NathanLR fork of Serotonin semi-jailbreak goes partially open source

Just last week, we told you about a fork of the Serotonin semi-jailbreak called NathanLR by iOS developer Nathan (@dedbeddedbed) that improves compatibility with rootless-oriented jailbreak tweaks and uses a more reliable exploit — the same one used by TrollInstallerX.

NathanLR semi-jailbreak goes partially open source.

NathanLR is still a semi-jailbreak by definition, so it lacks many of the telltale characteristics of a full-fledged jailbreak like Dopamine. Still, it’s possible to use package manager apps like Sileo and inject jailbreak tweak code into various system processes.

Today, we are excited to share that a sizable part of NathanLR is now open source on the developer’s GitHub page per an announcement shared to social media platform X (formerly Twitter) early Tuesday morning.

We say sizable because the entire project is not open source just yet. As noted in the X post, the hooks are not yet open source, which should change at a future date.

While NathanLR is a newer project with a much smaller following than the now well-established Serotonin semi-jailbreak, we do think that the benefits merit attention.

NathanLR supports rootless jailbreak tweak injection on firmware newer than what the Dopamine v2 jailbreak can run on, specifically, iOS & iPadOS 16.5.1-16.6.1. Since the Serotonin semi-jailbreak has compatibility issues with these tweaks without running conversion software for them, NathanLR promises to be more user-friendly.

It’s worth noting that NathanLR is still in its developmental stages and should be considered a beta project at this time. That said, we recommend that those looking forward to trying it out continue waiting until the bugs get ironed out.

If you’re interested in learning more about NathanLR, then you can head over to the project’s GitHub page to find out everything you need to know. Currently, we only recommend it to those knowledgable enough to know exactly what they are doing.

Are you happy to see yet another high-profile project going open source? Let us know your thoughts in the comments section down below.
