1. Is my device bootloader unlocked
In Fastboot I can see
Device is LOCKED. Status Code: 0
2. Are there any files of razr M that i have to backup first before attempting Unlock and root. I have S4 before buying razr M as my second devices in which i had to backup the efs partitions so that's why i need to know if some backup of razr M is needed.
3.Whats the latest official firmware of Razr M. Currently my device is on 4.1.2.
