BU4ON or funny firmware implant
Posted: Fri Jun 26, 2026 2:38 pm
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

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

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?).Drive Information
