This is use of the word "bricked" which is a novel inverse of my normal understanding. To me a "bricked" device has been corrupted in core boot so bad, even JTAG may not get it back. It's the unusable state.

"rooted" is the more normal description of 'I got to install some code on it which the original vendor did not want me to be able to install' surely?

Or has geek english moved on to invert the greybeard meaning of "bricked" ?
