture ingress into the iPhone 4S.

However, this does not mean that in order to "resuscitate" the smartphone, you need to spend money on expensive diagnostics. There is a chance to fix your phone by yourself.

So, most often users encounter an unknown error of 4005. Let's consider the possible reasons for the appearance of such an inscription and methods for solving the problem.

Security Errors

On cell phones, as well as on laptop computers and tablets, antivirus programs, firewalls, firewalls and other utilities are often installed to protect the user's data. However, if you reflash or restore iPhone, this software can perceive manipulation of the phone as an attempt to download the virus software into it. In this case, very often on the screen there are various errors (4013, 9, 4005 and others), indicating a communication failure. To avoid trouble, at the time of updating the device, you must disable all programs of this type.

Problems with connecting iPhone to USB

The cause of 4005 error may be a problem with the USB cable. This is also evidenced by codes 9, 13, 1600, 1643 and others. In this situation, the most logical solution is the change of the wire. If the problem persists during reconnection, it is necessary to check the settings of the anti-virus software, possibly, they prohibit the connection of third-party cables. It is also recommended to restart the iPhone and disable the firewall and firewall for a while.

Synchronization issues

Quite often error 4005 occurs during the synchronization of iPhone, iTunes and the computer. This is due to the fact that during the download of the data packet, some of the required files are lost, and the software is not updated completely.

In this situation, there is no need to panic, since such a problem is considered to be the simplest, with the solution of which any user will cope. The first thing to understand is that iTunes and iPhone were developed by the same company, so such failures can not lead to irreparable consequences in the form of a significant disruption of the device's performance. It's also not to blame the developers. IT-technologies represent a whole set of functions that need to be realized in a tiny device. Therefore such failures are quite normal costs. If the iPhone screen error is 4005, then you can perform a few simple manipulations that will help restore the iPhone without losing data.

Method 1: Reboot

Before applying for qualified help, it is worth trying the simplest method for solving most problems. If the error occurred during synchronization of several devices, then you need to restart both the iPhone and the PC. Usually computers restart themselves, and the iPhone has to be turned off and on in forced mode. To do this, it is necessary to simultaneously hold the power button and the "Home" button and wait about 10-15 seconds. After this time, there should be a sharp disconnection of the smartphone. After that it is enough just to wait for the full load of the device and check if the error 4005 has disappeared.

If the problem persists, then the time has come for more serious actions.

Method 2: Update iTunes

If the old version of the media player is installed on the smartphone, then this can lead to similar problems. To resolve them, you need to check iTunes for available updates. If they are, then you need to install them. However, it should be taken into account that you can download any software only from the official site of the device manufacturer, in this case we are talking about Apple.

Method 3: reinstall iTunes

If even after the procedure for updating the media player, the 4005 error continues to flaunt on the screen, then this may be caused by communications failures. The only solution in this situation is a complete reinstallation of iTunes. To do this, you must first completely remove the program from the phone. And you need to capture not only the "media combine", but also other components of Apple. This will help additional utilities that allow you to remove the entire software.

Then you can install iTunes again.

Method 4: Change cable

It was already written about the replacement of the USB wire earlier. However, it is worth taking into account several other features of the error caused by the cable. In some situations, the wire may just be damaged. Nevertheless, even certified cables from Apple can not work properly. Therefore, it is worth trying a few different options before excluding such a cause of failure.

Method 5: Recovery via DFU

If all the above methods were powerless, and on the iPhone screen, the error 4005 did not disappear anywhere, then you can risk and restart the device in a special emergency mode of DU, which was developed by Apple in the event of serious software failures of smartphones.

To do this, you must perform several steps:

1. Disconnect the iPhone.
2. Connect the device to the computer using the USB cable.
3. Launch the iTunes media player on your PC.
4. Press on the smartphone first the shutdown button for 3 seconds, and then, without releasing it, click on "Home". Hold the key combination for 10 seconds.
5. Release the shutdown button and keep "Home" until the iPhone finds a media player.

After that, a message should appear on the screen, in which you will be asked to perform the recovery procedure. At the end, the problem should be solved, but in this case, most likely, there will be a complete loss of the latest data.

After the completion of all manipulations, it is recommended to perform a full scan of the iPhone and the computer for viruses.

Summing up

The article described the most common and effective methods for solving the recovery error, but this does not mean that they are guaranteed to work. If the problem is related to the software part, then the device is most likely to "revive" itself. But in cases where the hardware breakdown is the cause of the breakdown (for example, a failed battery), only a specialist who will diagnose and accurately find out which unit is in need of repair will be able to help.
