Mtksu Failed Critical Init Step 3 Best [new] Jun 2026

Some exploits require running before certain services lock down interfaces. Reboot → wait 10 seconds → run MTK-SU immediately.

Usually involves initializing and finding the vulnerability.

KernelSU is a modern, kernel-based root solution for Android. Instead of modifying system files (Magisk) or using a temporary exploit (mtk-su), it integrates directly into the kernel. It's a more powerful, stable, and stealthy method that works on devices with Android 12+ (GKI 2.0) and even some older ones. For MediaTek devices on newer firmware, KernelSU is often the only path to root.

Maps out the kernel memory space and locates the kernel symbol table.

This forces the phone into a state where it accepts external commands before the secure boot kicks in, effectively skipping the initialization step that usually fails. 3. Check Firmware Compatibility

If you are using the GUI app, go to settings and enable with no execution delay .

Overwrites the process credentials in memory to change the User ID (UID) to root (0).

You are using the wrong version of mtk-su for your architecture (arm vs arm64). KernelSU is a modern, kernel-based root solution for Android

This article provides a comprehensive guide to understanding and resolving the "" error, a common roadblock when rooting MediaTek (MTK) Android devices using the mtk-su tool.

: The setenforce 0 command is temporary . Once you reboot your device, SELinux will revert to its default enforcing mode. This is perfectly fine for the purpose of completing the rooting process. Once you have permanent root, you can explore more sophisticated ways to manage SELinux.

mtk-su (or simply "mtk-su") is a specialized binary designed to exploit a security vulnerability (CVE-2020-0069) found in many MediaTek chipsets in Android devices released before 2020. It gives users a temporary root shell ( $ changes to # ) without needing an unlocked bootloader or a custom recovery, making it a handy tool for modifying system files or as a stepping stone to install a permanent root solution.
