Temporary Root

What is temporary root?

If you have rooted your device with Kingo and then lost it after reboot (also called "temporary root"), it is also caused by locked bootloader. Locked bootloader will prevent your device from being permanently rooted. This situation always happens on devices manufactured with system protection mechanism such as SONY, HUAWEI, HTC, LG, MOTOROLA, etc.

In this case, you need to unlock your bootloader first so that the root can be permanent. Or, root your device again after rebooting.
