In tools that communicate with an iPhone or iPad, a lockdown-session pairing error usually points to a missing or invalid trust relationship. The exact wording is tool-specific; it does not refer to an exam browser or necessarily to Apple’s Lockdown Mode security feature.
Step-by-step solution
- Unlock your own device, connect it directly using a data-capable USB cable, and keep it unlocked during the first connection.
- Open Finder on a Mac or Apple Devices on Windows. Select the device and approve Trust on the computer and on the phone when prompted.
- If the trust prompt does not appear, disconnect and reconnect, restart both devices, and install supported updates for the Apple software.
- If trust remains broken, use the iPhone’s Settings → General → Transfer or Reset iPhone → Reset → Reset Location & Privacy. This resets privacy permissions and trusted-computer choices; it is not Erase All Content and Settings.
- Reconnect, approve trust again, and confirm the device appears in Apple’s software before retrying the third-party tool. Check that tool’s compatibility with your iOS version.
How to check the fix
Apple Devices or Finder recognizes the unlocked device and can open its information page. If only the third-party tool fails, report the problem to its maintainer.
Before you try other fixes
Do not download someone else’s pairing file or publish your own. Pairing records are device-specific and security-sensitive.
