Hi, i just bought a razr m which is on jellybean 4.1.2 (98.18.72)..by checking system updates i get the notification that my system is already up to date :eek:

Is there any way to manually update to a Kitkat version by which i can root the phone and install custom lollipop roms?

Please excuse me if the question has already been asked but i wasnt able to find it, thanks!
