Hi,

I’m unable to flash a BU40N OEM internal slim drive with the libredrive firmware. Flashing reports successful, but after power cycling, the drive still shows “Possible, not yet enabled”, and the CB05 version.

I’ve directly connected it to my motherboard with a SATA cable.

Using Makemkv 1.17.6 from:

sdf from here:

Does anyone know a sequence of images to flash that will allow the drive to accept a libredrive firmware?

Thanks,

Please post your MakeMKV drive info.

Thank you! Dropping the `enc` worked.
