1.Does Frameroot really only works up until Android 4.2? If yes, are the new Android versions really totally foolproof so that an exploit is definitely impossible to make use of?
2.Is Android 4.3 really worth it or should one stay with 4.2? Stock 4.4 is really uncertain
3.Odin does work with 4.3 but flashing it might lead to bricks, breaking your efs partition and what not.
I assume there aren't better alternatives?
