BU50N Firmware Help

#1 Post by Abby1680 » Wed May 20, 2026 2:44 am

Hi, recently I purchased what I thought was BU50N from amazon with the hope of using sdftool to flash BU40N firmware onto it for 4K ripping but ran into an issue when I opened makemkv and noticed the drive info. Is there any way to make this drive work or should I just return the drive.

How do you have the drive hooked up?
The Info in Makemkv is incomplete.
I would return it.

I am using a Slimline Sata to USB 3.0 adapter

That is what I thought as well so I already started the return.

Thank you for the reply

Will do Billy.

I will update once the new adapter arrives.

Thank you Billy.
