How to Save iOS SHSH2 Blobs

People who have been working with iOS jailbreaking are not strange with SHSH blobs. SHSH blob is a term for a small piece of data that is part of Apple's digital signature protocol for iOS restores and updates, designed to control the iOS versions that users can install on their iOS devices (iPhones, iPads, iPod touches, and Apple TVs).

Simply put, shsh blobs downloads will make it possible for you to upgrade or downgrade to using shsh2 blobs even it is stopped being signed by Apple. Therefore, we recommend that you download your iOS new SHSH blobs (SHSH2) while they are still being signed. Once the iOS 10.3.2/10.3.1/10.3 signing window is closed, you cannot save the SHSH2 blob any more. This means you can’t downgrade to this firmware.

TinyUmbrella was used to download SHSH blobs files for users to downgrade; unfortunately, this method of downgrading hasn’t worked for a few years now. In this article we will introduce a new tool TSS Saver that supports to automatically save SHSH2 blobs for signed firmware versions.
