For convenience let's just say you're not using a computer and instead doing this all from the phone you're wishing to switch from Kingroot to SU.

Extract the 'mrw' folder from the zip archive and place it anywhere in '/sdcard'.The two zip archives contain the same files, but if the steps don't return the desired result using the v1 files, then repeat the steps using the v2 files.(Zip archive containing necessary files / v2).

(Zip archive containing necessary files / v1). (Terminal Emulator App / Alternatively you can just use ADB shell). This may leave your device in an unrooted state, if this happens then just run Kingroot again and it will fix itself. I give all credit to w0lfdroid to finding it, and the original guide can be found here The only time I haven't had it work was for a Verizon HTC One M8, since Kingroot only gives (at least at the time) temproot it took a few tries to get it working properly. Okay so I've used this method dozens of times and it works 99% of the time. Kingoroot I can't really speak too much about, considering there have always been many other solutions to achieving root including Kingroot. Kingroot, while it is probably the leading app for '1-Click-Root' solutions, also installs a ton of bloatware and annoying services that you may or may not know about. Kingroot and Kingoroot are two completely different apps, made by two completely different group of developers.
