unknown error 2009

Google search "DFU mode IPSW restore" without the quotes. There will be tutorials on how to create a DFU (Device Firmware Update) mode IPSW (iDevice software) for your device that you can restore to in iTunes and then restore again to your firmware.

iMac 27" Late 2010, iPad Mini with Retina Display, OS X 10.9 Mavericks, OS X 10.6.3, Windows 7, iPod Touch 2nd Generation, iOS 7.0.4 and iOS 4.1

Apple says:

Check USB connections

If there’s an issue with the USB port, cable, dock, or hub, or if the device becomes disconnected during restore, try troubleshooting the USB connection, then troubleshooting your security software.

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.

Check for hardware issues

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.

Have you jailbroken your device? Jailbreaking sometimes adds a bricklayer between iTunes so the device will refuse to restore.

go to http://felixbruns.de/iPod/firmware and download your iPod/iPhone/iPad's model firmware.

Hold shift and click Restore in iTunes (or option+restore in Mac) and browse to the firmware you downloaded.

Note: Firmware takes a while to download.

Firmware name format should be like this:

iPod2,1_4.2.1_8C148_Restore.ipsw (for a 2nd Gen iPod touch restoring to iOS 4.2.1)

iPad3,1_6.0.1_10A523_Restore.ipsw (for a 3rd Gen iPad restoring to 6.0.1)

Also note: Apple only allows the latest version of iOS firmware to be restored.

This prevents jailbreaking older firmware. (If you dont know what jailbreaking is, then good)
