Errors 3000-3999 (3004, 3013, 3014, 3018, 3164, 3194, and so on): Error codes in the 3000 range generally mean that iTunes cannot contact the update server (gs.apple.com) on ports 80 or 443.

1. Update to the latest version of iTunes.
2. Verify the computer's date and time are accurate.
3. Check that your security or firewall software is not interfering with ports 80 or 443, or with the server gs.apple.com.
4. Follow Troubleshooting security software. Often, uninstalling third-party security software will resolve these errors.
5. An entry in your hosts file may be redirecting requests to gs.apple.com (see "Unable to contact the iOS software update server gs.apple.com" above).
6. Internet proxy settings can cause this issue. If you are using a proxy, try without using one.
7. Test restoring while connected to a known-good network.

Here is my solution...I tried for a couple of hours and I stumbled upon this...

- Unplug your ipad and make sure its in recovery mode

- Make sure you have newest iTunes installed

- Goto C:\Windows\System32\drivers\etc

- Make new folder here (name it ipsw) You will also need administrative priviliges

- Move the ipsw files to new folder that you created in the C:\Windows\System32\drivers\etc directory

- Plug your ipad back in recovery mode

- Select your ipsw from the NEW ipsw folder in the C:\Windows\System32\drivers\etc directory by holding the "SHIFT" key when you choose the "RESTORE IPAD"

Voila...

Thanks!

What worked for me:

• Make sure the Mac (or PC, presumably) you are running iTunes on is connected to a physical network connection. (i.e it has a network cable connected.)
• Turn off Wi-Fi on the Mac (or PC).

This forces iTunes to use the physical rather than the wireless network - you can turn Wi-Fi on again once you are done with the restore.

Regards,

krm.

im gonna tell you the only way i could fix this was to download the right ipsw for my iphone and when it finished downloading move to desktop you then should have an icon then MAKE SURE YOU RIGHT CLICK THEN CLICK RENAME AND AT THE END OF THE NAME TYPE( .ipsw) THEN GO HOOK UP IPHONE PUT INTO RECOVERY MODE THEN CLICK RESTORE WHILE HOLDING SHIFT AND SELECT THE IPSW YOU JUST RENAMED BAMMMMMM!!!!!! THEN WAIT BUT IT WILL NOT WORK IF YOU DIDNT DOWNLOAD THE RIGHT IPSW FILE

I have done updates in the past with no issue but this time I was getting the 3004 error. I rebooted the Mac to no avail. Then I decided that it did indeed smell like a network issue as Apple indicated was a possibility. The only network change I had made in the last several months was the addition of a Sprint Airvana Micro cell. It is a pretty flaky device to start with so I thought, lets start with it. I disconnected the Ethernet cable from the Airvana and bingo, all is well, both the iPad and the iPhone updated perfectly.

So, if you have one of these devices on your network, you may just want to disconnect it and see if that resolves the install issue.

After completing both installs, I just plugged the Ethernet back into the Airvana and after a couple hours it is working again.

I faced the same issue.

I am using enterprise wifi with proxy.

I resolved 3004 issue as below:

1. Settings> General> Reset > Reset Network Settings

2. Wi-Fi> connect> your username and password> Accept Certificate and done

Hey,

Ummmmm.... Could you explain it more clearly? I really want to fix this issue and I'm pretty hopeless right now, so I want to try that solution of yours but I don't understand it. I mean what are ipsw files?

AND DOING THIS IS PRETTY MUCH CALLED A TRICKY BACKROLL!!!!!!!!

The problem is sync issue. in those countries which are not authorized by apple you will encounter to this issue so the way to bypass it is to using VPN connection(PPTP).

I solved it by using the software.

It is really helpful. Just on click of a button it restart's your device 🙂 .
