Having trouble restoring iPhone 4s from 5.1.1 to 5.1.1 and I do have my shsh blobs?

I have a jailbroken iPhone 4s running 5.1.1. I want to restore my phone to the original stock firmware 5.1.1 (my current one). According to the jailbreak world i should be able to do that if i have my 5.1.1 ssh blobs, which i do have. I have tried every way i know, running TinyUmbrella's TSS server going through itunes and using the latest redsn0w 9.14b2. What am i missing i keep getting error (11) from itunes an di did edit the host files. I'm at a lose

I'm in the same boat. But to answer your question you can't. Not yet. It requires a BootRom Exploit and the 4S does not have one. So your stuck on 5.1.1 until they come up with a way around it.
