i may have figured it out. but for a while it was telling me that it was patched but whenever i put in backrooms or mario galaxy 4K discs, the disc would stop spinning, it'd tell me no errors at all, and say there's no disc. i think the problem was there wasn't enough power going into the drive maybe

I just got a BU40N and tried flashing it. seems to have done it properly but makemkv is still not reading any UHD discs i put into it. did I miss something?
