I had rooted my Samsung Galaxy S 4G, and for some reason it seems to be only partially rooted now. What I mean by this is that while SuperUser is installed, apps such as BusyBox and Titanium Backup are complaining that they cannot get root access. Using apps from the Google Play store, I can neither remove the root or re-root the device. I cannot get to the Recovery menu because the key combinations done at startup just end up rebooting my device. Why is this happening and what can I do to fix it? Resetting the phone to factory settings does nothing.
Despite all this, AVG Antivirus is complaining that my device is rooted. So, what's up with that?
