The problem is that those affected phones could still have had compromised fingerprint sensors.<p>... which wouldn&#x27;t be used after the phone determines it&#x27;s an aftermarket part. Equally well the attacker may have installed a malicious piece of brick inside.<p>&gt; Apple did the right thing in protecting people from this<p>Sure, they protected users from using phone with replaced home button and disabled fingerprint scanner by bricking the phone completely.<p>Hard to tell in what proportions malice and&#x2F;or stupidity were involved in this case, but either way it wasn&#x27;t &quot;doing the right thing&quot;.
