Boot into Fastboot mode and unlock the bootloader ( fastboot oem unlock or via proprietary brand tools). Extract the boot.img from your current firmware version. Patch that image using the Magisk App .
Manufacturers often release security updates that patch the specific vulnerability mtk-su uses.
If your device is 32-bit, use the version from the arm folder. Step 2: Downgrade Your Firmware (The Most Successful Fix)
maverick:/data/local/tmp $ ./mtk-su --help ./mtk-su: invalid option -- - ./mtk-su: invalid option -- h Failed critical init step 3 1|maverick:/data/local/tmp $ ./mtk-su -v armv8l machine Failed critical init step 3

Because mtk-su cannot force its way through a patched kernel, you must pivot to alternative modification methods: 1. Downgrade Your Firmware
If you are seeing the error , it means the mtk-su exploit tool—used to gain temporary root access on MediaTek-based Android devices—has failed to initialize its core memory manipulation routine. This specific error typically indicates that the exploit has been patched by your device manufacturer or that the tool cannot find the necessary memory offsets to proceed. What is mtk-su?
: If you recently updated your software, the exploit likely no longer works. You may need to downgrade your firmware
Verify your device's architecture before selecting the MTK-SU binary:
: Before accepting any system update, verify whether it will affect your rooting status by checking community forums for your specific device model.
