: If you are doing this manually, consider using the MTK Easy SU app , which automates the process and includes necessary assets that might solve initialization errors .
Navigate directly to that folder and explicitly grant executable rights before running it: cd /data/local/tmp/ chmod 755 mtk-su ./mtk-su Use code with caution. Solution 3: Use Contemporary Rooting Alternatives
This specific "Step 3" failure often occurs when the exploit used by the tool to bypass security measures is blocked or encounters an unexpected system state.
Step 3 failing specifically in "hot" mode is not a random bug. It is a combination of timing, security, and protocol issues. Here are the primary causes:
Now run your original command, but add flags to enforce cold mode and disable handshake retries: mtksu failed critical init step 3 hot
Several factors can contribute to this error. Some of the most common causes include:
To resolve the "mtksu failed critical init step 3 hot" error, follow these troubleshooting steps:
To help narrow down the best solution, could you provide your device's and its current Android Security Patch version ?
The mtk-su tool, developed by developer diplomatic on the XDA Developers Forum and popularized by the Mtk Easy Su GitHub project , provides bootless, temporary root access. It works by exploiting a critical security vulnerability (CVE-2020-0069) present in MediaTek chipsets. : If you are doing this manually, consider
The "mtksu failed critical init step 3 hot" error can occur due to:
: Run chmod 755 mtk-su in your terminal again to ensure it has full execution rights .
MediaTek patched the fundamental vulnerability behind mtk-su (tracked under CVE-2020-0069) in their March 2020 Security Bulletin. If your device has firmware compiled after this date, the kernel driver will safely reject the exploit payload during the Step 3 initialization phase. 2. SELinux Enforcement and setns Violations
The modern gold standard for rooting Android devices involves unlocking the bootloader and patching the stock system boot image. Step 3 failing specifically in "hot" mode is

The vulnerability has been completely closed by the manufacturer. 3. Roll Back Device Firmware (Downgrading)
If using the app, clear the app cache and try again up to 5–10 times. 2. Disable Google Play Protect
