Is it possible to update from Android 4.2 to 4.4 without disturbing the bootloader?

Question

I have, for example, downloaded an update from android 4.1 to 4.2. All it consisted of was 10 new system apps, 5 libraries, 3 fonts, and a new bootanimation.


What I would like to know is if an update from 4.2 to 4.4 could be done as simply, like by changing out some system apps and/or libraries?

Answer

KitKat has introduced SELinux therefore you can't just update by changing out some system apps and/or libraries.


Nevertheless, while this is a broad statement you may succeed for updating single apk files.
