This USB exploit works on 7 generations of Apple silicon (A5, A6, A7, A8, A9, A10, A11), including iPhones, iPads, Apple Watches, and Apple TV. There are public implementations of this exploit for all of these chips, but not all of them are supported by ipwndfu. This is the exploit used by the checkra1n jailbreak.
