The Asus Zenfone 2 Laser can be rooted using some adb commands from a Windows computer for installing the pre-rooted firmware. The pre-rooted firmware will let you install the same applications you could install with the older root method you had. Furthermore, it will pair nicely with a custom recovery so you can start installing any custom ROMs or custom kernels that you might want to try.

These are the guidelines to root the Asus Zenfone 2 Laser with the Z00LD or ZE550KL model numbers:
