Generally asked:

Are there any differences between

- BDR-UD03
- BDR-UD03B
- BDR-UD03TBD

?

Are the B and TBD flashable to BDR-UD04 like the BDR-UD03 when the firmware is older then 12/2022?
MakeMKV information not available, but perhaps there are any empirical values?

I could get one of ...

It is already UHD, at least the non-sample one is, it just needs to be approved which requires a firmware dump

To be clear, the non-sample drives are the same drives with a newer update and those are already approved

I have a drive that is apparently a "sample" for a UD04tbd from Pioneer and thus its firmware is lower than the regular UD04tbd which causes the drive to be "possible" in MakeMKV instead of just working.

Can anyone help me with forcing it to dump its firmware as it looks like MakeMKV isn't doing it ...
