You also might be able to tell SuperSU to go ahead and update the binaries and then run through the process starting with the Prep utility and let it continue from there and continue running it, it will work. ** Android 5.x - 8.x users, you will get several kingroot pop-up boxes, just keep closing them and then go back to Super-Sume Pro, unless Super-Sume Prep is still listed, then run that again and make sure it is getting SuperSU access. I will work with you to resolve the issue.
If I ask you to email me and you do not, don't complain about it not working for you. Guys, please leave a review so I can get a feeling of how the program is working. If you are running an older version of KingRoot, prior to 4.1, you need to upgrade it prior to running this for best results. > Kingroot 5.x has a silent install option in it's settings, under Advanced make sure that is disabled !! Once in there look on the top right for the three dots and tap that and choose disable <. ** Major Update - Have finally defeated their KingRoot 5.x protection mechanisms !! ** (If it says your device is write-protected, that is not the apps fault, do not leave a bad review for something that is due to your device.)
Also, turn OFF KingRoot Auto Update after you are rooted and prior to running this. If you do NOT see SuperSU after the process is complete, go to the Playstore and install it and then open it. It is not advisable to uninstall this after KingRoot removal, because this fights for root in case KingRoot tries to reinsert itself again after a reboot, etc.
