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 anybody. Co...

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 &...

Thanks very much!. On the first step, it successfully writes the bp50nb40-1.03mk firmware. When completed, the firmware shows as having been unchanged. The original firmware is there.

Would it be possible to get a link to the info you believe is right? I am not really being lazy, but I have read some conflicting information, and the thread you referenced has 1,420 posts. I really appreciate the help, thanks!
