What is Fugu15 Max?

Fugu15 Max is a recently developed jailbreak that aims to enable jailbreaking on all modern iOS devices running iOS 15 – iOS 15.4.1, including A12+ models. The creator of this jailbreak, Lars Fröder, has built upon the original Fugu15 proof of concept that was released by Linus Henze.

Fugu15 Max differs from its predecessor, Fugu15, by providing enhanced functionality through the addition of tweak injection support and improved exploit performance. This feature is still under development and doesn't work yet. Notably, Fugu15 Max was designed with end-users in mind, enabling them to utilize Sileo and install tweaks specifically tailored for rootless jailbreaks.

Fugu15 Max was limited to iOS 15.4 – iOS 15.4.1, as userspace rebooting on earlier versions can trigger a Wi-Fi bug panic, even when Wi-Fi is disabled. This issue is present in the Fugu15 jailbreak, with versions 15.0 through 15.3.1 exhibiting similar device freezing and restarts. Recently, the bug was fixed allowing Fugu15 Max to support iOS 15.0 – iOS 15.4.1.

Despite the advancements made in Fugu15 Max, it still requires the disabling of Wi-Fi during the jailbreaking process. However, with the introduction of a new commit, Wi-Fi can now be re-enabled once the jailbreak is complete. As Fugu15 Max matures, this feature will be automatically handled by the app, thanks to arbitrary entitlements.

Currently, there is limited information available about the Fugu15 Max jailbreak. The official GitHub page suggests that Lars began modifying the Fugu15 source code in February, but additional details remain scarce. It is possible that other developers will contribute to expedite the development process or even discover a means to enable the jailbreak to provide even more features. As for now, Fugu15 Max will work on iOS 15.0 – iOS 15.4.1.

Fugu15 Max seeks to establish itself as a conventional jailbreak with tweak injection capabilities via the Ellekit tweak hooking library, although an expected release date has not yet been announced. If the jailbreak will be released to the public the article will get an update.

While the source code for Fugu15 Max is currently available for compilation, the jailbreak does not yet support tweak injection, rendering it impractical for end-users. The jailbreak will be made available as an IPA package that can be installed permanently with TrollStore.
