To flash from 103-MK to 1.00, you don't need enc as MK firmware is not encrypted.
Yeah I know it’s not encrypted. It still won’t flash from 1.03-MK to 1.00, so I’m looking for help with that. I don’t know why it’s not working. SDFtool shows progress up to 100% and says it completes, but the drive is still on 1.03-MK.
Try the RECOVER method and see if that works. In the popup window, choose the 1.03-MK firmware currently on the drive, then in the normal firmware selection drop down box choose the 1.00 firmware.
Thanks this worked! I tried using the Recover method before, but didn't select the current firmware in the popup, so that's why it didn't work before. Now that I have this drive on 1.00 it's now reading 4K BDs.
Are there recommended slim drive enclosures that don't have copy protection built in? The one this new drive came with blocks it unfortunately.

Dunno. I suggest just getting the cheapest one you can but I'd be only looking at one's that use a USB-C connection, not a built in cable.

I purchased this on Amazon: External CD/DVD Drive for Laptop, DVD Burner CD Reader for Laptop, 8-in-1 USB 3.0 Portable CD Players for about $18, December, 2025. I removed the included drive & now use it with a BU40N equivalent. I just set aside the included drive (no use for it). This enclosure has an "attached/captured" USB cable with both a USB-C & USB-A connector for power/data (this cable is removable/replaceable inside the inclosure). It also includes a dedicated USB-C port for additional power only & includes an additional USB-C -> USB-A cable for power only. The other features/ports are just "nice to have".
It's worked perfectly for both flashing & ripping 4K/UHD.
