The mtk-su tool works by bypassing Android's kernel security permissions in memory. It executes a series of initialization steps to locate security structures inside your phone's specific MediaTek processor.
If you attempt to run the 64-bit (arm64) version of mtk-su on a 32-bit kernel, the binary will fail to execute properly, often showing the "Failed critical init step 3" error in the process. With 32-bit devices becoming rare, this is still a possible reason. Choosing the wrong architecture for your device's kernel—such as using an arm64 binary on a device that only supports armv7l—will cause the exploit to fail at the initialization stage. mtk-su failed critical init step 3
Understanding the root cause of this error—and learning how to troubleshoot it—can help you safely attempt alternative root options. What is mtk-su? The mtk-su tool works by bypassing Android's kernel
To resolve the "mtk-su failed critical init step 3" error, try the following steps: With 32-bit devices becoming rare, this is still
