Exploits for iOS 11.3.1 were released online quite a while ago. Since then, people have been eagerly awaiting a new jailbreak for iOS 11. CoolStar, known for the iOS 11.0 – 11.1.2 Electra jailbreak, has been working on an updated version of Electra recently that would support iOS versions 11.2 through to 11.3.1. After a long wait, that jailbreak has finally been released!

As with all jailbreaks over the past couple years, this is also a semi-tethered jailbreak. This means whenever you reboot your device you will need to follow steps 9 and 10 of the below guide to restore all jailbreak features. This is very easy though so isn’t a big problem. This new jailbreak is compatible with all devices that can run iOS 11. As with most jailbreaks released over the last few years, this one can also be achieved without a computer simply by downloading the Electra app from a website such as Tweakbox or AppValley. You should defiantly make sure to backup your device to iCloud or iTunes before attempting this.
