You are not getting the device into Recovery Mode. If you look at the support document that was provided, if you have never connected the device to iTunes, you need to force the device into Recovery Mode using the instructions provided. See this section.

If you've never synced with iTunes or set up Find My iPhone in iCloud, you'll need to use recovery mode to restore your device. This will erase the device and its passcode.

1. Connect your iOS device to your computer and open iTunes. If you don't have a computer, borrow one from a friend, or go to an Apple Retail Store or Apple Authorized Service Provider.
2. While your device is connected, force restart it: Press and hold the Sleep/Wake and Home buttons at the same time. Don't let go when you see the Apple logo — keep holding until you see the recovery mode screen.
   
3. When you see the option to Restore or Update, choose Restore.
   
   iTunes will download software for your device. If it takes more than 15 minutes, your device will exit recovery mode and you'll need to repeat steps 2 and 3.
   
   
4. Wait for the process to finish. Then you can set up and use your device.

If you have synced your device with a computer in the past, then use this section.
