64 Bit Software Downloads
TinyUmbrella is licensed as freeware for the Windows (32-bit and 64-bit) operating system / platform from iphone tools without restrictions. TinyUmbrella 9.3.4 is available to all software users as a free download (Freeware).
TinyUmbrella backs up your iOS firmware SHSH blobs and can restore them to downgrade your device to an older working firmware, proving to be a potential lifesaver whenever an iOS jailbreak operation fails. This program combines two earlier tools called Umbrella and TinyTSS.
Pros
Brings you peace of mind: TinyUmbrella effectively eliminates the risks associated with jailbreaking an iOS device by saving your firmware and sending it to a remote server from where it can always be restored.
Accessible: Even if you're not tech-savvy, you should be able to use this app without any problems. The clean and straightforward interface makes everything easy.

iTunes can be used for restores: If for some reason the remote server is down, the iOS downgrade can be facilitated through iTunes.
Cons
SHSH blobs cannot always be retrieved: Apple will not allow SHSH blobs to be retrieved indefinitely, allocating only a limited time window for signing a specific update. In this scenario, this program may display a 'You are too late' message, which means that you have to jailbreak your device without any safety net.
Bottom Line
As a single-minded utility, TinyUmbrella does its job well, restoring your iOS device to its previous working firmware version without any issues. It's well-made and manages to accomplish what it proposes without bugs, glitches, or other issues. Bear in mind, though, that as new devices and iOS versions appear, it is important to look out for the corresponding newly released versions of this software.
