    Hello TeddyRaspin,
    I have also an ASUS BW-16D1HT with Firmware 3.02 from January 2018.
    I was able to read the firmware with the help of your tutorial. Can you modify it for me, please ? I have attached it.
    Thank you in advance.

    Regards
    Michael

    Hi Teddy,
    Many thanks for your quick response and I really do appreciate your expertise ( Sorry about the double posting of my earlier request). I must report that I am still unable to play UHD blu-ray moves because of "Drive's signature of the Dv value seems incorrect (bus encryption) ERROR processing Blu-ray disc, but I am able to play blu-ray movies. Any suggestions?

    You didn't flash someone else's firmware did you? That error means there's something wrong with the drive's firmware. That dv value is unique to each individual drive and is required for proper decryption.

    Hi Ch3vrOn,
    Thanks for your reply. I must confess that I am new to this process and did use a firmware obtained from this thread. Are there any corrective measures I can take? If not I will purchase a new drive.

    That's your problem then. Firmware's posted here are modified for the specific drive of the poster who provided the original firmware dump.

    A poster provides a firmware dump from their drive. That firmware is then modified by teddyRaspin to make it uhd friendly again. The modified firmware works for THAT SPECIFIC drive only, as there's a drive unique signature in it.

    By using someone else's modified firmware you corrupted the drive's firmware of your drive. That's why there's a warning in the original post

    I don't know off it will work, but you could try flashing one of LG's official flashers. Though I doubt it will.

    Hi Teddy,

    I had posted before, but I think it got lost in the newer posts. I have a LG BH16NS55 (attached original file below 1.03). Could you please help downgrade my firmware from 1.03 to 1.02? Also from reading the posts it looks like it is possible to cross-flash to the ASUS which gives a faster read speed. If that is possible, could you also please provide a file/direction on how to do that. Thanks

    Steven
