Mtk-su Failed Critical Init Step 3 [better] -

What is MTK-su?

I’m trying to get temporary root on my MediaTek device using mtk-su , but I keep getting stuck at:

Deconstructing the Error: What is "Critical Init Step 3"?

setting up the kernel memory mapping or creating the necessary kernel structures

Specifically, "Step 3" usually involves for the exploit to execute code. If this fails, it typically means the specific exploit binary you are using is not compatible with your device's hardware revision or firmware version. mtk-su failed critical init step 3

If the exploit is patched, the only way to make mtk-su work is to revert to an older, vulnerable version of your device's software. What is MTK-su

Firmware Patch

: Your device may have a security update released after March 2020 that patched the vulnerability . If this fails, it typically means the specific

Patched kernel

| Cause | Explanation | Possible solution | |-------|-------------|--------------------| | | Security update fixed the exploit | Use a different rooting method (Magisk, unlocked bootloader). mtk-su works only on older Android versions (typically 9–10, early 11). | | Incompatible SoC | Not all MediaTek chips support mtk-su (e.g., Helio G95, P90, Dimensity series may fail) | Check the developer’s supported list. Dimensity series rarely work. | | SELinux enforcing | Step 3 may require permissive SELinux | If your kernel is vulnerable but SELinux blocks, you cannot change this without root. | | Incorrect shell context | Running from a non-ADB shell or restricted user | Run from adb shell or a terminal emulator with proper privileges. | | Mitigations enabled | Some vendors added extra checks | No fix — vendor hardened the kernel. |
