When i try to update my phone it says error 4013

Hi there, this is most likely a software issue, try these steps

1. Make sure that your Mac has the latest version of macOS or the latest version of iTunes.
2. Force your device to restart:

• • iPad models without a Home button: Press and quickly release the volume button closest to the top button. Press and quickly release the volume button farthest from the top button. Press and hold the top button until the device restarts. If you're not sure, see which buttons you need to press to restart your iPad.
  • iPhone 8 or later: Press and quickly release the volume up button. Press and quickly release the volume down button. Press and hold the side button until you see the Apple logo.
  • iPhone 7, iPhone 7 Plus, and iPod touch (7th generation): Press and hold both the side (or top) button and the volume down button until you see the Apple logo. 
  • iPad models with a Home button, iPhone 6s or earlier, and iPod touch (6th generation) or earlier: Press and hold both the side (or top) button and the Home button until you see the Apple logo.

1. Connect your device to your computer using a USB cable. Locate your device on your computer.
2. When you see the option to update or restore, click Update — not Restore — to reinstall the software and keep your personal data.

IF this is not working, try these steps

1. Check for updates to your Mac or PC. If you restart your computer for an update, check for updates again after you restart.
2. Try to restore your device using another USB cable.
3. Try to restore your device on another computer.

If you continue to see error 9, 4005, 4013, or 4014 when you try to restore your iPhone, iPad, or iPod touch, contact us.
