There are a few reasons you may need to wipe your iPhone 4. Wiping the device erases all of the data and settings and restores it to factory default settings. This can be useful if you are selling or giving away your iPhone and want to remove all personal information, if your iPhone is having performance issues that you think may be software-related, or if you simply want to start fresh with your device.
A complete wipe will delete everything on your iPhone 4, including:
- Contacts
- Photos
- Music and other media
- Apps
- SMS text messages
- Call history
- Safari browsing history
- Wi-Fi settings and passwords
- Account settings
So before wiping your iPhone, make sure to back up any data you want to keep. You can back up data and settings to iCloud or to your computer using iTunes.
When to Wipe an iPhone 4
Here are some of the most common reasons to wipe an iPhone 4:
- You’re selling or giving away your iPhone – Wipe it to delete all personal data.
- You’re experiencing performance issues – Wiping can help eliminate any corrupted files or software issues.
- You forgot your passcode – A wipe will reset the passcode so you can access the device again.
- You want to start fresh – Wiping the iPhone erases everything and resets it to factory settings.
Wiping your iPhone should typically be the last troubleshooting step you take if you’re experiencing issues with the device. It will delete your data, so only wipe your iPhone if you’re sure you want to reset it to factory default settings and have a recent backup.
How to Wipe an iPhone 4
There are a couple different methods you can use to wipe an iPhone 4. The easiest way is to use the “Erase All Content and Settings” option in the iPhone settings.
Here are the steps to wipe an iPhone 4:
Using Erase All Content and Settings
1. Open the Settings app on your iPhone 4.
2. Tap General > Reset.
3. Tap “Erase All Content and Settings.”
4. Enter your passcode if prompted.
5. Tap “Erase” to confirm and erase all data. This process can take several minutes to complete.
6. When finished, you’ll be prompted to set up and activate the iPhone again.
Using Restore in iTunes
You can also wipe an iPhone 4 by connecting it to a computer and restoring it in iTunes. Here’s how:
1. Connect your iPhone to your computer via the USB cable. Open iTunes if it doesn’t launch automatically.
2. Select your iPhone in the list of devices in iTunes.
3. Under the Summary tab, click “Restore iPhone.” This will install the latest iOS version and erase all data.
4. A confirmation popup will appear. Click “Restore” to proceed. The restore and wipe process will now run.
5. When finished, you can activate and set up your iPhone 4 as a new device.
No matter which method you choose, the result is the same – all data and settings on your iPhone 4 will be erased. Be sure you have a recent backup before wiping your device in case you ever want to restore any of the deleted data.
What Exactly Gets Deleted When You Wipe an iPhone?
Wiping your iPhone 4 using either the Settings reset or restoring in iTunes will delete:
- All contacts
- Text/iMessages
- Call history
- Safari bookmarks and history
- Notes
- Calendars
- Reminders
- Photos
- Videos
- Music
- Apps and their data
- Home screen layout/folders
- Touch ID and Passcode
- Wi-Fi settings and passwords
- Bluetooth pairings
- Apple Pay cards
- Location settings and history
- Notification settings
- Keyboard dictionaries and settings
- Siri history
Essentially, everything that makes your iPhone your own is erased. It will be like you just purchased and powered on the iPhone for the first time.
Some things that are NOT deleted when wiping an iPhone 4:
- iOS version number
- Media synced from iTunes (music, movies, TV shows, books)
- iTunes and App Store accounts
- Apple ID
- iCloud account and keychain
So content imported from iTunes and any accounts will remain and can be accessed after the wipe if you use the same Apple ID.
What About Deleted Photos?
When you wipe your iPhone, all photos stored on the device are deleted. This includes photos that were previously in the “Deleted” folder. Anything you manually deleted from your Camera Roll will be permanently erased by a wipe.
However, any photos you backed up to iCloud or your computer will remain safe and can be synced back to your iPhone later if desired.
