I was lucky enough to find an iphone 4s with version 8.4. I want to upgrade to 9.0.2 but when I try to install 9.0.2 ipsw file through itunes I get error 3194. How can I do this.

I'd advise you stay in 8.4, iOS 9.3.1 has more stuttering and input-blocking than 8.4, your iPhone will feel sluggish.

If I was to jailbreak it on version 8.3 would that give me the capability to update it to 9.0.2 in order to jailbreak it at 9.0.2?
