Yesterday, the developer Coolstar, as well as the Electra team, officially rolled out Electra Jailbreak v1.0.3 update, which will add support for iOS 11.4 beta version since Apple still allows signing the iOS 11.4 beta 3, beta 2 for iPhone X, iPhone 8 Plus, iPhone 8, iPhone 7 and iPhone 7 Plus models
It means if you accidentally updated your iOS device to iOS 11.4 or iOS 11.4.1 version, then you are still able to downgrade to iOS 11.4 beta and jailbreak your device using Electra Jailbreak file if you are using iPhone X, iPhone 8 Plus, iPhone 8, iPhone 7 Plus or iPhone 7. However, unfortunately, Apple is likely to stop signing iOS 11.4 beta for the other older iOS devices, including iPhone 6S Plus, iPhone 6S, iPhone SE, iPhone 6 Plus, iPhone 6 and iPhone 5S.
Here’s the full changelog for Electra Jailbreak v1.0.3 update:
Add support for 11.4 beta 1, beta 2, beta 3 (only tested on these firmwares)
Since Apple has already fixed the vulnerability used in the Electra Jailbreak for iOS 11.3.1 – iOS 11.2 in iOS 11.4 version, which has been rolled out to the public, so you cannot use Electra Jailbreak v1.0.3 update to jailbreak iOS 11.2-iOS 11.3.1. So, you will have to downgrade to iOS 11.4 beta 1, beta 2 or beta 3 to use it.
The latest version of Electra Jailbreak, which adds support for iOS 11.4 beta 1 – iOS 11.4 beta 3 can be downloaded from coolstar’s website.
How to Jailbreak IOS 11.4 Beta Using Electra 1.0.3 Jailbreak File
Here is a detailed instruction to jailbreak your iOS device running iOS 11.4 beta 1-beta 3 versions with Electra jailbreak 1.0.3 file. Simply follow the below steps to jailbreak your iOS device:
Step 1: First, download and extract Cydia Impactor software from its official page.
Step 2: Download the latest Electra jailbreak file as the link above.
Step 3: Connect your iOS device to the computer and then open Cydia Impactor. Then, drag & drop the downloaded Electra jailbreak ipa file into the Impactor window. When you are prompted, simply enter your Apple ID & password.
Step 4: Now, click on Start button and wait till the process to be done. Once completed, you should not open the app on your device yet. Instead, you need to trust the app first.
Step 5: Now, trust the certificate by going to Setting –> General –> Profiles & Device management (Profiles) and tap on Electra Profile and trust it
Step 6: Once you trust the app, return to the home screen, launch Electra app and tap on the jailbreak button.
During the jailbreak process, your phone will reboot several times and after the final reboot, you will see the Cydia icon on your device running iOS 11.4 beta.
Unlike the initial Electra version rolled out for the iOS 11.0.x to 11.1.2, the latest Electra 1.0.3 jailbreak includes Cydia as a part of the payload. Moreover, it also comes with the Substitute framework, which is a Comex crafted replacement for the Substrate. Once jailbroken, you can instantly access Cydia and install your favorite tweaks.
