Re: SDFtool Flasher

Post by dfechser »

I'm new to this so please be kind...
I've downloaded the SDFtool Flasher and the firmware file (I have a BP50NB40). I can see the list of encrypted firmware. How do I find out what firmware is currently on my drive in order to compare it to the list?

Thank you,
DFex

When you launch MakeMKV itself, it will show your optical drive model, its firmware version and date. That and the SDFtool Flasher [url]viewtopic.php?f=16&t=22896[/url ] first post will tell you how to flash your drive. Note that your BP50NB40 if SVC: NB52 (a tag on the bottom of the drive) takes a two step process to make it UHD capable.

Near the top of the Ultimate UHD Drives Flashing Guide there's a section that starts with "Stop Read Before Flashing". Item 2 on that list is Drive Platform MT1959. Your drive says it is drive platform MT1939. That's an older drive platform that does not support UHD. The SDFtool is saving you from flashing the wrong firmware onto the drive and rendering it unusable.

The drive you have maybe be new and unused, but it is not modern. If you can, return it.

As dcoke22 said, it might be new but it is an old drive with the old MT1939 drive platform. The firmware on it is from 2013 so at least 12 years old!!

Can you type here what the label on top of the drive says? Or attach a pic of the label?
Cheers :D
