Hello SaeedMoha.

In the previous response, we had shared a helpful resource for getting your iPhone fully updated. Were you able to follow all the steps listed within? If you're receiving error messages while trying to update your iPhone, then we recommend that you follow the steps listed in this resource to get fully updated: If you see an error when you update or restore your iPhone, iPad, or iPod - Apple Support

1.) Update your Mac or PC: Update macOS on Mac - Apple Support

2.) Plug your device directly into your computer. Plug your iPhone, iPad, or iPod directly into your computer's USB port (not into an attached keyboard or USB hub). Make sure that the cable is in good condition.

Make sure that your device is unlocked. If prompted, trust your device.

If you still see an error alert, try a different Apple USB cable or switch to a different USB port on your computer.

3.) Restart your computer and your device: Restart your iPhone - Apple Support

4.) Check your computer’s security software. If you're using an anti-virus or VPN, try disabling them.

5.) Use a different computer.
