Semaphore has reinvented TinyUmbrella, the tool that lets iOS users downgrade to previous iOS firmware. This amazing tool allows you to save SHSH blobs for your iOS device to help you downgrade. The reinvigorated TinyUmbrella is in beta version now and is compatible with OS X and Windows.
Had Apple allowed the access to SHSH blobs, iOS users could efficiently downgrade their firmware. However, Apple doesn’t do so with a view to protecting iOS from jailbreak community.
Can Download Only Those SHSH Blobs For The Firmware Which Apple Signs
TinyUmbrella can download the blobs which Apple currently signs. Therefore, if you are unable to download iOS 8.1.2 and didn’t know why it’s not able to do it, the simple reason is Apple has stopped signing it.
Three Kinds of SHSH Blobs
There are three kinds of SHSH blobs which can be viewed in TinyUmbrella beta. They are:
#1. Update (Restore)
#2. Erase (Restore)
All these three blobs have been recognized in the list of blobs named as Type column.
Where Can I Find SHSH Blobs On My Computer?

Can I Remove TinyUmbrella History?
TinyUmbrella keeps a record of the devices that have been connected to it. It continues to download the SHSH blobs from Apple server even when your iPhone is not connected to it.

As of Now Downgrade Not Possible
You can’t downgrade your iOS firmware as of now. Nevertheless, you can download the SHSH blobs which are currently signed by Apple.
