I am assuming your friend means iOS 8.1.2, but iOS 8.1.3 is now out and 8.1.2 is no longer being signed.

As for the error, "
Check your security software
Related errors: 2, 4, 6, 9, 1000, 1611, 9006. Sometimes security software can prevent your device from communicating with either the Apple update server or with your device.

Check your security software and settings to make sure that they aren't preventing a connection to the Apple servers."

And its iphone 4 so i guess 8.1.2 is not compatible... Right ?
My bad, I was unaware of this. The OS for iPhone 4 is 7.1.2 according to IPSW downloads.

Make sure the Hosts file is correct, reboot the computer, temporarily disable the antivirus software, put the iPhone in DFU mode and then restore.

Hello,
I have downloaded manually ipsw file but i don't know where do i paste this file in itunes folder... Could you please help ?
Did your friend try Europa's suggestions of rebooting computer, and put iPhone in DFU mode to restore?

Entering DFU Mode on iPhone, iPad or iPod touch
  1. Plug your device into your computer with a USB cable.
  2. Turn off the device.
  3. Hold the Power button for 3 seconds.
  4. Hold the Home and Power buttons for 10 seconds.
  5. Release the Power button but keep holding the Home button.
  6. After about 15 seconds you will be alerted by iTunes saying that it has detected a device in Recovery Mode.

Checking the host file and rebooting his computer by disabling antivirus did not work. Have manually downloaded 7.1.2 firmware from the internet and then restored using itunes.

This means all is well and you're on iOS 7.1.2?

To answer previous question, you drag the downloaded firmware to iTunes with the iPhone plugged in where iTunes recognizes it.
