SHSH/SHSH2 Blobs (ECID Hashing Formulas)
Saving SHSH2 Blobs, which are the hashing formulas that are a small piece of data that is a part of Apple’s digital signature. These refer to the device’s ECID, a unique identification number embedded in the device’s hardware. Apple developed these to control the iOS versions that Apple users can install on their devices.
All the SHSH blobs process is controlled by TATSU (TSS). These are necessary to downgrade or upgrade to the newest iOS firmware versions in the future if certain conditions are met. The updates can only be completed using iTunes; Apple has developed these digital signatures to use to personalize IPSW or iOS firmware files for each device Apple has created.
You can go to previous iOS versions which are not being signed by Apple without any restrictions on your iPhones, iPads, iPod touches, and Apple TVs after you save signed hash or SHSH blobs for these devices. iOS developers have made tools for this process, and in this article, we are using TSS Saver (TATSU) tool to save SHSH blobs; these blobs are also called ECID SHSH or signed hash
