BU4ON or funny firmware implant

Hi all,

I bought this driver off Taobao (Chinese e-commerce site) and have been using it for my normal blu-ray rips successfully.

I have some 4Ks that I wanted to try out, but the driver couldn't get pass the encryptions, so I believe it needs flashing and all.

Just curious if I actually got a BU4ON or its actually another driver with a firmware titled BU4ON inside, whether i should flash and risk a brick.

Below is the makeMKV details but what made me have this thought was that the back of the driver says the model is ECD819-Y. Honestly everything seems dodgy so I don't really know what to trust from this product. They could've used another case or something for all I know hahahaha
Drive Information
OS device name: \Device\CdRom0
Current profile: BD-ROM

Revision: A102
Serial number: M83J4MF4119
Firmware date: 2117-12-01 17:08

Not sure if its a cable issue, because there is also no liner for Libredrive and using the SDFtool flasher says MTI1959 platform is not available (needs direct SATA connection to detect?).

I'll probably just get a 4K ready ripper if this situation is too complicated, thanks and much appreciated!

Probably the case is preventing flashing

It probably is a bu40n

But it's 100% not a pioneer so annoying that they do this
