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 May 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.
