Table of Contents

Latest Update: 
Public Beta 7
=>> Fix setuid properly, fixes NewTerm and probably other stuff too
=>> Transition to stable Sileo 2.4, only installed on new bootstraps however

Note* For already bootstrapped users, get the new Sileo deb from https://github.com/Sileo/Sileo/releases and install it manually

Download / Install

Public Beta 6

=>>Fix some memory corruptions in the systemwide and launchd hooks, should fix "initproc exited" random panic
=>> For some users, Sileo crashes on launch, there is no current fix or workaround for this, a proper fix is pending by Sileo developers
=>> On some versions, doing anything in Zebra crashes, there is no current fix or workaround for this, a proper fix is pending by Zebra developers
=>> When something hooks a C function system wide, userspace reboots will get stuck, the root cause for this is unknown=>> Spinlock panic, no idea what causes this, might be a late side effect by one of the exploits
=>> Some sort of race condition pmap panic, no idea what causes this either, but I think this is probably a bug in the environment somewhere
=>> On 15.0 - 15.3.1, you need to fully disable wifi while jailbreaking

Download / Install

Public Beta 5

=>> Add support for userspace reboots (NOTE: As this is still a beta mainly intended for developers, you have to manually userspace reboot after jailbreaking)
=>> Fix AutoFill not working after respring
=>> Fix function hooking and tweak injection into processes with very hard sandboxed (e.g. WebContent)
=>> Fix some device / version combinations not being supported (namely iPad 8 on 15.1)
Update bootstrap to latest
=>> Improve system wide hook to always respect safe mode and keep libary out of DriverKit and BlastDoor processes
=>> Prevent tweak injection into processes that could use fork, as hooking C functions in a process currently breaks fork from working, a proper fix for this is still pending
=>> Add default repos (Chariz, Havoc, Ellekit.space, BigBoss)
Fix memory leaks in jailbreakd
=>> Fixes SSH as mobile
jbupdate functionality, /var/jb/basebin/jbctl update tipa <path/to/Fugu15.tipa> or /var/jb/basebin/jbctl update basebin <path/to/basebin.tar>, note that updating to a TIPA also updates basebin but depends on TrollStore being installed on the device
Update fallback ellekit for launchd hook, properly implement fallback using rpaths
Delete more Xina leftover Xina files on jailbreak
Lots of stability improvmeents

Fugu15Max: iOS 15 -16.4.1? Jailbreak App Review:

Fugu15Max is an updated version of the Fugu 15 semi-untethered perma-signed jailbreak tool that supports iOS 15. It is based on code-signing bypass, kernel exploit, kernel PAC bypass, and PPL bypass. You can install Fugu15Max using the default Safari browser on your iPhone or iPad, so you don’t need a PC to install this jailbreak tool.

The main advantage of Fugu15Max is that it supports Tweak injection (via Ellekit), unlike the Fugu15 jailbreak. This means that you can now install Cydia, and Sileo tweaks after the jailbreak. Fugu15Max also contains an Automatic Trust Cache handling feature.

With this new feature, the jailbreak tool helps to manage the trust cache of third-party apps on a jailbroken iOS device, allowing them to run smoothly and without issues related to certificate validation. This means that after jailbreaking, you can install third-party apps without needing an Apple developer certificate.

According to the developer, this jailbreak tool is currently in development and is not recommended for new users who don’t know about the development progress.

But don’t worry if you don’t know how to use jailbreak and the method to jailbreak your device. Please read our blog posts as they may help you to understand the jailbreak subject well. Also, if you have any doubts about how to choose the best jailbreak tool according to your iPhone model and iOS version, use our AI-powered Jailbreak Finder for free.

Fugu15Max was developed based on an exploit discovered by LinusHenze. It is now possible to jailbreak iPhone/iPad models running iOS 15 using the Fugu15Max tool created by Opa333.
