What is Electra Jailbreak?

Electra is a jailbreak tool for iOS 11 - iOS 11.4.1 based on async_wake, mach_swap, mach_swap2 exploits (voucher_swap & v1ntex are not used in the latest version). Once, jailbroken, you can download and install tweaks and apps from popular repositories through Cydia or Sileo.

The jailbreak is using libhooker library as Injection Library. Since version 2.0 Electra Jailbreak will select automatically the best exploit for your iPhone and iOS. This way the system will work more stable and at better performance without the need to do anything from the user.

What's more, there is also a tvOS Electra port created by nitoTV and Jaywalker allowing you to jailbreak tvOS 11. This jailbreak tool will allow you to install tweaks and unofficial apps on your Apple TV. You can for example install Kodi or Plex on your AppleTV.

Because this is a semi-untethered jailbreak after every restart of your iPhone or iPad the jailbreak will be removed. To change the state to jailbroken you need to re-jailbreak again your device with the app. When Electra app will not open you will also need to re-install it.

Electra Jailbreak features also basic dylib injection into a running process, mount / as rw, and amfi bypass to run unsigned code allowing you to install IPA files without revokes. The jailbreak supports also AppSync Unified, the popular IPA installation tool for iOS.​​​

Substitute, Tweak Loader, and Substrate Compatibility Layer are available from Electra Repo.

Before jailbreaking iOS 11 Electra will create an APFS snapshot so you may restore it at a later date. This is a great solution allowing you to back up the actual state of your device before jailbreaking. What's more, this feature is built into iOS and can be executed after re-jailbreak.

On top of that, Electra app installs OpenSSH running on port 22. This server runs on your device in the background and can be accessed from your computer using a terminal or an SSH client. Once connected to your iPhone, you can manage the device, install tweaks, copy files, etc.

The app is even packed with a "Set nonce generator". This feature is required to restore the iDevice to unsigned iOS firmware using futurerestore and saved blob files.

The initial release was working on iOS 11.0 - 11.1.2. Be aware that On iOS 11.3 - iOS 11.3.1, the device will reboot twice and Electra will need to be re-run after the first reboot.

Electra Jailbreak was the first tool released by @CoolStar to exploit iOS and it added something new to the jailbreak community. Later it becomes the foundation for other jailbreaks such as Taurine Jailbreak for iOS 14, Chimera jailbreak for iOS 12, and the Odyssey jailbreak for iOS 13.

Electra was created with stability and performance in mind, therefore this is one of the most stable jailbreak tools for iOS 11. If for some reason you would like to try a different jailbreak, the only one released next to Electra for iOS 11 was unc0ver, which works with iOS 11 - iOS 11.4.1.

With the release of Electra Jailbreak for iOS 11, @CoolStar introduced Sileo, a powerful APT client for iOS 11 that was and still is a great Cydia alternative. Since then Sileo was always the default package manager for other jailbreaks developed by the team.

How to jailbreak iOS 11

To jailbreak iOS 11 using Electra App it's simple. After you install the latest version of Electra 2.0 IPA on your iPhone you are just a few steps from jailbreaking and installing Cydia and Sileo 1.9.1.

  2. Tap on "Jailbreak" displayed in the main app window.
  3. Electra will execute all exploits to install the jailbreak.

Remove iOS 11 jailbreak

To remove jailbreak installed with Electra App you need to restore the automatic APFS snapshot created before jailbreak. Use apps like SnapBack or Succession to manage snapshots or if you prefer command-line tools to manage APFS on iOS install snaputil or snappy.

Re-signing IPA on-device

Because Electra app is sideloaded with a free certificate it will get revoked after 7-days. If you have access to a computer this is not a big issue, but if you don't you can use a jailbreak tool like ReProvision. It will automatically re-sign the app on your device before it gets revoked.

  1. Navigate to the top of this page to download Electra IPA.
  2. Tap on the "Install via ReProvision" button and tap Open.
  3. Electra IPA with the download and imported automatically.
  4. Tap on the Install button to sign and install the app.

Source Code

Electra Jailbreak Toolkit is created by the jailbreak community and was released as an open-source project with all files listed via GitHub Repository. You can build the project with 3 simple steps on macOS. Recent changes in the code were added on 13 Feb 2018.

As long as you have standard libraries for Xcode projects you are good to go. 73% of the code is written in C and 23% in Objective-C. Source Code is under GPL-3 Clause License. The jailbreak is no longer developed, but the source code is a great source to learn about exploit techniques.
