iTunes Cannot Restore Backup to iPhone Error – An Overview
‘iTunes cannot restore to iPhone’ issue may occur for many reasons, including outdated iTunes, insufficient space available on the iPhone, or a corrupted backup. Users reported that when encountering this issue, they received an error message: “The ‘iPhone 15’ could not be restored. An unknown error occurred.” Many users have sought solutions on Apple and Reddit forums for this error. If you’re also facing this issue, try the following fixes.
Methods to fix iTunes Cannot Restore to iPhone Error
Method 1: Check Remaining iPhone Storage
Insufficient storage on your iPhone will restrict you from restoring your data. You need at least twice the overall space required by the backup on iPhone or iPad. That space should be free and available to restore the backup. To check whether you have enough space available to restore backup to your iPhone, follow the given steps:
- Go to the Settings and then tap on General.
- Scroll down and tap on iPhone Storage. You’ll see the used storage on the top.
- The available storage appears in the greyed out bar below the used storage. You can determine whether it’s enough to restore the iPhone backup.
Method 2: Erase Existing Data and Restore Backups
iCloud and iTunes support data restoration only for brand-new iPhones. If your iPhone is already in use, or you have a second-hand iPhone, you must erase all the existing data and try restoring the backup. To do so, follow the given steps:
- Go to Settings on your iPhone.
- Tap on the General tab, scroll to the bottom, and choose Transfer or Reset iPhone.
- Tap on Erase All Content and Settings.
- This step will reset and then reboot your iPhone automatically. Now, you can check if all the restored data is there.
Method 3: Restore from iCloud
Other than the older iPhone versions, some iPhone 15/14 users have also received the ‘iTunes cannot restore backup to iPhone’ error while trying to restore backup to the iPhone. In this case, you can follow the given steps to restore iCloud backup to your iPhone:
- Go to Settings and then go to your Apple ID.
- Then go to iCloud.
- Select the data you want to restore or click Show All.
- Choose the one item/folder you need from all the items backed up by iCloud.
- After this, toggle on the Sync this iPhone option.
- All your data will be synced and restored to your iPhone.
