Warnings

We are NOT responsible for any data loss, or the result of a device being bricked. The user of this program accepts responsibility should something happen to their device. While nothing should happen, jailbreaking has risks in itself.

• If your device is stuck in recovery, please run futurerestore --exit-recovery, or use irecovery -n.

• If you're unable to get out of recovery via these methods please restore with iTunes or Finder.

• palera1n will never work in VirtualBox, VMware or any virtual machine that doesn't support PCI passthrough.

Requirements

• A checkm8 vulnerable iOS device on iOS 15+ (A8 - A11)

  • On A11, you must disable your passcode while in the jailbroken state (on iOS 16, you need to reset your device before proceeding with palera1n).

• USB-A cables are recommended to use, USB-C may have issues with palera1n and getting into DFU mode.

  Technical explanation

  The BootROM will only enter DFU if it detects USB voltage, which boils down to checking whether a certain pin is asserted from the Tristar chip. The Tristar does this based on the cable's accessory ID, and apparently USB-A and USB-C cables have different accessory IDs, and the one of the USB-C cables makes the Tristar not assert the USB voltage pin.

• A Linux or macOS computer

  • AMD CPUs (not AMD Mobile) have an issue [with (likely) their USB controllers] that causes them to have a very low success rate with checkm8. It is not recommended that you use them with palera1n.
    • If your device does not successfully jailbreak, try a computer with an Intel or other CPU

• Apple Silicon Macs with USB-C

  • USB-C port on Apple Silicon Macs may require manual unplugging and replugging of the lightning cable after checkm8 exploit.
  • This problem may be solved by connecting via USB hub, though extensions can vary.

Need help?

Make sure you provide full details on your device, such as:

• iDevice
• iOS Version
• Passcode enabled?
• Logs, if panicked then send latest panic-full log from your iDevice.

Using -VvL would help with debugging.
