I'm on stock (rooted,UB) with phantom kernel v4.5 [C2105].I installed it,the phone booted fine,the camera is changed,I can't say for now if it's good or bad,I don't see much difference,but it time maybe I'll see some ups or downs.About other tweaks like battery and ram,I can't say anything for now.I just posted this to say that my phone booted up just fine.
C2104 users read the first post well...you must do something before flashing this in order to not get bootloop.
