Here is the thread you are looking for, basically just root with Z4Root, download the new version of ES File Explorer from the official website and install, once in ES explorer go to menu>settings>Enable root access (or whatever it says along those lines) and then find the telephony.apk and phone.apk in the system folder, rename them to something else (telephonyOLD.apk or something).
