A new TinyUmbrella beta is released with iOS downgrades in view

As promised, Semaphore has released a rewrite of his popular TinyUmbrella tool for OS X and Windows. The tool, which has been completely rewritten from the ground up, is currently in beta and requires Java.

Semaphore has alluded to the fact that the new TinyUmbrella may have far-reaching consequences related to downgrading both 32-bit and 64-bit devices. Back in the original TinyUmbrella’s heyday, it was used as a tool to help downgrade to prior versions of iOS.

Previously, saving SHSH blobs let you restore regardless of whether or not Apple was signing the firmware. For instance, if you needed to restore your phone, but the latest firmware was not jailbreakable (ex iOS 8.2), you could use your SHSH blobs to downgrade to a lower firmware version, or simply re-restore to a jailbreakable firmware (ex iOS 8.1.2).

Details are limited, so we aren't sure what semaphore has planned, but for now, a beta version of TinyUmbrella with limited features has been released in order to iron out various bugs before releasing a version with "more admirable features". Those "admirable features" are likely going to make saving SHSH blogs relevant again. Semaphore hints at the upcoming features on twitter, and even discusses working with @iH8sn0w on an exploit he discovered.

The new tool has been simplified significantly, and now contains a single button dedicated to saving your SHSH blobs. As you can see from the screenshot below, I have several blobs saved for both iOS 8.2 and iOS 8.1.3 for my iPhone 6 Plus:
