Reinstall iPhone - Here's how

If you have persistent problems with your iPhone, it often helps to re-set the iOS device. It's easy with iTunes: you can either import a backup or - if that doesn't help - reset your iPhone to the factory settings.

1st possibility: Set up iPhone again via iTunes

1. When restarting, the iPhone is reset to the factory settings, the operating system (iOS) is reloaded and - if desired - you can immediately restore your backup to the device. However, an inserted SIM card is absolutely necessary.
2. Start iTunes and connect your iPhone to the PC with a USB cable.
3. Select the device in iTunes and make a backup copy of your data under "Backups" by clicking on "Back up now".
4. You can backup your apps separately using the "Backup apps" option.
5. Then click on the "Restore iPhone" button in the overview and confirm the process in the next window by clicking on "Restore".
6. After the process is complete, you can import your backup or configure the device as a new iPhone.

Option 2: Replace iPhone directly on the device

1. Alternatively, you can set up your iPhone again without iTunes. However, you should also create a backup for this first.
2. To do this, open the settings and tap on "iCloud". Activate all displayed data and apps and select the item "Storage & Backup". Activate iCloud backup.
3. Tap "Back up now" to back up your data wirelessly.
4. Now select the "General" menu item in the settings and tap on the "Reset" option.
5. Click the "Delete content & settings" button and confirm the process.
6. After resetting, you can restore your iCloud backup in the configuration process.
