    Hi,
    I have an iPhone 4 with iOS 7.1.2 and i want to downgrade to 5.1.1
    I have SHSH Blobs and i search a tutorial,
    All is for people who don't have shsh, but i have them and, when i try tutorial without SHSH, i have an error and i need to restore my iPhone to 7.1.2
    I hate iOS 7, it's not only because it's so slow, it's too because i'm nostalgic of iOS 4/5/6 and i really don't like iOS 7's design and i want to downgrade my iPhone to 5.1.1, how i can do this ?
    My 6.1.2's SHSH is not valid :(
    So i can only use 5.1.1's SHSH
    How to downgrade ?
    Thanks.
    (Sorry for my english mistake, i'm french and i'm not really bilingual)

    Once you go to iSO7, I don't believe there's a way to downgrade, even with the BLOBS saved.

    Sorry, but, iOS 7 really sucks on iPhone 4.

    You'd probably get a better response asking on the JB forums here and not in the general iPhone section.

    If you were using the iPhone 4s, I would say no. But there's a baseban vulnerability in the iPhone 5 that can make this possible - if you have that baseband. I don't know enough about that.

    Looks like you had it figured out, no reason to make this thread in the first place. My iPhone 4 works great on iOS 7, just a bit of lag here and there. (A4 processor is old!)

    People were just trying to help.

    That because when I asked, I could not do it. But now, it's worked. (i use google translate, it can not be accurate)
    Downgraded, and jailbreaked.

    Yes, it's true. but it's not only for this, it is also because there is not much to tweak for iOS 7
