CoolStar has successfully jailbroken iOS 11.3.1. The hacker posted images of his jailbroken iPad on Twitter today, showing Cydia and Anemone (a theming engine) installed.
Cydia is broken on 11.3.1 and it’s rather buggy but code injection and the rootfs remount works
Electra can now fully jailbreak iOS 11.2-11.2.6. Then main issue right now is with the rootfs remount, once fixed Electra will work up to iOS 11.3.1.
Previously, it was thought that the jailbreak would require a developer account but this is no longer the case.
$۹۹ developer account will not be required for jailbreaking iOS 11.3.1 after all
