TS3694 unknown error 3004

Hi I'm trying to restore my iphone and I'm having problems. I put it in DFU mode just to try to get it cleanly updated but when I shift and select the ios 7 ipsw for the iphone 5 gsm, it says unknown error 3004. Now I can't get that far because iTunes says unable to contact update server. I'm not running a firewall or any third party except for Vipre anti virus (the version without the firewall), and whatever the default Windows 7 64-bit firewall configuration is.

Hi cypherx,
Do not worry about firewalls or anything like that. When you install iTunes it automatically opens the firewall to the correct ports. If it did not you would not be able to update iTunes.
The fix is very simple. It is in your hosts file. It sounds like you have a bad IP address for gs.apple.com.
1. From the start menu click on computer > C: > windows > system32 > drivers > etc
2. Copy your hosts file to your desktop.
3. Open your hosts file with notepad.
4. Look for gs.apple.com. If there are IP address numbers before gs.apple.com
Example::
74.208.105.171     gs.apple.com
79.208.10.249     gs.apple.com
17.171.36.30     gs.apple.com
Put a hashtag before each IP address as below.
#74.208.105.171     gs.apple.com
#79.208.10.249     gs.apple.com
#17.171.36.30     gs.apple.com
After doing this press "ctrl-S" to save the file then move it back to the following folder or cut and paste it.
computer > C: > windows > system32 > drivers > etc
Your iPhone, iPad, iPod will restore at this point. We effectively removed bad redirects from your hosts file.

TS3694 Unknown error occured (6)

During update I received "Unknown error occurred (6). How do I get my phone to work again?

The answer is in the knowledge base article you were reading when you posted your question: http://support.apple.com/kb/TS3694#error6
Errors related to third-party security software
Error 2, 4 (or -4), 6, 1000, and 9006
Follow the steps to troubleshoot security software. Often, uninstalling third-party security software will resolve these errors.
There may be third-party software that modifies your default packet size in Windows by inserting a TcpWindowSize entry into your registry. An incorrectly set default packet size can cause these errors. Contact the manufacturer of the software that installed the packet size modification for assistance or follow this article by Microsoft: How to reset Internet Protocol (TCP/IP).
Verify that access to ports 80 and 443 are allowed on your network.
Verify that communication to albert.apple.com or phobos.apple.com isn't blocked by a firewall or other Internet security setting.
Discard the .ipsw file, open iTunes and attempt to download the update again. See the steps under "Advanced steps > Rename, move, or delete the iOS software file (.ipsw)" below for file locations.
Restore your device while connected to a different network.
Restore using a different computer.

An error message pops up saying "Unknown error 6" while I was updating my iPhone4 to iOS6 last night?

Check this support document for error codes http://support.apple.com/kb/TS3694, however, it says that error code 6 is generally related to 3rd party security software. Read the fixes described in the document.

TS3694 unknown error 2001

The battery in my iPhone 4 drained really fast today. When I plugged it in I just got the itunes logo on the screen.
When I try to restore the phone now i get unknown error 2001
Anyone else had this problem?

Error 2000-2009 (2001, 2002, 2005, 2006, 2009, and so on)
If you experience this issue on a Mac, disconnect third-party devices, hubs, spare cables, displays, reset the SMC, and then try to restore. If you are using a Windows computer, remove all USB devices and spare cables other than your keyboard, mouse, and the device, restart the computer, and try to restore. If that does not resolve the issue, try the USB issue-resolution steps and articles listed for Error 1604 above. If the issue persists, it may be related to conflicting security software.

TS3694 getting error 3004 when trying to update to ios7

I keep getting error 3004 when trying to update to ios7

I was trying to update my iphone 5 to IOS7 and couldnt do it for 5 times then I did the following and was able to update it right away
Clearing your DNS cache may resolve the issue and enable you to connect to the iTunes Store.
The easiest way to clear your DNS cache is to shut down your computer completely and then restart. If you can't shut down, you can clear your DNS cache manually.
Click Start and choose Run.
In the dialog that appears, type “cmd” (don’t type the quotes) and click OK.
After the DOS prompt (C:\), type “ipconfig /flushdns” (without the quotes) and press Enter. Make sure you enter a single blank space after “ipconfig.”
Let me know if it solved the issue for you

TS3694 unknown error occured 3194

I just can not restore my iPhne 3GS. There is no os in it . When it is started, it displays the message" recovery mode, restore immediately" I have tried many time to restore but unknown error 3194. Please help to restore my iPhone. Thank you very much.

The article steps for this are:
1. Insure you have the latest version of iTunes (11.0.2.26)
2. Check security software (Either disable, or temporarily uninstall the software).
3. Check the hosts file:
The restore will fail if there is an active entry to redirect gs.apple.com. FollowiTunes: Advanced iTunes Store troubleshooting to edit the hosts file or revert to a default hosts file. See section "Blocked by configuration: (Mac OS X/Windows) > Rebuild network information".
4. Try to restore from another known good computer and network (Make an appointment at the genius bar)
5. If the error persists on another computer - Device may need service.
My bet would be Security software. If you uninstall - you can choose to keep your settings for a reinstall. Reboot the computer after removing the software.
HTH, and best of luck.
