adb shell setenforce 0 (Note: On stock ROMs, this usually fails without root.) mtk-su supports arguments that can help bypass step 3 failures. Try:
For years, mtk-su has been a lifeline for Android users with devices powered by MediaTek (MTK) chipsets. This powerful command-line tool, developed by XDA Recognized Contributor diplomatic , allows for temporary root access and the exploitation of CVE-2020-0069, a vulnerability in MediaTek’s kernel. However, as Android versions have evolved and security patches have rolled out, users are increasingly encountering a frustrating roadblock: failed critical init step 3 . mtk-su failed critical init step 3
Notice the pattern: Patch date is king. For the technically curious, “step 3” in mtk-su roughly corresponds to the do_root function after the selinux_set_root call. The exploit uses a technique called arbitrary kernel read/write to modify the current task’s credentials ( cred structure). Step 3 fails when the kernel’s commit_creds() function returns an error or when the kernel’s task_struct validation detects an inconsistency—like a UID that doesn’t match expected security capabilities. adb shell setenforce 0 (Note: On stock ROMs,
