Yes. Flash a retail BenQ DW1620 to firmware B7P9 or newer to make it a pro model. Flash an OEM DW1620 drive to G7P9 in order to make it a pro model. You can also crossflash an OEM drive to B7P9 or any B (retail) firmware. If you do a crossflash however, you void your drive's warranty. So think long and hard before doing so. It's up to you.
