I'm the person asks my questions over and over again until I get the answer I'm looking for. No one who had those answers. I had answers from here and eIC that it's not possible. It is possible, but as long as that person was once had a working jailbreak using Cydia before. I had it, but I upgraded to iOS 6.0.1. This is how you go back to iOS 5.1.1 without SHSH blobs, and yes, I swear it works. Trust me.

First jailbreak the iOS 6.0.1 using the iOS 6.0 IPSW, and I used redsn0w for that. I did it the iOS 6 tethered by selecting the iOS 6.0 IPSW. Once done following this link I'm going to post.

That's it.
 
First problem with that is that the user's blobs on on Cydia. If they were not, it wouldn't work. Apple has gotten very smart about this and there is no way to downgrade to iOS 5.1.1 without going to iOS 4.X first. SHSH blobs are needed. They are a very hardset requirement and only Apple's signed copies will work. They cannot be generated out of thin air.

I got it to work fine without problems, and I didn't have my blobs saved.
 
This is NOT doing it without SHSH BLOBs. It's doing it WITH SHSH BLOBs that were saved on the Cydia server. And whether this will work depends entirely on what device and firmware you are currently on.

Yes, that's right. I didn't know how to save them manually, so I did a remote fetch off the Cydia server. I have the iPhone 4, so a while ago I upgraded, and didn't have a JB, and those instructions helped get a JB again.
 
So you did have your blobs saved. Just because you never saved them or jailbroke your phone, doesn't mean that someone else saved them. They can be saved without jailbreaking.
 
OP change your title, you downgraded with automatically saved blobs on Cydia.
So no it does not workwithout blobs.

In redsn0w you can choose, local or remote SHSH's, you used the remote ones, without those it is not possible
