BU40N - Which firmware is best?

[bachelorbob]

Is there any way to extract / dump the stock BW42 firmware from my hp HLDS BU40N drive on a Mac (connected via an external USB3 enclosure) before I flash downgrade it? Is there a real need for the stock firmware?

Contact Mike Admin. He may want a copy of that firmware. If he can extract it remotely, he should also send you a copy.

Sent extracted FW dump to Mike Admin. PM still unread. No reply.

Would flash with another FW if I could *find* one. Lots of "download this or that," but never a link or location.

Hi!

I bought an HL-DT BU40N which came with firmware 1.04.
I have successfully downgraded it to 1.03mk.
It's ok for MakeMKV but does not work with DvdFab.

I need version 1.00 or maybe 1.01 for DvdFab.
Can someone post them because I searched but couldn't find them?

Thank you

It's unlikely you will get anyone to backup your firmware for you as it takes an hour and no one has anything to gain from this.
It's not new firmware where we have to figure out a new workaround and will add to help the community. The whole point of these new flashers is they are safer to flash as it's the same way the oem updaters work.
If you didn't want to flash your own drive because your scared you should have bought one from one of the sellers

While the guide is much appreciated, finding it and locating the resources are nowhere near as straightforward as they could be. If the forum's board index had a 'download' section, with Windows and Mac sub-sections…

I would also make the 'MK firmware pack' far less cryptic. Folders of BU40N-FR, BU40N-N-Main, BU40N-R-Tier2-Taiwan, BU40N-U-Tier2-Non-UHD (for just the BU40N drive) leave all but the diehards confused. Imagine if the MakeMKV application actually auto-generated a link to download the best firmware for each drive it recognized!

Ultimately, all *I* needed was the sdf.bin, DE_LG_BU40N_1.00.bin firmware, and the correct command line syntax; ALL of which were unnecessarily difficult to locate. Could have taken a few minutes, rather than multiple days of reading.

Speed aside, is it necessary to upgrade v1.00 to v1.03 or v1.03MK to avoid the sleep bug? Or is only a given factory version without it, and flashing will introduce it? Or is there a range of 'good' versions?

Bu40n has no sleep bug at all
