Help, Re-Rooting?

A

AC Question

Hi Guys,

I rooted my I545 s4 a while ago, didn't run any crazy roms or anything, just wanted to remove bloatware basically. Anyways, I was going to update and or run a different rom and I accidently hit "un-root" in the SuperSU app. So I unrooted my phone, well now I want to re-root it, and have tried using different methods (motochopper and kingo root) and both have failed. SuperSU was uninstalled, and the phone is un rooted but something is preventing me from re-rooting. The only things I have seen:

While running moto:

pkg: /data/local/tmp/Superuser.apk
Failure [INSTALL_FAILED_ALREADY_EXISTS]
[-] Failure.

kingo says nothing.

I am currently running 4.3

Any help would be great. I realize I have the option to do a complete factory reset and re root afterwards, but have been trying to avoid this, don't want to have to reinstall everything, apps, contacts, etc etc. Thanks.
