This article describes the cases when the iPhone is not restored and what can be done if such failures occur.
In fact, there are many reasons for refusing to restore a gadget through iTunes. These can be both problems in the hardware of the device, and a banal outdated version that does not allow you to restore the iPhone through iTunes, the appearance of error 9 or an incorrect reset of all settings.

The fact is that if you use a non-original usb cable, then it will provoke a refusal to install the firmware. If everything is fine, but the process does not start, carefully inspect the wire and connector for damage.
Using a different usb port
Very often people connect the device through the ports located on the keyboard or other peripheral devices and are surprised that they cannot reflash the device. Try connecting your iPhone via a different USB port located on the back of the system unit.

After connecting the smartphone to the computer, use the USB port to restore iOS, if possible. Things are very bad, even if this method did not help.

Flashing options.
By flashing iOS devices, it is customary to understand two processes:
Update.
Recovery.

IPhone flashing can be done in two ways. Moreover, one of the methods is versatile, which allows you to use it for updating and restoring. Whereas the second way of working on a flashing is used exclusively for updating.

Differences between update and restore.
When carrying out work on the restoration and updating of the iPhone, work is performed with the software component of the device.
When performing a restore, iPhone returns the device to its original settings. All settings will be manually returned to factory settings, and existing content and personal data will be deleted from the smartphone.
A restore resets all existing settings to the factory state and installs the latest clean iOS version.
When updating a mobile gadget from Apple, the old version of the operating system is replaced with a newer one. At the same time, all personal data, settings and content remain intact and remain in the new version of the operating system.
As you can see, the difference between updating and restoring an iPhone is that the update does not delete personal data and content from the iPhone.
The developers of the iPhone smartphone have provided their device with the ability to work in several modes. This can be normal mode, firmware update mode, and recovery mode.

This will be true for owners of devices in which the jailbreak procedure is performed. The fact is that the jailbreak is not available for the latest versions of the operating system, so after updating iOS, you will invariably lose the jailbreak.

Why you need to back up to iTunes
It is necessary to create a backup of the contents of the phone for several reasons:
- In order to restore the firmware and operability of the device, if necessary.
- In order not to lose content in the event of an incurable breakdown or loss of the phone.
- When the unit is sold / transferred, its settings, contacts, programs and files can be transferred to a new device from a computer.
If you have automatic synchronization configured, a backup will be created by default every time you connect your smartphone. If there is no automatic synchronization, then the creation of a backup copy occurs at the user's command.
