Hi all. I purchased the BU40N drive and I see many different firmwares to choose from for this drive. So my question here is, what do you guys feel is the best firmware for this drive? Many thanks in advance.

The guide states:

BU40N on any Firmware directly to > BU40N 1.03MK


Windows? Use SDFtool Flasher

or refer to 1st post of guide, section How To Flash Videos and commands:

Is firmware 1.03 MK better than 1.04 MK?

Is firmware 1.03 MK better than 1.04 MK?

Yes and 1.00 is even better.

Thank you Marty. Yes I've seen that firmware 1.00 allows me to use Leawo Prof Media app which is very useful for creating ISO backups so that I can see the menu option on my discs. But on the other firmwares ex. 1.03 MK and 1.04 MK on the same app doesn't see the drive. However 1.04 MK allowed me to backup Thank God it's Friday bluray via makemkv but on 1.00 the bluray couldn't be read at all for some odd reason. The disc was cleaned but it still wouldn't read. So I currently I'm on 1.00 firmware but I'll be juggling between 1.00 and 1.03 or 04 MK as needed. For example if I run into another disc that can't be read by firmware 1.00 then I'll flash to 1.03 MK for that disc, then flash back to 1.00 after the backup is done. Thanks again marty for your input. It's def appreciated and very useful.

Not a good idea. Stick with one firmware version and do not change it.

You do realize you can only flash a drive x amount of times before the drive becomes permanently stuck on the last flashed firmware version.

Before you ask, no, I don't know exactly how many times a drive can be flashed. When I was testing drives and flashing tools a few years ago, I had flashed a BP50NB40 many times and is now permanently stuck on BP60NB10 1.00-MK. it cannot be changed.

Curious why it would be necessary for an "average user" to need to update the firmware more often than "to make sure it doesn't crash". Once it can read all the disk types, what does a new version gain you?

ok good to know. I'll stick with 1.00 then since it's the best for this drive. Thanks Marty.
