I have done this, each step reports success, but the firmware reported in the window in flasher never changes. I go all the way to the end, and it still reads blurays, but not UHD.

You are completely off. I never recommended this drive and only got in when you failed to to flash this drive for UHD.


Nobody here said you recommended anything. I never asked you a single question. You jumped in while I was working with someone else.


Your blahblah is not interesting to ...

Look, you started this. As I said, I was looking to buy a drive, and you asked me for info. And then end up complaining that you're tired of babysitting. And now claim you really wanted to help. Please don't. I do not want a babysitter. I will keep trying to purchase a drive, or preferably get the ...

No, not at all. You did it all yourself.
