Can one "saferoot" 4.4.2?
Technically speaking there's no completely safe rooting of any devices, this is because rooting allows complete access to device files. So rooting no there's no really 'safe' way. You can however root your phone and then just be careful with what you install and do on your phone. I honestly don't see much of a reason to root a phone, but if you want to then just be careful. Also there had not been a release of saferoot and probably won't be for awhile due to Android 4.4 KitKat still being a fairly new OS.
