100% Firmware Downgrade for ASUS BW-16D1HT and LG BH16NS55

[FrankM]

Thank you very much @TeddyRaspin and @giomania for your awesome work!

Just the other day I've downgraded the firmware of an asus BW-16D1HT from 3.03 to 3.02 and
now it can rip UHD disks!

I just have one problem and I was hoping someone could help me out, I've (naturally) used and old pc
for the downgrade, but now I'd really love to use the (now uhd-friendly) drive with my desktop computer
which unfortunately does not have a sata port available and I'd want to use it over usb

I've then bought a sata-to-usb enclosure for the drive and it all works very well, unfortunately
sometimes when ripping UHDs the drive stops mid-ripping and ejects the disk.

I'm afraid that it is a power supply related issue, that's because I've found out that the enclosure supplies
2 amps while a standard sata connection normally supplies 3 amps, and so maybe the drive sometimes is unable
to handle the load of work and so ejects the disk

It is very annoying and I'd really really want to solve the problem (even by buying a new enclosure and selling
away the current one)

What do you think? Did anyone have experienced the same issue?
So far online I've only found enclosures which supply 2 amps, do you know of any 3-amps ones?

thanks

Hi TeddyRaspin,

Do you still do the custom bin modifications for the LG BH16NS55 1.03 firmware?

Was following your instructions (or, maybe not, as it seems!:) ) and downloaded my 1.03 firmware fine and then did a 1.02 push based on the firmware I found in one of the zip files here.

...only to realise that's like a 'template' and it needs my specific details from *my* 1.03 at the hex refs you list. Oops.

I'm not sure if you're still around for it, but is it possible for me to send you my 1.03 bin as a zip and for you to work your magic?

[eyesawme]

Sorry TeddyRaspin - i did it!! Thanks to your instructions and actually READING them

Followed your exact details on the hex refs and extracted my 103 firmware refs and transplanted them into the generic/template 102 firmware, re-flashed and presto.

Apologies for not following what clearly does work. Thanks mate!!

Upload your 1.03 file here and one of us will take a look at it for you.

Success - WH16NS40 1.03 to 1.02 using the DOS method.

As noted in the instructions, it took several successive invocations of DOSFLASH for it to find the drive. Did the dump/reflash on a Dell T610 Plus thin client using a SATA extension cable. Had to remove the factory SATA flash module and use its connector for DOSFLASH to work -- it would never see the drive using the secondary SATA connector. Booted from a USB drive into FreeDOS for dump/reflash. Made the required edits on a Mac using Hex Fiend (the partition visible to the Mac shows up as C: in FreeDOS). After flashing the edited firmware drive shows up as v1.02 in BIOS.

Have since successfully ripped The Revenant and Blade Runner 2049 on Mac OS using MakeMKV v1.12.3. And both are properly detected by Plex and play back in 4K HDR on my TV via a Roku stick connected over wireless. So thanks for the method, worked great for me.

Hi I hope I have done the first part correct. The flash is from a LG BH16NS55 1.03

Attached is a LG BH16NS55 1.02 Firmware created with the EEPROM Data Mover. I've also attached the ASUS 3.02 firmware updater if you want to cross-flash your drive.

Hi thanks. Just wondering is there any advantage to flashing the Asus over the lg firmware

I've been reading on this forum & other forums.
I want to crossflash a LG WH16NS60 (SVC code NS60) to an Asus BW-16D1HT.

I have used the DosFlash (outside Windows) & Hex edit method successfully on a LG WH16NS60 & a LG BH16NS55 to v. 1.02.
Both (SVC code NS50) so the method is familiar to me.

One thing I need to know is about the hex editing.
I have read this (on another forum):
Hex edit these sections:
0x1E0000 to 0x1E84FF
0x1E9000 to 0x1EBFFF
0x1F0000 to the end

TeddyRaspin's original guide uses these:
0x1E0000 to 0x1E84FF
0x1E9000 to the end

Which is the correct one to use ?

Is this the best Asus BW-16D1HT v. 3.02 to use ?

Any other instructions for this will be appreciated.

Thanks Marty the firmware has been successful and I can now see uhd discs again

It can read a bit faster

[MartyMcNuts]

@Matt92,

Your welcome.

The ASUS is a little faster. That's about all really. I have 2 LG BH16NS55 drives, one with firmware 1.02 and the other cross-flashed to ASUS 3.02. The LG is the one I use the most as I have never had any read issues so far. I have ripped about 70-80 UHD's and have never even had to clean a disc! I keep the ASUS as a backup drive for if/when I need it.

Also, I forgot to attach the ASUS firmware for you. In order to use the ASUS 3.02 firmware updater, you need to cross-flash to ASUS 3.01 first. Here it is.

UPDATE:

Even better!!! I found a clean ASUS BW-16D1HT 3.02 firmware, so I have created a ASUS 3.02 for you.

both will work but i have used TeddyRaspin's

Thanks for answering Billycar11.
I should have searched this forum more throughly.
TeddyRaspin also posted the hex edit I found on the other forum.
That poster probably ripped it off from TeddyRaspin.

I'll probably give what I have in mind a try next weekend.

I found this advice on another forum & I would like some opinions on it.

The best flash is to use LGWH60NS40 ROM v1.02, or ASUS 16D1HT v3.02 or LGWH60NS60 v1.00 as the base for UHD "friendly" depends on which drive you have, then replace the 0x001E9000 to the end (the section for the burning strategy) with ASUS 16D1HT v3.03's 0x001E9000 to the end (ASUS has the best burning strategy .Of course and importantly, replace with the dumped 0x001E8000 to 0x001E84FF (unique to each individual drive).

Especially the part about using the ASUS v3.03 firmware 0x001E9000 to the end.

Is this how it works & is this the better burning engine ?
