How to unroot half rooted huawei?????


AC Question

I recently wanted to root my phone so that I could have multiple user accounts so I don't have to worry about my friends going on certain apps. I downloaded kingroot and that finished with 100% working. I then tried xmod with clash of clans and it did not work. After that I downloaded a root checker and it said that my phone IS rooted. My phone progressively got slower and now the 'home' (circle) button no longer works and my phone does not lock. Realising this I wanted to get rid of my root but all the unrooting apps 'failed' or said I wasn't rooted. I've tried the unroot options in kingoroot, kingoroot and superSU and none of them worked. I was frequently getting the you must update the SU binaries but that just sends me back to the original rooting app. After finally realising all this I thought if I could root my phone again it might let me unroot my phone. I have not used a computer at all as this whole situation has only brewed in the last 4 hours.

Thanks in advance,

My phone details:
Huawei Honor 7
Android 5.0.2 Lolipop
