Hello Koushik Dutta just built his new superuser app which is quite amazing !!!
I just made a CWM flashable zip so that the xda people can grab their hand on it !
I will make flashable zip for all upcoming version ...or you can just update it through Play store !!!
Anyone who has lost their root while flashing a custom ROM may also flash this to regain ROOT !
All credits goes to Koushik Dutta for this amazing app . Do press thanks to him here ---> Click
