How to Flash Asus DRW-1608P3S

I’m trying to flash my Asus DRW-1608P3S drive to pioneer, and having no luck at all, DVRFlash doesn’t seem to be working at all, it gets so far and then says file size is a mis-match, anyone have any ideas what I’m doing wrong?

Ok so I’m getting somewhere, I just can’t find the TDB 111L 8.19 firmware anyone know where I can get it?

DVRFlash cannot work without the correct commandline & files, of course.

cheers, got it all working now
