Flashed LG WP50NB40 (NB52) but get "No disc inserted" with UHD

Post by lesty »

Hello, I recently got this drive and tried my best to follow the tutorial on the site to flash my drive. I used the SDFtoolflasher to flash BP50NB40-NB50-1.03MK then flashed BP50NB40-NB50-1.03MK with bootloader box checked and then BP60NB10 1.00_HBD (from Marty). Unfortunately my drive can't seem to read the UHD disc I have. It reads normal Blu-rays fine. it seems to just be a problem with UHD discs. I just bought this disc and tested it in my PS5 and it seems to work fine unfortunately it's the only disk i have to test at the moment. I'm not sure if I flashed the drive wrong so i've included the MakeMKV info i get when the disc is inserted. Any help or suggestions would be much appreciated.
