Dopamine Jailbreak 2.1 is now officially released. The most recent release of the rootless jailbreak adds support for new devices and fixes spinlock panics on jailbroken environments.


  • The most recent release of Dopamine 2.1 brings support for A8(X) devices.
  • Dopamine is a semi-tethered rootless jailbreak for iOS 15 – iOS 16.6.1, and requires to re-jailbreak the iDevice when the device is restarted or the battery is drained.
  • To jailbreak A9(X) and later devices on iOS 15.0 to 16.5, A9(X) to A14 and M1 devices on iOS 16.5.1, and A9(X) to A11 devices on iOS 16.6 to 16.6.1, you can use Dopamine.
  • Since release 2.0, Dopamine brings support for more iPhones; arm64e devices on iOS 15.0 - 16.5.1 and arm64 devices on iOS 15.0 - 16.6.1.
  • The jailbreak was distributed as TIPA package for TrollStore, and a standard IPA package that can be sideloaded with any IPA installer.
  • Dopamine 2 can jailbreak devices spinning from iPhone 6s to iPhone 14 running on iOS 15 to iOS 16. View the 'Supported devices' list for details.


With TrollStore, you can permanently sign Dopamine 2.1, eliminating the hassle of signing in every 7 days. In contrast, methods like AltStore or Sideloady require you to sign the IPA again periodically. However, you can download Dopamine IPA and sign it with a different method.

What is Dopamine?

Dopamine Jailbreak 2.1 enables users to jailbreak all modern iOS devices running iOS 15 – iOS 16.6.1, including A12+ models. The jailbreak's creator, Lars Fröder, has expanded upon the original Fugu15 proof of concept that was first released by Linus Henze. It uses Sileo as the default package manager and ElleKit as a tweak injection library. It supports 15.0 – 16.6.1 arm64 (A9+ for now), 15.0 – 16.5.1 on A12 - A14, and 15.0 – 16.5 on A15 - A16.

Dopamine Jailbreak 2.0 sets itself apart from its predecessor, by offering enhanced functionality through the addition of tweak injection support and improved exploit performance. While this feature is still under development and not yet functional, Dopamine 2.1 Jailbreak has been designed with end-users in mind, providing them with the ability to utilize Sileo or Zebra and install rootless tweaks on iOS 15 that are specifically tailored for rootless jailbreaks.

Although Dopamine 2.1 has made significant strides in improving its functionality, it still requires Wi-Fi to be disabled during the jailbreaking process on iOS 15.0 – iOS 15.3.1. Nevertheless, a new commit has been introduced, which allows Wi-Fi to be re-enabled after the jailbreak is complete. As Dopamine 2.0 Jailbreak continues to mature, this feature will be automatically handled by the app, thanks to arbitrary entitlements.

Dopamine 2.0 was released

Dopamine 2.1 Jailbreak has recently undergone significant enhancements and upgrades, offering users a host of new features. One of the most notable updates is the new GUI, which can greatly improve the functionality of the jailbreak. Additionally, the latest release has resolved several issues that were impacting users, such as AutoFill not working properly after respring, and certain device combinations not being supported.

The jailbreak's bootstrap has also been updated to the latest version, and the system-wide hook has been improved to always respect safe mode, ensuring that the library is kept out of DriverKit and BlastDoor processes. Additionally, the latest version of the Dopamine IPA Jailbreak prevents tweak injection into processes that could use fork, further bolstering the jailbreak's stability.

Rootless repositories and tweaks

Dopamine 2.1 Jailbreak also comes equipped with default rootless repos, including Chariz, Havoc, Ellekit, Procurus, zp's rootless repo, and BigBoss. In addition, the jailbreak has addressed memory leaks in jailbreakd and now properly fixes SSH as mobile. Another notable addition is the jbupdate functionality, allowing for easy updating of the jailbreak.

The launchd hook has also been updated, with fallback ElleKit properly implemented using rpaths. Additionally, more XinaA15 leftover files have been deleted on jailbreak to make a clean installation. Lastly, the latest release includes numerous stability improvements.

Dopamine Jailbreak offers tweak injection capabilities via the ElleKit tweak hooking library. The app itself will allow users to select the preferred package manager, restart Springboard, and reboot Userspace. From jailbreak settings, users can enable tweak injection, iDownload, and verbose logs. Moreover, there is an option to temporarily hide or remove the jailbreak.

Note: When installing Dopamine IPA and executing the jailbreak it will remove all repositories and tweaks installed on your device using Fugu15 Max Beta.

Dopamine Updates

The most recent release of Dopamine Jailbreak introduces a range of significant enhancements and improvements. Notably, the performance of PPLRW has been dramatically boosted by a factor of approximately 1000x. Additionally, a new watchdogd hook has been implemented to intercept userspace panics, enhancing stability and reliability.

In terms of organization and functionality, iDownload has undergone a thorough refactor and now operates as its dedicated daemon. Furthermore, an issue with jbctl, where debugged flags were not being set correctly, has been resolved, ensuring accurate debugging.

What's new

  • Fix App Switcher not displaying preview images of jailbreak apps in some cases [2.1 regression].
  • Sandbox: Allow writing to /var/jb/var/mobile system wide.
  • Add support for A8(X) devices.
  • Fix Dopamine app instantly crashing when installed using TrollStore on A8 devices.
  • Add kcall implementation on arm64 iOS 15.x (this was needed for A8 support).
  • Use kcall for allocating page tables when available.
  • Improve performance of some parts of the jailbreaking process by ~1000x.
  • Add weightBufs and multicast_bytecopy as Kernel exploit options.
  • Add 'Allow JIT in Apps' toggle, enabled by default.Fix jailbreaking not working when developer mode was disabled (Developer mode will now be enabled in a non persistent way for the current boot).
  • Fix NECP connections failing after some time on arm64 (Apple Watch, VPN...).
  • Fix terminusd crashes on arm64, reenable injection into it and nesessionmanager.
  • Automatically fix wrong permissions for /private and /private/preboot when jailbreaking.
  • Fix app icons disappearing or no longer opening on OTA updates (Will only be fixed for future updates, not for the one to 2.0.10, also requires TrollStore 2.0.13).

To enhance iOS compatibility, the release discontinues the use of installed ellekit dylib for launchd hook. Moreover, efforts have been made to improve the Wi-Fi disabling code, resulting in a more effective preservation of the Wi-Fi state before initiating the jailbreak attempt.

In addition to these improvements, several compiler optimizations have been enabled for base binaries, leading to enhanced performance and speed. Furthermore, the release includes localization updates. Download Dopamine Jailbreak IPA is available at the top of this page.

One of the major improvements is the transition from the old PPLRW method to a new PPLRW approach. This new method involves mapping the entire kernel physical address space into the userland process. This change successfully resolves various lingering issues with PPLRW, including problems with multithreading support and TLB (Translation Lookaside Buffer) issues.

Another notable addition is the reenabling of the launchd crash reporter. This is done in a manner that cannot be detected by apps, ensuring greater stability and reliability. To improve user experience, the jailbreak button for uninstallation is now hidden while the device is jailbroken. This decision was made because the button's functionality was not working correctly in the jailbroken state. Consequently, it will only be visible and accessible in unjailbroken mode.

Additionally, the Dopamine Jailbreak for iOS 15 contains a fix applied to address the issue with the iDownload option, which has not functioning properly since version 1.1. This issue arose due to a codesigning error in the idownloadd binary, and the development team apologizes for any inconvenience caused by this oversight. Always install the latest Dopamine IPA.

KFD version of Dopamine Jailbreak

The experimental beta version of Dopamine KFD, features a significant change: it utilizes KFD instead of oobPCI. At the moment, this version serves as a secondary build due to the PAC bypass appearing somewhat less reliable. Please note that progress updates and verbose logs during PAC and PPL bypass are currently unavailable.

This new build extends support for iOS 15.5b1 – iOS 15.5b3 and eliminates the requirement for the Wi-Fi fixup on iOS 15 – iOS 15.1.1. However, it's essential to mention that an upcoming Dopamine release will introduce an exploit picker. Consider this version as a temporary solution, bridging the gap until the release of the comprehensive version, which is still in development.

It's crucial to understand that the post-jailbreak environment remains unchanged; stability will not be affected. The only difference lies in the exploitation process, which has been modified for this experimental beta version. Stay tuned for further updates and improvements.
