Apple introduced a security feature that disables USB accessories if the phone has been locked for more than an hour. This can interfere with pairing.
This is the solution that works for 80% of users. We are going to delete the corrupted pairing files, forcing Apple's services to create fresh ones.
For Windows 10/11:
Lockdown folder. (Don't worry—these are just pairing records. Nothing personal is lost.)C:\Users\[Your Username]\AppData\Local\Apple Computer\Lockdown and delete contents there if they exist.For macOS:
The "Pairing Failed" error is infuriating because it stops you from backing up or managing your device. But remember: your data is safe. This is a communication problem, not a data loss problem.
In 99% of cases, Step 3 (deleting the Lockdown folder) combined with Step 1 (unlocking the device and tapping Trust) will solve the issue immediately. Take a deep breath, work through the steps methodically, and you will have iMazing up and running again within 15 minutes.
Good luck
If you've encountered the "iMazing pairing failed" error, it typically means the secure handshake between your iOS device and computer has been interrupted. This guide provides a systematic approach to resolving these connection issues on both Mac and Windows. 1. Fundamental First Steps
Before diving into complex settings, try these quick fixes that resolve the majority of pairing issues:
Check the Cable: Use the original Apple cable or a certified MFi cable. Some third-party cables only support charging, not data transfer.
Connect Directly: Avoid using USB hubs or keyboard ports. Connect your iPhone or iPad directly to a port on your computer.
Trust the Computer: Unlock your device and look for the "Trust This Computer?" prompt. If it appeared earlier but pairing still failed, you can force it to reappear by going to Settings > General > Transfer or Reset iPhone > Reset > Reset Location & Privacy.
Restart Everything: Fully power down your mobile device and your computer, then relaunch iMazing before reconnecting. 2. Troubleshooting for Windows Users
Pairing failures on Windows are often caused by outdated or corrupted Apple drivers.
Reinstall Mobile Device Services: Open iMazing, go to Edit > Preferences > General, and click Reinstall Mobile Device Services. This refreshes the underlying Apple drivers without requiring a full iTunes installation. Address Bonjour Conflicts:
Windows 10/11: These versions support mDNS natively. If you have Apple’s Bonjour package installed separately, it can cause conflicts; try uninstalling it.
Windows 7/8: Ensure Bonjour is installed, as it is required for device discovery.
Security Software: Add iMazing.exe, AppleMobileDeviceService.exe, and AppleMobileDeviceProcess.exe to your antivirus or firewall whitelist. 3. Troubleshooting for Mac Users
Mac users may face pairing failures due to system-level permissions or specific macOS updates.
Update macOS: Ensure you are running the latest version of macOS via System Settings > Software Update.
Local Network Permissions (macOS Sequoia and later): Go to System Settings > Privacy & Security > Local Network and ensure that iMazing and iMazing Mini are toggled ON.
Firewall Adjustments: In System Settings > Privacy & Security > Firewall > Options, check that Automatically allow signed software to receive incoming connections is enabled. 4. Resolving Specific Error Messages
"kAMDPermissionError": This often indicates a device restriction profile. If the device is managed by an organization, it may be restricted from pairing with unauthorized computers.
"Couldn't Start Session": This usually suggests the pairing records on your computer are corrupted. In iMazing, right-click your device in the sidebar, select Forget, and then try to pair it again as if for the first time.
Supervised Devices: If your device is supervised, you may need to import the supervision certificate into iMazing's library to allow pairing.
If your device is still not appearing, try connecting it via USB for a few seconds to establish a physical link, which often clears the path for future wireless pairing. iMazing First Aid: Troubleshoot Connection Problems
How to Fix the "iMazing Pairing Failed" Error If you’re seeing a "Pairing Failed" message in iMazing,
it usually means there is a communication breakdown between your iPhone/iPad and your computer
. This common glitch can be caused by anything from a faulty cable to a security setting deep within macOS or Windows.
Here is a step-by-step guide to troubleshooting and fixing the issue so you can get back to managing your data. 1. Check Your Device’s "Trust" Status
The most frequent cause is that the "Trust This Computer" prompt was either dismissed or didn't trigger correctly. Unplug and Replug:
Disconnect your device, wait 5 seconds, and plug it back in. Unlock Your Screen:
Make sure your iPhone/iPad is unlocked. Look for the "Trust This Computer?" popup and tap Reset Trust Settings: If the popup doesn't appear, go to
Settings > General > Transfer or Reset [Device] > Reset > Reset Location & Privacy imazing pairing failed
. This clears all trusted computers and should force the prompt to reappear when you reconnect. 2. Verify the Connection Hardware Software can’t bridge a gap created by a broken wire. Use an Apple-Certified Cable:
Third-party cables often lack the necessary data pins for complex transfers. Try an original Apple Lightning or USB-C cable. Switch Ports:
Plug directly into your computer’s USB port rather than a USB hub or keyboard port. Clean the Port:
Use a toothpick or compressed air to gently remove lint from your device’s charging port. 3. Restart Everything
It sounds cliché, but a "Pairing Failed" error is often a frozen background process. Restart the iOS device (Power button + Volume Up). Restart your computer. Restart iMazing. 4. Check for Driver or Software Conflicts
On Windows, iMazing relies on Apple’s drivers to "see" your device. Update iMazing: Go to the top menu and check for updates. Reinstall Apple Mobile Device Support:
If you’re on Windows, you may need to repair or reinstall the Apple drivers. iMazing often provides a prompt to do this within its own Preferences under the Disable Security Software:
Occasionally, aggressive antivirus or firewalls block the pairing handshake. Temporarily disable them to see if the connection establishes. 5. Check "Pairing Records" in iMazing
iMazing stores "pairing records" to remember your device. If these are corrupted, pairing will fail. Open iMazing Preferences Find your device in the list and click Remove Pairing Records Reconnect the device to create a fresh, clean pairing. 6. The "DFU" or "Recovery" Check
If the device won't pair even after a reset, check if your computer recognizes it at all in (Windows) or
(macOS). If iTunes/Finder also fails to see the device, the issue is likely with your computer's USB drivers or the device hardware itself. Still having trouble?
Try connecting your device to a different computer to determine if the issue lies with your PC/Mac or the iPhone itself. operating system are you using (Windows or macOS), and does the prompt appear on your phone when you plug it in?
