WH16NS60 with stock 1.03 won't accept new firmware

[DavidGA]

After having killed my second optical drive through overuse I just bought a new WH16NS60. It came with stock 1.03. It won't accept new firmware. I've tried flashing it to 1.02, MK1.02, and MK1.03, but although the flash always "succeeds", the firmware in the drive never changes. Is there some magic trick I need to do?

MakeMKV reports the following drive info:

I'm flashing the drive using "makemkvcon f", an alias for sdftool, on Linux.

This is in the wrong forum, sorry. If an admin could move it to "UHD drives" that would be great. If not, I'll delete it and repost it.

I solved my own problem. This always seems to happens immediately after posting to the forum.

I had to flash with "rawflash enc", not just "rawflash". Now it's fine.
