I can't restore my iphone 4s?

I have a jailbroken iphone 4s with ios 7.0.4. I have the ios 7.0.4 ipsw file on my computer. Whenever i try to manually restore it to 7.0.4 using itunes v11.4, its give me error 3194. I tried to restore it while in dfu mode and tss server on in tinyumbrella but it gets stuck in preparing iphone for restore. I actually wanted to upgrade to ios 7.1.2 but not ios 8.0.2 since there's no jailbreak for ios 8.x.x. How can i restore it ios 7.0.4 or upgrade it to ios 7.1.2 but not ios 8.0.2.

Try these steps may help you to get the solution
1. Open Settings from your home screen
2. Tap on "General". Your iTouch device will detect latest update.
3. When it will show iOS 7.1.x update, click on Download and Install button.
4. Now your device will update the firmware through the air and reboot to complete the procedure.
All the best!

Sorry you can no longer update to iOS 7.1.x as Apple stopped signing couple days ago. All you can do is perform a semi-restore
