Unroot phone without root access I remember rooting my LG G3 like two years ago with Stump Root. Now I don't use root anymore. My bank app doesn't work because my phone is rooted. Now I want to remove root from my phone. I found out that I can remove root access from my phone when I remove the su binaries from the phone. I downloaded ES Explorer to do so. ES Explorer told me that I don't have root access. Now I can't remove the su binaries.

How do I unroot my phone now? And why thinks my bank app that I have root even though ES Explorer and root checker both tell me that I don't have root access?
Install the SuperSU app and go into settings and perform a full unroot... If that fails you will likely need to flash the full factory KDZ image and return to pure stock, be aware this procedure will wipe your device and all user data stored on it.
