Have tried battery, speedo, voice methods etc but none of those screens show hardware id.

Press on battery icon (main menu page) for about 5 seconds.
Press "Next" for 3 times , you see red color page , just press right lower coner for 5 times , you see "Next" - kepp pressing then you see inventory page.

Press "Start Test" then press "More".
Now you get inventory page.
Notice the first line - Boot BLK Bxxxx-00
xxxx = hwid.
