Hello, shot in the dark here as this was a pretty cheap external I bought for my blu rays but after it popped up that it had the BDR-UDO3 I figured I might as well see if it's UHD compatible. Thanks in advance!

Hi Coopervid, could you please check my drive for UHD flashing and PM me the tool/firmware? Thanks!

Upon opening to inspect:

Pioneer BDR-UD03TBD

will this tool of yours help me to pair the actual disc drive to it's proper glory?

Now what does Makemkv report? BP55EB40 -then it's an LG. But the sticker says UD03? Then the sticker is wrong and faked.

Yeah, so the drive reports as BP55EB40, scammed on ebay but got refund. I'm figuring if I can flash it wth the BDR-UD03TBD firmware it should operate.

This isn't my area of expertise

Sorry you are confused. This is a LG drive that can be flashed with a LG flasher, Pioneer drives require a completely different flasher.

Oh, as it was sold as LG, but contains a Pioneer, I hoped the pioneer firmware would solve.

Sorry buddy! The label doesn't count. What counts is what Makemkv is reporting.

Hi again Coopervid,

Thanks for your patience. I think there's an unusual edge case here that may explain the discrepancy.

This thread from last week appears to document essentially the same situation:

viewtopic.php?t=42497

That drive also reported to MakeMKV as HL-DT-ST BP55EB40 revision 1.00, and SDFTool reported MT1959 Platform: NO. After opening it, the mechanism was identified as a Pioneer BDR-UD03TBD HW/FW 1.00, and MartyMcNuts identified it as Pioneer/RS8511 hardware.

Mine likewise reports BP55EB40 1.00 in MakeMKV, SDFTool says MT1959 Platform: NO, but the physical mechanism is labelled Pioneer BDR-UD03TBD HW/FW 1.00.

So I'm reluctant to try LG firmware on it. Could this be the same unusual configuration as that other drive?
