TinyUmbrella is one of the most popular tools used by jailbreakers in many years and one of the most useful. It is a tool that we used to use to help us downgrade our firmware version when we wanted to jailbreak on an older version of iOS. For those who have never used it, TinyUmbrella may be small but it is an incredibly powerful piece of it and it is one that we should all have at our disposal.

How Does TinyUmbrella Work ?
Tinyumbrella uses something called SHSH blobs – these are what Apple uses when it wants to verify which iOS version you are using on your device. Up until 2011, it was one of the most used tools around, until Apple patched the holes it used, leaving us somewhat stranded. Jailbreakers used to use it to save their SHSH blobs before they upgraded their firmware. That way, if there was no jailbreak available for the new firmware they could downgrade again and reinstall the old jailbreak.
At the moment, there is no way to use TinyUmbrella to downgrade but the developers are working on an update that will work on both iOS 9 and iOS 10, meaning that, very soon, we will once again be able to downgrade our firmware versions at will. Although you can’t downgrade, you should still install TinyUmbrella [ext link] and start saving your SHSH blobs once again. You never know when you might be able to use them again.
Using TinyUmbrella :
Here’s how to use TinyUmbrella to save your SHSH blobs, ready for when we can use the tool to downgrade again:
- Download Tinyumbrella [ext link]. Get the correct version of TinyUmbrella for your system, running Windows or Mac OSX .
- If you haven’t already got Java on your PC or Mac, download it now. You will need it for TinyUmbrella to work
- Open TinyUmbrella
- Using your lightning cable, connect up your iPhone or iPad to your computer
- Wait a minute – TinyUmbrella needs to detect your device before you can go any further
- As soon as your iOS device has been successfully detected, all SHSH blobs will be downloaded and saved automatically. You don’t need to do anything else
Things to Note :
- If you are running a version of the iOS firmware that Apple is no longer signing, TinyUmbrella will not download any SHSH blobs because there are none to download
- All of the SHSH blobs from your device are saved into one file, no matter how many versions you download – ~/.tu/.shsh
- You will see that there are three different types of SHSH blobs – OTA, Erase, and Update
- TinyUmbrella also saves known device details into one folder so if you use more than one device, you only need to look in one place for the blobs – ~/.tu/.known_devices
Don’t wait for us to tell you when TinyUmbrella has been updated – start using it now to save your SHSH blobs in readiness. Just remember that you can’t use them to downgrade just yet.
