(Does OK6 is a newer version? maybe thats the problem)
I've already disabled Device manager, remote controls and reactivation lock.
are a newer version than UBUCNH1? do they work on 5.1.1?
thanks in advance!
yes those are the ones you should flash if you want to update. for N900W8, CNxx is KitKat (4.4), 2DOxx is Lollipop (5.0)
OK6 is for international/N9005XX models only, which is why it failed auth, and good thing it does or you'd have bricked your phone!
your camera issues are more likely related to incompatible kernel and proprietary .so files (they need to match up)
these are a few possible paths that commands can take to the hardware, sorted by most common to least common AFAIK:
1. android -> translation layer & extra functions libraries (proprietary .so files) -> kernel -> hardware
2. android -> kernel -> hardware
3. android -> translation layer & extra functions libraries (proprietary .so files) -> kernel -> firmware -> hardware
4. android -> kernel -> firmware -> hardware
see the firmware stage of communication. sometimes this firmware is included as part of the kernel, and the respective kernel drivers will flash the firmware for you if it needs updating. sometimes, very rarely, the firmware will be part of the modem or bootloader binaries instead of flashed from kernel. this is a situation where updating bootloader/modem could potentially help.
this is only from reading lots of samsung kernel sources, so some of it is only assumed. i can't know everything.
if anyone wants to share more accurate information than what i can provide, we would all be thankful!
