Hey there,

i plan to switch from an LG BP50NB40 (flashed with the BP60NB10 firmware so its UHD-friendly) to an Hitachi-LG BH16NS55. A while ago i read that Hitachi-LG blocked firmware downgrades on some recently manufactured Blu-ray Writer with newer firmware. idk if the BH16NS55 is also affected

I know that there is a small chance that i get a BH16NS55 (if it's also affected) with firmware-downgradable firmware (whats a word )

Do any of you know? Thank you in advance!

the bp50nb40 flashed to bp60 is a better drive than the BH16NS55 in terms of reliability and the speed differnce on BD66 is like 2 mins and on BD100 like 5 mins.
but if you want to downgrade your ripping drive yes it can still be flashed see guide below
