[Q] Rooted but can't get any ROM installed topic

@sd_shadow, I rooted my droid razr T912 using the iRoot method. I have bootstrap 3.72 installed and I had made a back up of the image prior to installing CM 11. I'm running into errors installing anything on my razr now. I tried to go back to my old image copy but I erased system along with dalvic, data so now it won't boot up. I still have access to bootstrap, can you help me please? Do I need to restore the factory image or since I have bootstrap is there a way to get a new image on without the system files?
