"I want to update my iPhone to iOS 15, but it seems an error occurs and the update fails, should I do the restore iPhone to fix it?"
According to Apple, restoring iOS devices is part of standard isolation troubleshooting. In other words, it is indispensable for all iOS users. However, most users do not understand what restoring iPhones means and how to do the job properly. Therefore, this guide will explain the term and demonstrate how-to in detail.
First of all, restoring your iPhone will remove all information, data, and personal settings on your device. However, if you create a backup before the restore process, the backup can be used to restore all of your apps, music, settings, and more back to your handset.
In other words, restoring an iPhone means two actions, restore an iPhone to factory settings or restore a backup to your device. It is a significant functionality to do troubleshooting when there is an issue with your device that other solutions have not been valid. Both actions can achieve the goal. The former brings your iPhone to the original factory status, and the latter brings your handset to the last normal status.
Make sure that you have an iCloud backup. If you do not have a backup, create one. To restore backup to a new iPhone, follow the steps directly. For a used iPhone, you need to reset the device with the Erase All Content and Settings feature.
iCloud backup includes your iPhone settings, home screen layout, photos, videos, messages, app data, Visual Voicemail password, and Apple Watch backups.
If you just want to restore an iPhone to factory settings, iCloud can meet your needs too. The premise is that you have set up Find My iPhone on your device. Moreover, it is only available when your device is online.
Some people prefer to back up their iPhones with iTunes or Finder. Therefore, the app is another way to restore an iPhone from backup without erasing. Moreover, it is available to an accessible iPhone, an inaccessible device, and a new handset.
On an accessible iPhone, connect your device to your computer with a Lightning cable, and open iTunes. Click the Phone icon to detect your device.
To restore an inaccessible iPhone with iTunes/Finder, plug your device into your computer with a Lightning cable, and open iTunes or Finder. For iPhone 8 or later, press and quickly release the Volume Up button, do the same to the Volume Down button, and long press the Side button until you enter the Recovery Mode screen. For iPhone 7/7Plus, hold down the Side and Volume Down buttons at the same time until you see the Recovery Mode screen. On iPhone 6s or earlier, keep pressing the Sleep/Wake and Home buttons simultaneously until the Recovery Mode screen pops up.
If you intend to restore backup to a new iPhone, set it up and choose Restore from iTunes Backup on the Apps & Data screen. Then connect the device to a computer with a Lightning cable.
This way will overwrite the existing data on your iPhone with the backup. The content in an iTunes backup includes:
If you do not have a backup in iTunes or Finder, restoring your iPhone means erasing all content on your device and resetting it to the factory status. This action is often used to solve serious problems on an iOS device, such as system crashes. Bear in mind that that will wipe out all your data and settings on your device. Therefore, you'd better make a backup before the process. Plus, make sure to sign out Find My on your iPhone.
If a message asks for your device passcode or Trust This Computer, enter your passcode or tap Trust.
Instead of getting a backup, restoring your iPhone will erase all your data and install the latest iOS. When the process completes, your iPhone will restart and display the welcome screen like a new device.
As mentioned previously, both iCloud and iTunes have the capability to restore an iPhone to factory settings or with a backup. However, they all have some downsides. iCloud, for example, only provides 5GB of free storage capacity for each account. That is limited for most iPhone users. iTunes restores iPhones with a computer, but the workflow is quite complicated for average users. Moreover, iTunes is not working or detecting your device sometimes. Is it possible to restore an iPhone without iTunes or iCloud? The answer is Aiseesoft iOS Data Backup & Restore. As its name indicates, it lets you back up your iPhone to a computer, and then restore the backup at any time without technical skills.
