Mtk-su Failed Critical Init Step 3 Jun 2026
Sometimes the issue lies outside the software entirely. Faulty USB cables or ports can interrupt the ADB connection during the pushing or execution phases. Users have reported that switching to a different microUSB cable or USB port on their PC resolved similar MTK-SU issues.
If you share your in the comments, I can help determine if there’s any workaround for your specific case.
The timeline for this vulnerability is particularly telling: discovered by MediaTek in April 2019, exploited in the wild, and finally patched by Google in March 2020. If your device received the March 2020 security update or any update thereafter, the vulnerability is almost certainly patched, and no amount of troubleshooting will make mtk-su work. mtk-su failed critical init step 3
One of the simplest potential fixes involves temporarily setting SELinux to permissive mode before running MTK-SU:
multiple times if it fails initially, as it sometimes requires repeated attempts to "take". Run Multiple Times : Community members on Sometimes the issue lies outside the software entirely

The primary culprit is a locked-down Android operating system. The vulnerabilities targeted by mtk-su were systematically patched by MediaTek and Google in security updates. If your device has a kernel compiled after March 2020, the exploit mechanics are likely blocked, leading to an initialization failure. 2.

: mtk-su provides only temporary root access that does not survive a device reboot. This is by design, as the exploit grants root privileges to the current shell session only. To achieve persistent root, you must use the temporary root to install Magisk or another root management solution that persists across reboots.
