A little correction, the BH16NS55 is ready for 4K or 4K flash even with production date 2015 :wink: Not before October 2015 unless you are willing to risk it. Must be MT1959 drive platform.

I doubt it. But better check it out instead throwing it in the tin unchecked.

Has power connection changed?

Reading BD works? Other BD-R brand tested?

You can try to clean the laser lenses with alcohol and q-tips. Do it twice and dry immediately, not let it dry by air.

If that don't work you can assume that the blue laser is defective.

The BU40N is the best one from LG.
Enjoy it with firmware 1.03MK.

There are no Not-MT1959-plattforms with the BU40N available.

Checked it with another cable oder with another USB port? Also you can try to extract the drive carefully and try an USB to Mini-SATA adapter for the flashing process.

Somebody may correct me, but if you have an Buffalo BRXL-16U3 without a Pioneer drive but a LG, it has the older and not compatible MT1939 platform.
Buffalo used LG BH10 oder BH12 drives in earlyer 16U3 a far as I know.

Please post your MakeMKV drive infos first.

Yes, it's flashable. Check the Ultimate Flashing Guide.

Test it with the LG WH16NS60 1.02MK firmware.
