Mediatek SU, exploit rooting nearly 100 devices, inc. Sony, Nokia, Alcatel, BLU and Amazon

Mediatek SU is an exploit or rootkit, like many others that exist to root Android devices, which basically exploits a vulnerability in devices with a Mediatek processor to obtain temporary root. The procedure is surprisingly simple, since it does not even require unlocking the bootloader of these computers. The only thing that is needed is to execute some commands through ADB from the PC, or from a terminal app on the same phone.

To root with Mediatek SU, download the zip of this script, unzip and copy the “mtk-su” to the directory / data / local / tmp / of the mobile. With ADB you access the shell with the command «adb shell». You change to the mentioned directory with cd / data / local / tmp /, you change the exploit permissions with the command chmod 755 mtk-su and finally you execute it with the command ./mtk-su.

How to root with Mediatek SU (MTK SU). ADB Commands.

If your phone supports MTK SU, the command line will change the adb shell ($) symbol to the superuser or root (#) symbol, from where you can execute commands with root permissions.

This procedure gets a temporary root, which means that you will lose the root if you restart the device and you will have to reload the mtk-su as indicated if you want to get the root again. To achieve permanent root, once the process is done, you must install SuperSU, although apparently this only works if you have an Amazon tablet with Fire OS 5.

Another disadvantage is for devices with Android 6 or higher, where the “Verified Boot and dm-verity” is activated, according to XDA. This means that you will not be able to make modifications to system partitions that only have read permissions, such as the system and vendor partition.

The affected Mediatek CPUs are “virtually” all 64-bit versions, including some of the MT65XX, MT67XX and MT81XX series. There are almost 100 confirmed devices that have been able to root with this exploit, listed below. I say “able” because several of them have probably already been patched to avoid this rooting method (MTK-SU is more than a year old). Possibly several more will be protected with upcoming monthly updates released by some manufacturers, now that this vulnerability has been further exposed.

The mobile brands in which MTK-SU does not work, despite having Mediatek CPUs, are Samsung, Vivo, Huawei / Honor and OPPO (in the latter, provided they have Android 8 or higher), because «they use modifications in the kernel to prevent root access through exploits “, according to” diplomatic “, the creator of this rooting method.

If root is not your purpose, the best thing is that as soon as the next security update arrives on your computer, apply it to avoid being the victim of any app that takes advantage of this vulnerability to get root on your device and be able to install malware, access all your data and in general take control of your Android device. There are apps like this, and in fact Google removed three of these from the Play Store, which got root using MTK-su.

Very unfortunately, it is quite likely that many of the affected devices will never receive an update to this bug, as several are very old and although Mediatek has already patched this vulnerability on all CPUs that have the problem, it will not be able to force the Manufacturers distribute the patch to their users.
