Most people are aware of the name TinyUmbrella and many have used it in the past, in particular, jailbreakers. TinyUmbrella is a very powerful utility that saves your SHSH blobs for you. It used to be used to help you to downgrade your firmware, back to one that could be jailbroken but, in 2011, Apple discovered and subsequently patched the loophole that the developers of the tool were using. As of now, although you can still save your SHSH blobs, you cannot use them to downgrade.

How TinyUmbrella Works
The SHSH blobs that TinyUmbrella [ext link] saves are kind of markers, telling Apple which version of the iOS firmware your iOS device is using. Before 2011, jailbreakers would save their SHSH blobs every time they upgraded their firmware. This meant that, if they were running a jailbreak and a new iOS update came along, they could safely upgrade to it and see what it was all about. If they didn’t like it or there was no jailbreak available for it, they could easily downgrade back to when they could jailbreak.
Right now, we cannot use TinyUmbrella to downgrade but we can still save our SHSH blobs with it. The tool developers are looking to updating it to support iOS 9 and iOS 10 for downgrading purposes – it already does for saving SHSH blobs. So, although you can’t use TinyUmbrella to its full extent yet you can, and should, start using it to save your blobs – sooner or later you are going to be able to use them again.
Steps to Using TinyUmbrella to Save SHSH Blobs
- Download TinyUmbrella [ext link] . Make sure you download the right version, depending on whether you are running Windows or OS X on your computer
- Download Java if you don’t already have it because TinyUmbrella needs it to run
- Plug your device into your computer and wait – TinyUmbrella needs to detect it
- As soon as TinyUmbrella has successfully detected your iPhone or iPad, it will automatically download the SHSH blobs for you
That’s it, that’s all you have to do
Things to Remember
- First, TinyUmbrella can only download the blobs for the current iOS and any that are still being signed by Apple
- No matter how often you download your blobs, they will all be saved to one file for easy access – ~/.tu/.shsh
- Note that there are 3 types of SHSH blobs – Update, Erase, and OTA
- TinyUmbrella saves known devices to one file as well – ~/.tu/.known_devices
