Hi,
I used to use KingRoot to remove root of my smartphones most of the time with success but not for UMI Diamond so my question: do you have a same appli to do the same sussessfully?
Thx
Though Kingroot works fine for rooting the android device it sometimes halts in the middle and causes the device to restart. I would prefer you go with 360 root app: https://360rootdownload.info
