Stay up-to-date with the latest news and releases of checkra1n, an unpatchable semi-tethered jailbreak based on the checkm8 powerful bootrom exploit supporting A7-A11 devices on iOS and iPadOS 12.0 and higher.
If you still use a jailbreak that utilizes the Elucubratus bootstrap, such as checkra1n or unc0ver, then you may have recently noticed an update for Cydia Installer awaiting your attention.
In April, there were conflicting reports concerning whether the upcoming iOS 17 software update would drop support for the aging iPhone X, 8, and 8 Plus or not. Following the WWDC 2023 keynote, Apple confirmed the company’s decision to ditch those devices in a press release.

Just a couple of days ago, we told you all about a then upcoming jailbreak tweak dubbed Checkl0ck by iOS developer FoxfortMobile intended to enable biometric authentication on A11 chip-equipped handsets that had been jailbroken with checkra1n.
If you’re using checkra1n to jailbreak an A11-equipped handset with iOS or iPadOS 14, then you can’t have a native passcode or use biometric authentication methods like Face ID or Touch ID.
Released just over two years ago, the checkra1n jailbreak has proven to be particularly resilient because of the hardware-based checkm8 bootrom exploit that powers it. The checkm8 exploit targets A7-A11 devices (up to and including the iPhone X), and due to being hardware-based, Apple can’t patch it for those devices already in circulation.
A fuzzy image circulating on jailbreak-oriented subreddits these past couple of weeks has received a lot of attention in the jailbreak community as of late, as it appears to depict iOS hacker and checkra1n team member @siguza commenting in a Discord channel about iOS & iPadOS 15 and the state of the checkra1n jailbreak.
One of the more substantial caveats that plagues jailbreaking an A11 chip-equipped handset running iOS 14 via checkra1n is that you can’t use a passcode. Affected devices include the iPhone 8, iPhone 8 Plus, and even the coveted iPhone X. But perhaps not anymore…
Checkra1n is one of the best ways to jailbreak an iPhone or iPad if you have a compatible device (A7-A11) because it utilizes an un-patchable hardware-based bootrom exploit known as checkm8. Perhaps the only notable caveat to checkra1n is that it’s a semi-tethered jailbreak, which means that you need a computer to return to a jailbroken state if you reboot your device for any reason.
Thanks to the checkm8 bootrom exploit that powers it, the checkra1n jailbreak has earned a reputation for its resilience. No mere software update can patch this exploit, and so susceptible devices (those equipped with A7-A11 chips) should effectively be jailbreakable for life...
Just a couple of weeks ago, the checkra1n team updated the checkra1n jailbreak tool to version 0.12.3 with official support for iOS & iPadOS 14.5 along with a bevy of other miscellaneous improvements.
Sam Bingner has launched an updated version of the Substitute tweak injection method this evening, officially bringing the package up to version 2.0.12.
Substitute is used by default on the unc0ver jailbreak when installing tweaks and add-ons and can be installed manually by the end user on the checkra1n jailbreak if Cydia Substrate isn’t already being used. But regardless of which jailbreak you use, this is an update you probably won’t want to miss.
