I rooted my LG-D415 (Lg Optimus L90) with towel root in December. It was fine until a week ago where i couldnt use Superuser Su anymore because it says no binary was installed. Root checker says that my phone is Not rooted but aanother root checker says it is. T-Mobiles device health center also says my phone is rooted. I cant use Superuser Su to uninstall root because it says I have no su binary installed. I downloaded many file managers and tried to delete the su file from system/bin but its not there. Also when i try to deleye the su file in system/xbin it always crashes. Also i cant find the superuser apk in system/apps to delete that either! When I try to use towel root to try and root again it says your device is not supported. Please help me uninstall this root.
