Installing palera1n

For support in English, ask for help on the r/Jailbreak Discord Server.

palera1n is a work-in-progress jailbreak that patches the kernel so you can use Sileo and install tweaks. Currently, palera1n is compatible with A11 (iPhone X) and earlier devices on iOS 15.0 to 16.3.1, with some major caveats.

On A11 devices, you must disable your passcode and will not be able to use your passcode, or other SEP functionality, until you boot into a stock iOS state. SEP functionality includes things such as a passcode, Face ID/Touch ID, and Apple Pay.

Additionally, if your device is an A11 device on iOS 16 and you've set a passcode before, you will need to erase all content and settings in order to be able to jailbreak.

WARNING

This version of palera1n is currently in beta. If you're not comfortable with using beta software, you can follow Installing palera1n (Legacy) instead.

WARNING

If you are using an old version of palera1n that was tethered, you'll need to remove palera1n before continuing.

TIP

If you are using Windows, proceed to Using palen1x.

Please select your operating system:

macOS

Installing palera1n

1. Open a terminal window and cd to the directory that palera1n was downloaded to.
2. Run sudo mkdir /usr/local/bin
   • If you get a message saying mkdir: /usr/local/bin: File exists, this is safe to ignore.
3. Run sudo mv ./palera1n-macos-universal /usr/local/bin/palera1n
   • Replace ./palera1n-macos-universal with whatever version you downloaded
4. Run sudo xattr -c /usr/local/bin/palera1n
5. Run sudo chmod +x /usr/local/bin/palera1n

Running palera1n

WARNING

If you are using a USB-C to Lightning cable to do this process, you may run into issues entering into DFU mode

If you do have issues, get a USB-A to Lightning cable and, if necessary, also get a USB-C to USB-A adapter.

TIP

If you're using an Apple Silicon Mac and using a USB-C port to plug your cable/adapter into, you'll need to unplug and replug the device after Checkmate! appears in the logs.

1. Run palera1n <insert arguments here>
   • 16GB devices should use palera1n -B -f - note that you'll need to have 2-3GB of storage space free.
   • Devices with more than 2-3GB of storage space free but with less than 10-15GB of storage space free also can use palera1n -B -f, but only if they're on iOS 15.
   • Devices which have iOS 16 or have more than 10-15GB of storage space free should use palera1n -c -f
   • Make sure your device is plugged in when entering this command

WARNING

If your device is either:

• On iOS 15 and does not have at least 2-3GB of storage space free
• On iOS 16 and does not have at least 10-15GB of storage space free

You won't be able to continue following this guide.

If you cannot free up enough storage to follow this, you can alternatively use the tethered option of legacy palera1n by following Installing palera1n (Legacy) instead.

2. When ready, press Enter and follow the on screen instructions to enter DFU mode.

Your device should begin to create the FakeFS or BindFS (depending on which command you ran).

3. Once your device is done creating the FakeFS or BindFS, run palera1n -f

TIP

A9(X) and earlier devices have an issue where they will get stuck midway through this process in pongoOS. To work around this issue, you'll need to do the following:

1. In the terminal window, press Control + C on your keyboard
2. Rerun the command that you just ran

You'll need to do this every time you rejailbreak your device as well.

Linux

DANGER

If you are trying to use a Virtual Machine software of some sort from Windows (e.g. Virtualbox, VMWare, Windows Subsystem for Linux, etc) you will not succeed with following this guide.

WARNING

If you are using a computer with an AMD Ryzen CPU, you will likely run into issues. If you do run into issues, you should use a Mac or a computer with an Intel CPU to follow this guide.
