Root MediaTek ARM V8 Devices Using MTK-SU Tool

In this guide, we will tell you how to root MediaTek ARM V8 Devices using MTK-SU Tool. Any phone, tablet or TV box based on Mediatek MT67xx, MT816x or MT817x chipset can be rooted using this method.

Everyone in Android Community knows about Rooting and there are a number of people who want to Root their Android. Phones with Snapdragon and Exynos processor have a lot of third-party development, developers post methods to Root these devices but  MediaTek and Kirin devices don’t see much development. MediaTek processor is generally used in low-end devices which don’t sell a lot. But  MediaTek Processors have a flaw, using which XDA Senior developer diplomatic as created a tool MTK-SU to root MediaTek ARM V8 devices.


Root MediaTek Devices using MTK-SU Tool

It’s a tool created by diplomatic, MTK-SU takes advantage of the weakness in the Chipset software design. It was originally created at helping Amazon Fire  HD Tablets and Fire TV gen 2. Amazon ships most of there Amazon Fire Tablets with MediaTek chipsets. But the funny story is, this method works on all the MediaTek’s 64-bit chipsets.

It means we can root all Mediatek V8 chips, it doesn’t matter if the device is Phone, Tablet or TV. So to root a MediaTek device with MTK-SU you don’t even need to unlock your device Bootloader, you can root the devices even when the Bootloader is locked. But the root is temporary and the device is unrooted after reboot.


You may already know that Rooting device voids your warranty. To root you will be using third-party software and tools. Using these tools is at your own risk.

Before you proceed with the rooting the device make sure you have a backup of all the important contents of your phone.

Steps to root MediaTek devices

  1. Download the MTK-SU file from the above download link, if you want the latest version of the tool, check the source link at the bottom of this article.
  2. Unzip the file and there will be two folders “arm” & “arm64” with an ‘mtk-su’ binary in each folder. Pick one for your device.
    • arm: 32-bit userspace on a 64-bit or 32-bit kernel
    • arm64: 64-bit kernel and userspace
  3. Connect your device to ADB and use below command to push mtk-su to your /data/local/tmp folder
    adb push path/to/mtk-su /data/local/tmp/
  4. Next, open adb shell
    adb shell
  5. Change to your tmp folder
    cd /data/local/tmp
  6. Add executable permissions to the binary
    chmod 755 mtk-su
  7. Finally, run the below command and make sure your device screen is on and don’t let it go to sleep

This should provide you the root shell. It takes a second or a two second if the program gets stuck more than a few seconds and your device screen is on, Just press Ctrl+C to close it. Run the following command, for verbose print which helps the developer in debugging any problems

./mtk-su -v

The output of the command will be something like this.

P00A_2:/data/local/tmp $ ./mtk-su -v
