"There is no SU binary installed, and SuperSU cannot install it." This message keeps on flashing on my Micromax canvas gold A300. It runs on 4.4.2. I've tried installing superuser, framaroot and supersu but I'm unable to root my phone. Can somebody please tell me how to root my phone step wise? I'm a total newbie at this thing. And another thing is that after rooting my phone will I be able to make my phone storage as default storage? I'm having problems downloading apps as they download to internal storage by default, and I've run out of space.
