Keywords

Root:

Assuming superuser access, it’s technically similar to granting administrator status on PC. You can do almost anything in root status.

Recovery mode:

Also known as Recovery (below), is an Android system mode that allows user to modify internal system data.

SU:

Short for "Substitute User" command, is the key to grant root access in Linux.

Installation

Intro :

In order to make SuperSU work, one need to root his/her cellphone. Rooting can be done through two methods: using Android Application Package (APK), which is usually provided by 3rd party rooting service; or manually granting root access (can be achieved in recovery mode).

APK :

Pros: Easy for beginners, fast rooting process.
Cons: Must maintain root status, and able to uninstall other root ware

Recovery:

Pros: High success rate, free from SU files update issues
Cons: Need to unlock phone with bootloader and support flashing CWM recovery

Flashing into recovery mode

There is a few ways to flash your phone into recovery mode. One method is through USB debugging with a PC. Before rooting, one need to download recovery image and SuperSU zip packet that fits the model of your phone. After download, rooting and installing SuperSU can be achieved through the following process:

Step 1: Enter developer mode: Go to Settings----Software info----Build number, touch 7-8 times to enter developer mode (it will pop up on the bottom of your mobile screen)

Step 2: Turn on USB debugging mode and unlock phone (may require bootloader)

Step 3: Use a USB cable to link to computer, move SuperSU zip packet into SD card

Step 4: Reboot recovery mode.

Step 5: Select installing SuperSU.zip file

Step 6: After successful installation of SuperSU, the system will reboot and ask if maintaining root status, select yes.

Note: the system will reboot (maybe a few times or may take a little while) and the SuperSU app will appear on your mobile screen with full access monitoring your apps.

Troubleshooting

Q: How do I complete SuperSU binary update?

A: The problem often occur when rooting with third-party rooting app.it is possible that the rooting app either deletes SuperSU’s SU file or closes user’s root status after granting root. Thus we highly recommend rooting manually through Recovery mode.
Q: How to root?

A: Rooting can be done through a few methods, one can always refer to the process above for rooting and installation of SuperSU.
Q: Why I failed when I try to run the TWRP update?

A: One must have TWRP recovery AND the recovery packet can support ADB debugging. Once completing the two requirements above, TWRP should be working just fine.
