check shsh2 blob validay for ios downgrade to unsigned version

iOS Jailbreak is tricky but equally alluring business. Constant ups and downs in the iOS jailbreak status keeps everyone interested in the process on their toes. Apple and iOS jailbreak community have been locked in tussle for supremacy for years now. Each try to pull off moves to out-do each other. As soon as a jailbreak exploit is released, Apple quickly marshals its resources to plug the loophole that allowed iOS to get jailbroken. Jailbreak is like root on Android. It allows you free your iPhone, iPad, or iPod Touch from the tightly control environment of the iOS regarding what can and can’t be installed on your device. Android is famous for its open-end platform that allows users to tweak and customize their deices. Opposite is the case with iOS, where Apple keep control over much of the firmware feature to prevent any attempt at customizing its iOS firmware.

Shsh2 blobs and iOS jailbreak go hand in hand. You need shsh2 blobs for the iOS firmware version which is no longer singed by Apple. And once Apple stops signing a firmware, you cannot downgrade your device on to it for jailbreaking iOS. Sometime, in a rush to try new iOS upgrades, you immediately upgrade your device to the latest iOS version, only to find later that Apple has stopped digitally signing previous version. Which can cause considerable headache for the fans of iOS jailbreak if the jailbreak tweak is released that works only on the iOS version that Apple no longer signs and officially supports. This is where shsh2 blobs come to the rescue, as they allow you to roll back your device to the previous iOS versions even if its isn’t signed by Apple anymore. Which in turn makes it possible for users to enable jailbreak on iOS version even if its not supported by Apple officially. However, shsh2 blobs are not without their limitations, check out more information on it in our Prometheus post.
