"System purging," the screen flashed.
The most common reason for failure at Step 3 is an outdated binary. Developers frequently update mtksu to support newer kernel versions and bypass minor security updates.
Ensure you haven't selected "Auto." Manually select your specific SoC (e.g., MT6765, MT6762).
In MTK-SU or similar tools, the rooting process follows a sequence:
This error usually means the exploit failed during a specific initialization phase (step 3 of the critical init process). Below is a to understand and potentially fix this issue.
For locked bootloaders where you cannot flash KernelSU, you must brute force the correct memory offset for Step 3. By default, MTKSU fails because it looks for a generic address that your specific SoC changed.
: Most systems and applications log error messages when something goes wrong. Checking these logs can provide clues about what exactly is failing during step 3.
