05-15 23:22:41.020 E/SuperSU ( 938): SU BINARY IS NOT RUNNING AS "u:r:init:s0" - THIS WILL CAUSE ISSUES

PS. A few tour of dancing and root access restored.

1. using Kingo Root (mode "Root Again")

2. Will be installed 2 apps - Kingo Root and Kingo User. You will give root access

2.1 Now KingoRoot can be uninstalled

3. (Next step for me) Via adb copy SuperUser.apk into /system/app dir

3.1 Run SuperUser. Update SU binary in normal mode

3.2 Run EZFile Explorer. Grant root access in "/" directory on RW

3.3. Delete KingoUser.apk from /system/app

4. Reboot
