Last weekend, Electra jailbreak tool announced full support for other Apple devices equipped with the iOS 11.2~11.3.1 system.
In the afternoon of July 10th, Electra 1.0.3 added iOS 11.4 jailbreak support for iPhone X, iPhone 8, iPhone 8 Plus, iPhone 7 and iPhone 7 Plus. Official website link.
Although the system version is iOS 11.4, however, the jailbreaking is possible up to iOS 11.4 Beta 3, because the vulnerability required for jailbreak was blocked by Apple after Beta 3.
Currently, Apple still in the process of patching the iOS 11.4 Beta 1/2/3 jailbreak vulnerabilities, so right now, the users can freely brush the firmware.
Although the verification code copying, shortcut switch and other necessary functions of jailbreak have been integrated into the system, still some users want free installation of software after the jailbreak, modify the interface, etc.
