Ultimate UHD Drives Flashing Guide Updated 2025

[Billycar11]

I'm pretty new to all of this and having an issue with the firmwear.

I figure I need to get the exact firmwear revision but I cant see to find mine anywhere.

I am using a LG BP60NB10 revision 1.01. In the guide and elsewhere I can see versions 1.00 and 1.02 but not 1.01 to download.

Does anyone have access to that for me to use to flash my drive?

Thanks!

you dont need it thats why it says on any fw

Thanks I appreciate the help! I'm a little stressed about bricking the drive, pretty hard to find cheap.

so am I right in thinking I can flash it safely with: "HL-DT-ST-BD-RE_BP60NB10-1.02-NM00800-212005070935.bin"?

I really do appreciate the help!

Hello

Couple weeks ago I tried to flash a Buffalo BRXL-PUS6U3B-US, I confirmed it had the LG core (if I recall correctly - either way I confirmed it was one that could be upgraded. I followed the instructions here and it looked like it was successful.
In the end though nothing happened and the firmware stayed the same. Drive still works no problem.

I wonder why it didn't work, any help would be appreciated.

Probably didn't do enc or did to low of a fe version first email me or Marty if you want an automated flasher that does it all for you

Thanks, I think you are right, I don't exactly recall, but I don't think I did the enc command.

How do I determine the firmware version it has?
Drive Information
Manufacturer: BUFFALO
Product: Optical Drive
Revision: BN14
Serial number: MOBMC6A5827
Firmware date: 2121-06-21 13:33
Bus encryption flags: 1F
Highest AACS version: 68

LibreDrive Information
Status: Possible, not yet enabled
Drive platform: MT1959

I think I can manage the upgrade; therefore, I will let you know.

Hi. might have been missed in my last post
I was just curious how do I see what the current version of the firmware is? Doesn't seem clear from the makrmkv info.

Thank you in advance

Hi,

I hope this message finds you well.
Unfortunately, I mistakenly flashed my **ASUS BW‑16D1HT drive to firmware 3.10MK, thinking it would enable UHD compatibility. Now it fails with 0x82052400 when I try to flash via SATA.

I understand from the community (e.g. your guide in the "Ultimate UHD Drives Flashing Guide") that I actually need to downgrade to firmware 3.02 to regain LibreDrive support.

Could you please assist me with:

1. A compatible UART-Flasher tool (flasher_uart.exe or devrecovery_uart.exe)


2. Advice on downgrading via UART (steps or timing)



I’m prepared to use my DSD Tech SH‑U09C adapter and follow the correct wiring and terminal steps.

Thank you so much for your help—this is purely for personal backup of UHD discs I own.

Best regards,
Michael

Yeah, you've only done half the job. You need to do the cross-flash part now. Use the recovery method of SDFtool Flasher.

I tried that but must have missed something, I've hired Billy above, so I guess he'll come to my rescue with an e-mail soon.
