Will It Be Possible to Downgrade with SHSH Blobs Saved for iOS 8.1.3 and 8.2 with TinyUmbrella?

You know that Apple stops signing its firmwares once in a while making it impossible to downgrade to previous iOS releases. TinyUmbrella iOS 8.2 release could make downgrade possible for iOS 8.1.3 and 8.2, in the future, as developer states. This program was highly popular years ago, but its creator stopped upgrading it until now.

It is currently impossible to save SHSH blobs 8.1.3 or 8.2 but such a capability can exist in the future. Right now TinyUmbrella exists in beta version. According to its developer Semaphore who is also known as @notcom, his program was completely rewritten from scratch so it should be easier to use the program.

The possibility of TinyUmbrella iOS 8 downgrade is awesome as Apple allows only restoring the iPhone or iPad to the version it signs. For example, the company stopped signing iOS 8.2 beta 1 and 2 meaning that users who accidentally updated to iOS 8.2 public version cannot change the situation and downgrade to 8.2. beta 2 [this is the only beta that has no expiration date]. As a result, users cannot use PP Jailbreak and TaiG to jailbreak earlier firmwares that are no longer signed even though it is possible to download ipsw files for the jailbreakable iOS versions.

The Cupertino-based giant doesn’t share SHSH blobs with users. You will be able to save SHSH blobs for iOS 8.2 or 8.1.3 using TinyUmbrella as this program can make pre-signed ipsw which can be then used for iPhone restoring to firmware versions that are no longer signed by Apple. We speak in the future tense because right now there is no way to use SHSH blobs for iPhone 4S, 5, 5c, 5S, 6 and 6 Plus in order to downgrade because the manufacture patched the loophole used for this.

Hackers hope that someone would develop a tool that can hack the restore procedure and use ipsw file created by TinyUmbrella or other similar programs to use SHSH blobs for downgrade.

You can still download TinyUmbrella beta for 8.2 update to save your blobs. This happens automatically thanks to the improvements brought by Semaphore. It is possible to save SHSH on any iDevice model for iOS 8.2 which is the most recent public update of Apple mobile OS.

Hopefully, the ability to downgrade will be available to users in the future. For now, save your SHSHs and wait for updates.
