: While often associated with "Step 1" errors, "Step 3" can also occur if the binary is running on a 64-bit architecture when it expects 32-bit (or vice-versa), or if the kernel version is too new for the exploit. about.gitlab.com Common Troubleshooting Steps If you encounter this error while following a guide from or using the MTK Easy SU app , try the following: Re-run Permission Commands : Ensure the binary is executable. Users on have found success by running chmod 755 mtk-su
If you are stuck on a specific phase, could you share your (e.g., MT6765) and your current Android Security Patch level ? That will help determine whether a firmware downgrade is possible or if you need to use a permanent hardware root instead. Share public link
Ensure you have configured it properly by opening an ADB terminal and running the following sequential commands:
The "failed critical init step 3" error in mtksu frequently indicates that patched firmware has closed the vulnerability, rendering the exploit ineffective. Troubleshooting steps involve ensuring execution in /data/local/tmp/ mtksu failed critical init step 3 hot
Some users report that running chmod 755 mtk-su again from the /data/local/tmp directory and re-executing the binary multiple times can occasionally bypass a temporary glitch.
This vulnerability exists within the MediaTek command queue ( cmdq ) driver, which is accessible to unprivileged applications. It allows an app to read and write arbitrary kernel memory addresses. The initialization routine of the script typically follows these milestones:
: If you are running the tool via ADB, ensure the binary has the correct permissions by running: chmod 755 mtk-su Some users report that repeating this command or trying it several times eventually allows the process to bypass the initialization error. : While often associated with "Step 1" errors,
Locating kernel addresses (finding where the "brain" of the phone is in memory).
[Unlock Bootloader] ➔ [Extract Stock boot.img] ➔ [Patch via Magisk App] ➔ [Fastboot Flash patched_boot.img]
: Finds the vulnerable driver structures inside kernel memory space. That will help determine whether a firmware downgrade
If your terminal throws validation warnings, do not try to forcibly remount the system partition as read-write ( rw ). Doing so flags file integrity violations at the kernel level, which blocks subsequent successful boots. How to Recover from a Failed State
MTK-SU (MediaTek SuperUser) is a temporary root exploit originally developed by the developer diplomatic XDA Forums . It leverages a security breach in the
: Confirm your device actually uses an ARMv8 MediaTek processor. The tool will not work on other architectures or manufacturers.
