Maybe I missed this in the article, but does anyone know if this feature can be turned off? Or if it's enabled by default?

What happens in the scenario of a consumer having an old iOS device sitting around, they forget the passcode, but now can't reset it using iTunes?

As far as I understand, there's still the hardware key combination to put the device into DFU mode. In that mode it can still be connected to and a new firmware can be written, but no access to the data is possible.

So in order to un-brick an old device sitting around, you put it into DFU mode (the key combination varies from device to device) and restore it that way.

Of course you don't ever get your data back, but that's totally the expected behaviour.

Do you have any source for that information? I am very interested in that as well but couldn't find any information regarding that so far.

I have always thought (though without any source) that they re-flashed the iPhone by putting it into the DFU mode (and tricking the iPhone bootloader into accepting their key) and then just brute force the key.

That makes sense that DFU would still work, since that would let the data continue to be protected and wiped.

The article mentions the ability to disable this feature on "Managed phones" (presumably through and apple configuration profile).

To answer your scenario though, you can always reboot a "locked-down" iPhone into Recovery mode or DFU mode and wipe the device without being able to recover the data.

I’m guessing you would have to restore the device.
