Dump old BenQ f.w?

Is it possible to dump my old f.w. so I can media code speed edit & then re-flash??? Because I don’t see a Dump button or choice??? Otherwise my f.w. is GSOB & all I see are earlier firmwares. Or is there a later or equal f.w. to GSOB???

There’s no way to dump a firmware from a Nexperia-based BenQ drive. There are plenty of 1640 firmwares (BS*B) that you can use.
