This tool helps create SHSH blobs for Apple iOS8 devices.
Tinyumbrella is a tool to create iOS8 SHSH blobs and downgrade iOS8 running devices into jailbreakable iOS version. If you need to downgrade your iPhone, iPad or iPod, this is a tool you are going to need. The tool works in Windows platform. It is always safer to create a back-up of your data that you have already on the device before you attempt to create the SHSH blobs or jailbreaking of the device. SHSH blob is a small piece of data that is part of Apple`s digital signature protocol. It is designed to control the iOS versions that users can install on their iOS devices. The protocol is such that typically the newest iOS version are installable. Developers interested in iOS jailbreaking will need to use this tool and make lower versions installable so that one could create a jailbreak version of the device.
Though intended to take you through the whole process, this software currently is able to create only the SHSH blobs, no downgrading. This is promised for a later version of the tool. With that upgrade, users will be able to complete the processes necessary to create a jailbroken device from the current iOS based device. Besides downloading the tool, you will need to install the JRE 8 on your PC. You then connect the device and the TinyUmbrella will recognize the device. The utility then will download all available SHSH blobs after device recognition. The downgrade process follows automatically.
