    Nothing is wrong with using the ASUS flasher but why would you want to spread misinformation??? There are people who've had issues with the ASUS flasher and if they're under the BS impression that "oh, I have to use this cause 'protection'" then they're not going to get the solution they need. The flasher has nothing to do with it. At all. As for can I point you to the discussion? No, it's been discussed many times on MakeMKV's forum. What do you think the MK firmware DOES? And why do you think the MK firmware is REQUIRED to downgrade these drives? If the ASUS flasher magically removed the protection, why would I need an MK firmware in the first place? See where the logic there falls apart? Mike put a lot of work into modifying these firmware versions to allow downgrade and cross flashing. But that has nothing to do with the tool. Again, it's the misinformation that irritates me because people are taking that as gospel, running into problems with the ASUS flasher, and not trying the LG flasher that would work for them, because this of this nonsense.

    Great information on this site...I have the LG WH16NS40 NS50 ver1.00 Rips Blu-rays great (around 40min) and just started with UHD (around 1hr 15min) and I notice that with the UHD I get these "work around" errors in mkv but I just restart it and it copies on the second run. I am thinking it could be disc related. Anyway, I read and notice everyone with 1.02v firmware. Is there any reason that this drive should be upgraded to 1.02v or if it aint broke don't fix it.

    Nope. The easiest way is to boot from a Windows PE boot stick and do it from there. You'll find one pre-created on MakeMKV's forum for this purpose. It has all the tools and firmware built in so you just create a USB boot stick, boot from it, and then flash away.

    Thanks for the quick response, could I use the drive on the Mac afterwards again ?

    Yes, definitely. Only needs to be flashed in Windows.

    If it works don't flash it.

    hello seems that latest LG BH16NS55 drives manufactured in 2019 are delivered with firmware 1.04
    Is it still possible to downgrade them to 1.02 ?

    Yes. You need the NS55 1.04 MK firmware. After that you can either leave it or you can downgrade it. That firmware is found on the MakeMKV forum.

    Thank you
    i assume you are talking about libredrive patches

    https://www.makemkv.com/download/mk-firmware-pack-20191206.zip

    it says it restore libredrive feature (i do not know what it is) and Removed firmware downgrade check

    is still possible to use the dosflash method (teddy raspin method in this post) to flash 1.02 ?

    i do not want to use makemkv, but want to use it with anydvdhd (as my previous drive in 1.02) as uhd friendly drive

    DO NOT USE DOSFLASH!

    The MK firmware does not require MakeMKV. It's just that the author builds the firmware that restores UHD friendliness to these drives. Use one of the windows flashers with the MK firmware and you're done.

    Once with 1.04 mk firmware on drive, will it be possible to use the same Windows flasher to get bet back on firmware 1.02 ?

    If you wish. Or you can leave it on 1.04 mk. Either will work.

    Very important hint (y) I think this should be placed on page 1 in this thread. Many people crashed there drives with this tool, because they were not experienced in changing FW.
    Actualy there´s no need to use DOSFLASH anyway since FIRMWARECHANGER MODIFIED came out. Please correct me, if I´m wrong.

    It won't work on these new firmware anyway. The dosflash method only works on older firmware. They disabled the interface that it uses in new firmware.

    Thanks for the hint @SamuriHL (y) So we can all leave as it is - No further danger with DOSFLASH?

    I don't know that I agree with that. If someone were to try they could conceivably screw things up. I just think at this point we need to take dosflash off the table.

    That's right - Everybody is free to use it.

    Hi. I have motherboard with NO IDE support - only ahci and raid. Is there any way to backup orginal firmware using windows?? Also is it safe to flash de or mk firmware without doing backup of orginal??
