Ultimate UHD Drives Flashing Guide Updated 2026

[ELLEGARDEN777]

Hello guys, I am writing to you because I need your help, wisdom and experience, I bought an external Blu ray reader from the BUFALLO BRUHD-PU3-BK brand. I told you that the device was working well, but suddenly it started reading discs discontinuously, when In the end, the LED stays red and the unit icon no longer appears on my PC. I have tried to solve it in every possible way but I have not been successful. I don't know if the device broke due to hardware failure or maybe it was something. with internal software files, I would greatly appreciate your help to solve this problem T_T

What happens if you unplug your drive, let it power down, wait for a couple minutes, then plug it back in?

Wild guess, this may be worth a shot. Disconnect the drive from USB, clear Not Connected USB devices using Nirsoft USBDeview (little portable app - no install), then reboot and reconnect the drive, see if that may help. You have to run USBDeview with admin rights (right-click USBDeview.exe and Run as administrator), then right click and "Uninstall Selected Device" on Not Connected USB devices. Not Connected USB Devices will be listed at the bottom of the shown USB history.

Hello,

I have just been looking around and noticed that some BluRay drives are capable of being flashed to support 4K Ultra HD Disks. However, I am unsure if mine is compatible and if it is worth flashing or just buying a new drive that supports 4K disks. I am currently only using BluRay disks. However, if I can flash it would save me going out of my way to purchase a new drive.

Information that shows up in MakeMKV -

Drive Information:
Manufacturer: PIONEER
Product: BD-RW BDR-TD05
Revision: 3.00
Firmware Date: 2012-11-14
Bus Encryption flags: 1B
Highest AACS version: 66

LibreDrive Information:
Status: Possible, not yet enabled
Drive platform: Pioneer RS8211
Firmware version: ID74

If you have any insight and are able to assist me that would be great. I do not have high hopes of this working. However, it would be awesome if it did.

Thank you in advance!

That drive was built over three years before the specification for UHD existed, so it is "highly doubtful" it could be modified.

No. Not able to be flashed for UHDs.

Hello!

I've been reading through the forums, and I purchased a drive per the guide.

I've drafted a plan for flashing my Buffalo BRUHD-PU3-BK. I would appreciate any corrections or validation before proceeding, particularly regarding the SDFtool values referenced at the bottom of the post (boot loader and firmware version). I've found the forums extremely helpful overall and really appreciate those who've contributed. Thanks in advance for the advice!

Plan:
1. Install MakeMKV and identify drive:

Code: Select all

Drive Information
OS device name: E:
Manufacturer: BUFFALO
Product: Optical Drive
Revision: BU14
Serial number: MO2N5DA3110
Firmware date: 2121-06-21 13:30
Bus encryption flags: 1F
LibreDrive Information
Status: Possible, not yet enabled
Drive platform: MT1959

2. Download and extract SDFtool Flasher executable, updating for 4K screen per thread.
3. Download and extract firmware files per SDFtool Flasher thread.
4. Configure SDFtool Flasher with the following settings:
- Drive: `{path}: BUFFALO_Optical_Drive_BU14...`
- Drive metadata: MT1959 Platform ✔ | Encrypted Firmware ✔ | Include boot loader (?)
- Firmware: TBD (?)

(?) Seeking Clarity:
* I am unsure whether to include the boot loader per the SDFtool Flasher - UPDATE - 21/12/2021]

The latest version of the SDFtool Flasher has a checkbox option to flash the boot loader with the main firmware to the drive. This is useful for the newer BP50NB40 with SVC: NB52. It's also possible that other newer models may require this option later on. We will all work it out together as we go!!

** I am unsure which firmware to choose based on Re: SDFtool Flasher and Re: BRUHD-PU3-PK BU12 to BU10?

BU40N 1.03-MK is the firmware to flash to first. If you want to flash another after that, such as BU40N 1.00 (for more software compatibility) you can.

1. HL-DT-ST-BD-RE_BU40N-BU12-OM01001-211902230922.bin
2. DE_Buffalo_BRUHD-PU3_BU10 OR DE_LG_BU40N_1.00

There's really no need to ever include the boot loader unless you've royally screwed up a flash.

Thank you @MartyMcNuts. I also went ahead and flashed it to `BU40N 1.03-MK` using the guidance in this post.

Thanks for the help!

Hello

Is it possible to flash this one if the firmware is older than December 2022? Pioneer BDR-212EBK.
What tools and software do i need, if so?

Greetings

I have this older version Pioneer slim drive that I was hoping would work due to older firmware...does it need to be updated to 1.01 or 1.02 to enable LibreDrive...if so, how do I do this as I don't see any Pioneer FW in the "All You Need FW Pack"

Thanks!

hello ,

this has probably been asked already,

is there a good slot-in 9.5mm bluray drive that can do UHD or be made UHD friendly?

Hi All,

I'm a bit new here but I'm trying to flash a drive using my Mac. I thought I had successfully flashed a drive. See text from the terminal session I ran.

After running this operation and opening MakeKKV, it still shows the drive is on Revision 1.02. Does anyone have any idea where I went wrong?

Any help appreciated. I'm using a archon MD-8107X-U3YC-UHD.

Thank you!!!!
