Hey man i see you bricked your phone no worries i'll help you out i've done it myself.
so you're going to need
RSD lite lastest version
4.1.2 xml file for razr m ( just google search it)
I guess you know how to put your razr m in fastboot mood if not you power your device off and hold the power , vol - and sorta click it multple times. until it brings you to the screen. then you should be able to run rsd lite and flash the 4.1.2 xml file would could be found with a single google search. so flashing firmware is pretty easy.. it should be a breeze. after that just leave your phone as it is. motorola will be releasing the 4.4 update swoon hopefully so i would just wait.
hope this was semi helpful
