Fix iOS 11 Bricked iPhone 5s: Step-by-Step Guide

If your iPhone 5s is stuck on the Apple logo, won’t turn on, or shows a black screen after updating to iOS 11, you can usually fix it yourself by putting the device into Recovery Mode and restoring it with Finder or iTunes. This article walks you through the exact steps to unbrick your iPhone 5s, explains why this happens, and covers common pitfalls to avoid.

Why iOS 11 Bricked Some iPhone 5s Units

The iPhone 5s, released in 2013, was already three years old when iOS 11 launched in September 2017. The update brought a major visual redesign and new features like the Files app and a customizable Control Center, but it also introduced significant performance issues on older hardware. Many users reported that after the update, their devices became unresponsive, stuck in a boot loop, or appeared completely dead. In some cases, the installation itself failed, leaving the phone in a partially updated state that could not boot normally.

Apple did release subsequent iOS 11 point updates (like 11.0.1 and 11.0.2) that addressed some bugs, but if your device is already bricked, you need to restore it via a computer. The process is straightforward, but you need the right cable, a compatible computer, and a stable internet connection.

What You Need Before You Start

Before attempting any fix, gather these items:

• A computer with the latest version of iTunes (Windows) or Finder (macOS Catalina or later).
• The original Lightning cable or a certified third-party one. A damaged or non-certified cable can cause connection drops mid-restore.
• Your Apple ID password, because after restoring you will need to enter it to re-activate the phone (if Find My iPhone was enabled).
• At least 2 GB of free space on your computer for the iOS download.

If you have a backup, the restore will erase everything, so you’ll be able to recover your data from the backup afterward. If you never backed up, the data is likely unrecoverable once you restore.

Step-by-Step: How to Unbrick Your iPhone 5s

Follow these steps in order. If one step doesn’t work, move to the next.

Step 1: Force Restart (for minor glitches)

1. Press and hold the Home button and the Sleep/Wake (top) button simultaneously.
2. Keep holding both for at least 10 seconds until the Apple logo appears.
3. Release both buttons. If the phone boots to the lock screen, you’re done.

This works for temporary freezes, but if the phone is stuck in a boot loop (shows the Apple logo, restarts, shows it again), proceed to Recovery Mode.

Step 2: Enter Recovery Mode

1. Connect your iPhone 5s to your computer with the Lightning cable.
2. On the iPhone, press and hold the Home button and the Sleep/Wake button together.
3. Keep holding them even after the Apple logo appears. Do not release when you see the logo.
4. After about 10-15 seconds, you’ll see the Recovery Mode screen: a black background with a Lightning cable pointing to a computer icon.
5. Release both buttons. Your computer should now detect the device in Recovery Mode.

If you don’t see the Recovery Mode screen, try again, but this time hold the buttons for 20 seconds before releasing. If it still doesn’t work, move to DFU Mode below.

Step 3: Restore with Finder or iTunes

1. On your computer, open Finder (macOS Catalina or later) or iTunes (Windows or older macOS).
2. Select your iPhone when it appears in the sidebar (Finder) or the top-left corner (iTunes).
3. You’ll see a popup saying “There is a problem with the iPhone that requires it to be updated or restored.” Click Restore.
4. If no popup appears, click the Restore iPhone button in the Summary tab.
5. Confirm that you want to erase the device. The computer will download the iOS 11 IPSW file (about 2 GB) and install it.
6. Wait for the progress bar to complete. Do not unplug the phone during this time.
7. Once done, the iPhone will restart and show “Hello.” You can set it up as new or restore from a backup.

Step 4: If Restore Fails, Try DFU Mode

DFU (Device Firmware Update) Mode is a deeper recovery state that allows the computer to communicate with the phone even when the bootloader is broken. Here’s how to enter DFU on an iPhone 5s:

1. Connect the iPhone to the computer.
2. Turn off the phone (if it’s on). If it’s unresponsive, skip this.
3. Press and hold the Sleep/Wake button for 3 seconds.
4. Without releasing Sleep/Wake, also press and hold the Home button for 10 seconds.
5. After 10 seconds, release the Sleep/Wake button but keep holding Home for another 5 seconds.
6. If the screen stays black, you’re in DFU mode. If you see the Apple logo or the Recovery Mode screen, you missed the timing—try again.
7. Your computer should say “iPhone in recovery mode” or similar. Then restore as in Step 3.

Common Problems and Their Fixes

Even with the steps above, you might hit a snag. Here are the most frequent issues and how to resolve them:

• Error 4013 or 4014: This usually indicates a USB connection issue. Try a different port (preferably a USB 2.0 port on the back of a desktop), a different cable, or a different computer.
• Error 9: Often caused by a faulty cable or port. Try another cable and clean the Lightning port gently with a soft toothpick (no metal).
• Stuck on “Verifying update” for hours: This can happen if your computer’s date/time is wrong. Check that the date, time, and time zone are correct, then restart the process.
• iPhone not recognized by computer: Install the latest iTunes version, or if on macOS Catalina+, ensure Finder has permission to access the device (you’ll see a prompt).
• Restore completes but phone still stuck: Try a different computer or a different USB port. Also, try using a different iOS version (if you have the IPSW file) by holding Shift (Windows) or Option (macOS) while clicking Restore and selecting the file.

Why You Should Not Use Third-Party Tools

You’ll find many websites promoting “iOS system recovery” tools that claim to fix bricked iPhones without data loss. While some are legitimate, many are not, and using them can void your warranty, introduce malware, or permanently damage your device. The official Recovery Mode restore is the only method that Apple supports, and it’s free. If you want to try a third-party tool, research it thoroughly, but know that the official method is the most reliable.

How to Prevent This in the Future

To avoid another bricking incident:

• Always back up your iPhone before installing a major iOS update. Use iCloud or a computer backup.
• Ensure your iPhone has at least 50% battery or is plugged in during the update.
• Use a stable Wi-Fi connection to download the update.
• If you’re concerned about performance on an older device, consider staying on an older iOS version. Apple occasionally signs older versions, but not for long after a new release.

Frequently Asked Questions

Will I lose my data if I restore my iPhone 5s?

Yes, restoring erases everything on the phone. If you have a backup (iCloud or iTunes), you can restore your data after the process. If you never backed up, your data is lost.

Can I fix a bricked iPhone 5s without a computer?

No. The only way to restore a bricked iPhone is by connecting it to a computer with iTunes or Finder. You cannot do it wirelessly.

How long does the restore take?

The download of iOS 11 is about 2 GB, so it depends on your internet speed. The installation itself takes about 10-15 minutes. In total, expect 30-60 minutes.

What if my iPhone 5s is stuck in a boot loop after the restore?

If the restore completed successfully, the boot loop should be gone. If it persists, try putting the phone into DFU mode and restoring again. If that fails, the hardware may be faulty, and you should contact Apple Support or a repair shop.

Is my iPhone 5s too old for iOS 11?

Officially, the iPhone 5s supports iOS 11, but performance is sluggish. Many users recommend staying on iOS 10 for better speed. However, if you’ve already updated and it’s bricked, you’ll need to restore to iOS 11 (the only version Apple still signs for that device).

Can I downgrade to iOS 10 after restoring?

No. Apple stops signing older iOS versions shortly after releasing a new one. Once iOS 11 is installed, you cannot downgrade to iOS 10 unless you have saved SHSH blobs (which most users don’t).
