Proper firmware for BU50N

Post by harryshuman »

Hello,

I got this new BU50N Drive with the following info provided by MakeMVK:

Code: Select all

Drive Information
OS device name: E:
Manufacturer: HL-DT-ST
Product: BD-RE BU50N
Revision: CC04
Serial number: 103HS030502
Firmware date: 2120-05-29 09:18
Bus encryption flags: 1F
Highest AACS version: 82

LibreDrive Information
Status: Possible, not yet enabled
Drive platform: MT1959
I attempted to flash it using version 1.00 firmware I found, but it throws an error 0x82052603. I couldn't find any other firmware for it, but I see people online mention BU50N is similar to BU40N.

Which firmware should I use to bypass the error?

Thanks, I used the BU40N 1.03 firmware file and it worked like a charm (it's my second drive). I just didn't know whether BU50N was any different.

Out of curiosity, is there any benefit to flashing the drive to 1.00 firmware after 1.03 or can it just stay at 1.03?
