The palera1n team officially announced in a post shared to X (formerly Twitter) on Monday that the checkm8 bootrom exploit-based jailbreak tool had been updated to version 2.0.
This update brings initial support for iPadOS 18 on the one checkm8-vulnerable iPad that can actually run it — the iPad 7th generation.
In addition, support for iPadOS 17.6 and potentially higher versions of iPadOS 17 on supported tablets has been added in this update.
More than that, the much-awaited support for tvOS 15 and later on checkm8-vulnerable Apple TVs is also now a part of the palera1n jailbreak.
The full change log for palera1n version 2.0 is rather extensive, and includes all of the following:
Highlighted changes
– iPadOS 18 support
This only supports iPads that have gotten 18, and due to this being extremely new some aspects when jailbreaking are gonna be broken. For example, the settings application has been rewritten on 18 and preferenceloader will need to be updated to work. Additionally, ElleKit safe mode UI’s red top bar is not currently working. You can use TweakSettings in the mean time.
– iPadOS 17.6 (and potentially higher 17 versions) support.
– Apple TV support for tvOS 15.0 and above, shipping checkra1n_memo-based bootstrap.
tvOS 15 – 18.0 will NOT require the use of creating a fakeFS, rather you have the classic jailbreak experience similar to 14 and below.
Apple TV does not have a completed package manager, for now we will ship a package manager that is somewhat working however there’s no guarenteed success when using it. It is recommended you use some sort of command-line tool using APT or with ssh to be able to install packages.
– iBridge (T2) support for 5.0 and above, shipping with only SSH and no bootstrap.
– Fix 17.6b3+ mac_mount top
– Added iPadOS 17 and 18 rootful support
– Fixed creating fakefs on 16 and above
– The loader app is less likely to disappearLoader changes
– Rewritten the majority of the loader application. Now fully supporting tvOS and custom configurations for installations from the app.
– New screen when bootstrapping, this will show you the download speeds and what file its currently downloading.
– New ‘Exit Safemode’ option within the loader to use whenever you’ve booted into safemode with palera1n CLI, this will userspace reboot.Device-side changes
– Rewritten the entirety of the device-side logic when booting up using palera1n, this also includes some new features which you may notice when booting.
– You will now be thrown into recovery mode after using specifying either-Bor-f. This is to reduce wait time when trying to boot the copied filesystem.
– Userspace reboots no longer breaks Xcode debugging on a device that has been prepared for development.
– Basic libroot support for both rootful and rootless, implementedlibroot_get_root_prefixandlibroot_get_jbroot_prefix.
– New alert will appear on your homescreen after using--force-revert, prompting you to reboot the device to finish the process.CLI changes
Due to multiple supported environments such as
appletv-arm64being the only environment supported on tvOS 15.0 and above, the user is now required to specify a jailbreak type within the CLI. That being-l(rootless) or-f(rootful)– New
-T,--telnetdoption to start an unauthenticated, unencrypted telnet shell on all interfaces on port 46. This is insecure and is intended to be a backup. Only use it behind a protected firewall and when you are done, rejailbreak without the option. A warning is issued when you try to use this option.Notes
– The A8 HomePod is not yet considered as supported due to lack of testing. It is internally tvOS though so it might work (but no loader). We may revise this statement when more information is available.
While the meat and potatoes of today’s update is clearly the newfangled support for new firmware on devices that weren’t previously supported, it’s worth noting that there are some caveats.
For example, iPadOS 18 may be problematic for the meantime, as the Settings app has been rewritten in Swift and is therefore incompatible with preferenceloader until it can be updated. This means that preference panes for jailbreak tweaks won’t load, but TweakSettings can be used as a quick fix in the meantime.
Likewise, tvOS 15-18 devices don’t require the use of creating a fakeFS, which means the jailbreak experience resembles that of tvOS 14 and earlier. It’s also worth noting that there isn’t a completed package manager for tvOS just yet. The one that ships currently is barebones, and there’s no mention of whether a full-featured package manger will be coming or not.
If you’re comfortable with the caveats, then you can head over to the project’s GitHub page where you can learn more about and download the palera1n jailbreak tool. You can also visit our step-by-step tutorial to learn more about how to use it.
Please note that palera1n requires use of the Terminal to jailbreak.
