[AC Question]

No matter what I've tried, SuperSu does not work on my LG Optimus F3.
Motochopper failed. Saferoot failed. Framaroot failed. Kingoroot failed. It installs the shortcut for SuperSu, but it ALWAYS says that there is no binary installed and doesn't work for me.
I've uninstalled and re-installed SuperSu (with reboots) several times on the advice of forums, but it's never any different. Can anyone help??

SuperSU is doing the right thing. The binary it is referring to is SU aka SuperUser aka Root itself. It's telling you you don't have root like it should. Supersu is not to blame, your root tools are.

In addition without the superuser or SuperSU app, no existing apps can successfully ask for root permission and thus you may as well not have a rooted phone in the first place. In fact it's dangerous as a malicious app can access SU without the SuperSU intercepting it, as if it was supersu... effectively granting any malicious app that wishes root permissions.

Try iroot.
