Hello.
I have just bought a new Hitachi-LG slim portable Blu-ray writer. The drive details are :
SVC Code: EB52
Drive Information
OS device name: D:
Manufacturer: HL-DT-ST
Product: BD-RE BP55EB40
Revision: 1.03
Serial number: SIK
Firmware date: 2121-07-08 16:06
Bus encryption flags: 17
LibreDrive Information
Status: Possible, not yet enabled
Drive platform: MT1959
I would like to ‘update’ the firmware to take advantage of LibreDrive, I have read so many threads on how to achieve this that I have now become rather confused. I would appreciate it if some kind person could check my plan of action to make sure it is correct, before I do it.
Using SDFtool Flasher (v1.3.6) -
1. Flash drive to BP55EB40-NB50-1.03 from MK firmware pack
2. Choose recover drive in tool,
When prompted, select BP55EB40-NB50-1.03 (same file as in step 1)
Then in ‘firmware to write’ select DE_LG_BU40N_1.00 from All you need firmware pack.
Many thanks in advance for your help.
Neal Walker.

I've my first EB52 for flashing here. I thought I do some experimental with it. Just flashed to LG BU40N 1.03MK like the EB40.....and 4K ripping is fine.
Why is the the second step to 1.00 necessary with the EB52?

It's not for Makemkv / AnyDVD / XReveal. Only if you want to use DVDFab / Passkey.

Yeah, the 1.00 compatibility with DVDFab is known. But I thought for the EB52 there is a special reason for this. Or does that only apply to the WP/BP50NB40 with SVC EB52?
