Earlier in the day, we talked about iOS developer Mineek’s kfd exploit-based tweak injection project for RootHide’s Procursus bootstrap on non-jailbroken arm64e devices running iOS & iPadOS 16.0-16.6.1 called kfdfunv4. But what if we told you there was another?
Indeed, it now appears that iOS developer hrtowii has released a utility called Serotonin, and just like kfdfunv4, this is a kfd exploit-based tweak injection method that supports the RootHide development team’s Procursus bootstrap for non-jailbroken arm64e devices running iOS & iPadOS 16.2-16.6.1.
These tools are not full-fledged jailbreaks, but instead harness both the kfd exploit and the CoreTrust bug used by TrollStore to let you install and run certain jailbreak tweaks and hacks from the Sileo package manager app. In some Discord servers, these are being called “semi-jailbreaks.”
According to the Serotonin project’s GitHub page, the installation process looks something like this:
1) Download and install Bootstrap from RootHide
2) Install ElleKit from Sileo
3) Download the.tipafile from the latest release
4) Install the downloaded file in TrollStore
5) Open the app and press the Jelbrek button. Your device should userspace reboot, and you should be (not/semi) jailbroken!
It’s worth noting that these tools don’t support checkm8 devices (arm64), but that’s not really a problem given that checkm8 devices have the palera1n jailbreak to take advantage of and it will provide a much better user experience than any semi-jailbreak could ever hope to provide.
For what it’s worth, a PPL bypass proof of concept (PoC) for iOS & iPadOS 16-0-16.5.1 was just released, and it now seems like Dopamine v2.0 is due for a release in the next few months, so users may want to avoid running these non-jailbroken tweak injection hacks as they carry a risk of boot-looping your device.
In fact, we strongly advise that prospective jailbreakers hoping to jailbreak in the future don’t use these semi-jailbreak tools. Dopamine lead developer Lars Fröder (@opa334dev) seems to be of the same opinion.
On the other hand, if you don’t really care about the risks and you don’t mind potentially losing your ability to jailbreak with Dopamine v2.0 when it launches, then by all means, install and use a semi-jailbreak.
