[Unrooting] Need help UNROOTING Xperia Ultra T2

[bakababi]

I rooted my Sony Xperia Ultra T2 D5303 Version 4.4.3 19.1.1.A.0.165 using Kingoroot and realised I couldn't access one of my apps, now when I tried to unroot it using the Android Application, it does not respond at all and if I tried to unroot it through the desktop application it always gives a "Unroot Failed" message whenever it reaches 100%. How do I unroot the phone fully?

Sorry,kinda of a newbie here. Tell me if you need more details.

Download supersume on playstore, it will change your root manager to supersu and just unroot from supersu if you want
