I recently acquired the
Asus Zenfone 2 from
Amazon, because I crave a 6 inch screen.
Now I need to root the device in order to run
Kali Linux. I also want to root, because I am a control freak.
Here are the steps assuming you already have ADB and Fastboot installed on your PC.
Download to your PC the right TeamWin Recovery Program aka TWRP
Rename the download to recovery.img and move it into the same folder as the adb.exe and fastboot.exe
Download the SuperSU zip file to the microSD card that will be inserted into your Asus Zenfone
Connect Asus Zenfone to your PC via USB
Open a command line from within the directory that contains adb.exe, fastboot.exe and recovery.img
Type: "adb devices" to verify that the Asus Zenfone is indeed connected
Type: "adb reboot bootloader"
Type: "fastboot devices" to verify that the Asus Zenfone is indeed in Fastboot mode
Type: "fastboot flash recovery recovery.img"
Type: "fastboot boot recovery.img"
Use the TWRP menu interface on the Asus Zenfone to [Install Zip] the SuperSU file on the microSD card.
Done.
For kicks you may also want to visit the
Asus support site for additional software tools.
