Sony ddu1615 HELP is there a way to change the firmwire revision code

I just flashed my drive with Fys2 firmware. i went to the dell site and found a more advanced firmware but i cannot use it as my drive dosen’t match anymore. can anybody who have the same drive backup the firmwire using ltnFlash and send it to me. the firmwire version should be FDS1.

    Is there a way to change the firmwire revision code?
