I would like to crossflash a Sony AD-7191S drive to a Litey 20A3L. I found the flasher and EEPROM utilities at CodeGuys, but can't seem to locate the latest stock 20A3L firmware (bin) that I believe the flasher needs. Does anyone know where I can find it? I haven't crossflashed before, so if I'm on the wrong track I'd appreciate any advice. Thanks in advance!
