The iTunes application allows the user to restore the iPhone to the backup state or reset all settings to the factory settings after a critical failure or unsuccessful system update. Conducting a rollback is quite simple, since the general algorithm of actions consists of only two steps:
- Reset smartphone to factory settings;
- Restore user data using backup.
The nuances of recovery
Before you start restoring an iPhone, you should remember:
- Only the current and licensed (must be signed by Apple) firmware version can be restored. So, the user of the fourth iPhone with the version of the system 4.2.1, which has long been outdated, will not be able to roll back through Aityuns. The application will give an error that cannot be missed;
- This moment is for people whose iPhone is locked. When upgrading the firmware version, the modem version is also likely to increase. For such phones, before starting the rollback, it is recommended to use the Redsn0w program;
- If the owner has not made a backup of the state of the system, then upon restoration all user parameters will be reset to the factory settings. This will lead to the loss of all data on the iPhone.
After all the nuances are taken into account, we can proceed to the consideration of instructions on how to restore iPhone via iTunes.
Restore factory settings via iTunes
First of all, iPhone must be connected to a personal computer with Internet access, so that the device downloads all available updates, and launch iTunes. Next we follow the algorithm:
- We go to the "Overview" section, look for and click the "Restore iPhone" button:
- A confirmation window will pop up. It will also describe all the consequences of a rollback, such as the complete removal of media files and other information.
After the user agrees, the rollback procedure will begin. The process can last from 5 to 20 minutes. As soon as the recovery is completed, the iPhone will reboot with the factory settings, which means that all data is erased.
Restore data from backup
If a serious malfunction occurred during operation, which significantly reduced the performance of the device, and you had to reset it to the factory settings, then all files can be restored from a recently created backup.
- Turn on iTunes, connect the smartphone to a personal computer and put the iPhone in recovery mode;
- Go to the file section or call this menu using the ctrlB buttons;
- In the device section, select the option to restore files via backup:
After confirmation by the user, the file recovery procedure will begin.
Possible errors when restoring iPhone via iTunes
Often, when recovery is accompanied by errors. Most often two come up: 3194 and 1013 (the latter is connected with locked iPhones).
To fix the failure under code 3194, there is an algorithm:
- We launch the My Computer folder and look for hosts;
- Using notepad or WordPad, open the found file;
- Using the search string called by the ctrlF key, or manually search for the inscription gs.apple.com, delete it and save the document:
The way to fix the error with code 1013 (during all actions, the iPhone must be connected to the computer):
- Download the redsn0w application from the official site;
- Run the program as administrator;
- In the window that appears, click Extras and then Recovery Fix;
- Click Next. On the smartphone, in accordance with the instructions in the utility, set the DFU mode.
Of course, these two failures during recovery are not the only ones, but it is with them that users encounter the most often.
Following the instructions above, you can easily restore iPhone through the iTunes program without losing a single important file. For a more visual aid, you can watch a video that details the rollback procedure using the iPhone 5 as an example:
