If you tried all the other options to fix this issue, including connecting your device to another computer with a different USB cable, but nothing worked, consider taking your device to a repair shop so that they can investigate this issue further.

Maybe you get the error code 2009 because the iTunes version installed in your computer is outdated. In this case, all you need to do is to update it, either via iTunes itself or by downloading it from Apple's website.

To check if your iTunes version is up-to-date (and update it, if it's not), open iTunes, click on Help and select Check for Updates.

Another reason for error 2009 is a bad connection between the computer and the iOS device. Disconnect and reconnect the USB cable on both ends and try restoring your device again.

There is an extremely small possibility that an outdated antivirus software is the reason for the error 2009 message, because it mistakenly believes that iTunes files, or files iTunes attempts to download to update or restore your iOS device will do harm the computer. This is usually the case if you update iTunes to the latest version, but you haven't updated iTunes in a long time. To fix this, check if an update for your antivirus software is available, by visiting the developer's website and if it is, apply it.

You can check if an update is available for your operating system in the Help, or Setup tab of your antivirus software, or by visiting the antivirus developer's website. If an update is available, apply it.
