In the last few days, ala42 and us have successfully tested crossflashing BenQ DW1670 OEM (I/O Magic) to DW1670 retail/Sony DRU-820A and vice versa. The latest MCSE v188.8.131.52 now supports crossflash option for these drives. Many thanks to ala42.
The DW1670 firmware 004 that was used is a “development firmware” for internal testing purpose only.
Here are some screenshots.
