Resolve specific iTunes update and restore errors
When you're backing up or restoring your iPhone, iPad, or iPod touch, you might see an error message. Here’s how to resolve it.
Try these steps first
Use the basic troubleshooting steps to resolve most backup and restore issues.
Find your error number here and follow the steps.
Check the hosts file or TCP/IP filtering, which might cause communication issues between iTunes, ports, and servers.
Common errors: 1004, 1013, 1638, 3014, 3194, or 3000-3999. These alerts refer to gs.apple.com, say "There was a problem downloading the software", or say the "device isn't eligible for the requested build".
Check your security software and settings, which can block ports and prevent connection to Apple servers during update and restore.
Common errors: 2, 4, 6, 9, 1000, 1611, 9006, 9807, 9844. Sometimes as a result of this issue, a device might stop responding during the restore process.
Common errors: 13, 14, 1600-1629, 1643-1650, 2000-2009, 4000, 4005, 4013, 4014, 4016, “invalid response”, and being prompted to restore again after a restore completes.
To narrow down the issue, you can also change up your hardware:
- Use another USB cable.
- Plug your cable into a different USB port on your computer.
- Try a different dock connector (or no dock).
- Add (or remove) a USB hub between your device and computer.
- Connect your computer directly to your Internet source, with no routers, hubs, or switches.
If you see your error after changing your USB connections, continue to the next section to troubleshoot your hardware.
Try to restore your iOS device two more times while connected with a cable, computer, and network you know are good. Also, confirm your security software and settings are allowing communication between your device and update servers. If you still see the alert when you update or restore, contact Apple support.
Common errors: 1, 10-47, 1002, 1011, 1012, 1014, 1000-1020.
Confirm your iOS version
If you see the message “The required resource can't be found,” your device may have a newer version of iOS than is available in iTunes. Confirm the iOS version on your device by tapping Settings > General > About. If the version is newer than the latest released iOS version, your device may have a prerelease developer version of iOS.
Quit virtualization software
Quit any virtualization software (such as Parallels or VMware) that’s running on your Mac. Then use the latest version of iTunes to restore your device.
