Use TinyUmbrella To Save SHSH Blobs For iOS 8.3 – How To

Today marks the day of Apple's iOS 8.4 release along with Apple Music but what if you change your mind to downgrade to the current version, iOS 8.3. The technique involves saving iOS 8.3 SHSH blobs so you can use them later on to downgrade to iOS 8.3, even when Apple stops signing firmware for the respective version. To avoid jailbreaks, Apple always restores your device to the current version.

This is usually adopted by users who wish to downgrade their firmware for jailbreak. Hence,  when Apple stops signing the iOS versions, you can use these blobs to downgrade your iOS and create a pre-signed IPSW file using the RedSn0w tool. Not so long ago, Apple patched all vulnerabilities that allowed users to downgrade to the previous or older version of iOS. Devices Devices include iPhone 4S or later  or iOS 7 and higher. Thus, there is no way you can use SHSH blobs to restore to iOS 6.x or higher apart from iPhone 4, iPhone 3GS, iPod Touch 4G and iPad 2.

Save SHSH Blobs For iOS 8.3 Using The TinyUmbrella Tool

There are always exploits in the system, so with all thanks to iH8sn0w, SHSH blobs are relevant again to use for later versions as well. So if Jailbreak is not possible on iOS 8.4 version, users can always downgrade to iOS 8.3 using SHSH blobs when Apple has denied signing the previous version. So lets get on to it.
