LG BP55EB40 v1.20 - Cannot flash as it's not MT1959?

[Parallax Abstraction]

Hey all.

I just acquired a new LG BP55EB40 Svc EB52 that I wanted to flash with LibreDrive. I followed the process in the first post (including installing MakeMKV 1.18.4 instead of 2.0) but SDFTool Flasher 1.3.6 is saying this drive can't be flashed because it's not an MT1959 platform device. I'm a bit confused as it is an EB52 SVC Code drive but I also noticed it shows as Revision 1.20 in MakeMKV and it was also manufactured in May of 2026 so I'm wondering if this is a new variant that suddenly can't be flashed. I hope not. I've done some looking around and can't find anything about this drive revision at all really, much less it being compatible or not with LibreDrive.

Here's the drive info:

OS device name: F:
Manufacturer: HL-DT-ST
Product: BD-RE BP55EB40
Revision: 1.20
Serial number: <Redacted>
Bus encryption flags: 1B

Anyone seen this? Thanks!