Back Up Your iPhone Before Wiping
It’s highly recommended to back up your iPhone 4 to either iCloud or your computer before wiping. This will preserve your data in case you ever want to restore it later.
Here are ways to back up an iPhone 4:
- iCloud – Enable iCloud Backup in Settings > Your Name > iCloud > iCloud Backup. Then connect to Wi-Fi and tap “Back Up Now.”
- iTunes – Connect your iPhone to your computer via USB and open iTunes. Select your device and go to Summary > Back Up Now.
Backups save your device settings, app data, messages, photos, and other information. After wiping your iPhone 4, you can then restore from a backup during setup to return your data to the device.
Encrypted vs Unencrypted Backups
iCloud backups can be encrypted for added security. Encrypted backups protect personal information like your saved passwords, Health/Fitness data, and Wi-Fi settings.
To enable encrypted iCloud backups:
- Go to Settings > Your Name > iCloud > iCloud Backup.
- Tap “Back Up Now.”
- Tap “Encrypt iPhone Backup” and enter a password.
- Tap “Back Up Now” to run an encrypted backup.
You’ll need this password if you ever want to restore from the encrypted iCloud backup in the future.
How to Restore from a Backup After Wiping iPhone 4
Once you’ve wiped your iPhone 4, you’ll be prompted to set it up as a new device or restore from a backup.
If you want to restore your data from a backup, follow these steps:
Restore from iCloud Backup
1. Start the setup process and select your language. On the Data & Privacy screen, tap “Restore from iCloud Backup.”
2. Sign in with your Apple ID and password.
3. Select the desired backup. Tap “Restore” to confirm.
4. Your iPhone will reboot and restore from the iCloud backup. This can take several minutes.
Restore from iTunes Backup
1. Open iTunes on your computer. Connect the wiped iPhone 4 via USB.
2. A prompt will say there is a backup available and ask if you want to restore. Click “Restore” to proceed.
3. Select the backup you want to restore from. Click “Restore” again.
4. iTunes will now restore your selected backup to your iPhone 4. Let the process complete.
Once the restore finishes, your iPhone 4 will reboot and you’ll have your data back! You can repeat this process to restore different backups as needed.
Other Options for Transferring Data to a Wiped iPhone 4
Besides restoring a full backup, you have a couple other options for getting some data back onto a wiped iPhone 4:
- Sync from iTunes – You can sync iTunes content like music, movies, books, and photos to your wiped iPhone 4.
- iCloud Sync – Enable iCloud settings like Contacts, Calendars and Photos to restore data from iCloud.
- Sign in to Accounts – Sign into your iCloud, Email, and Social Media accounts to restore account data.
- Google/Microsoft Sync – Use Google or Microsoft sync to restore Gmail, Contacts, Calendar events, and other data.
The most convenient way to restore your apps and data is from an iCloud or iTunes backup. But if you only need to transfer certain information, you can set up selective sync instead of a full restore.
Troubleshooting: iPhone Won’t Restore from Backup
If your wiped iPhone 4 won’t restore from a backup, here are some things to try:
- Make sure your iPhone is connected to the internet via Wi-Fi to restore an iCloud backup.
- Check that you have enough storage space on your iPhone for the backup.
- Double check that you’re signed in with the same Apple ID used to create the backup.
- Verify the date/time on your iPhone is correct, as incorrect settings can prevent restore.
- Update to the latest version of iOS if you haven’t already.
- Restart both your iPhone and the computer you’re restoring from.
- Try a different charging cable if you’re restoring from iTunes.
- On your computer, make sure iTunes is authorized and has the latest version.
- Reset network settings on your iPhone under General > Reset.
If you encrypted your backup, make sure to enter the correct password when prompted. Otherwise the iPhone won’t be able to restore from that backup.
If you still can’t get your iPhone 4 to restore, you may need to delete the backup from iCloud or iTunes, then make a fresh backup and try restoring again. Contact Apple support if you continue having trouble.
