When managing MediaTek (MTK) devices using Software Upgrade (SU) tools or custom flashing utilities, encountering the error "mtksu failed critical init step 3" can be a frustrating roadblock. This specific error typically indicates a handshake failure between the software exploit and the device's bootloader or security chip.

Uninstall existing MTK drivers, reboot your PC, and install the latest MTK All-in-One Drivers . 2. Use a Hardware "Test Point"
Convert from MTKSU to KernelSU.
