Check for hardware issues

Errors: 1, 3, 11, 12, 13, 14, 16, 20, 21, 23, 26, 27, 28, 29, 34, 35, 36, 37, 40, 53, 56, 1002, 1004, 1011, 1012, 1014, 1667, or 1669.

Your device or computer might have a hardware issue that stops the update or restore from completing.

1. Check that your security software and settings aren't blocking your device from communicating with the Apple update server.
2. Then try to restore your iOS device two more times while connected with a cable, computer, and network you know are good.
3. Make sure that your security software and settings are allowing communication between your device and update servers.
4. If you still see the error message when you update or restore, contact Apple support.

If you still see the error message, check for outdated or modified software

That is exactly what has happened to me, we thought it might have been the battery so we got it changed at it was perfect but i tried to update to IOS 9; then it went through the normal routine but in the middle before it normally turns on again it went to  sign of the iTunes symbol with the charger, saying i needed to reboot. after ages of trying over and over we had the same result. SOMEONE HELP!

Hi, I tried this on my iPhone and it worked.

If it is not on recovery mode than you should do put on it - HERE IS HOW (https://support.apple.com/en-gb/HT201263)

Open your iPhone and than click on restore on iTunes. When iTunes says Extracting Software, press/hold the battery connector until the update/restore has been finished. This method did worked for me, so it might work for you.
