Quick answer: iPhone Error 14 usually means the update or restore was interrupted. Free up 5–8GB of storage first, as this is the most common cause. Then use an original or MFi cable plugged straight into the computer, turn off Low Power Mode, update iTunes or macOS, and force restart. As a last step, use Recovery Mode → Update, which keeps your data. If it still fails, the battery, charging port or logic board may be at fault. Updated November 2026.
Your iPhone shows “Error 14” during an iOS update. iTunes can’t restore your device. The update stops at the Apple logo or enters recovery mode. This error prevents you from updating your iPhone completely.
Below are the causes we see most often at BreakFixNow Singapore, with the DIY fixes to try first and the repairs needed when they don’t work.
What Is iPhone Error 14?

- Try different USB ports
- Clean the iPhone charging port gently with compressed air

- If the toggle is green, tap to disable Low Power Mode
- Try the update again
Fix 4: Update iTunes/Finder
Mac: Apple menu → System Settings → Software Update
Windows: iTunes → Help → Check for Updates (or update the Apple Devices app from the Microsoft Store)
Fix 5: Force Restart
iPhone 8 and newer:
- Press and release Volume Up
- Press and release Volume Down
- Hold Side button until Apple logo appears
iPhone 7: Hold Volume Down + Side button (10 seconds)
iPhone 6s and earlier: Hold Home + Power button (10 seconds)
Fix 6: Use Recovery Mode

Frequently Asked Questions
What causes iPhone Error 14?
Error 14 is most often caused by insufficient storage (you need 5–8GB free), followed by USB cable or port issues, outdated iTunes or Low Power Mode, and less often hardware such as a degraded battery.
Can I fix Error 14 myself?
Yes, in most cases. Free up 5–8GB storage, use an original Apple cable, disable Low Power Mode, update iTunes, and force restart the iPhone. If none work, it’s likely hardware damage requiring professional repair.
How much storage do I need?
You need 5–8GB free. Go to Settings → General → iPhone Storage. Delete unused apps, photos and videos, and clear Safari data. Aim for 10GB+ for smooth updates.
Will fixing Error 14 delete data?
