A new KPPLess jailbreak has just been released by Coolstar. This new jailbreak, called Electra, makes use of a modified version of Substitute by comex. With this, the jailbreak is able to offer the same functionality that saurik’s Cydia Substrate used to provide. In a nutshell, this means that most binaries, tweaks, and apps will not operate until they have been updated. Before you install anything from Cydia, see to it that you check its compatibility. You can find the full list here.
What You Need to Know
There are some important things you need to know about this jailbreak. The first thing is that it creates an APFS snapshot so you can opt to revert to it at a later date if it is required. If you encounter any blobs prior to running Electra, it is recommended to future restore so you have the best installation experience.
The jailbreak also includes Cydia and Electra repo by default. This means you can add Substitute, Substrate Compatibility Layer, and Tweak Layer. It is also running OpenSSH on port 22. In order to make the most out of the installation, you need to update the packages for both iOS 11 and Electra. The jailbreak also requires at least RocketBootstrap 1.0.6 or higher on the operating system version.
You may also encounter broken apps, installation binaries, and launch daemons as they may require additional entitlements.
If you decide to jailbreak using Electra, you have to be aware that everything on saurik’s repo is currently broken on iOS 11. When you encounter an “APT 0.7 Strict” update or package on the iOS version, do not update it. This is purely for saurik’s repo.
Right now, saurik has turned down the option of using a jailbreak daemon. Instead, he has confirmed that he is working with a famous developer to release the jailbroken version of iOS 11.0 – 11.1.2; both of which will include a functioning Cydia and Cydia Substrate. However, there is no word on when these will be available.
Nevertheless, there’s a way for you to download the Electra jailbreak so you can test it out yourself. You will need to install it on your device with the help of Cydia Impactor and your current Apple ID account. If you’re not a developer though, you won’t be able to sign the app for a week’s time. After this, you’ll need to sign it using Cydia Impactor once again.
The jailbreak is compatible with various iPhone, iPad, iPad mini, and iPod touch models operating on iOS 11.0-11.1.2.
