Well, it would have to wipe the keys to update the firmware.  Alternatively the update process could ask for the password&#x2F;passcode.<p>I agree with you, but even if you install something open source you&#x27;re still trusting the hardware, so at the moment there&#x27;s basically no practical method of not trusting any hardware vendor at all.  Obviously when you get all your hardware and software from the same vendor then it makes a move on the government&#x27;s behalf much more practical for them.
