Backup the iPhone

Back up your iPhone's data to prevent data loss during this process.

Please watch the video below, which clarifies some important points. Then, proceed with the steps below in order.

Step 1: Check iCloud Sync Settings

To be sure your personal Photos and Videos are not lost when supervising your device, check iCloud Settings are correct.

On your iPhone, double-check your iCloud sync settings to ensure that you are backing up important data.

Go to Settings > [your account name] > iCloud > iCloud Backup.

Tap on See All to view current backup status for your Photos and Files

Verify that your Files, Photos, and Messages are being backed up.

Step 2: Create a Full Backup of your iPhone

Next, you need to backup your iPhone with one of the following options:

Option 1: Backup with iCloud

iCloud can be used to store your iPhone backup.

In your iPhone, go to Settings > [your account name] > iCloud > iCloud Backup.

Ensure that you've created a up-to-date backup by selecting "Back Up Now"

Allow the Backup to Finish.

Option 2: Backup Directly to Your Computer

Another option is store a local backup to your computer.

To back up your iPhone:

Connect the iPhone to your Mac. You should see a message on either your iPhone or Mac to trust the newly connected device, choose Trust. You will most likely see this message on both your Mac and iPhone.

On your Mac, open finder and select your iPhone under Locations in the sidebar.

On your Mac with Finder open, click on your iPhone and click the General tab.

Enable Back up all of the data on your iPhone to this Mac.

Click on Back Up Now.

It may help to make a note of the timestamp. It can make it easier to find the correct backup when it's time to restore.

Step 3: Choose how you'll Restore your Data After Resetting your iPhone

This section will help you decide how you will go about restoring your iPhone's data after you reset and enable supervised mode.

Option 1: Signing into Apple Account after Setup (simplest)

The simplest option is to just sign back into your Apple account and restore the items you chose to sync with iCloud (see Step 1). While this approach is the simplest, you won't be able to restore Apps and App Data.

You'll need to re-download apps from the App Store and login again into any accounts they used.

Make sure that both of these options are true:

Double-check your iCloud sync settings mentioned in Step 1. Ensure you are backing up your photos, messages, and contacts (at a bare minimum).

Double-check that you've created a full backup in Step 2. This gives you a fallback in case you need to revert, but you won't be restoring this full backup. This is just a precautionary step.

If you do need to fully restore all App Data, you can't do this by signing into your Apple Account and using iCloud sync. Consider option 2 if app data is important.

Option 2: Restore a Full Backup (advanced)

If you'd like to restore a full backup with all app data, it is possible but the process is not straightforward: you will need a spare iPhone that is capable of running the same iOS version as your current iPhone (in many cases, an older iPhone will do).

Confirm that your spare iPhone will work with this setup process:

Use Apple's iPhone model guide to look up your spare iPhone to see if it can run the iOS version used by your new iPhone.

Because of the way iPhone backups work, supervision data is reset when restoring a full backup. However, a workaround for this is if you transfer data from another iPhone, supervision status is retained.

If you choose to restore data with a transfer, you should create a backup on either your Mac or through iCloud.

Make sure that both of these options are true:

Double-check that your iCloud sync settings to ensure you are backing up important items. We recommend doing this as an extra precaution.

Double-check that you've saved an iPhone backup with either iCloud or locally on your Mac (see step 2).
