I don't mean to come off wrong, but I highly doubt you have blobs saved. They're required to pull off the downgrade. I have a few 4S's and wish I would have saved at least one when we were doing things that way. Curious though, the desire to get back to 6 is common with 4S users. I had great luck with my jailbroken iOS 7-8 4s.... I even have one on 9 now. Although I don't use it, when I do, it seems ok. What's the main problem? Again, just curious ....
