Thank you, Billy. That’s great!!

Flashing to the BP55EB40-NB50-1.03 MK firmware has now worked perfectly using the recovery process in SDFtool Flasher.

Unfortunately, I can’t use the official LG firmware file you linked, as it contains version 1.01, and it won’t allow me to downgrade. Same ...

Thanks so much!!

I found the BP55EB40-NB50-1.03 firmware in the mk firmware pack but my drive has SVC EB52 not NB50...

I also found an official BP55EB40 1.03 updater on the LG website but only for the SVC EB40 model...

Will these two still work? If so, what would the steps for SDFtool ...

I have an LG BP55EB40 NB52 drive which I previously flashed to BP60NB10 1.02-MK using SDFtool Flasher.

For warranty purposes, I now need to flash it back to the original BP55EB40 firmware, ideally BP55EB40 1.03. Failing that, I would at least like to get it back to BP50NB40 1.03 rather than ...

Thanks so much for these, Marty!! It's really appreciated!! :D

Will the BP50NB40 1.03 firmware work for a BP55EB40 SVC: EB52 as well?


These original flashers only work for that particular model, so no.


Thanks, Marty!! If you ever happen to come into possession of the original BP55 ...

Hi all,

I recently purchased a second Verbatim 43888 as a back-up drive. I was expecting to receive the LG BU40N, and that's exactly what I got.

I already have a 43888 with a Pioneer drive, so I've decided to use the LG as my primary drive (preserving the Pioneer). As I'm just backing up Blu ...

Fixed, download should work now.
