How to save SHSH blobs – A Complete Guide

I consider many of us already know the meaning of SHSH blobs but for a better clarity let us discuss the meaning of SHSH blob. So, what is a SHSH blob?

The answer is “A SHSH blob is something that apple uses to verify the version of iOS that is being used on the devices.” To know in detail let us consider this meaning “A SHSH blob is a word used for small pieces of data which are the part of apple’s digital signature protocol for iOS restores and updates which in turn is proposed to control the iOS update versions which a user install on their devices such as iPhones, iPods, iPods etc.”

Generally, an SHSH blob is not an official word. This word is used in behalf of digital signatures, which are developed by apple, and this is used to personalize files for each apple device. This is developed by a hashing formula, which has different keys. These keys include the device type, iOS version, and 13 digits ECID that is a device’s unique identification number embedded in the software.

Why do we need the SHSH blobs?

Actually SHSH blobs are very necessary for jailbreakers and for those too who unlock devices such as iPhone in particular because some of the jailbreak are only valid for an older versions.

Why do we need to save the SHSH blobs?

Whenever, a new method of jailbreak is developed. Apple launch its new iOS update and if we accept that new update without saving our old data we will not be allowed to jailbreak our devices such as iPhones, iPods etc. and if we want to downgrade our device to the older version or firmware the device it will be next to impossible for many of us. So this is the place where SHSH blobs comes into the picture and therefore, It is very important to save SHSH blobs because if we update our device to the new firmware and did not save the old SHSH blob so we will loose our entire jailbreak and we cannot downgrade to our old firmware again to jailbreak the device.
