iOS 11.2.5 SEP Compatible With iOS 11.1.2, Which Means You Can Lose It From To Jailbreak Purposes

The good news in jailbreak community does not always come in the form of a new jailbreak tool release for Apple devices and firmware. Positive news has been widely circulated in recent weeks and continues with the knowledge that the latest version of the FutureRestore tool lets those who require SHSH2 blobs from iOS 11.1.2 are saved to downgrade their firmware from the latest public iOS release.

We have tested and can confirm that the FurtureRestore 173 version will allow users to downgrade, restore, or upgrade directly to iOS 11.0 to iOS 11.1.2 from Apple's latest public version of iOS 11.2.5.

This is possible because Secure Enclave Processor (SEP) with iOS 11.2.5 does not change with the update, making it selected downgrade / re-restore possible on iOS 11.1.2. Of course, if you have the foresight to store your SHSH2 blob for iOS 11.1.2 when Apple is still signing it and before upgrading to iOS 11.2.5, it will not be lost when jailbreaking because this particular route will allow you to using iOS iOS 11.2.5 devices that are compatible with yours and then down to 11.2.5 and then jailbreak using tools like Electra CoolStar.

FutureRestore versions that have been tested and compatible, packaged as v173, can be obtained from the official GitHub page for the application here.

It's been a funny past in the jailbreak community lately. Many tools have been released to unblock devices in iOS 10.3.3 and iOS 11.0 to iOS 11.1.2 but still do not feel like we are running standards set a few years ago. That's probably because jailbreaks took so long to become there, and, even then, they're not what we call a "complete jailbreak" because there's still no Cydia or Substrate updates where iOS 11 is linked.
