In this section, you’ll find the latest iOS 27.2 jailbreak news, updates, tools, and releases.
📰 Doublera1n jailbreak: New iOS 27.2 Jailbreak Creates a Separate Environment on iPhone 11
A new open-source project named doublera1n has introduced an alternative way to run a jailbroken iOS environment on A13-powered Apple devices. Developed by 34306, the project uses the usbliter8 hardware exploit to launch a secondary jailbreak environment while preserving the original iOS System volume.
Unlike conventional dual-boot solutions that require a separate system installation, doublera1n uses an additional data volume alongside the device’s existing iOS installation. This allows users to access a rootless jailbreak environment without replacing the original system files.
The project has attracted attention following a successful demonstration on an iPhone 11 Pro running iOS 27.2.
How Does the doublera1n Jailbreak Work?
doublera1n takes a different approach from traditional iOS jailbreak tools. Instead of modifying the original system installation, it keeps Apple’s sealed System volume intact and creates a separate data partition, known as the second Data volume.
The jailbreak environment uses a patched kernel and iBoot, with the usbliter8 exploit providing access to pwned DFU mode. Once the modified boot process is completed, the device can run the rootless jailbreak using its secondary data environment.
This design also addresses some disadvantages of conventional custom firmware installations, particularly their storage requirements and reboot-related recovery problems.
Users can switch back to the original iOS installation through a normal reboot. However, returning to the jailbroken environment requires connecting the device to the required hardware and repeating the boot process.
doublera1n Compatibility
The developer’s repository currently lists support for iOS 27 through iOS 27.2 on the main operating system.
The project targets A13-based hardware, particularly the iPhone 11 family. However, compatibility across all supported devices has not been established.
The developer has specifically confirmed a successful boot on the following configuration:
- Device: iPhone 11 Pro
- iOS Version: iOS 27.2
- Build Number: 24B119
- Jailbreak Type: Rootless
- Boot Method: usbliter8 / Pwned DFU
The repository also lists the second-generation iPhone SE and iPad 9 among its A13 targets, although iPad 9 support is marked as untested.
Other device and firmware combinations require further testing.

📰Calif Demonstrates Jailbreak Surviving an iOS Update
A new jailbreak demonstration from security research team Calif has attracted attention in the iOS 27.2 jailbreak community. The researchers have shown that an iPhone jailbreak can survive an iOS software update, even with Apple’s Lockdown Mode enabled.
According to a report published by MacRumors on November 3, 2026, Calif demonstrated the technique on an iPhone 18 Pro. The demonstration showed a compromised device receiving an iOS 27.2 update while retaining its jailbroken state afterward.
Jailbreak Survives iOS 27.2 Update
The demonstration highlights an interesting development in iOS security research. Calif showed an attack involving a PDF file delivered through AirDrop. After the user accepted and opened the file, the researchers were able to compromise the device despite Lockdown Mode being enabled.
More importantly, the jailbreak remained active after the device was updated to iOS 27.2.
However, this does not confirm that the same exploit can jailbreak an iPhone that already has iOS 27.2 installed. The initial compromise was demonstrated before the software update, and the exact technical process has not been publicly disclosed.
Calif has indicated that it intends to report the vulnerabilities to Apple rather than release a public jailbreak utility for general users.
