Back in March, Dopamine jailbreak tool and TrollStore perma-signing utility lead developer Lars Fröder, or perhaps better known in this community as @opa334dev, spoke at a cybersecurity conference called Nullcon Goa 2025 to discuss the state of jailbreaking in 2025.
Security searcher and jailbreak developer Lars Fröder (@opa334dev) released an updated version of the Dopamine jailbreak tool on Saturday, officially bringing it up to version 2.4.4.
Developer and security researcher Lars Fröder released an updated build of his popular Dopamine jailbreak tool for certain iOS & iPadOS 15 and 16 devices on Saturday, officially bringing the tool up to version 2.4.3.
Dopamine, the iOS & iPadOS 15-16-esque jailbreak tool developed by Lars Fröder, the same developer behind the TrollStore perma-signing utility, picked up another small update this weekend in the form of version 2.4.2.
Speaking at a cybersecurity conference called Nullcon Goa 2025, Dopamine jailbreak and TrollStore perma-signing utility lead developer Lars Fröder, also more colloquially known around these parts as @opa334dev, took the stage to discuss the state of jailbreaking iPhones and iPads at present time.
This Sunday, February 16th marks the 1-year anniversary since Dopamine jailbreak developer Lars Fröder (@opa334dev) released Dopamine v2 with support for the Kernel File Descriptor (KFD) exploit, which introduced support for up to iOS & iPadOS 16.5 on arm64e A15-A16 devices, iOS & iPadOS 16.5.1 on arm64e A12-A14 devices, and up to iOS & iPadOS 16.6.1 on arm64 devices.
We’ve previously discussed the importance of changing your device’s root password after jailbreaking so that unauthorized individuals can’t exploit the default password to SSH into your handset and make potentially malicious changes unbeknownst to you.
In a rarely seen walk back on Tuesday, iOS security researcher and Dopamine jailbreak lead developer Lars Fröder (@opa334dev) released and then pulled an updated version of the Dopamine jailbreak tool in the form of version 2.3.
Back at the start of September, we showed you an alternative to Lars Fröder’s Dopamine jailbreak called Xinam1ne by iOS developer cypwn. Xinam1ne is a fork of the Dopamine jailbreak, but it’s modified in that it supports both rootful and rootless jailbreak tweaks.
If you have an arm64e device (iPhone XR or newer) on iOS or iPadOS 15.0-16.5.1, then the rootless Dopamine jailbreak will probably be your first choice for jailbreaking. It’s by far the most ubiquitous jailbreak for those device and firmware options available.
Lars Fröder (@opa334dev), a security researcher with Cellebrite Labs who is perhaps best known for his work on the Dopamine jailbreak and the TrollStore perma-signing utility for the iPhone and iPad, has regularly given speeches and attending security research conventions throughout the year, including GeekCon and Zer0con.
It looks like it isn’t just the palera1n jailbreak tool getting updates this weekend. A few hours after our announcement post about palera1n v2.0.1 being released, Dopamine jailbreak project lead developer Lars Fröder shared that Dopamine version 2.2.2 had been officially released.
