Downgrade firmware of your iOS devices to an earlier version to restore them to their previous state. Play back SHSH signatures for firmware restores, start the TSS Server and enable iTunes to continue the restore. Fix issues related to your iPhone or iPad stuck in Recovery mode, fixing iTunes Error 3194, etc.

TinyUmbrella facilitates the process of restoring your iPhone's iOS, and is also useful for jailbreaking the device. It does two things: Requests SHSH signatures for firmware restores Plays back those signatures enabling iTunes to continue the restore TinyUmbrella sends the same exact request that iTunes sends Apple when requesting the signatures for your device to be restored. The difference is that TinyUmbrella does not need to do anything to your device. You do not need to be on the firmware version that TinyUmbrella is requesting signatures. As an example, I've been on 3.1.2 for quite some time. TinyUmbrella has saved my 3.1, 3.1.2 and 3.1.3 signatures. This is because the request that iTunes sends to Apple includes your ECID and the details about the firmware version. Apple sends the response signatures and TinyUmbrella saves them so you can use them whenever you want; Even if Apple has stopped signing that particular version.
