In this tutorial, we tell you how to reset your iPhone or iPad and how to restore your backed up data.

How to fix a frozen iPhone or iPad?

You will not escape THE question: “Have you tried turning your iPhone off and on again?” Even if it seems ridiculous, turning your iOS off and on again fixes bugs and improves the performance of your iOS or iPadOS.

For more serious technical problems, we advise you to make an appointment with the Genius Bar of an Apple Store.

Note that very often, repairing your iPhone with an Apple technician will involve deleting your data.

It is therefore vital that you back them up as regularly as possible.

What to do if your iPhone has crashed?

If your iPhone is unresponsive or won’t turn on again, don’t panic. There is a method that does not require any installation or special knowledge: that of force restarting your iPhone or iPad.

  • Sure iPhones 6 or earlier models, simultaneously press the Power button and the Home button until the Apple logo appears on the screen, and then release.
  • On iPhone 7 and 7 Plus, press and hold the Power button and the volume down button at the same time until the Apple icon appears, then release.
  • On iPhone 8, SE and later models, quickly press the volume button up, then the volume down button. Next, hold down the Power button until you see the Apple logo, then release.

If after this manipulation, nothing seems to change, then a full restore should be considered, from a backup.

How to backup your data before erasing everything?

As we mentioned earlier, before resetting your iPhone or iPad, it is essential to back up your data.

It is possible to do this either from your phone through iCloud, or from your Mac through Finder or iTunes.

From iCloud:

  • Go to Settings, sure [votre compte], then touch iCloud.
  • Activate the option ICloud backup. This allows you to automate backups of your data.
  • Press on Save now.

This is the easiest method, and only an internet connection is required.

From your computer:

Connect your iPhone, or iPad, to your computer. If your Mac is running macOS Catalina 10.15, or a later version, then open the Finder. If it’s macOS Mojave 10.14, or earlier, or even on a PC, open itunes. Then:

  • Once on Finder, or itunes, click on your iOS icon.
  • In the section Backups, click on Save now.


Delete apps and their data one by one

To delete your applications and data, go to SettingsGeneralStorage iPhone.

You will have access to a list of your applications and the storage space each occupies.

Note that it is not possible to remove Apple apps that are preinstalled (native), such as Apple Music or Photos.

To permanently delete an application:

  • Select it from the list.
  • Then press Delete the app.

You can also delete your apps from the home screen, to do this:

  • Tap and hold the app in question.
  • A cross appears, at the top left of the app, tap on it to delete it.

If there is no cross, it means that you cannot erase it from your phone.

How to reset your iPhone to factory settings?

Did you save everything? Then you are ready to restore to factory settings!

This method consists of a complete cleaning of your iPhone, which is why you should be sure that you have backed up everything.

Often a factory reset is necessary if your device freezes, malfunctions or is sold. Indeed, if you want to resell your smartphone, then you will have to clean it thoroughly to prevent your data from being accessible and thus “stolen” by a malicious buyer.

For a factory reset there are two methods:

  1. From your iPhone:
  • See you in Settings General Reset.
  • Select Clear content and settings.
  • Enter your code.
  • Select Erase iPhone.
  • To complete and confirm this operation, you will need to enter your Apple account password.


  1. From Finder or iTunes:
  • Connect your iPhone to your Mac.
  • On Finder or iTunes, click on your iPhone icon
  • In the General tab, go to the option Restore iPhone ….


Restore iPhone from backup

After you reset your iPhone to factory settings, and now that it’s like new, all you have to do is restore it with your latest iCloud backup.

First, you will need to configure it (choose your language, region, etc.), then restore options will be offered to you: Restore from iCloud, Restore via Mac or PC, Transfer from iPhone or Migrate data from Android.

Restore from iCloud

  • Select Restore from iCloud.
  • Enter your Apple ID and password, then agree to the terms and conditions.

The length of this process depends on the contents of your iPhone or iPad, and the speed of your Internet connection.

Also note that your iPhone does not restore your apps, but downloads their latest version.

Restore via Mac or PC

The process is the same as restoring from iCloud, with the same options.

  • Connect your iPhone to your computer.
  • From Finder or iTunes, click on your iPhone icon
  • In the tab General, select Restore backup.
  • Finally, enter the requested password, then wait for the process to complete.

What if your iPhone / iPad doesn’t have a backup?

If you didn’t have a backup, it’s quite possible that your iPhone made one without you knowing.

To be sure:

  • See you in Settings [votre compte] iCloud.
  • Press on Manage storage
  • Go to Backups, then on This iPhone.


There you will find the date and size of your last backup. You will also notice that it is possible to choose the data you want to save. This feature is very useful for managing storage space.

If necessary, you can always increase your storage space via the option: Change plan.

Is it possible to recover deleted data?

This is almost impossible, which is why it is essential that you make one or more backups before any deletion or cleaning of your iPhone.

Data stored on iOS is automatically encrypted and once you decide to delete it, their encryption key is also destroyed.

Their recovery without backup via iPhone is therefore very difficult if not impossible.

You can always go to Apple Genius Bar, but nothing is guaranteed …

Note that if your data has been deleted due to a malfunction of your device for example, their recovery is then much more possible.

To avoid this kind of situation, we can’t repeat it enough: backup, backup, backup.
