Part 1. What to Do If iDevice is Connected But Can't be Recognized?

If you are not sure which cause it could be to make your iOS device unrecognizable by the program, you can check the following possible reasons and the corresponding solutions one by one to ensure your iDevice can be recognized successfully.

1.1 Possible Reasons to Cause A Unrecognized iDevice

If your iOS device is unrecognized by the program, it could be the following reasons:

(1) The USB cable or USB port doesn't work properly, so the iDevice can't connect to the computer.

(2) You haven't tapped the "Trust" option on iDevice to authorize this computer when "Trust This Computer" prompt pops up.

(3) The iOS version is lower than iOS 4.0, and the program doesn't support it.

(4) There is poor connection between the device and computer, so the connection is not stable.

(5) The Apple Mobile Device service is not started on your computer.

(6) Sometimes the anti-virus software may limit the functionality of the program.

(7) Your iDevice can't be recognized by iTunes or Apple Music.

1.2 Corresponding Solutions to Have Your iDevice Recognizable

(1) If the USB cable or USB port doesn't work properly, please try another USB cable or USB port instead.

(2) When the program reminds you to tap "Trust" option on your iDevice, please unlock your iOS device with a password or fingerprint, then tap "Trust" option on your iDevice to connect it.

(3) If your iOS version is lower than iOS 4.0, you can download the previous version of the program to have a try (old iPods are supported):

Windows version: https://www.coolmuster.com/downloads/cool-iii2pc-transfer.exe

Mac version: https://www.coolmuster.com/downloads/cool-iii2mac-transfer.dmg

After trying that, if you found there is some problem with the licence code, please contact us via email to replace it: support@coolmuster.com.

(NOTE: Before upgrading iOS version, please backup your iDevice with iTunes or iCloud in case of unexpected data lost.)

(4) If there is bad connection between your device and computer, please disconnect all other USB connections except the mouse's and keyboard's, or restart your iOS device and computer.

(5) If the Apple Mobile Device service is not started, you need to launch it on your computer. To do so, on your Windows PC, please go to "Control Panel" > "Administrative Tools" as below:

(6) Sometimes the anti-virus software may limit the functionality of the program. To fix it, please change your antivirus settings or disable them when using the program.

Here please be noted that it is to temporarily disable anti-virus software, but not uninstall anti-virus software or other software on computer.

To disable anti-virus software on computer, please click "Start" > "Control Panel" > "System and Security" > "Action Center" > "Virus Protection" where you can see the installed anti-virus software on your computer. Then just disable it if it is on.

(7) If you have installed the iTunes on your computer, please check if it is the latest version. If not, please download and install the latest iTunes (iTunes 64-bit version of Windows or iTunes 32-bit version of Windows) from Apple's official website on your computer; or update iTunes to the latest version by clicking "Help" > "Check for Updates" on iTunes interface.

Part 2. The Latest iTunes Installed But Still Failed to Recognize iDevice?

Before going further, please be clear that your iOS device should be detectable by iTunes or Apple Music, otherwise the program might fail to detect your device.

If the latest iTunes is installed but it still failed to recognize your iDevice, this may be because of the recognition failure. Please get more solutions from Apple Support: https://support.apple.com/HT204095.
