Flashing does nothing (BU40N)

Post by zavili »

Flashing does nothing to my drive. I have flashed the firmware several times but on MKV it still says Original(unpatched)
I have an A100 drive which seems to be pretty old and rare. Idk if that has anything to do with it.
I could play regular blu rays before flashing but now I can't even if it still says original(unpatched). I have tried with SDF and the command line but still nothing.https://imgur.com/a/GDypehJ

1.00 is the best for BU40n any way

but the reason its not working is your using enc

your reflashing 1.00 so its going to stay 1.00 1.00 is not mk fw its de fw thats native support not re enabled/patched support so its original/unpatched this is normal and expected long as libre drive says enabled you are good
