    Please don't attempt this. 3.11 removes the ability to downgrade firmware directly. Previously, you had to cross-flash to BW-16D1HT 3.10-MK, then downgrade to 3.01 but often, the drive became stuck on 3.10-MK.

    The easiest and safest way is to directly flash BC-12D2HT 3.11-MK and be done with it as this firmware is UHD friendly. The download link for the latest modifed ASUS flasher + firmware pack is below.

    You're right with your warning and 3.00 was the last official firmware, known as friendly. The 3.01 modified, I attached, will be able to backup UHD.
    I hadn't seen this new modified version.

    Yep, 3.11-MK has been around for a couple of months now.

    I have updated my OP with more information and the latest file/s.

    Very good. (y) I'm with the BH16NS 55 and firmware 3.10-MK. There was no need for me to look for newer firmware packs the last month.

    I have updated the download link in my OP as a new MK firmware pack was just released. It now contains firmware BP60NB10 1.01.

    Hmm... :confused:
    I recently bought this ASUS BW-16D1HT (Firmware 3.10) and read all about flashing and...
    I don't get it!?
    Should I or should I not flash the firmware?
    I'm not into ripping or playing UHD discs, only Blu-ray.
    I will use this drive only for ripping and playing Blu-ray, not burning.
    I read about a "sleep" bug and ripping speed.
    What is the "sleep" bug?
    Only tried one Blu-ray (43.4GB) so far using AnyDVD HD and it took about 30-40 minutes.
    Is that anything I can speed up with a firmware flash?
    Could a faster rip speed add errors to ripped image/folders?
    I don't mind the longer time as long as the copy is perfectly 100% OK.
    Ideas and input is much appreciated!
    Still using Win7 x64

    If you're not doing uhd then leave it alone. None of it applies to bluray.

  10. So I just picked up an LG WH16NS40 svc ns50 that was manufactured in 2019. It came with 1.0.4-01. I've tried both the modified ASUS firmware tool and the modfied H-L one to downgrade to DE_flash_HL-DT-ST_BD-RE_WH16NS40_1.02_NS50 but I get errors.

    With the Asus tool I get "updating failure #4"

    With the H-L tool I get: "Write DRAM NG 05/26/03"

    Try flashing 1.04-mk first. The you can flash 1.02.

  12. Ok. I have the MK firmwares but dont see the 1.0.4 version, just 1.0.3 and 1.0.2. Where can I acquire the 1.0.4?

    ok so I was able to flash 1.0.4 but using but using the WH14NS40-NS50 version and not WH16NS40-NS50.
    I was then able to flash 1.0.2 WH16NS40-NS50 however I'm only getting a 2.6x read speed. Is that normal?

    When ripping UHD, the speed is generally not constant. It will continuously fluctuate between 2x-6x. The fastest "friendly" firmware would be the ASUS BW-16D1HT 3.10-MK which seems to stay in the upper speed range for longer.
  14. Can I flash ASUS BW-16D1HT 3.10-MK to a WH16NS40-NS50?

    You can if you want.
  16. It wasnt a matter of if I wanted to but if it would work or brick the drive if I flashed a different vendor flash on it.

    These drives all share the same chipset so they can be cross flashed just fine.
  18. @SamuriHL and @MartyMcNuts Thanks for your help! Got my 2019 LG working now with ASUS BW-16D1HT 3.10-MK and its a bit faster. It has gone from 2.6.x using the LG 1.0.2 firmware to 5.0x using the Asus firmware!

    Hi All
    I'm new to this forum.
    I have an Asus BW-16D1H-U drive and before knowing this forum i have flashed a wrong firmware for converting in to UHD friendly drive. Unfortunately i don't have the original dumb(which i learned in this forum today).
    Now the drive didn't read any disc like audio cd or bluray.
    When i insert my disc there is no light flashing at all.
    I have attached informations of my drive and the wrongly flashed firmware below.

    Any help would be appreciated.
    I would be happy if i can at least read bluray disc's again.

    This is the wrong firmware i flashed

    Drive information inside the case:
