    I want to upgrade my iPhone 4 to iOS 6.1.2 from iOS 5.0.1. I have tried using blobs to stitch an ipa and i am still getting an error. I have tried using TSS servers. I am just confused how to do it. Please help.

    Thanks in advance.

    Use iFaith to check your blobs. My 6.1 and 6.1.2 blobs were invalid.

    Download the latest version of iFaith (v1.5.6) and run it. Plug in your iPhone 4 and click "show available shsh caches on server". After it finds it, save them.

    See if it marks them as valid or not. If its not valid, don't upgrade or else it'll put your device into a DFU loop (or so I heard)

    As the previous user said, they're probably not valid
