Info on flashing LG BU40N

#1 Post by filmgeek47 » Mon Apr 06, 2020 7:14 pm

Hi all,

Have run into a few troublesome discs on my Asus drive, so I've purchased an LG BU40N to try. A little confused on what to do assuming the drive comes with the newest factory firmware. It sounds like I need to cross flash it to a different drive and then downgrade. Which drive though?

Is it the general consensus that the BU40N tends to have fewer issues than other drives?

You should post what Makemkv reports about your firmware since there are several versions of MK firmware for this type of drive. We'll see then.

That question was answered here now:

The OP created a whole new post for this again for some odd reason anyways.
