I just installed my new drive. I checked that the drive is working and opened MKV and see the attached info for drive.

I downloaded the latest flasher and it sees the drive but when I select the 14NS40 firmware I get a checksum message and says try again. See screenshot.

Anything I may be doing wrong?

Your doing many things won't I recommend you get my automated flasher since you are not understanding the guide.
Email me can be found below send em your makemkv drive info section

I sent you an email.

I was able to flash my 14SN40 and it now on the 16NS60 1.02MK version per the thread. Something is not correct. Because when I put a UHD disc in, it just spins and says trying to load. Eventually it stopped and said no disc.
