## Information This is the official repo for the palera1n project, a jailbreak for arm64 devices on iOS 15.0+ - Loader application used in palera1n can be found [here](https://github.com/palera1n/loader). - palera1ns jbinit can be found [here](https://github.com/palera1n/jbinit). - palera1ns custom PongoOS can be found [here](https://github.com/palera1n/pongoos). Website & credits can be found at https://palera.in (scroll down for credits). ## 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.
