Hi,

I'm hoping someone can give me some advice to force flash my BU50N optical drive to the correct firmware.

The drive has the wrong firmware. I know the drive is a BU50N and that one of the admins on this site said to treat the drive as BU40N, so I have tried flashing via the SDFtool Flasher & Makemkv built in flasher. The both completed sucseesfully but the drive info is still the same (BD-RE BP50NB40).


Drive Information
OS device name: D:
Manufacturer: HL-DT-ST
Product: BD-RE BP50NB40
Revision: 1.03
Serial number: *********
Firmware date: 2120-05-07 09:17
Bus encryption flags: 17
Highest AACS version: 57

The firmware I have attempted to flash to is HL-DT-ST-BD-RE_BU40N-1.03-NM00000-211810241934

I would appreciate some advice please,

Thanks in advance.

see guide below you may need to follow nb52 steps and there is a new boot code section you can use for nb52 drives

or email me or marty for an auto flasher

Hi Billycar11,

Thank you for your reply.

I managed to use the crossflash method to get the correct firmware on the drive.

makemkvcon64.exe f --all-yes -d D: rawflash "main,nowait,nocheck,boot=MT1959 Boot BUP3"

All good now
