• A checkm8 vulnerable iOS device on iOS 15.x or 16.x (A8 - A11)
• Palera1n Loader IPA file, which is available at https://nightly.link/palera1n/loader/workflows/build/main/palera1n.zip
• 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.
• Slive dependencies, available here: https://www.appletech752.com/dependencies.sh

• 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 USBHub.
