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.
