    Yes. And guess what ? They CAN be damaged WITH proposed patch as well.

    We can not. End of story.

    It's not always possible but yes, in some case it's possible. Still chances
    are VERY slim: if manufacturer designed such flawed hardware in first place
    chances are REAL high that this problem does not bother them at all so who
    will create such firmware ?
