Nec 3500 flash froze help help help

i downloaded the firmware update (2.16 to 2.17 - speed hack beta 6 and when i extracted it and run it froze about 80% of the way through the update
now the light on the front of the nec3500 is flashing!!
can i fix this as when i try to run the update again i get the following error message “no devices supported”

if your drive isn’t dead then update the firmware under Safe Mode. i had a similar problem when flashing. the flashing process would hang halfway but the drive flashed without a hitch under safe mode.



Also turn off any antivirus software - actually any program you have running - and do it in safe mode-
