This error indicates that the exploitation process, specifically aimed at gaining root privileges, failed during its critical initialization phase while trying to manipulate the kernel or security mechanisms of the device. What Does "Failed Critical Init Step 3 Hot" Mean?
First, verify whether your device's firmware is actually vulnerable. Go to and check your device's Android security patch level . If the date is after March 2020, the mtk-su exploit will almost certainly fail.

Read/Write operations on direct partition images via download mode.
Flash the older firmware to revert your security patch level back to an exploitable state. Go to and check your device's Android security patch level
If you succeed in using mtk-su to write to the system partition, you might trigger dm-verity . This can cause your device to fail to boot in the future.
The mtk-su binary is a legendary tool in the Android modding community, originally developed by developer diplomatic on the XDA Forums . It provides (superuser status) to devices powered by MediaTek (MTK) ARMv8 chips without requiring users to unlock their bootloaders. The script fails to gain execution control hooks
If you are reading this, you have likely been staring at a terminal window or a flashing red error message on your Android device that reads: For the uninitiated, this string of characters is more than just gibberish—it is a roadblock on the path to rooting or modifying a device powered by a MediaTek (MTK) processor.
