I have an app that needs root access but unfortunately it appears I don't have this. I've found a few guides but I've found that some seem to be missing key steps or even contradict each other. Plus there's the ever present risk of bricking the thing. Currently I'm in the 'if it ain't broke, don't fix it' mind frame. My phone is an Xperia Z2 by the way. Does anyone have experience in these matters?
