Is it possible to roll back iPhone from ios 8.3 to ios 7.1.1?

Question

iPhone

I tried to roll back through a backup, error 3194 popped up. Maybe he knows more ways to roll back?

Answer 1

If there is no shsh, then in any way, as far as I know.
If you didn’t save them before, when apple signed the firmware or you didn’t have a jailbreak on 7.1.1, then most likely you definitely don’t have shsh and you won’t get them anyway.

Answer 2

No way. 7.1.1 not signed by Apple certificate for a long time
