Usually, when you plug an iPhone into your PC, the “Trust This Computer” prompt appears on the mobile. Then, once you tap the “Trust” option, the device appears in the iTunes application.
However, when your device has issues connecting to the Windows system, you get the “iTunes could not connect to this iPhone. An unknown error occurred” with the bug check code

Besides that, the source of error could be the cables, the iTunes app, or the Windows system you are connected to.

Since your mobile device needs to grant permission to access it from the computer, make sure you unlock your phone while connecting. Also, tap the Trust option when prompted on the phone.
Likewise, disconnect your iPhone and exit the iTunes app before applying the following fixes.
Check if iPhone is Connected Properly
The above error mostly occurs when your iOS device (iPhone, iPod or iPad) has a problem connecting to the iTunes application on your Windows system.
Therefore, connect the lightning cable to a different system and check if it is working fine. On the other hand, try switching the USB port when connecting the iPhone. And if you are using a USB hub, connect the device directly to the device’s USB port.
Also, disconnect any other additional devices connected to your PC and make sure your PC is connected to only the iPhone.
Rename the Lockdown Folder
For each iOS device you connect to a particular computer, a lockdown folder is created automatically for each one on the PC. These folders contain lockdown certificates that store unique UDID data to know which data to sync for a particular iOS device.
So, if you connect multiple iOS devices to your PC, several of those folders exist in your system. And sometimes, they get corrupt, due to which you have issues connecting the device and may receive the

Restart Apple Mobile Device Service
The Apple Mobile Device Service is a Windows service that runs in the background. It helps to detect and connect any iOS device on a Windows system. If it’s not enabled or not working well, you can face issues while connecting your iOS device to Windows.
Therefore, you need to re-enable it and restart the service again to fix your issue. Here’s how you can do it.
- Press Windows + R, type
services.mscand press Enter.
- Look for the “Apple Mobile Device Service” service and double-click to open it.
- Under the General tab, set the Startup type to Automatic.
- Now, click Stop and then click Start to restart the service.
- Click Apply and OK to save changes.
- Reconnect your iPhone and launch iTunes. Check if the problem has been resolved.
Allow iTunes to Run on Your Firewall
When you connect your iPhone to a Windows system, it needs to run several processes in the background to perform various tasks.
For example, the
iPodService.exe process provides access to iTunes while connecting your iPhone and
AppleMobileSync.exe helps sync your device with the PC. Similarly, several other processes need to be executed, and sometimes your security software blocks them after misinterpreting them as malicious threats.
On Windows, the Windows Defender firewall, by default, scans for potential threats on your system unless you have installed another third-party antivirus/firewall. So, to resolve your issue, you have to disable the firewall. However, it isn’t safe, as you could be vulnerable to viruses and malware. A better option is to allow iTunes in the firewall.
- Open the Run command (Windows + R).
- Then, type
firewall.cpland press Enter to launch Windows Defender Firewall.
- Click Allow an app or feature through Windows Defender Firewall from the sidebar.
- Now, click Change settings to access the settings.
- Scroll down until you see iTunes.MSI and enable the Private and Public checkboxes next to it.
- Click OK to save changes.
Update the iTunes Application

- Launch the iTunes app.
- Click the Help menu and select Check for Updates.
- Wait for the app to search for and download the new updates.
- Follow the on-screen prompts and install the updates.

- Click the Edit menu and select the Preferences option.
- Then, under the Advanced tab, enable the “Check for new updates automatically” checkbox.
Update Your System and Device
