I recently subscribed to Netflix as I am having reliability issues with Icefilms and Navi-X on my jailbroken ATV2. The Netflix shortcut was missing in version 4.3 so I decided to upgrade to 4.4.4, not realising version 5.0 (4099) was available, the system upgrdaed to the latest version. As I cannot jailbreak the latest firmware, I am desperate to downgrade to 4.4.4. I have the IPSW but when I try to restore using I tunes I get an error message saying it encountered an unkown error (3194). This was my own stupidity, can anyone advise how to downgrade without the errors?
without your shsh blobs you cant
I am in the same boat, although the difference is I never upgraded. Just got an apple tv g2 yesterday and it came with firmware 5.0 (4099) installed. Can this be jailbroken yet? because I have tried through seasonspass and cannot get past the “create ispw” screen. Says that this AppleTV is not eligible with this version.
Any solutions?
As far as I know the 5.0 firmware cannot yet be jailbroken.
There have been some suggestions that the jailbreak may not be far off for the ATV2, although it is likely to take longer for the new ATV3.

Im also in the same boat. Bought a second atv2 off someone saying it was at 4.4.4, took it home and fired it up, was upgraded to 5! 
I have tried Ireb, TinyUmberella, seas0npass with no luck. My own stupidity and I am furious. I guess we will have to wait on the next jailbreak!

Read this on another forum. It might help your case.
Fixing Error 3194
Fixing error 3194 is quite simple but you still need to pay attention to the steps. Since this problem is triggered when the Apple firmware signing services detects an unsigned custom firmware, a solution for it is to block the firmware signing service. Here’s how you do it:
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.
This method that I’ve shared with you is only temporary because in the end you have to restore the hosts file to its original state. That means, if you want to restore or downgrade your device iOS again in the near future with an unsigned firmware, you’ll have to repeat this process. However, there is a way to fix it easily without editing the hosts file yourself. For this, I’ll recommend to you a great registry cleaner.
I have bypassed 3194 but at the end I went to 1602 
After killing ipod service I went to 1601 and I am stuck here
Are you plug off the power cable???
