How does this violate the rules? He's already signed a waiver to his 4th amendment rights, so no court order is needed - he's essentially given them full control over his own property, including his phone (which I presume would include accessing the data via adb instead of the phone screen).

Because then the phone is no longer in the original state as when the defendant turned it over, and the FBI cannot prove it did not alter the contents of the phone (as images cannot be made while the phone is locked).

Even with the lock, how can they prove that? If they're able to get information off of it, they're able to modify it....
