Thread: Iphone 3gs Upgrade

    Default Iphone 3gs Upgrade
    I've done research but a questionable condition always arises. I have a iphone 3gs 3.1.2 spirit jb. I have the shsh for 3.1.3 saved on file and 4.0 on cydia. Is there a way to restore and upgrade if i dont have the shsh for 3.1.2?

    I'm certianly no expert, but the only reason you would need the 3.1.2 shsh on file is if you wanted to go back. Logic tells me that if you are restoring with, say 4.0, you are using the shsh and firmware for 4.0. I was on 3.1.3 and Spirit JB, and restored to 4.0.1 and used I followed this guide . Be sure you sync with itunes first (and backup) otherwise, when you restore, itunes will install your last backup. Another note, if you are spirit jb, you probably haven't upgraded itunes to 9.2, but firmware 4.0 and above needs 9.2. Good luck!
