If you have persistent problems with your iPhone, it often helps to reset the iOS device. iTunes makes it easy: You can either make a backup or – if that doesn’t help – reset your iPhone to the factory settings.
1. possibility: reset iPhone via iTunes
- With a reset, the iPhone is reset to the factory settings, the operating system (iOS) is re-installed and – if desired – you can restore your backup to the device. However, an inserted SIM card is absolutely necessary for this.
- Start iTunes and connect your iPhone to the PC via USB cable.
- Select the device in iTunes and create a backup of your data under “Backups” by clicking on “Back up now”.
- You can create a backup of your apps separately with the option “Backup apps”.
- Then click on the “Restore iPhone” button in the overview and confirm the process again by clicking on “Restore” in the following window.
- On completion of the process, you can restore your backup or configure the device as a new iPhone.
2. option: re-set iPhone directly on the device
- Alternatively, you can also reset your iPhone without iTunes. However, you should also create a backup first
- Tap on “iCloud” and then on iCloud Backup.
- If you haven’t already done so, slide the slider to the right to activate iCloud Backup. Then tap on “Create backup now”.
- Once the backup has been created, go back to the settings and select the menu item “General”.
- Scroll all the way down to the item “Transfer/reset iPhone”. Tap this item and select “Erase all content & settings” in the next step. Note: Here you will also find the option “Reset”. However, if you want to restore the iPhone later with the iCloud backup, you must delete all content and settings.
- After erasing, the iPhone will start in the configuration process and you can restore your iCloud backup.
