    Hi, download tinyumbrella, open it up and then connect your device and then tick "Advanced options" and request the version you need (the 4.0 SHSH blobs). When it has retrieved the blobs from Saurik's server (Cydia), just click "Start TSS server" and simply restore using iTunes.

    They should be on Saurik's Server if you have jailbroken your device before... Did you retrieve your SHSH blobs directly from Apple?
