220-1202 Practice Question: A user's iPhone is running iOS 16 and they cannot…
A user's iPhone is running iOS 16 and they cannot update to the latest iOS 17 because the 'Software Update' section in Settings shows 'Unable to Check for Update'. The device is connected to Wi-Fi and has sufficient storage. Which advanced troubleshooting step should you take to resolve this update issue?
⚠ Common exam trap
CompTIA often tests the misconception that 'Reset All Settings' or disabling network features like Private Relay will fix OTA update failures, when in fact the correct advanced step is to use a computer-based restore to bypass the device's broken OTA mechanism.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a computer with Finder (macOS) or iTunes (Windows) to download and install the update.
When an iPhone displays 'Unable to Check for Update' despite having Wi-Fi and storage, the issue often lies with the device's inability to contact Apple's update servers directly due to network restrictions or corrupted cached update data. Using a computer with Finder (macOS) or iTunes (Windows) bypasses the iPhone's over-the-air (OTA) update mechanism by downloading the full IPSW firmware directly from Apple's servers and installing it via USB, which is a standard advanced troubleshooting step for OTA update failures.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Reset All Settings from General > Reset.
Why it's wrong here
Resetting all settings restores preferences and network configurations but leaves the update-checking subsystem untouched, so the 'Unable to Check for Update' error remains. It is tempting because it clears corrupt configuration broadly, and would be correct for persistent Wi-Fi, Bluetooth or keyboard misbehaviour rather than a failed iOS update query.
- ✗
Restore the iPhone using an iCloud backup.
Why it's wrong here
Restoring an iCloud backup reinstates user data and settings; it neither replaces iOS system files nor clears the update-check fault. It would be appropriate after data loss or a corrupted profile, whereas an update failure typically needs a computer-based restore or recovery-mode update.
- ✓
Use a computer with Finder (macOS) or iTunes (Windows) to download and install the update.
Why this is correct
When over-the-air updates fail despite adequate Wi-Fi and storage, installing via Finder or iTunes forces a full firmware download over USB, bypassing the corrupted update cache or failed OTA check. This resolves the 'Unable to Check for Update' error.
- ✗
Disable iCloud Private Relay in iCloud settings.
Why it's wrong here
Private Relay only masks Safari traffic through two hops; it does not block the Apple update servers that Settings contacts, so 'Unable to Check for Update' persists. It is tempting because relay interference genuinely breaks some Apple services, but it would be the right fix for browsing or App Store connectivity faults, not update checks.
