The most permanent alternative is traditional rooting. You will need to unlock the hardware bootloader through OEM unlock toggles or by using MediaTek bypass scripts (such as mtk-bypass via Python). Once unlocked, patch your device's stock boot.img using the official Magisk application, then flash the patched image back to the device via Fastboot.

The error message typically occurs when using MTK Easy SU , a tool designed to provide "bootless" root access to MediaTek (MTK) based Android devices .

The error in MTK-SU occurs when the temporary rooting tool cannot exploit the MediaTek kernel vulnerability, usually because the device's security patch is too new or the incorrect binary architecture (32-bit vs 64-bit) was executed. MTK-SU (MediaTek SuperUser) is a highly popular tool in the Android modding community designed to grant bootless, temporary root access by exploiting a specific security flaw (CVE-2020-0069) found in MediaTek ARMv8 chipsets.
