Solution: iTunes Doesn't Detect iPhone — Step-by-Step Fix

Introduction / Why This Is Needed

Connecting an iPhone to a computer via iTunes is a basic operation for backing up, transferring a media library, or restoring firmware. If the program stops recognizing your device, you lose access to important data and smartphone management functions. Following this guide will restore a stable connection without reinstalling the system or visiting a service center.

Requirements / Preparation

Before you begin, ensure you have:

• An original Apple cable or an accessory with MFi certification.
• A computer running Windows 10/11 or macOS 10.15 or later.
• An unlocked iPhone with an active screen.
• Local administrator rights on the computer (for installing drivers and managing services).

💡 Tip: Disable third-party antivirus and firewall software during troubleshooting. They often block USB ports or network synchronization services.

Step 1: Check Cable and Physical Ports

Start with hardware diagnostics. Damaged cables and dirty connectors cause most connection problems.

1. Inspect the connector for bends, oxidation, or pulled contacts.
2. Gently clean the Lightning or USB-C port on the iPhone with a wooden toothpick. Do not use metal objects—they can short the contacts.
3. Connect the cable directly to a USB port on the motherboard (for desktop PCs) or to a port with a power icon on a laptop. Avoid using passive USB hubs.

Step 2: Trust Permission on iPhone Screen

iOS requires explicit confirmation to exchange data with new computers.

1. Connect the iPhone to the PC. If the screen is locked, unlock it using Face ID, Touch ID, or your passcode.
2. A system prompt will appear on the screen: "Trust This Computer?". Tap Trust and enter your unlock passcode.
3. If the prompt does not appear, go to Settings → General → Transfer or Reset iPhone → Reset Location & Privacy. After resetting, reconnect the cable.

Step 3: Update Software and Restart Services

If the hardware is fine, the issue lies in the software environment. Actions differ for Windows and macOS.

For Windows 10/11

The Apple Mobile Device driver often crashes or becomes outdated.

1. Open Device Manager (press Win + X and select it from the menu).
2. Expand the Portable Devices or Universal Serial Bus controllers branch.
3. Find Apple Mobile Device USB Driver, right-click, and select Uninstall device.
4. Restart the computer. iTunes will automatically reinstall the correct driver on the next launch.

To force-restart the synchronization service, open Command Prompt with administrator rights and run:

net stop "Apple Mobile Device"
net start "Apple Mobile Device"

For macOS

On macOS 10.15 and later, iTunes is split into separate apps. iPhone synchronization is now done through Finder.

1. Ensure your system is updated to the latest available version.
2. Open a Finder window, select your iPhone in the sidebar under Locations.
3. If the device is hidden, go to the Finder menu → Settings → Sidebar tab and check CD, DVDs, and iOS Devices.

Verify the Result

Open iTunes (or Finder on Mac). An icon for your iPhone should appear in the top bar or sidebar. Clicking it opens a management panel with sections like "Summary," "Backups," and "Files." Try starting a manual sync—if the progress bar fills without errors, the connection is restored.

Potential Issues

• Device recognized as "Unknown USB". Replace the cable or try another computer. If the problem persists, there may be a hardware failure in the iPhone's power controller.
• iTunes shows error 0xE or 0xE2. This usually indicates a driver signature conflict. Completely uninstall iTunes via "Apps & Features," download the official installer from Apple's website, and run the installation as an administrator.
• Computer sees iPhone but cannot access files. Go to Settings → Music → Sync over Wi-Fi and enable the option. Sometimes disabling Low Power Mode on the iPhone also helps.
