    No he can't, as has been stated a few times now. He no longer modifies firmwares. You either need to use the guide, out hope someone else will do it for you.

    Well I've enough time, I don't have to work.
    It hurts myself denying help to other person who's probably totally lost in technical issues, when I can.
    It's probably also to feel "needed", I tried not to answer any request, but couldn't resist.

    But I'm pretty sure if I'd get dozens help request all the time and you had helped them for free, I'd feel stressed and utilized, too.

    Mattering the uploads, I'll delete those, or have them deleted no problem.
    If the people, I uploaded the firmware don't check the forum regulary it can't be so important.
    OK last help dump was just around 18 h ago ;)
    If he doesn respond in a week I'll delete it. Maybe on vacation for now, or got frustrated cause didn't get help at once, and couldn't help himself for now.

    A reason was that I wanted s.o. to test if his WH16NS60->BH16NS55 with your hexrange and with "dd" hexediting method works with UHD ripping.
    (But afaik you tested UHD ripping already succesfully with WH16NS60->BH16NS55 via the hexeditor-method.)
    The negative side effect is, that more and more people think they can always come, just not to spend a few hours/max a couple of days themselves for making firmware backups +modding.

    Some people used the EEPROM data mover method for modding, also for official WH16NS60 UHD drive <=but here it gives different/strange/unusual result, some report here UHD to not work with some specific ripping software, but with a competitive copy software.

    So I'd expect, it's because it was not done with the other hexrange from Teddy's navigating UHD official/real drive-to-UHD-friedly drive conversion, but not sure.

    Yes. Sry I know you're right. It's frustrating to see, that quite some few people are just too foul to read your guide.

    Maybe there are some that have just too few basic knowledge, have too few trust in themselves, and don't want to send back a bricked device in case.
    There are also many that profit from your guideline, some of them perhaps not mentioning it in the forum.

    And some people brick their device. But if they can't follow your instructions and they are too impatient, I wouldn't have bad conscience about it :)
    Then they'll have to wait a few months, maybe tourist will have an emergency rescue firmware in some time from other unit, working.
    The bad thing is those people will perhaps RMA it, and it's known some online shops resell those devices without testing and repairing from manufacturer.

    I'm not really the cleverest person, if even I can follow your tutorial, then most others also can.

    I am really new to the UHD ripping, I got a LG BE16NU50 and its have firmware v1.02, so I try to downgrade it to v1.01. I made a dump by dosflash, follow the instructions in this page to make a new firmware from a untouch v1.01, and I flash it again with success. The drive show v1.01 in anydvd, and UHD disk ( plant earth II )show up in the file explorer. But when I try to rip it to ISO or file, it will have read error in the middle of the process, and make it not possible to make a iso or copy the folder of the UHD, when I try to play it directly form the disc, it will skipping frame and not reading well too. I try to rip a Blu-ray disc and everything work fine.
    I am doing anything wrong in the flashing process? Someone can help me to check if my firmware have anything wrong? I will try with another UHD disc, just want someone to make sure my firmware is good to go, thanks a lot.

    Hi Teddy,

    I finally got access to an old PC and was able to download the firmware.
    Could you please modify the firmware (BH16NS55) here?

    many, many thx in advance,

    If you download the requiered flash tools, a clean 1.02 FW is included. ( As far as i know )
    Look at the atached file form the german forum.

    I completed the steps to dump the firmware using DOS method. I am not comfortable with hex editing so I prefer to use the automatic method of importing data. I open EEPROM Data Mover, select my dumped file, then clean NS 50 compatible firmwares.7z file noted in first post, and get an error "Incorrect file size". Anyone have any ideas as to what Im doing wrong?

    First you have to extract the clean bin-firmwares from the 7z with WinRAR, 7Zip, etc.
    Then at step 2. of the EEPROM Data Mover select the clean firmware you want.

    Thank you for the reply, Terramex. Process completed, I now own a WH16NS40 with 1.02 firmware!

    Hi all,

    I only have laptops (no desktop) and connect to the Asus BC-12D2HT drive (running, unfortunately 3.01) via USB3. Are there any options in my case or must you actually have a SATA connection?
    I have tried DOSFLASH booted via USB-stick and it reports no ATAPI devices, and flasher.exe finds the drive Ok but will not read from it or flash it.

    Thanks very much TeddyRaspin. I was able to flash my LG.

    If only something could be done about the crippling DRM in PowerDVD as well.. The stupid requirement to prevent mouse operations during playback somehow means I can't even operate PDVD's own menus. Wow. One of many problems of course. Anyway, thanks! :)

    No mouse operations has nothing to do with drm. That's just how the disc was authored. You don't have a mouse with standalone players do you? In most cases discs are played on a standalone player, and those don't have a mouse

    Hmm. Every single DVD I've ever tried supported the mouse just fine. Not a single BD I've ever tried supported the mouse. If this was up to the authors all along, I'd expect some randomness. Regardless, trying to play Jason Bourne UHD with PDVD 18 Ultra (latest), I couldn't even click any of the buttons in the "Mouse is not supported... blah, OK, Cancel" dialog, or any other button/icon in PDVD for that matter (except for the timeline..). If I lucked out and the dialog got the keyboard focus, I could dismiss, but not always.

    Oh well, the lack of support for Nvidia (etc) cards caused me even worse problems. I'm thinking I'll park the whole thing until the next major development.

    Perhaps, but you're comparing 2 completely different disc types. The discs are different, the file structure is different, the authoring of them is different.

    Like buying a Ford stationwagon and expecting it to go 300mph like a Maserati or something because hey, they both have 4 wheels and a steering wheel. You can't do that either, one's a city car, the other's a sportscar.

    So it seems that if you have a laptop and connect to the drive via USB instead of SATA, you're basically out of luck, correct?

    do I have to unplug my other sata device (ssd) before I boot from usb-stick and run dosflash?

    according to other posts here in the forum you'll have to open it and unplug the sata to usb adapter then connect it directly via sata, but it should work.

    I bought a BW-16D1HT with F/W 1.01. must i upgrade to 3.02 and then downgrade to 3.01 or can i modify this F/W direct?

    If you want to use this drive for normal BD reading, you'll have to do nothing. UHD reading will not work , because the FW/drive is too old. 1.01 should be a drive that's about 4 years old and known as NS40.
    No chance for UHD reading with this drive :(
