If the software-based exploit fails at Step 3, the device's security may be preventing the "handshake."
This forces the phone into a state where it accepts external commands before the secure boot kicks in, effectively skipping the initialization step that usually fails. 3. Check Firmware Compatibility
If your device has a security patch newer than March 2021, the mtksu vulnerability may be patched. mtksu failed critical init step 3 best
To consistently bypass "mtksu failed critical init step 3," the most effective method is If the software fails, the hardware test point remains the gold standard for forcing a successful initialization.
Below is a comprehensive guide to understanding why this happens and the best methods to resolve it. Understanding the Error: What is "Critical Init Step 3"? If the software-based exploit fails at Step 3,
Look for an older version of your device's official firmware (Fastboot ROM). Flashing an older version can re-open the exploit path. 4. Adjust Tool Settings (MTK Bypass Tool) If you are using a GUI-based bypass tool alongside mtksu :
Ensure you haven't selected "Auto." Manually select your specific SoC (e.g., MT6765, MT6762). To consistently bypass "mtksu failed critical init step
The mtksu exploit relies on specific vulnerabilities in the MediaTek kernel.
