I had rooted my wife's RAZR using razrs_edge. The phone received the OTA update to jellybean, and now is unrooted. Everything that I have tried to reroot it gets hung and fails (motochopper and DROID_RAZR_Utility_Jellybean_XT912). Is there a way to get it rooted without wiping the whole phone and reloading the moto jb rom?
