I just started experimenting with ripping UHD blu rays today and thought I was on the right path but maybe I'm missing something. My WP50NB40 doesn't have any issues reading discs except for UHD blu rays. I flashed it with firmware found in the MK firmware pack 20200720 and get the info below with a UHD blu ray in:

Any help or direction would be appreciated. Thank you!

edit: To add to that, I did use SDFtool flasher to apply the following firmware path:

BP50NB40 to > BP50NB40-NB50-1.03MK then to > BP60NB10 1.02MK or 1.00MK
NB52 to > BP50NB40-NB50-1.03MK with enc > BP50NB40-NB50-1.03MK with bootloader/full flash > BP60NB10 1.00_HBD from Marty download/file.php?id=2143
if using command line add "full" after rawflash

BP60NB10 on any Firmware directly to > BP60NB10 1.02MK

You didn't follow it as your still on bpWp50 firmware if you want me and Marty sell automated flashers that do it all for you
