BU40N Flash Hangs

[tauceti]

I'm trying to flash a BU40N drive from version 1.05 -> 1.03 (see further below for full details of the drive). However, when I run the command:

makemkvcon f -d 'dev_21:4' -f /tmp/sdf.bin rawflash main -i /tmp/HL-DT-ST-BD-RE_BU40N-1.03-NM00000-211810241934.bin

It hangs forever with no progress. I am able to still use the drive after killing the command.
Followed instructions from viewtopic.php?p=181425#p181425 to flash on a linux device. I have no disc in the drive.

How can I troubleshoot this? I include more details below. Thanks!

Command:

makemkvcon f -l
Found 2 drives(s)
00: dev_21:4, /dev/sr1, /dev/sr1
HL-DT-ST_BD-RE_BU40N_1.05_212404231347_MOBP4291705

[omitted second drive]

md5sum of the two files used:

$ md5sum sdf.bin HL-DT-ST-BD-RE_BU40N-1.03-NM00000-211810241934.bin

• sdf.bin is from https://makemkv.com/sdf.bin

• firmware is from https://drive.google.com/file/d/1HRnbXi ... 0FCdM/view

well you dont have enc but thats probably not the problem though
last few version have a flashing bug on linux go back to 1.17 and try with enc and it should work and go to 1.00 after 1.03 as on linux there is also a bug that 1.03mk does not work only the de fw does

Thanks. I ended up addressing this in windows. I'm not sure why it doesn't work in linux. MakeMKV recognizes my drive but would also freeze when trying to load a bluray disc (that I could load in windows; it's not UHD).
What's interesting is that when I would start MakeMKV in linux, it would launch a process `makemkvcon`, which would just hang forever. When killing MakeMKV, I would have to manually kill this process myself.

After flashing in Windows, MakeMKV works in Linux. I also don't see that hanging process named `makemkvcon` anymore.

Here is what I did and the relevant output below/

First, I followed https://github.com/nxyzo/Flashing-Verba ... -to-1.03MK

Double checked my drive worked by loading a disc in windows (unlike linux, the disc loads):

I suggest you now flash the drive to BU40N 1.00 as BU40N 1.03-MK doesn't work very well on Linux.

Hi MartyMcNuts,

I have a couple of questions regarding the flashing of BU40N to 1.00:

1. The procedure is the same as flashing to 1.03?
2. Can it be done directly from stock firmware or the drive should be flashed first to 1.03?
3. Do you have a link to the issues of 1.03 on Linux? I tried searching the forum but I cannot find any specific issue, only other post stating that there are issues

Thanks for your time.
