BU40N firmware flash

[georgesgiralt]

Hello !
I own a BU40N which came with "A103" firmware.
As I could not back up the firmware present on the drive (I got a 70kb tar file instead of the expected 2Mb binary) , I suspected the HL-DT-ST firmware was encoded.
In order to turn LibreDrive on, I flashed it with the 1.03 firmware using this command (Ubuntu Linux) :

Code: Select all

makemkvcon f -d /dev/sr0 -f sdf.bin rawflash main enc -i  HL-DT-ST-BD-RE_BU40N-1.03-NM00000-211810241934.bin

This ran fine ! :

Code: Select all

But as I own another BU40N which has a more lax firmware (dump_full_HL-DT-ST_BD-RE_BU40N_A100_211701021159_XXXXXXXX.bin ) I tried to put it on this drive and got errors. Even with or without the "enc" option in the command line.
So my question is :
Is it possible to put this firmware on this drive ? (both drive looks exactly the same except the serial number and date of manufacture)
if yes, what did I do wrong ?
Many thanks in advance for your help.
Have a nice and bright day !

Follow the guide man why did you change the firmware you were trying to flash
