Unhappy [Q] [HELP] Kingoroot . No root access but custom recovery installed

Guys I tried rooting my Galaxy s4 I9500 with Kingoroot which claimed to be an one click root. It failed miserably and what it did though was to install a custom recovery and SuperSU which forcecloses on opening and no application can be granted superuser access. I learnt later that XDA didnt endorse Kingoroot but please Senior members can u help me ! What should I do to go back to stock recovery ? Triangle away doesnt seem to recognise my device as a rooted one. Should I use kies ?
