Hi anyone know of any firmware ugrade which flashes a DW1620 to a DW1625??
Their is no point you need extra hardware to be able to burn Lightscribe discs which the 1620 does not have and the 1625 does not have the media over speeding options that the 1620 has.
If for whatever reason you still feel the need to flash the 1625 firmware there are .cvt files on the unofficial BenQ firmware page.
You can increase the read speed of the 1625 with mediacode.
Sure, but you can do that with your 1620 anyway so why flash the 1625 firmware ?
