LG BU04N 1.04 flashing errors

[myriadfacade]

Hi MakeMKV Forum,

Apologies if posting in the wrong place, first time doing so!

I recently brought a LG BU40N with a slim sata -> USB cable. I've tried to flash HL-DT-ST-BD-RE_BU40N-1.04-NM00500-212005061142.bin but fails using both the command line and SDFToolFlasher. SDFToolFlasher doesn't appear todo anything when I click Start. And the command line I'm getting different errors from Linux and MacOS.

On Linux I'm getting the following:

Code: Select all

/opt/makemkv/bin # ./makemkvcon f -d /dev/sr0 rawflash -f /tmp/sdf.bin enc -t mtk19xx -i /storage/HL-DT-ST-BD-RE_BU40N-1.04-NM00500-212005061142.bin

The Ultimate UHD Drives Flashing Guide says:

BU40N on any Firmware directly to > BU40N 1.03MK


I would expect your MacOS command to be (assuming it has encrypted firmware):

Code: Select all

$ /Applications/MakeMKV.app/Contents/MacOS/makemkvcon f -d /IOBDServices/9360E6E7 -f <path to sdf.bin> rawflash enc -i HL-DT-ST-BD-RE_BU40N-1.04-NM00500-212005061142.bin

looks like your sata to usb chipset is not passing through flash commands

@Billycar11 Oh interesting. I shall try and find another cable and try flashing again!

@dcoke22 I did try that image too, but if the new cable works I’ll be sure to flash that image instead of the 1.04.

Thank you both.
