Can I ask how you are doing the restore?
And just to be sure, your using 9A406A?
You would normally get a 3194 error because the apple servers will no longer sign the release.
1. First of all, exit iTunes.
2. After you have done that, you now have to locate your hosts file. You can find this file in C:\windows\system32\drivers\hosts.
3. Now, open the hosts file with Notepad. You need to have Administrator Privileges to edit this file so make sure you open Notepad with Administrator Privileges by right-clicking Notepad and select Run as Administrator.
4. At the bottom of the hosts file, one line below the last text, type in this; #74.208.105.171 gs.apple.com
5. Next, connect your device to your computer and launch iTunes.
6. Put your device into DFU Mode when it is connected to your computer. You do this by first turning off the device, then hold down the power and the sleep button for about 10 seconds. After 10 seconds, release the Power button but keep holding down the home button until iTunes says that your device is in the recover mode.
7. Now, you can use iTunes to restore the iOS on your Apple device as usual.
8. After you have updated your iOS, in the hosts file which you have edited earlier remove the #71.208.105.171 gs.apple.com line that you added. This is to allow iTunes to perform updates as usual.
You can also do this if you use Tiny Umbrella by changing the setting "Set hosts to cydia on exit"
