No. The Pioneer flasher is not public. Contact Billycar11

Ok that's what I thought. Thanks for clarifying!

Hi Team,

I bought a new Verbatim 43888 from eBay.
I just unboxed it and see the below details.

What do I need to do here to rip 4k discs?
Thinking of keeping this as a spare after getting one from MartyMcnuts a couple of weeks ago.
Did I get lucky or unlucky here?

It sees a 4k disc (Escape From New York) but won't rip it.

Read and follow the first post in this thread to flash your drive.

I just bought a brand new BU40N (mfd March 2026) that came with 1.05, presumably encrypted.

I reviewed the instructions in the first post many times, intending to follow the explicit instruction "BU40N on any Firmware directly to > BU40N 1.03MK". However, I was getting stuck not being able to find the 1.03 MK file for this drive. I couldn't find it in the MK set I had saved: mk-firmware-pack-20190319 or The all you need firmware pack which is linked in the first post.

Eventually I found a copy in Marty's collection All You Need Firmware Pack (MartyMcNuts). But it turns out the correct file was in The all you need firmware pack all along, it just has a different name:

HL-DT-ST-BD-RE_BU40N-1.03-NM00000-211810241934.bin in The all you need firmware pack is the same as the DE_LG_BU40N_1.03_MK.bin in the All You Need Firmware Pack (MartyMcNuts).



I would suggest either updating the filename in The all you need firmware pack or adding a filename instruction in the post to avoid this confusion.

No not updating the name come on man obviously 1.03 mk is that
That's the official name as the author made it

Maybe I'm just a big dummy.

Between all the various warnings about bricking a drive by using the wrong firmware, I spent a lot of time trying to find "BU40N 1.03MK" using the links and resources in the guide but was unsuccessful in finding a file so labeled.

I just acquired an ASUS SBW-06D2X-U external USB drive. MakeMKV identifies it as follows:

Manufacturer: ASUS
Product: SBW-06D2X-U
Revision: A102
Serial number: [redacted]
Firmware date: 2121-06-28 13:41
Bus encryption flags: 1F
Highest AACS version: 81

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

I've read the first post on this thread, but it is unclear to me which firmware to flash to it. The only ASUS firmware in The all you need firmware pack is for an internal drive, and that first post says not to crossflash between LG and ASUS slim drives. How should I proceed? (My old Windows machine is basically non-responsive, so I'm trying to do this on a Mac. I've downloaded sdf.bin and am comfortable using the command line, just not sure what firmware to use. Any help much appreciated.

It's far easier to say MK than it is NM00.......... so we say MK. This is why I named them MK in my firmware pack.

Thanks, now I've got it working.

Hi all,

Hoping for some guidance before I flash anything, since my drive's starting state doesn't quite match the cases I've found in other threads.

My drive info (from MakeMKV):

Manufacturer: LG
Product: BP50NB40
Revision: A101
Serial number: M60G7F01205
Firmware date: 2116-02-24 11:44
Bus encryption flags: 1F
Highest AACS version: 43

LibreDrive Information
Status: Enabled
Drive platform: MT1959
Firmware type: Original (unpatched)
Firmware version: 0.A101D
DVD all regions: Yes
BD raw data read: Yes
BD raw metadata read: Yes
Unrestricted read speed: Yes

What's working: Standard Blu-ray discs read and rip perfectly.

What's not working: UHD 4K discs don't mount at all — no media detected, drive spins briefly then gives up. Tested on two different movies/discs, so it doesn't seem to be a single bad disc.

My question: Since "Product" still shows as BP50NB40 (not BU40N or BP60NB10), I understand from other threads that this firmware platform can't handle UHD regardless of LibreDrive status. Given my drive already shows "Enabled" natively (not the usual starting point of "Possible, not yet enabled" that most guides assume), which is the correct file/process to cross-flash to BP60NB10 or BU40N?

I found DE_LG_BP60NB10_1.00_MK_HBD.bin in Marty's "All You Need Firmware Pack" and was planning to try a straight WRITE (not RECOVER) with that hybrid file via makemkvcon on macOS (Mac Mini, Apple Silicon) — but wanted to confirm this is correct for an A101 revision specifically before proceeding, since I haven't seen this exact starting state discussed elsewhere.

Thanks in advance for any guidance!

They emailed me and I looked into this further
This drive was fake as the build date was Oct 2025 with svc nb50
If it were real the build date would have been nb52
