Are you eagerly waiting for iOS 11.3.1 jailbreak? Well, many of you want to jailbreak your iPhone or iPad and customize the way you like.

Ahead of the release of Electra jailbreak for iOS 11.3.1, a new downgrade tool for iOS 11.3.1 has been released. You can downgrade to the previous version like iOS 11.3.1 even if you are currently running the latest version or betas. But for downgrade, you must have saved the SHSH blobs for this.
