&gt;You may not need to crack the OS, or even upload a new firmware. You just need to disable the mechanism that wipes the device and delays how many wrong tries you get. So for example, if you can manage to corrupt, or patch the part of the system that does that, then you can try thousands of PINs without worrying about triggering the timer or wipe, and without needing to upload a whole new firmware.<p>I disagree. The pin validation is done within the secure enclave. You can&#x27;t do it outside the secure enclave because the pin is combined with a secret that is burned into the silicon of it. The secure enclave can and will enforce timeouts for repeated failures, as well as refuse to process any pin entries after too many attempts. Disabling the wipes or bypassing the timer won&#x27;t do you any good when you only have a few attempts.<p><a href="https:&#x2F;&#x2F;blog.trailofbits.com&#x2F;2016&#x2F;02&#x2F;17&#x2F;apple-can-comply-with-the-fbi-court-order&#x2F;" rel="nofollow">https:&#x2F;&#x2F;blog.trailofbits.com&#x2F;2016&#x2F;02&#x2F;17&#x2F;apple-can-comply-wit...</a>
