Palera1n Jailbreak

Palera1n is the first public iOS 15.0 - 15.7 semi-tethered checkm8 "jailbreak". This is an early release, and using it on your main iPhone is not recommended. As for now, Palera1n doesn't offer an option to use Cydia tweaks lacking the tweak injection feature.

What is Palera1n?

Palera1n Jailbreak is a script for macOS and Linux allowing you to execute iOS 15.0 - iOS 15.7 checkm8 exploit on compatible iDevices. It boots the device with AMFI patches and requires you to install Pogo by Amy through the TrollStore app to access the Sileo package manager.

It is brought to you by Nebula, the developer behind the appreciated IPA Permasigner terminal app, the first open-source solution to install IPA files without revokes on iOS 14.0 up to iOS 14.8.1, and iOS 15.0 up to iOS 15.4.1 using the CoreTrust bypass discovered by Linus Henze.

Palera1n Jailbreak is a work in progress and the installation process isn't as user-friendly as other jailbreaks. To install the semi-tethered iOS 15 jailbreak it's required to make some preparation first and use a computer. Using this tool is recommended only for advanced users!

Palera1n should work for most devices supported by checkra1n, but it's unstable and can get you into some kind of issues on the way. Use it at your own risk and when necessary run futurerestore --exit-recovery, or use irecovery to exit recovery mode.

checkm8 exploit developed by axi0mX is the main engine behind checkra1n jailbreak. The exciting part about this permanent unpatchable bootrom exploit is potentially ensured lifetime jailbreak ability for A5-A11 devices. It means every future iOS release should be vulnerable.

Palera1n Jailbreak executes all necessary scripts to jailbreak and the Pogo app is used to install Procursus Bootstrap and Sileo. The package manager allows you to manage repositories, view packages, and install "jailbreak" apps on iOS 15 - iOS 15.7.

Sileo is a modern APT Package Manager for iOS 12 and up with a focus on speed and usability. It was designed to provide a real Cydia alternative for jailbroken devices. Sileo officially supports all jailbreaks and can share its sources with Cydia if you're on unc0ver or checkra1n.

It was developed in Swift a modern programming language created by Apple to deliver lightning-fast iOS apps. Therefore Sileo Package Manager works fast on all jailbroken devices.

Amy, the developer behind Pogo, is working on implementing a tweak injection method for Palera1n jailbreak. At present, you can't install Cydia tweaks on jailbroken iOS 15 so even don't try. Instead, you can install apps like Filza, OpenSSH, AppStore++, NewTerm 2, etc.

Pogo is packed with a CoolStar's Sileo 2.4, but Amy is pushing through a private repo also beta releases. The build of Sileo bundled in this is considered beta. If you want more regular updates add the https://beta.anamy.gay repo to access the latest releases of Sileo APT.

Note: Palera1n Jailbreak for iOS 15 is in an early stage and it's recommended for advanced users. If you looking forward to Cydia tweaks they are also not working at this stage.

Palera1n Jailbreak was released as an open-source project under GPL-3.0 license through GitHub Repository. The latest Palera1n release works also on iOS 15.5 up to iOS 15.7 (and maybe iOS 16). The Pogo app can be used with patched AMFI as long as it’s installed with a ramdisk.

Palera1n tethered jailbreak for iOS 15.0 up to iOS 15.3.1

Recently, @mineekdev started working on a new branch of Palera1n jailbreak with the main focus on adding support for tweaks. This version boots the device with AMFI patches. On the first run, it'll boot a ramdisk which dumps your onboard blob, and installs Sileo and Substitute.

Substitute is a tweak injection system that runs on already jailbroken devices. Basically, it is used to run tweaks. Substitute 2.2 is using a newly designed tweak injection system that allows loading a big number of tweaks for ultimate customization with minimal overhead on iOS 15.

On top of that, Palera1n with support for tweaks is a tethered jailbreak for all releases between iOS 15.0 up to iOS 15.3.1. Tethered jailbreak is able to temporarily jailbreak the device during a single boot. To start the device with a patched kernel, it must be "re-jailbroken" with a PC.

Supported devices

All A9-A11 systems on a chip (SoC) are supported by jailbreak. Below you can find the actual list of compatible Palera1n Jailbreak iPhones and iPads. The jailbreak was tested to run and work without bigger issues on iPhone X (GSM),iPhone 8, iPhone 7, and iPhone 6s running iOS 15.

  • A9 - iPhone 6S, iPhone 6S Plus, iPhone SE,iPad (2017) 5th Generation.
  • A9X - iPad Pro (12.9 in.) 1st generation, iPad Pro (9.7 in.).
  • A10 - iPhone 7 and iPhone 7 Plus, iPad (2018, 6th generation),iPad (2019, 7th generation) (iOS 14 not supported).
  • A10X - iPad Pro 10.5" (2017),iPad Pro 12.9" 2nd Gen (2017).
  • A11 - iPhone 8, iPhone 8 Plus, and iPhone X.

How to jailbreak iOS 15

To jailbreak iOS 15 using Palera1n first check if your device is on the supported list. Remember to disable the passcode on A10/A11 devices before proceeding with the jailbreak.

Step 1. Install libimobiledevice on your Linux or Mac through brew. This library is required to connect your iPhone through USB to the computer.

brew install libimobiledevice

or on Linux distribution:

sudo apt install libimobiledevice-utils libusbmuxd-tools

Step 2. Clone the Palera1n repo from GitHub. It is used to exploit iOS firmware and boot the device with AMFI patches. Next cd into this repository.

git clone https://github.com/itsnebulalol/palera1n && cd palera1n

or clone the Palera1n tethered checkm8 jailbreak with installed Sileo and Substitute (tweaks support) on iOS 15.0 - 15.3.1. This is a work in progress and iPhones: X, 8+, 8, 7+, 7, 6s+, 6s, SE; iPods: Touch 7 are supported.

git clone -b tweaks --recursive https://github.com/palera1n/palera1n && cd palera1n

Step 3. Run the Palera1n script to jailbreak your iOS 15 device.

./palera1n.sh

or if you are using the Palera1n tethered checkm8 jailbreak with support for tweaks.

./palera1n.sh --tweaks <your iOS version here>

Step 4. Palera1n will replace the Tips app with Pogo IPA (can be also installed via TrollStore).

Step 5. Access Sileo from your Home Screen.

Note: To install Pogo app make sure your device is in normal mode. You'll have to uicache in the Pogo app every time you will reboot your iPhone.

If you want to start from DFU, run this command.

./palera1n.sh --dfu <your iOS version here>

Possible Issues

Palera1n Jailbreak for iOS 15 - iOS 15.7 is still a work in progress and you can get into some issues while jailbreaking. Here are some discovered solutions for various situations.

  1. "sudo usbmuxd -p -f" should fix most USB issues on Linux and install usbmuxd.
  2. If your device is stuck in recovery, please run futurerestore --exit-recovery, or use irecovery -n.
  3. The Palera1n black screen after verbose issue can be fixed by using an onboard blob. You can dump one using SSHRD Script.
  4. If Pogo didn't install to Tips for some reason, you can install the Pogo IPA using TrollStore.
