Some forks exist (e.g., modded for newer kernels). Try searching for "mtk-su mod final".
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.
exploit has failed to initialize its protocol, often because the specific security vulnerability it relies on has been patched by the manufacturer. Core Causes of Step 3 Failure Security Patches
Before dissecting the error, it is crucial to understand what mtk-su was and why it became so popular.
Some users have reported success on newer patches by using of mtk-su that target different IOCTL codes or different drivers (e.g., mtk-mem or kpm ). However, these are rare, device-specific, and often unstable. They are not universal solutions.
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: .
