Need a little help flashing firmware to BU40N drive

Post by gps1539 »

Hi

I'm trying to flash firmware DE_LG_BU40N_1.00.bin (or DE_LG_BU40N_1.03_MK.bin) to a BU40N Bluray drive and need some help, thanks in advance.

I'm running arch linux. I installed makemkv (v1.18.4). When I open makemkv > about, it says the latest version is 1.18.3 (older?) and my license type : Freeware, Evaluation : Ended, Version expires 10/9/26.

makemkvcon seems to find my device, note no disk inserted.

Code: Select all

makemkvcon --robot info dev:/dev/sr0
MSG:1005,0,1,"MakeMKV v1.18.4 linux(x64-release) started","%1 started","MakeMKV v1.18.4 linux(x64-release)"

From various searches including this forum I tried to run the following to flash the firmware from MartyMcNuts all you need zip
$ sudo makemkvcon f --all-yes -d /dev/sr0 rawflash main -i "./DE_LG_BU40N_1.00.bin"

The command appears to be running according to top, but is has been running for over an hour with no errors or progress.

Any ideas what is going on? how to get progress or error output? Is Evaluation or purchase required to flash firmware, if so why is evaluation "Ended" on day zero?

Download https://makemkv.com/download/old/makemk ... 7.7.tar.gz, untar it, cd into the directory extracted, and run ./makemkvcon ... instead.

Thanks, I just logged back in to provide an update, yes newer versions seem to be broken on Linux.

I found a thread on using older versions for Linux and with 1.17.7 I could flash the firmware, but 1.17.7 refused to read a disk as the version was 'too old' and 1.18.4 just runs forever.

Thankfully with the firmware update I can now read Bluray disks with handbrake, so I'm deleting makemkv.
