Just yesterday, we broke the news about ra1ncloud, a Fugu15-based jailbreak for arm64e devices running iOS 15.0-15.4.1. While it wasn’t released at the time, that fact appears to have changed overnight.
In a release post shared on /r/jailbreak late last night, GUI developer EmuNew3569 shared that ra1ncloud was officially available on GitHub.
But before you rush to install ra1ncloud, there are some things you should probably know about it first.
The first and foremost comment we have is that the pre-release post emphasized “user friendliness,” and while the ra1ncloud GUI is definitely easier and more polished than Fugu15, we can only describe ra1ncloud as Fugu15 (a developer jailbreak, not an end user jailbreak) with a different wrapper on it.
What do we mean by that? Well… the jailbreak doesn’t really offer anything to users that Fugu15 didn’t already have. For example, the GitHub page notes that ra1ncloud doesn’t support tweak injection and that it probably won’t ever support it. It also says that the jailbreak isn’t intended for “end users,” which once again suggests that this is a developer-focused jailbreak, but with a prettier UI.
To ra1ncloud’s credit, it’s probably a lot more stable and user-friendly than the XinaA15 developer jailbreak.
Some other notes in the GitHub’s FAQ section suggest that the developer doesn’t plan to update the ra1ncloud jailbreak with any improvements and that they’re entirely done tinkering with iOS 15, which may also turn some users away.
From what we can gather, tweak injection wasn’t included because no one has figured out how to implement it yet. If anyone is skilled enough to figure this out, then they’re advised to reach out to @iarchiveml or @rebeldisc on Twitter to discuss.
Because ra1ncloud is Fugu15-based, this means that it’s a semi-untethered perma-signed jailbreak. In other words, the app remains signed on your iPhone forever and needs to be used to re-jailbreak your iPhone after every reboot. You won’t need to re-connect to a computer or re-sign the app ever.
Ra1ncloud is rootless, which means that the OS/root folder isn’t modifiable like it is on full-fledged jailbreaks. The rootless dynamic is likely to be the future of jailbreaking altogether.
The ra1ncloud jailbreak app can be installed on your iPhone a number of different ways, including via TrollStore (the easiest method), Safari (using a method similar to what Linus Henze demonstrated when announcing Fugu15), or via USB connection (with some commands).
As you might come to expect on a modern jailbreak, ra1ncloud uses the Procursus bootstrap and installs Sileo as the package manager by default. Of course, without any tweak injection, you can’t install jailbreak tweaks.
Currently, ra1ncloud has been tested on iPhone XS, iPhone 11, iPhone 12, and iPhone 12 Pro Max, all on iOS 15.4.1. It has also been tested on iPhone 13 running iOS 15.1. Other device and firmware combinations may also work fine, but haven’t been officially tested.
Some kernel panics are known to occur when a ra1ncloud-jailbroken device goes into deep sleep mode or when using Wi-Fi.
We wouldn’t recommend using ra1ncloud unless you’re a developer or an experienced tinkerer who knows how to troubleshoot and fix issues, but if you’re curious about it or want to learn more about how it works, then you can visit the project’s GitHub page to learn more.
