This is the safest method for modern MediaTek devices running newer Android patches.
Using the wrong variant can cause errors ranging from “cannot execute binary file” to the dreaded “Failed critical init step 3”.
When you run mtk-su , it executes in sequential phases. If a phase fails, it halts the program and throws an explicit error message (e.g., Step 1, Step 3, Step 4). 1. Security Patches and Fixed Exploits
Google and MediaTek frequently update the kernel to patch security vulnerabilities. If your device runs a recent Android security patch (usually from late 2020 onward, though it varies by device), the vulnerability used by mtk-su has likely been patched. 2. Android Version Incompatibility
If you are trying to root, it is recommended to focus on conventional methods, such as unlocking the bootloader via fastboot , rather than relying on mtk-su on modern Android security patches.
If the shell prompt changes from $ to # , you have successfully obtained temporary root access. If you still see the error, try re-downloading the binary, as the file may have been corrupted during the initial download.
To help find an alternative rooting path, what is your device? Sharing your current Android version and Security Patch date will also help determine if a firmware downgrade is possible. Share public link
If your device allows firmware flashing via MediaTek's proprietary , you can search for an official firmware package for your exact model dated prior to March 2020. Flashing an older "scatter file" rolls back the security patch level, allowing mtk-su to initialize flawlessly. 2. Transition to Traditional Bootloader Rooting
If you are using an app interface like MTK-Easy-SU and it fails, try dropping to a manual ADB shell to check for hidden permission blocks.
: The mtk-su binary must have proper execution permissions. If it's missing these, the initialization steps will fail immediately. Potential Fixes & Workarounds
