IMEI is on the bottom of the device. write to support@bsquare.com with the subject bsquare powerhandheld master password. you need to provide the IMEI and the serial no
(both are on the bottom
)
i think it is given individually to the devices
but i can give you the one that worked on mine... got it from the bsquare support..
oh and i don't know what helpscreen you mean but the IMEI should look like this: 351810001034920. usually starting with 35181000 on the bsquare phh's
edit: wow they said HPC device?
i like that
and i hope if you give them this specific subject in the email they will help. the person who helped me was "Mark McGhee".
