iOS 11.3 is now out and its SEP is incompatible with iOS 11.0-11.1.2. This makes it your last chance to restore to iOS 11.0-11.1.2 using the SEP from iOS 11.2.6. Once iOS 11.2.6 is unsigned you’ll be out of luck, which could be any day now!
Electra is now fully released to the public and out of beta. Though some bugs have been reported, it has been a largely successful launch. If you’re feeling confident and ready to give it a try, check out this guide to learn how to jailbreak with and use Electra.
The clock is ticking on signing for iOS 11.1.1/11.1.2 and tvOS 11.0/11.1, so the pressure is on to save blobs for those firmwares, as well as to possibly restore to them. This doesn’t apply to everyone though, so check out our advice on the topic!
Update: tvOS 11.1 and iOS 11.1.2 are now unsigned. DO NOT ATTEMPT TO RESTORE TO THEM!
